You Didn't Learn to Ride a Bike Alone, and First-Time SIP Builders Shouldn't Build Alone Either

What first-time SIP builders can expect when they work with ACME.

Somewhere around age six, somebody ran alongside your bike. They kept a hand on the seat while you figured out the pedals, reminded you to keep looking forward, and stayed close until you were steady enough that they could finally let go.

That’s usually how learning something new works. Having someone nearby who already knows what they’re doing makes the unfamiliar a little less intimidating, especially when you’re trying it for the first time.

Building with Structural Insulated Panels (SIPs) isn’t all that different. For a builder who has spent years working with conventional framing, trying a different building system naturally comes with questions. How do the panels go together? What does my crew need to know? How different is the installation from what we’re used to?

Underneath a lot of those questions is usually a more basic concern: What happens when we get to the jobsite and don’t know something yet?

It’s a fair question, and at ACME, the short answer is: you don’t have to go it alone.

The Real Question First-Time SIP Builders Are Asking

Trying a different building system means there are going to be things your crew hasn’t done before. That’s not a reason to avoid SIPs. It simply means having the right support matters, particularly on that first project.

Not every SIP manufacturer treats that support the same way. Plenty are glad to sell you a truck of panels and a set of drawings and call the job done, leaving your crew to work out the rest once it’s all sitting in the yard. If you’ve never installed SIPs before, that can feel less like buying a building product and more like being handed a bike at the top of a hill.

At ACME, support doesn’t end when the panels leave our facility. It starts while the project is still being planned and can continue through manufacturing and installation, depending on what your crew needs.

The goal isn’t to make SIP construction feel complicated. It’s the opposite: we want your crew to understand the system, get comfortable with it, and know someone is there when a question comes up.

Support Starts Before the Panels Arrive

Marking up panel plans before the first ACME SIP ever gets cut

A smoother SIP installation starts well before there’s a truck sitting at the jobsite. The more that can be planned and worked through ahead of time, the fewer decisions your crew has to make in the field.

Before a Single Panel Gets Cut

ACME works from your plans to create a panel layout specific to your project, with the wall and roof panels identified so your crew knows where everything goes. When engineering is required, that becomes part of the process as well.

This upfront planning is an important part of building with SIPs because you’re not simply ordering a stack of building materials and figuring out how everything fits together once it arrives. The panel package is being planned around the home or building you’re actually constructing.

The goal is simple: work through as many details as possible before your crew is standing on the jobsite asking questions about them.

Learn more about ACME’s Project Support.

While Your Panels Are Being Built

Cutting an ACME SIP to size in the manufacturing facility

Once the plans are ready, the SIPs are manufactured for your specific project, with panel sizes, openings, and other details planned before they arrive. Depending on the package you choose, panels can also be prepared and labeled to make assembly easier in the field.

Standard wiring chases are incorporated into the panels, and additional preparation options can reduce the amount of measuring, cutting, and decision-making that has to happen on site. For a crew working with SIPs for the first time, all of that upfront preparation can make the installation process feel much more manageable.

The more that gets figured out before delivery, the less your crew has to figure out while they’re building.

Delivery Day Has a Plan, Too

Before panels ever leave the facility, ACME works through the practical side of getting them to you: whether a tractor-trailer can actually access the site or a smaller trailer or a secondary drop point makes more sense, what’s needed to unload once they arrive, and how panels should be stored so they’re in good shape by the time your crew is ready for them. None of this is exciting. It’s exactly the kind of detail that turns into a scramble if nobody mentions it until the truck’s in the driveway.

The Pre-Install Meeting: Nothing Left to Figure Out On Site

Before installation day, ACME walks your crew through a pre-install meeting, not a formality, but the point where the drawings, the scope, and the actual installation details get covered out loud. What’s included in ACME’s scope and what’s on your crew. How panels should be handled and sealed for your project. How lifting plates work. What to do about rain screens, underlayment, and running electrical through the panels. It’s the difference between your crew showing up to install something they’ve only seen on paper, and showing up already knowing what day one looks like.

When It’s Time to Build, We’re There Too

Installation is usually where first-time SIP builders have the most questions. The panels are on site, the crew is ready to go, and now it’s time to put a building system together that may be different from what everyone is used to.

That’s why ACME offers different levels of installation support. Some builders simply want an experienced person on site while their crew gets started. Others would rather have ACME handle part or all of the SIP installation. How much support makes sense depends on the project and the experience and comfort level of the crew.

Site Supervision

For many first-time SIP builders, site supervision can provide the extra confidence they need without turning the project over to someone else. An ACME site supervisor works alongside your team during installation, helping with sequencing, answering questions as they come up, and showing your crew how the system goes together in the field.

Your crew is still doing the building. They simply have someone beside them who has done it before and can help them get comfortable with the process.

Partial Installation

Some builders are comfortable handling most of the project but would rather have experienced help with certain portions of the SIP installation. Partial installation offers that middle ground, allowing ACME to handle agreed-upon portions of the work while your team takes care of the rest.

It can be a good fit when your crew wants to stay closely involved in the build but would benefit from hands-on support in areas where they have less experience.

Full Installation

For some projects, it makes more sense to have an experienced crew handle the SIP installation altogether. Depending on the project and location, ACME can provide full installation of the SIP package and related structural components.

There isn’t one right level of support for every builder, and that’s really the point. You have options, and ACME can help you decide what makes the most sense for your crew and your project.

We Build With SIPs Too

There’s another reason ACME can help a first-time SIP crew through the process: we don’t only manufacture SIPs. We build with them too.

Taylor Hollow Construction crew framing an ACME SIP wall on site

ACME’s sister construction company, Taylor Hollow Construction, builds with ACME SIPs. That means when our team talks about what happens on a jobsite, where crews tend to have questions, or what can make an installation go more smoothly, that knowledge isn’t coming from a manual alone.

We’ve seen how the panels come together in the real world and worked through the details that are simply part of construction. There’s a difference between knowing how something is supposed to work on paper and understanding what it’s like when you’re standing on a jobsite trying to get it built.

We’ve been on that side of the panels too, and that experience shapes the support we give other builders. The crews ACME sends out for site supervision, partial installation, or full installation are our own people: Class A certified contractors who’ve built SIP walls on a Taylor Hollow jobsite, not just read about them. (More on how each option works on the Installation Support page.)

Full installation makes the most sense for projects near Radford, since travel adds cost the farther the crew has to go. For builders outside that range, most first-time crews do best pairing their own local framing crew with an ACME site supervisor on hand to guide them through the sequence.

ACME is also building out more hands-on training options beyond what’s listed there today, support for getting a crew comfortable with SIPs that goes further than most manufacturers offer at all. If that kind of guidance is what would make a first SIP project feel doable for your crew, it’s worth asking ACME directly about what’s available.

The Kind of Company That Knows Your Project

ACME is a family-owned company based in Radford, Virginia, and we’re still small enough that the person you talk to early in the project may very well be the same person helping answer a question months later.

That kind of familiarity matters when you’re building with something new. If a question comes up, you want to know there’s somebody on the other end of the phone who understands SIPs, knows the building process, and has enough familiarity with your project to help you work through it.

And because construction is construction, questions sometimes come up no matter how well a project is planned. When something unexpected happens on site, our team is there to help figure out the next step and keep things moving. Support shouldn’t disappear the moment the panels are unloaded.

Eventually, We Let Go of the Bike

Remember that person running alongside your bike? Eventually, they let go, and that’s the idea here too.

The goal isn’t for your crew to need help forever. It’s to give you the support you need while you’re learning the system, answer questions as they come up, and help your team get comfortable building with SIPs. Once you’ve seen how the panels are laid out, how the connections come together, and how the installation sequence works, what felt unfamiliar at the beginning starts to make a lot more sense.

And when the next SIP project comes along, your crew isn’t starting from the same place. You’ve done it before.

Trying something for the first time doesn’t mean you have to figure it out alone. Sometimes you just need someone to run alongside you until you’ve got it.

Frequently Asked Questions About Building With SIPs

Do I need experience building with SIPs?

No. Previous SIP experience is certainly helpful, but a builder doesn’t necessarily need to have installed SIPs before taking on a SIP project. Good planning, clear panel layouts, installation information, and access to experienced support can help a first-time SIP crew understand the system and install it correctly. ACME also offers on-site support for builders who want experienced help while their crew gets familiar with the installation process.

What support does ACME provide first-time SIP builders?

ACME’s support begins before manufacturing and can continue through installation. Depending on the project, that can include panel layouts, engineering and project support, panels prepared specifically for the building, installation guidance, site supervision, partial installation, or full installation. The level of support can be matched to the experience of your crew and the needs of your project, so you don’t have to choose between doing everything yourself or turning the entire installation over to someone else.

Does ACME provide on-site SIP installation support?

Yes. ACME offers site supervision for builders who want an experienced SIP professional working alongside their crew during installation. This gives your team someone on site who can help with sequencing, demonstrate how the system goes together, and answer questions as they come up while your crew continues to do the building.

Can ACME install the SIPs for my project?

ACME offers partial and full installation services for qualifying projects. Availability and scope depend on the project and location, so the best first step is to talk with ACME about what you’re building, your crew’s experience, and how much installation support you need.

What if my crew gets stuck or makes a mistake during installation?

That’s exactly what site supervision and partial installation are there for. Your crew has someone experienced on site who can catch a problem before it becomes an expensive one, not a phone number to call after the fact.

Mountain SIP House: A Multi-Generational Home Built for the Long Haul in Riner, VA

Mountain SIP House: A Multi-Generational Home Built for the Long Haul in Riner, VA

finished exterior of a structural insulated panel home

A family wanted out of the suburbs. They wanted land big enough to farm, mountain views, and a home that could hold two generations under one roof without anyone feeling like a guest. What they built in Riner, Virginia, is a home where the downstairs belongs to the younger family and the upstairs belongs to the parents, under a single vaulted roofline that spans 22 feet with no trusses. When it was tested at the end of construction, the blower door came back at 0.69 ACH50, a result that puts this home within reach of Passive House-level airtightness.

This is what happens when a family builds for the long haul instead of the next five years.

Project Highlights

→ 0.69 ACH50 blower door result, well inside the range that defines an exceptionally tight building envelope, which means lower energy use, lower utility bills, and lower carbon emissions over the life of the house

→ Continuous SIP insulation across the walls and roof, with no stud-cavity gaps to sap efficiency the

way stick-frame construction does

→ 22-foot roof panels spanning the full width of the home with no trusses required

→ Multi-generational layout: full downstairs for the younger family, upstairs reserved for parents

and shared gathering space

→ Geothermal HVAC paired with a heat pump water heater

→ Designed and built by Taylor Hollow Construction, ACME’s sister company

→ 2025 SIPA Building Excellence Award, Classic Winner

What is ACH50, and why does 0.69 matter? ACH50 measures how many times the air inside a home would fully turn over in an hour if the house were pressurized to 50 pascals during a blower door test. Lower means tighter. Virginia’s building code requires new homes to test at 3 ACH50 or better. This home tested at 0.69, roughly four times tighter than code requires, and close to the 0.6 ACH50 mark that defines Passive House-level airtightness, the strictest widely used residential efficiency standard. In practice, that means the furnace and geothermal system aren’t fighting drafts, and the mountain wind that would find every gap in a looser envelope has almost nothing to work with here.

The Project

completed custom home in Virginia built by structural insulated panelsThe homeowners were after a specific kind of life: a working plot of land in the mountains, room for the whole family, and a home that would not bleed money in energy costs while they built that life. The design solved for both generations at once. The entire downstairs went to the younger family members. Upstairs held the parents’ quarters and the spaces where everyone gathers. It is one roofline doing two jobs.

Taylor Hollow Construction, ACME’s sister company, served as both builder and design professional on this project, with structural engineering from Pinnacle Engineering, Inc. Taylor Hollow does not theorize about what SIPs can do. They build with them, on their own projects and on client projects like this one, which is exactly why they know where SIP construction earns its keep and where it does not.

The above-grade walls went up entirely in structural insulated panels: 6.5 inches total thickness with a 5 5/8-inch EPS core. The roof used 10.25-inch panels with a 9 3/8-inch EPS core, precut and routed at ACME’s Radford facility before they ever reached the job site.

"Even in the cold months, my 3,000-square-foot home stays warm without needing to use my gas fireplace, and my heating costs have remained surprisingly low."

What SIPs Actually Delivered on This Build

SIP walls being installed on a custom home in Virginia

Three things mattered here, and none of them were marketing claims. They were outcomes.

Faster construction. The 22-foot roof panels spanned the full width of the home without a single truss. That is not a minor detail. Trusses take time to install and add another trade to coordinate. Eliminating them shortened the build schedule and gave the design a vaulted ceiling that a truss system would have made far harder to achieve.

A genuinely tight envelope. The blower door test came back at 0.69 ACH50. For reference, a leaky older home can test above 10 ACH50, and a code-minimum new build often lands somewhere between 3 and 7. A 0.69 result means almost no uncontrolled air movement in or out of the house, which is the difference between a furnace that runs constantly and one that barely has to work. That number is not an estimate. It is a measured result from a test performed on the finished home.

Lower cost through prefabrication, not lower quality. ACME’s precut and routed panels arrived as part of a Ready-to-Assemble package that included precut lumber, rim board, and glulams. That kind of prefabrication cuts on-site labor and material waste, and it is one reason SIP construction can compete with stick frame on total project cost, even though the panels themselves cost more upfront. We break down that math on our Economics of SIPs page.

The Engineering Behind the Vaulted Ceiling

custom home being built with structural insulated panels in VirginaThe 22-foot roof panels are the detail worth lingering on. SIP roof panels carry structural load across their whole span, not just at the points where a truss would bear weight. That structural capacity is what let Taylor Hollow eliminate trusses and open up a vaulted ceiling that would otherwise have required a redesigned framing plan and a bigger labor bill.

The roof panels were also extended past the top plates of the walls to create the home’s overhangs, built into the same panel instead of framed separately afterward. That single move did two things at once: it gave the home the shade and weather protection that keeps a building envelope performing well through Virginia summers, and it removed a framing step that would normally have added time on site.

See how SIP roof spans and design flexibility work on our Designing with SIPs page.

Manufactured at a Solar-Powered Facility in Virginia

Every panel on this home came out of ACME’s solar-powered facility in Radford, VA. Panel waste from manufacturing gets recycled and reused in other industries rather than landfilled. That means lower carbon before the panel ever gets installed, and then a home that uses meaningfully less energy to heat and cool for the rest of its life once it is. For a family building a home meant to hold two generations now and however many come after, that is not a footnote. A home that uses less energy every year produces less carbon every year, for as long as this family lives in it.

Frequently Asked Questions

What does a 0.69 ACH50 blower door result actually mean?

ACH50 measures how many times the air in a home is fully replaced per hour when the house is pressurized to 50 pascals during a blower door test. Lower is tighter. A leaky older home can test above 10 ACH50. A typical code-built new home often falls between 3 and 7. A result of 0.69 means the home has almost no uncontrolled air leakage, which translates directly into lower heating and cooling costs and a more consistent indoor temperature.

Can SIP roof panels really eliminate the need for trusses?

Yes, within span limits that depend on panel thickness and engineering. On the Mountain SIP House in Riner, VA, 10.25-inch SIP roof panels spanned 22 feet with no trusses required, which also allowed for a vaulted ceiling design. Structural insulated panels carry load across their full surface rather than at discrete truss points, which is what makes long clear spans possible. See more on our Designing with SIPs page.

Are SIPs a good fit for multi-generational homes?

SIPs work well for multi-generational layouts because the building envelope performance is consistent throughout the structure, whether the home has one shared HVAC zone or several. The Mountain SIP House used a single geothermal system to condition both the downstairs living area for the younger family and the upstairs quarters for the parents, with the airtight envelope helping the system run efficiently across the whole home rather than working harder in one zone than another.

Where is ACME Panel’s SIP manufacturing facility?

ACME Panel manufactures SIPs at its facility in Radford, Virginia, powered by 360 solar panels. Panel waste from manufacturing is recycled and reused in other industries. ACME serves builders and homeowners across the eastern United States with free shipping within 300 miles of Radford.

How SIP Construction Cut Energy Bills by $1,300 a Year Per Apartment in Blacksburg Affordable Housing

Three-story SIP apartment building with brick base and red panel exterior at Prices Fork Village Apartments in Blacksburg, VA

How SIP Construction Cut Energy Bills by $1,300 a Year Per Apartment in Blacksburg Affordable Housing

Structural insulated panels (SIPs) are high-performance roof, wall, and floor building panels made of a rigid insulation core structurally bonded between two structural-grade facings, used in place of conventional stick framing. They deliver a tighter building envelope, significantly lower heating and cooling costs, and faster on-site assembly. At Prices Fork Village Apartments, they delivered something more specific: $1,300 a year back in the pockets of families who needed every dollar.

When a family is living at 50 to 60 percent of the area median income, $1,300 a year is not a rounding error. That is a car payment. Three months of groceries. Breathing room in a budget that has almost none. It is the difference between a thermostat someone is afraid to touch in January and a home that just stays warm, without a second thought.

That is the real measure of what happened here:  sixteen new apartments in Blacksburg, Virginia, built with ACME Panel SIPs throughout the walls and roof. EarthCraft certified. Energy savings of $1,134 to $1,323 per unit per year compared to conventional construction, or roughly $18,100 to $21,200 in total annual energy savings across all 16 apartments. For the families who live there, those numbers show up every month. In one two-bedroom apartment, that showed up as an electric bill of less than $50 a month, for everything, including heat and air.

Project Highlights

→ 16 new SIP apartments built for families at 50 to 60 percent of area median income
→ $1,134 to $1,323 in annual energy savings per unit vs. conventional construction ($18,100–$21,200 total across all 16 units)

If you have seen what SIPs can do for a custom home, this project shows what they can do for the people who need lower energy bills most.

The Project

Three-story SIP apartment building with brick base and red panel exterior at Prices Fork Village Apartments in Blacksburg, VA

The old Prices Fork Elementary School in Blacksburg had been sitting empty for years. Our sister company, Taylor Hollow Construction, saw what it could become. Today the building houses sixteen apartments for residents 55 and older, Moon Hollow Brewing, Millstone Kitchen (a commercial incubator with a community meal program for low-income residents), and Featherbone Provisions. The school did not get torn down. It became a neighborhood again.

Phase III was where ACME Panel came in. Right behind the historic building, Taylor Hollow broke ground on 16 brand-new apartments using ACME Panel structural insulated panels throughout the walls and roof. Eight three-bedroom units. Eight two-bedrooms. A mix of affordable and market-rate, open to all ages. Completed July 2021.

Why SIP Construction Mattered for Affordable Housing Energy Savings

Newly installed kitchen with dark wood cabinets and dark countertops in a Prices Fork Village Apartments unit, floor still protected during constructionThis was not a luxury development where buyers could absorb high utility costs as a footnote to their mortgage. The affordable units serve families at 50 to 60 percent of area median income. Performance had to be real, and it had to be measurable. For a family already stretching every paycheck, a heating bill that spikes in January is not an inconvenience. It is a choice between staying warm and paying for something else that mattered that month.

ACME Panel 6.5-inch EPS foam core wall panels and 10.5-inch EPS foam core roof panels delivered exactly that. No drafts. No sky-high heating bills in January. Homes that hold temperature the way a well-built home should. The EarthCraft certification confirmed it from the ground up.

Bright bedroom with wood-look flooring, ceiling fan, and large windows overlooking trees in a Prices Fork Village Apartments unitSIP buildings perform this way because the building envelope has no thermal bridging and virtually no air infiltration. Every stud in a stick-frame wall is a thermal break, a path for heat to escape in winter and slip in during summer. A SIP wall eliminates that path entirely. The result is a home that is quieter, steadier, and cheaper to run for its entire life: a bedroom that stays warm on a cold night without the furnace working overtime to keep up.

The families who benefit most from lower energy bills are exactly the ones who can least afford to go without them. That is who SIPs are built for.

Manufactured at a Solar-Powered Facility in Virginia

Every structural insulated panel that went into this project came out of ACME Panel’s facility in Radford, VA, powered by 360 solar panels. Lower carbon in the manufacturing. Lower carbon in the home’s energy use for the entire life of the building. That is not a talking point. It is a physical fact built into every panel we ship. For homeowners, builders, and developers asking how to reduce the carbon footprint of a building without adding cost, Prices Fork Village Apartments is the proof.

Frequently Asked Questions

Can structural insulated panels be used for affordable housing?


Structural insulated panels are particularly well-suited to affordable housing because they reduce long-term operating costs for residents. A SIP building envelope delivers significantly lower heating and cooling bills compared to conventional stick-frame construction — savings that are meaningful month to month for residents at lower income levels. The Old School at Prices Fork in Blacksburg, VA is a direct example: 16 SIP apartments serving families at 50 to 60 percent of area median income, with documented energy savings of $1,134 to $1,323 per unit per year, or $18,100 to $21,200 per year across all 16 apartments.

How much energy do SIP apartments save compared to conventional construction?


At the Prices Fork project in Blacksburg, VA, ACME Panel SIP apartments saved residents between $1,134 and $1,323 per unit per year compared to conventionally framed construction — a total of $18,100 to $21,200 in annual energy savings across all 16 apartments. The savings come from the SIP building envelope’s tight air sealing and continuous insulation, which eliminates the thermal bridging present in stud-frame walls. The building was EarthCraft certified, a third-party verification of its energy performance.

Do SIP homes save money on energy bills?


SIP homes consistently deliver lower energy bills than comparable stick-frame construction. Structural insulated panels provide continuous insulation with no thermal bridging at studs and very low air infiltration, which means less energy is needed to heat and cool the home year-round. Actual savings depend on climate, home size, and energy costs, but real-world projects regularly show 40 to 60 percent reductions in heating and cooling costs compared to standard construction. See how the numbers work on our Economics of SIPs page.

Are structural insulated panels a good choice for multifamily housing?


Structural insulated panels work well in multifamily construction for several reasons. Panels arrive pre-cut to project specifications, which speeds framing and reduces on-site waste. Building envelope performance is consistent across the entire structure because insulation is continuous, not dependent on individual framing quality. For multifamily developers, SIPs also reduce HVAC sizing requirements, which lowers mechanical system costs. For residents, the result is lower utility bills and a noticeably quieter, more comfortable home.

How are structural insulated panels manufactured?


Structural insulated panels are made by bonding a rigid foam insulation core — typically expanded polystyrene (EPS) — between two structural facing panels, typically oriented strand board (OSB). The panels are manufactured under factory-controlled conditions and cut to the specific dimensions of each project before shipping. ACME Panel manufactures SIPs at its facility in Radford, Virginia, powered by 360 solar panels, which reduces embodied carbon in the manufacturing process before the panel ever improves the energy performance of a home.

Who builds with structural insulated panels in Virginia?


ACME Panel is a family-owned structural insulated panel manufacturer based in Radford, Virginia, serving builders, homeowners, and developers across the eastern United States with free shipping within 300 miles of Radford. Taylor Hollow Construction, ACME’s sister company, builds with SIPs as their primary construction method and takes on client projects directly. The Old School at Prices Fork in Blacksburg is one example of what SIP construction delivers in Virginia.

What is EarthCraft certification, and why does it matter?


EarthCraft is a third-party green building certification program for residential and multifamily construction in the Southeast. An EarthCraft certified building has been independently verified to meet standards for energy efficiency, indoor air quality, and construction quality. For affordable housing developments, EarthCraft certification confirms that the energy performance claims are documented and verified, not estimated. The Prices Fork Phase III SIP apartments were EarthCraft certified at completion in July 2021.
