Rigid insulation has a high R-value due to its density and materials used. It is more efficient than other insulation but can be more expensive. Higher R-values allow for less insulation to be used, but initial costs may be higher. Long-term savings in heating and cooling costs make up for the higher cost. Rigid insulation […]
Insulation reduces heating and cooling costs and provides temperature uniformity. R-value measures insulation’s efficiency in blocking heat transfer. Increasing thickness increases R-value, but insulation can’t block heat loss through windows. Vacuum and Airgel® insulation have high R-values. The necessary R-value depends on climate and heating/cooling type. Low R-value insulation still improves efficiency, and insulation should […]
