https://www.homebuildingandrepairs.com/repairs/insulation/index.html - Drafty old home? Think twice before you fill those walls with insulation! In this video, we explain why adding modern insulation to a house built before modern weatherproofing can actually destroy it. We break down how historic homes were designed to breathe and rely on empty wall cavities to dry out wet lumber. You'll learn exactly why trapping moisture with blown-in insulation acts like a giant sponge, leading to devastating mold, mildew, fungus, and wood rot. If you are renovating a historic property, watch this before making a costly mistake!
