✅ Why You Need to Remove Old Insulation Before Spray Foam:
1. Proper Adhesion: Spray foam needs to bond directly to the surface (like wood or masonry). Old fiberglass or cellulose acts as a barrier and prevents it from sticking properly.
2. Maximized Air Seal: One of spray foam’s biggest benefits is its air-sealing ability. If old insulation is left behind, gaps or voids may remain, reducing energy efficiency.
3. Moisture Control: Old insulation can trap moisture, which could lead to mold or rot. Spray foam acts as a v***r barrier when properly installed—only effective if the old, potentially damp insulation is removed.
4. Clean Install: Spray foam expands and hardens. If it interacts with loose or deteriorating insulation, it can lead to an uneven or messy application.
