A Ready to Assemble package is where ACME not only pre-cuts the windows, doors, roof slopes and details out but also pre-assembles all insert lumber where possible, and labels lumber pieces to make installation easier on site. Ask for an RTA when talking with an ACME representative if you are interested in speeding up your installation.
If needed ACME can embed I-joists at the seams of 4’ panels in order to span further distances should your project require it.
