Cellulose Insulation Installation Tips

This type of attic insulation can be installed using one of two methods. Dry cellulose can be damp sprayed or blow in behind netting, either in new construction or in retrofit applications. It can also be dry sprayed, as in timber frame construction, with a small amount of water added at the spray nozzle to moisten the material and help it adhere to wall sheathing.

The blow-in method is typically used in existing homes and can be done over drywall or if the wall finish has already been removed. The nozzle of the blower is placed in the lower hole and the cellulose is forced into the space, filling all open cavities between studs. It can even be blown around obstructions, such as pipes, electrical wires and plug sockets, creating a tight seal that prevents cold bridges.

It has a higher recycled content than fiberglass and is more energy efficient, holding in heat in the winter and keeping it out in the summer. It is also made from paper, so it’s environmentally friendly and is often recycled after use, preventing it from sitting in landfills. It is also treated with fire retardants, including ammonium sulfate and boric acid, to ensure it meets all regulatory standards for building materials.

If cellulose is not installed properly, moisture can compromise its effectiveness and lead to mold growth. A reputable installer will be trained to air seal and follow industry leading practices that will prevent moisture issues and create an evenly distributed cavity.
