Insulation for a 1940s home in Portland

Casey and Jared bought a home in NE Portland
. Built in the 1940s, it had little insulation in the attic and none in the walls or crawlspace. Their upstairs bedroom got so hot that it could barely be used in the summer.

That's when they hired GreenSavers. We partnered with Craft3 to secure low-interest financing and insulated the home from top to bottom. With comprehensive air sealing, attic insulation, wall insulation, floor insulation, and rim joist insulation, their home performs much better. Casey and Jared can now comfortably use their upstairs bedroom and rest easy this summer.

Attic, wall, and floor insulation



So how do we install insulation? Learn more about what it means to install attic insulation, wall insulation, and crawlspace insulation in Portland and Bend. We‘re one of the most experienced home insulation specialists in Oregon.




"One of the most cost-effective ways to make your home more comfortable year-round is to add insulation to your attic." - US Department of Energy. We typically insulate attic floors with blown-in cellulose insulation, producing R-50 at a depth of 16 inches. We also insulate attic kneewalls with fiberglass batts and wrap with a Tyvek air barrier. If you'd like to use the floor of your attic for storage, we can either build a platform above the blown-in cellulose or, as an alternative to cellulose, install rigid foam board insulation on the attic slopes.



In a home without wall insulation, about 35% of heat loss occurs through wall cavities. As recommended by the US Department of Energy, we insulate walls with dense-pack cellulose insulation, typically installed from the exterior without any alteration to the appearance of the home. Our process: (1) Remove sections of siding. (2) Drill into the sheathing and dense pack each cavity to R-15. (3) Plug holes, reinstall siding, and touch up paint. Adding wall insulation is your single biggest opportunity to improve the comfort and efficiency of your home.



If you have a crawlspace, it is critical to insulate the ceiling of the crawlspace - ensuring that the insulation does not sag or droop - and install a vapor barrier on the ground. An effective vapor barrier slows the growth of mold and mildew. According to David Hales at Washington State University, about 40% of the air we breath at home originates in the crawlspace. If you have a full basement, the best approach is to add insulation to your rim joist, which is the area around the perimeter of your home where it sits on the foundation. To insulate a rim joist, we typically recommend rigid foam board insulation, which has the highest insulation value per square inch and serves as an effective air barrier.
