This BEFORE photos shows the attic deck floor and ductwork. What you can’t see is: how inefficient the fiberglass batting is, how the ducts were leaking, and how there were air gaps along the edges that were causing air to be sucked up from the home and into the attic!
Fiberglass, although still be used, is not the best insulation material. Building standards back when this home was built in 1926 didn’t include sealing up all the leaks. To solve many issues, the homeowner chose closed-cell spray foam insulation (see AFTER photo).
The Eugene-area client already had our company insulate their attic and they were ready to have the crawl space encapsulated so chose us for that work as well. The BEFORE photos shows the old-inefficient insulation falling down. The AFTER photo shows the encapsulated crawl space. Their goal was to make their house cheaper to heat and cool. By insulating and sealing both the attic and the under floor, this goal was accomplished!
No wonder these Eugene, OR homeowners were not comfortable inside their home-what was underneath was a mess! It was very moist, mold was growing, insulation was missing in places, and mice were living under there.
Since about half the air they were breathing in their home was coming from that crawl space, the owners chose to encapsulate their crawl space. This seals the house from the ground, handles water issues (they needed two sump pumps), and makes it much harder for critters to live under there.
To help make their home more comfortable and energy-efficient, this Eugene, OR couple chose closed-cell spray foam (AFTER photo) to replace the inefficient fiberglass batting insulation (BEFORE photo) that was in their attic. This spray foam seals air leaks and makes a nice impenetrable “blanket” in their attic. It also deters rodents as they cannot nest in it like they prefer to do in fiberglass.
Being cold in their new home is not what these Eugene, OR homeowners were expecting! To solve this, they chose the longer-term solution of closed-cell spray foam applied to the underfloor in the crawl space. They told us they noticed an immediate improvement!
