Frequently Asked Question
How long does it take wet insulation to dry?
Drying time for wet insulation depends on type, ventilation, temperature, and humidity. If it doesn't dry within 2-3 days, it should be removed to prevent mold and wood decay.
Which way should insulation face?
Insulation should face the living space, with the vapor barrier (the paper or foil backing) towards the interior to help control moisture.
How long does insulation last?
Insulation typically lasts 20 to 30 years, though some types, like fiberglass and rockwool, can last up to 50 years.
