According to the U.S. Environmental Protection Agency, Oregon homeowners could save as much as 20 percent on heating and cooling by sealing and correctly insulating their homes. Different kinds of insulation are appropriate for different areas of your house, and there are also certain types that work best with Oregon’s climate.
R-value rates how resistant insulation is to heat flow. Higher R-value typically means greater efficiency, but you don’t automatically want the maximum R-value in every area. The value you need depends on several factors, including where you plan to install it, your heating and cooling system and your location.
We don’t have the same needs in Oregon that they have in Arizona, and every residence is unique. If you’re planning on adding insulating material, it’s a good idea to have a professional evaluation before making any big changes.
The current R-value minimum requirements of the Oregon Residential Energy Code are:
- Walls: R-21
- Basement walls: R-15
- Flat ceilings (or the floor of the attic): R-38
- Vaulted ceilings (with a slope of 2/12 or more): R-38
- Under the floor: R-30
- Around a heated slab: R-10
- Around a floor perimeter on a concrete slab: R-15
R-value can be affected by where in the home the insulation is installed, and how well it’s installed. For instance, if the insulating material is compressed, it may not live up to its R-value. If it’s not correctly installed in a wall or ceiling, some heat may still escape through the joists and studs. That’s why quality installation is so important to capitalizing on the material’s R-value.
Don’t forget to insulate your ducts, too! A great deal of energy can be lost through leaks and poorly insulated ductwork.
