How ‘green’ are Timberline SIPs?
Timberline SIP buildings are some of the most energy efficient buildings ever developed. Most of the energy used in homes is for heating and cooling. The exterior shell of the building is critical for energy efficiency and occupant comfort. Timberline SIPs make use of a thick core of Expanded Polystyrene (EPS) which creates both high R-Values (a measure of the resistance to the passage of heat) and low U-Values (a coefficient of heat transfer). Foam construction eliminates the voids and thermal bridges common in conventional stud framing and Fiberglass insulation. In SIP construction the rigid insulation blankets the entire structure in a well-sealed envelope. Less air leakage means fewer drafts, less sound transmission, and a much more comfortable indoor environment. Molds, mildews, and dust are reduced. SIP-enclosed buildings are more fire resistant than stick frame buildings because there are no air cavities in the walls to create the ‘chimney effect’. Air temperature and quality ar
