SIP homes are basically panelized homes by a different name. The S.I.P.s used in SIP homes are basically two pieces of load-bearing material sandwiched around an insulating core. These panels reduce the need for using separate structural and insulating elements in the construction of exterior walls; instead of erecting a http://spetstech.net78.net lumber frame and adding insulation between the studs, SIP homes are constructed with each of these elements contained in uniform, extremely sturdy panels. The S.I.Ps themselves are more expensive as a material than lumber and rolled or batt insulation, but the quickness with which SIP homes can be built can often make up the difference in initial cost by reducing labor hours. Environmental Benefits of Panelized Home Construction. With so many people becoming increasingly concerned with the material waste and energy expenditure common to traditional home construction, panelized homes are a welcome breath of fresh air.
