When an attic is missing insulation, it is no wonder the rooms below it are cold! Before blowing in cellulose to the higher R-60 value, our insulation team sealed the air leaks in the structure and around the light fixtures.
This home had a lot moisture under it, plus there was little to no insulation on the underfloor. To help with both issues, these McMinnville, OR homeowners chose closed-cell spray foam insulation as it is a better and longer-term solution. Their floors are much warmer now, too!
Besides helping make this homeowner more comfortable, the spray foam on the underfloor in the crawl space helps to deter rodents. They love to use fiberglass as nesting material, so instead of re-insulating with more fiberglass, he chose the better and longer-term solution of closed-cell spray foam.
This "before" photo of this Corvallis attic shows how the pink insulation is really just an air filter. The pink insulation is no longer pink since air carrying the dirt and nasty mold was leaking up through the ceiling into the attic. See those lines radiating out? That is where dirt and mold were collecting! This "after" photo shows the same attic, with all the leaky areas sealed up before our crew blew in the cellulose insulation. The homeowner is now much more comfortable in this older home.
The couple that owns this Corvallis, OR home knew there were insulation issues under their home. When our Energy Consultant crawled under to investigate and take photos to show the homeowner, besides all the insulation sagging and falling down (see BEFORE photo), there was a large rodent infestation!
They moved forward with a crawl space encapsulation to address the insulation issues, the rodent infestation, and the high humidity level.
