While NCFI 2020 PLUS® a very high R-value, R-value is not the only factor affecting insulation efficiency. Homes insulated with 2020 PLUS® will consistently outperform homes insulted with glass fiber batts, even with equal R-value in the walls. The reason is air flow. When the wind blows, the thermal efficiency of glass fiber batts plummets. Costly house wraps, with their seams and imperfections, cannot compensate for this loss in efficiency.
With NCFI 2020 PLUS® spray foam insulation, high thermal efficiency is maintained, regardless of the weather, and house wraps are not needed.
Conserving energy reduces fossil fuel consumption and the attendant pollution. Building your home to be comfortable for your family and friendly to the environment will actually pay for itself and save you money as long as you live in your house. |
