One Climate Zone Colder Than Lubbock
Spray Foam Insulation in Levelland starts with a detail many people miss: Hockley County is in a colder climate zone than Lubbock County. OpenEI's lists put Hockley County in Climate Zone 4B and Lubbock County in Zone 3B. ENERGY STAR's retrofit guidance follows that line, recommending R-60 for an uninsulated attic in Zone 4B instead of R-49, and R-49 added over 3 to 4 inches of existing insulation instead of R-38. Levelland's own climate numbers show why: January lows average 25.2F and the record low is -16F.
A planned county seat
Levelland was first named Hockley City by Charles W. Post in 1912, became the county seat when Hockley County organized in 1921, and was soon renamed for its flat land. Santa Fe rail service began in July 1925. A 1950s oil boom brought a refinery and gas plant, and South Plains College opened in 1958. A century of growth since then means houses here were built under many different standards.
Housing today
The 2020 census counted 12,652 people and 5,342 housing units, 13.1% of them vacant. Population was down from 13,542 in 2010. The rental vacancy rate was 13.6%, and with a college in town, landlords as well as homeowners look for attic sealing and insulation that make older rentals cheaper to heat and cool.
Heat matters too
Colder winters do not mean mild summers. Levelland's July highs average 92.4F, and the city has hit 115F. Wikipedia notes generally low relative humidity. A well-sealed, deeply insulated attic works in both seasons, and if the ducts are in the attic, foam on the roof deck brings them inside.
Shops, oil field buildings and barns
Cotton and oil both run on steel buildings. Closed-cell foam on shop walls and roofs stops condensation in the cold months and slows the heat in summer.
