Insulation in the Windmill City
Spray Foam Insulation in Sterling City deals with some of the widest temperature swings in the region. Sterling City's 1991-2020 climate data list a record low of -13F, colder than San Angelo's, alongside a record high of 112F and a July average high of 93.5F. The town sits on the Edwards Plateau along the North Concho River at about 2,287 feet.
A planned county seat
R.C. Stewart donated the townsite in January 1891, H.B. Tarver platted it that February, and it became the county seat the same year. The city incorporated in 1955 when its population was about 800. It calls itself the Windmill City, and these days most of its windmills are large turbines on a ridge about 20 miles northwest of town.
Housing
The 2020 census counted 1,121 residents and 435 housing units, 9.7% vacant, with a homeowner vacancy rate of only 0.4%. Homes are lived in and rarely come up for sale. Many are older houses that have been kept up over the years, and a good attic seal and fresh insulation can make a real difference in both summer and winter.
Shops and barns
Steel buildings around Sterling City see hard freezes and hot summers. Closed-cell foam handles both condensation and heat.
Targets
Sterling County is in Climate Zone 3B per OpenEI. We aim for R-38 to R-49 in attics.
Wind and weather
Turbines on the ridge northwest of town are a reminder that this is windy country. Wind pushes air through every gap in a house, which makes air sealing especially worthwhile here. Gaps around windows, doors, plumbing, wiring and the attic hatch all add up, and a house that feels drafty in a north wind usually has open paths at the top plates and the attic floor.
Older homes
The population fell by about 10% during World War II and the city incorporated in 1955, so a share of the housing dates from the 1950s and earlier. Those homes tend to have thin attic insulation and few air seals. Sealing first and blowing in to depth is usually the best value.
