Spray Foam Insulation in Cadiz, KY

Spray Foam Insulation in Cadiz covers both an old county seat and the lake country around it. Cadiz was platted in 1820 on Robert Baker's land as the seat of Trigg County, and it sits close to Lake Barkley, east of the Land Between the Lakes recreation area. The 2020 census counted 2,540 residents and 1,270 housing units, 13.8% of them vacant.

Lake houses and cabins

Some of those vacant units are second homes and rentals near the lake. Lake houses often have vaulted ceilings, decks, lower levels on sloped lots and crawl spaces that see a lot of humidity. When a house sits empty for weeks, a sealed crawl space with a dehumidifier protects the framing and ducts.

Vaulted ceilings

Cabins with cathedral ceilings have no attic to fill. Closed-cell foam under the roof deck reaches a high R-value in a shallow rafter bay without needing vent space.

Older homes in town

Homes around downtown Cadiz include older frame and brick houses on crawl spaces. The usual plan: seal the crawl space, foam the rim joist, seal the attic floor and blow in loose fill to depth.

Climate zone

OpenEI lists Trigg County in Climate Zone 4A. ENERGY STAR's targets there are R-60 for an attic with no insulation and R-19 for a floor over a crawl space.

Older brick homes

Some of the older homes around the courthouse are brick. Brick walls are handled carefully because moisture needs a way out; we focus on attics, floors and rim joists in those houses rather than filling masonry walls.
