Why This Product Stands Out
Superior Sound Dampening: The dense fiber structure significantly reduces noise transfer between rooms, making it ideal for bedrooms, offices, and media rooms.
Fire Resistant: Non-combustible material provides an extra layer of safety for your home or commercial space.
Easy Installation: These unfaced (UN) batts are designed for a snug friction-fit. Just cut to size and press into the wall cavity—no stapling required.
Sustainable & Safe: Low-dust formulation and formaldehyde-free, ensuring better indoor air quality during and after installation.
Installation Pro-Tip
Since this is Unfaced (UN) insulation, it is perfect for applications where a vapor barrier is already present or not required. If you are insulating an exterior wall in a cold climate, remember to apply a separate 6-mil poly vapor barrier over the studs after the batts are in place.
