Modular “SIPs” or Structural Insulated Panels were first designed by Avalon Building Systems. These panels are used in their modular homes. SIPs are prefabricated insulated sides of the modules which make up the walls, ceilings, floors, and roofs. They provide more superior and uniform insulation than stud or "stick frame" construction, with energy savings of 12%–14%. Because of their insulating qualities, SIPs also make the home quieter. These modular homes easily exceed "Energy Star Standards" and are certified to meet LEEDS platinum standards for new residential construction. LEED certification is based on a point system in which a building can obtain a Certified, Silver, Gold or Platinum level certification and is an internationally recognized certification system that measures how well a building performs in energy savings, water efficiency, CO2 emissions reduction, improved indoor air quality, and more.
Structural Insulated Panels are made in a factory and shipped to the manufacturing facilities. Manufacturers then connect them together to construct a house. When using SIPs, the speed of construction is much faster than stick built residential construction. Shells can be erected quickly, saving labor time and money, without compromising quality. These savings help compensate for the fact that SIPs usually cost more than other construction systems, but through the modular manufacturing process which is far more efficient than traditional construction, the overall costs are much lower, so the higher costs of SIPs are negated.
