Identificación de fugas de aire
Punto críticoCómo verificar
1. On a windy day, hold a lit incense stick near windows, doors, outlets, and light switches — smoke wavering indicates air leak
2. Check weatherstripping on all exterior doors — should seal tightly all around
3. Check window caulking — no gaps between frame and wall
4. Feel around electrical outlets and switches on exterior walls — air leaks common here
5. Check attic access hatch/door — should be insulated and weatherstripped
6. Inspect rim joist area in basement (where framing meets foundation) — major leak point
7. Check plumbing and wiring penetrations through exterior walls
8. Check fireplace damper — should close tightly when not in use
