Spray Foam Insulation in Cloverdale, CA

Spray Foam Insulation in Cloverdale has to deal with real heat. Wikipedia classifies Cloverdale as a hot-summer Mediterranean climate (Köppen Csa), different from the warm-summer Csb of Santa Rosa and Petaluma, and notes that temperatures can exceed 100°F and summers are hot and dry compared with the rest of Sonoma County.

What that means

Attic heat is the main comfort problem. Sealing the attic floor and adding depth toward R-49 cuts the heat coming down into rooms. In homes with ducts in the attic or vaulted ceilings, spray foam under the roof deck brings the ducts inside the insulated space.

A railroad town

Cloverdale incorporated in 1872, when the San Francisco and North Pacific Railroad arrived. Older homes near downtown often have thin attics and empty walls.

Owners

The 2020 census counted 3,524 housing units, 95.5% occupied, with 64.7% owner-occupied.

Winter

Summers are hot, but winters are still cool and wet, and floors over open crawl spaces get cold. R-19 under the floor helps.

Older downtown and newer edges

Cloverdale's older homes near downtown date to its railroad years and often have thin attics and empty walls. Newer homes on the town's edges usually have some attic insulation that can be topped up and sealed. Both benefit most from attic work in this climate.

Typical plan

Seal the attic floor (top plates, can lights, flues, hatch), add blown-in toward R-49, and install eave baffles to keep vents open. Where ducts are in the attic, consider foam under the roof deck. Then insulate floors and walls as budget allows.
