Spray Foam Insulation in Keller, TX

Keller is mostly residential, but it is not all tract housing. Mixed in with the subdivisions are lots of an acre or more, some with fenced paddocks and a horse barn, others with a detached workshop behind the house. So a Keller project can be two projects: open cell foam under the roof deck of the house, and closed cell foam in the building out back. One free on-site measure can cover both.

Homes in Keller

Keller’s population more than tripled in the 1980s, doubled again in the 1990s and kept climbing through the 2000s. The median Keller home was built in 1999, and about seven in ten were built between 1980 and 2009. Hidden Lakes filled in from the late 1990s through the 2000s. Marshall Ridge came next, building out from 2008 with homes from about 2,500 to 5,500 square feet. Around Old Town Keller, a few houses date back to the 1940s and 1950s.

Like a lot of North Texas houses, these homes sit on slabs, so the air handler and ductwork usually go in the attic. By mid-July a Keller attic can pass 130°F in the afternoon. Air leaves the AC cold and gains heat through every foot of duct before it reaches a vent, and in a two-story the upstairs bedrooms sit right under all of it. More blown insulation on the attic floor does little for the ducts, since they run above it.

For a Keller house we recommend about 5.5 inches of open cell foam, roughly R-20, sprayed against the underside of the roof deck. That seals the attic and brings the ducts and air handler inside the conditioned space, where the air stays much closer to room temperature. If gas appliances share the attic, such as a furnace or water heater, their combustion air has to be checked before the attic is sealed. The full process is on our attic spray foam page.

Shops, barns and acreage lots in Keller

A shop with no ceiling has nothing but the roof panels between the sun and your workbench. If the shop is steel, it also sweats: humid air meets cold steel, water condenses, and it drips onto tools, trucks and whatever is stored inside. Closed cell foam handles both problems. At 2 inches it rates about R-13 and at 3 inches about R-20, and anything from 1.5 inches up also acts as a vapor retarder and makes the panels stiffer. See shop and garage spray foam for workshops and hobby spaces, and metal building insulation for larger steel buildings.

Horse barns need a slightly different plan. If your barn is post-frame with a steel roof, closed cell sprayed under the roof panels cuts the heat coming through them and stops condensation from dripping into stalls and onto hay and feed. Keep the foam on the roof and high on the walls, out of the horses’ reach, and foam the tack room or feed room fully if you want those rooms cooler. Our pole barn insulation page covers post-frame barns and equipment sheds.

Keller spray foam questions

Can you quote the house and the detached shop at the same time?

Yes. One free on-site measure can take in the house, the shop and a barn, and you will usually have the written quote within 24 hours. Expect two foams on it: open cell under the roof deck of the house, closed cell on the steel of the shop or barn. Because the buildings are separate, you can also do the house this year and the shop next year if that suits your budget.

Our upstairs rooms stay hot all summer. Is the attic the problem?

It often is. The second floor sits directly below the attic, and its supply ducts snake through that heat, so the air can arrive warm on a hot afternoon. Sealing the roof deck brings those ducts inside the conditioned space. Foam will not fix an undersized AC unit or a blocked return, though, so if a room still lags after the attic is sealed, have the HVAC system checked.

We’re building on a Keller acre lot. When should the foam go in?

Between rough-in and drywall. Once the framing, wiring, plumbing and HVAC lines are in, but before the walls close, every cavity and the entire roof deck are open. Closed cell in the walls adds stiffness to the framing, and open cell is the usual choice under the roof deck. If a shop is going up on the same lot, put both buildings on the same free measure. Bring us in early so the foam is on the build schedule. More on our new construction spray foam page.
