How to Choose a SIP Company?
How do you pick the right manufacturer? Below, you’ll find nine questions that will help you pick a SIP company through the noise:
1. Is it really a SIP?
Some companies sell “structural insulated panels” that aren’t actually SIPs! Instead they sell pre-built panels with metal or wood framing inside, negating the effects of continuous insulation without the same testing, strength, and proven performance. The building code is very specific about what makes up a SIP. Make sure you are getting the real thing.
2. Is the company established at least 10 years ago, and does it have a history of projects that have stood the test of time?
How long has the SIP company been in business? A body of work that has stood the test of time is one of the best indications of reliability. Otherwise, you may be making a decision based on faith. A warranty doesn’t mean anything unless a company has been around to demonstrate the reliability of its product.
3. Are they a SIPA member in good standing?
All of the major manufacturers of Structural Panels belong to the Structural Insulated Panel Association. SIPA membership indicates the member has:
- a current code report that demonstrates panels tested for performance
- a quality control program with quarterly audits by a third party that monitors how panels are made to performance standards
- committed to an ethical code of conduct.
- has worked extensively to make SIPs the preferred building system
SIPA Members are the proven best panel companies. It pays to choose a SIPA member!
4. Do they have a code report? How good is it?
Check https://www.sips.org/resources/building-codes for the latest manufacturer code reports. The SIPA Code report that ACME uses has been developed by 10 leading manufacturers at a cost over $500,000 and is widely recognized as the best in the industry, setting common standards for SIPs.
5. Are they using experimental techniques or skins?
Don’t let your house become a science experiment. Some companies use other materials instead of SIP Grade OSB and don’t tell you what it is made of. While they make a lot of claims, this should be a red flag. SIPs have decades of testing behind them, and many of the alternatives haven’t been tested. Adding an additional layer, such as Zip Board, has the potential to trap moisture from inside the house, leading to mold and rot. Additionally, some companies use lesser-grade materials, resulting in a weaker SIP.
6. What kind of builder support do they provide?
Ask these questions:
- Have they built with SIPs as a builder?
- Will they train your crew?
- Will they offer a supervisor?
- Will they put SIPs up for you?
- Will they offer a RTA package that provides the lumber cut so you install faster?
Incorrectly installed SIPs can lead to problems down the line. Be sure your manufacturer offers the hands-on supervision or training your builder needs.
7. Do they have a formal quality control program with ICCES or NTA with Quarterly Inspections?
These third-party testing audits occur on a semi-annual basis and ensure quality and consistency of product.
8. How close is their plant to your jobsite?
Being close to the manufacturer offers several real advantages, including lower delivery costs, less carbon emissions, and the speed at which replacement panels can be delivered if a mistake is made on the job site. All else being equal, choose the local manufacturer.
9. Is the company the right size for your project?
At ACME, we still get excited for every size project, big or small! We also provide builder support for many of our smaller builders who have never worked with SIPs before. Make sure the SIPs manufacturer you choose provides the guidance and attention you need!
