Spray Foam Insulation on Signal Mountain

Spray foam for Signal Mountain homes

Signal Mountain is a town of about 8,900 people on the south end of Walden Ridge, with its southern edge overlooking the Tennessee River about 1,000 feet below. US 127 climbs the mountain from downtown Chattanooga, about eight miles away. The name comes from Signal Point, used for signal fires and later as a Union signal station in the Civil War. Families moved up the mountain to escape epidemics in the 1870s, and Charles E. James developed much of the town in the early 1900s.

Mountain weather

Life on the mountain is a little different from the valley. Winters are colder, and snow and ice that melt quickly in Chattanooga can linger on the mountain. Wind on the ridge pushes air through every gap in a house. Summers are a bit milder but still humid. That makes air sealing especially valuable here, because wind-driven drafts are a big part of winter heat loss.

Homes we see

Signal Mountain has historic cottages and homes from the town’s early years, many with small attics, crawl spaces and stone foundations. Mid-century homes fill many streets, and larger newer homes have been built on wooded lots throughout the town.

Where foam helps

• **Rim joists and crawl walls.** Stone and block foundations on older homes leak a lot of air. Closed-cell foam seals and insulates them.
• **Attics in older homes.** Shallow attics with little insulation benefit from foam’s higher R-value per inch.
• **Large homes with ducts in the attic.** Foam on the roof deck keeps the ductwork inside the insulated shell.
• **Vaulted ceilings.** Cathedral ceilings with little room for insulation are a good fit for closed-cell foam.

Older homes

Historic homes need extra care. We check wiring, roof condition and moisture before insulating. Stone foundations can let in water and must be dry before foam goes on. We also look at fireplaces and gas appliances that need combustion air.

Snow and ice

When ice builds up at the roof edge on cold days, heat escaping through the attic is often the cause. Sealing the attic floor and adding insulation keeps the roof colder and reduces ice at the eaves.

We also serve Walden, Fairmount and other communities on Walden Ridge. Send your ZIP to confirm coverage.

Wooded lots on the mountain also mean leaves in gutters, which can lead to roof-edge leaks. We check for old water stains before foaming a roof deck.
