Homes throughout the Pacific Northwest date back to the late 1800s. Many earlier homes were insulated using materials, such as newspaper and corn cobs, while others lacked any insulation. Neither of these factors would meet today’s energy standards! To make your home more energy efficient, air sealing and insulation is recommended.
The fact is that upgrading to current ENERGY STAR recommendations reduces one of the biggest energy expenditures facing your home: Heating and cooling. For Washington, which ENERGY STAR classifies as Zone 4, add R38 to R60 insulative materials to reap the advantages of attic insulation.
Advantages of Attic Insulation
- Increased comfort
- Reduced noise pollution
- Easier to maintain temps
- Lower heating and cooling costs
- Helps to extend the life of HVAC equipment
- Quick returns on investment when professionally installed
Deciding What Insulation Type is Best
There are two main types of insulation used in an attic: Blown-in and spray polyurethane foam (SPF). Both require professional installation. Special equipment and safety measures must always be adhered to. Fiberglass and cellulose are the two most popular materials for blown-in. Inch for inch, they provide affordable R-values and heat retention. Cellulose also provides a dense, effective barrier against moist air leakage.
The other type of insulation, spray polyurethane foam is available as open-cell or closed-cell. SPF offers stellar thermal performance. Once applied, it quickly expands, effectively filling the most minuscule gap or crack. Here’s looking at you nail holes! This type of insulation can be used in roofing and interior wall cavities. It is also good for adding thermal resistance to irregularly shaped areas.
