SIP homes go up faster than traditionally framed buildings. A properly trained SIP installation crew can reduce labor costs by more than 50 percent compared to traditional stick framing, according to a third party study conducted by the R.S. Means unit of Reed Construction Data. Panels can be manufactured as big as 8- by 24-ft., so entire walls can be put up quickly, reducing dry-in time. SIPs can be supplied as ready to install building components when they arrive at the job site, eliminating the time needed to perform individual job site operations of framing, insulating and sheathing stick-framed walls. Window openings may be precut in the panels, and depending on the size, a separate header may not need to be installed. Electrical chases are typically provided in the core of panels, so there is no need to drill through studs for wiring.
