This product category refers to fiberglass insulation batts, designed with a facing material (such as paper or foil), sold at a specific home improvement retailer. The “R19” designation indicates the material’s thermal resistance value; a higher R-value signifies greater insulating capability. This type of insulation is commonly used in residential construction for walls, floors, and ceilings to reduce heat transfer.
Properly installed, this product enhances energy efficiency by maintaining consistent indoor temperatures, leading to reduced heating and cooling costs. Its availability at a major home improvement store provides accessibility for both professional contractors and do-it-yourself homeowners. Historically, faced insulation has been used to control moisture and act as a vapor retarder, contributing to a healthier indoor environment by preventing mold and mildew growth.
