“Sips” is an acronym. It means “structurally insulate panels”. These panels consist of a layer of thick urethane foam that is sandwiched between two layers of 1/2″ plywood. The panels can come in several thicknesses but is most popular in the 4 1/2″ width. This exterior only wall system is used in place of the 2x studs that are commonly used as the structure . The speed in which the walls are raised (affecting on labor cost), and the freedom to hang components (cabinets, interior pictures, exterior siding, ) without having to locate studs, and very straight walls make this type of construction favorable to home owners. Plus the insulation value (both thermal and sound) are excellent. The Panels arrive at the job site pre-assembled and ready to stand-in-place. Some companies will offer to cut window and door openings. This is not a new product in the industry and more question can be answered by searching the internet.
