SIPs are part of the answer. Architectural trends are quick to change. For example, on a summer afternoon with a 90 degree F outside temperature and cooler inside temperature, the conduction heat flow moves toward the inside. Consistent volume compared to insulation voids, compression and aging. More consistent interior temperatures.
Thermal mass is an under-valued factor in energy efficiency.
Structural Insulated Panels are an excellent energy efficiency alternative because they are efficient in all four areas. These increases in a down construction year are common for our industry and point out that demand is always high, but we've always had a problem finding builders willing to try something new. When projects start disappearing, builders go where the work is, and suddenly SIPs look appealing to them. This is an excellent time to build with SIPs. Energy efficiency will be critical at re-sale time, builders are available, SIP prices are low, and financial institutions are looking to lend money.
