Thermal Insulation

Why choose fiberglass? It’s ideal for thermal insulation. When properly installed, it fills cavities and slows down the transfer of heat through attics, ceilings, ducts, floors, piping and walls. Typically, it can even be installed more cost-effectively than other insulation materials while helping to maintain the desired temperatures of heated or cooled spaces.

Fiberglass insulation can make buildings and the equipment operating inside them more thermally efficient and consume less energy. That’s why fiberglass is the preferred choice for many building owners, contractors, professional remodelers, specifying engineers and architects. 

The insulation's resistance to conductive heat flow is measured by its thermal resistance — R-value. The higher the R-value, the greater the insulating effectiveness. For residential projects, contractors, professional remodelers and do-it-yourselfers should carefully follow directions on the insulation packaging to achieve the expected R-value. Avoid compressing the insulation less than the labelled thickness on the package when it is installed. Compressing it will reduce the thermal performance of the material.
