This modern approach of insulated vinyl siding can help homeowners save energy. It is recognized by most energy codes and government programs. Insulated siding is commonly confused with mere vinyl siding. However, the energy savings are quite different, being non-existent with mere vinyl siding. Both the U.S. Environmental Protection Administration (EPA) and the Department of Energy (DOE) recognize the benefits of insulated siding as it relates to energy efficiency. This is partially due to the federal mandate from the Federal Trade Commission on vinyl siding manufacturers. This mandate requires them to test and prove any claims about R-value before marketing their product.
It is also important to note that the U.S. Census Bureau recognizes vinyl siding as the top selling exterior cladding in the U.S. and it has been added to the list of approved building products that can help qualify new homes under the ENERGY STAR program. It can aid efficiency professionals, designers and builders to meet or exceed climate zone requirements. The R-values for insulated vinyl siding are commonly R-2, R-2.5 and R-3. This refers to the capacity of an insulating material to resist heat flow. In simple terms, the higher the R-value the greater the insulating ability. This product can also be used to meet a requirement for the U-factor of a wall assembly. The U-factor takes into account all the wall’s elements combined when determining its thermal conductance.
Many people think the only way to boost wall insulation in an existing building is with an invasive procedure. It requires drilling holes between the wall studs and fire breaks and then filling the voids with insulation. These holes are patched and painted but often leaving traces of rework behind. Another approach is available from the vinyl siding industry that can work independently or in conjunction with upgraded wall insulation.
