Why Your Newly Insulated Room Still Feels Cold
Albany – September 07, 2026 -- Homeowners who install new insulation but still feel cold drafts may be missing a critical second step: air sealing. According to insights shared in a HelloNation feature, insulation slows heat transfer through walls, floors, and ceilings, but it does not stop air from moving through cracks and gaps.
Small gaps let conditioned air escape even in fully insulated homes
Common trouble spots include window frames, door thresholds, attic hatches, and areas where pipes or wiring pass through exterior walls, says Darren Haggett, Branch Manager and Insulation Expert at Builders Installed Products of New York LLC in Albany, New York. Rooms above garages, additions, and spaces near exterior corners are especially prone to temperature swings because they contain more seams and transitions where air can move freely.
