Spray Foam Insulation in Oregon

In most Oregon buildings the gain comes from air sealing rather than raw R-value. Western Oregon has a long, damp heating season, and a building that leaks air is expensive to heat and slow to dry out. Spray foam seals and insulates in one application, which is why it outperforms batts in older housing stock.

Closed-cell has the higher R-value per inch and doubles as a moisture barrier, which suits crawl spaces, rim joists, roof decks and metal buildings. Open-cell costs less per board foot and seals air just as well, which often suits interior walls and ceilings where sound matters more than moisture. We assess the building before recommending either.

Often, yes. Vented crawl spaces were designed on the assumption that vents dry the space out. In much of Oregon, and especially on the coast, those vents let in air that is already saturated, which then condenses on cooler surfaces underneath the house. Sealing and insulating the crawl space changes how the space behaves rather than treating the symptom.

It depends on the area, the foam type and installed thickness, access, and preparation. That is why estimates are free and written. You get a clear scope and price before any work begins.

We work across Oregon, from the coast through the Willamette Valley and Portland metro to Bend and the Rogue Valley. Our office is in Eugene. If you are unsure whether we reach you, call and ask.

Yes. Retrofit work in existing buildings is the majority of what we do, including removing or working around older material where needed.
