How Fiberglass Batt Insulation Helps Prevent Heat Loss in Winter
Fiberglass batt insulation reduces winter heat loss by creating a thermal barrier that traps air in millions of tiny glass fibers, slowing the transfer of heat through walls, ceilings, and floors. Properly installed fiberglass batts with an R-value of R-13 to R-21 in walls and R-30 to R-60 in attics can reduce heat loss by 30-50% compared to uninsulated spaces. This translates to indoor temperature…
