Homes Below the Rim
Spray Foam Insulation in Ransom Canyon is a different job from the flat-land suburbs. The town sits inside Yellow House Canyon at the eastern edge of the Llano Estacado, where the North Fork Double Mountain Fork Brazos River has been dammed to form Lake Ransom Canyon and Buffalo Springs Lake. Wikipedia lists 16.38% of the town's area as water. Homes sit on the canyon slopes and near the water, and many have rooflines, vaulted ceilings and dormers that are harder to insulate than a simple ranch house.
Vaulted ceilings and custom roofs
Where a ceiling follows the roof, there is no attic to fill with loose insulation. Batts in rafter bays leave gaps and often lack room for proper venting. Spray foam applied to the underside of the roof deck fills the full depth of the rafter and seals the joints in one pass. Closed-cell reaches more R-value in a shallow rafter; open-cell is lighter and less costly where depth allows. We pick the foam based on rafter size and the R-value target.
A small, established town
Ransom Canyon had 1,011 people and 412 housing units in 2000, and 1,189 people in 2020. In 2000 its median age was 45. Many homes here are decades old, and in hard-to-reach roof spaces the original insulation is often thin, settled or incomplete.
Notable houses
The town is home to sculptor Robert Bruno's Steel House, a 110-ton weathering-steel house on four legs above the canyon rim. Most houses are more conventional, but complex rooflines, dormers and knee walls are common enough that foam, which handles odd shapes well, is often the right tool.
Climate
Ransom Canyon has a semi-arid climate (BSk), and it is in Lubbock County, which OpenEI lists in Climate Zone 3B. ENERGY STAR recommends R-49 for an attic with no insulation there. Rooms with big windows and vaulted ceilings take on summer heat quickly, so the roof plane matters even more.

Ransom Canyon Questions
How do you insulate a vaulted ceiling?
We spray foam on the underside of the roof deck between the rafters, which fills the full cavity and seals it. That works from inside when the ceiling is open, such as during a remodel or a new build.
Can foam help with a hot great room?
Usually the roof is the main source of heat in a vaulted room. Foaming the roof deck slows that heat. Large windows add heat too, which insulation cannot change.
Do you work on lake homes with tricky access?
Yes. Tell us about the access when you call, and we will plan the hose route and equipment.
