Types of Attic Insulation

While kitchens and bathrooms get most of the attention when it comes to home improvement, a well-insulated attic can provide several other benefits for your home. In addition to saving on energy costs, proper insulation will help stabilize indoor temperatures throughout the house and prevent hot/cold air movement from room to room.

Attic insulation is rated by its thermal resistance, or R-Value, with higher ratings indicating better ability to resist heat flow. Different insulation materials have advantages and disadvantages; working with a professional who understands your attic space can ensure the most optimal choice.

Eco-Friendly Attic Insulation Solutions from 316 Insulation of Olympia

Reflective insulation is a foil-faced product that reduces radiant heat transfer and can be used as an additive or a stand-alone insulator. This type of insulation is most effective in warmer climates and is great for reducing cooling costs. However, it is not a good solution in damp or moist environments because it can promote mold and mildew growth.

Fiberglass batts or rolls are flexible sheets of fiberglass or fiberglass-coated cotton that lay within the standard spacings in wall studs and floor joints. This type is economical and easy to install, but may not be appropriate for uneven spaces or where wires or pipes are located. These materials also tend to settle over time, reducing their effectiveness.

Cellulose is a natural material made from recycled paper and other plant-based materials, treated with fire retardants and injected into attics to form a dense barrier against heat loss. This type is eco-friendly and has a high R-value per inch; it is also moisture-resistant. However, the chemicals in this type of insulation can irritate skin and eyes, so protective equipment is required during installation.
