Adhesive is a good idea, but is only necessary in high wind areas or where specifically required by the engineering or panel plans. Kneewall Header - The kneewall and header attachment is critical to transfer the roof or floor load evenly through the panel. Please see Figure H below for the method of attaching the kneewall and header panels to adjacent panels. Bucks - Bucks are the dimensional lumber which line doors and windows and allow attachment of the doors and windows. Beam Pocket - Beam pockets spread the force of the point loads for structural beams and allow for even support from posts or splines.
SIPs are the best possible humidity control to allow long term aging of the frame.
This reduces twisting and checking. The reduced labor and quicker close-in translates to reduced final cost on the structure. Nothing insulates better than SIPs. Often, gable ends are much more cost effective and easier to do in SIPs. Occasionally, a bump out or bay can be done with SIPs more easily.
