"When training ensures the proper design and installation, a SIP envelope can meet all the consumer's expectations. SIPs provide lower energy costs, reduce our carbon footprint and provide a safer, cleaner and structurally superior building system," says Cobb. "Pre-planning in a SIP build is an important part of the process. You need to be considering issues such as proper HVAC sizing, sealing strategies, electrical issues. The R-value benefits provided by SIPs are significant, but unless you're installing these panels correctly you might as well just leave your windows open."
