Holikme Twin Door Draft Stopper

Heavy-duty structural isolation sweep for basement cold sinks

Permanently block the "weight" of cold air from unconditioned zones like basements or garages. This double-sided thermal sweep slides under the door to create a mechanical seal, preventing freezing drafts from undercutting your heat pump's output and siphoning warmth from your living space.
