Home Insulation Services in Littleton, CO
Littleton’s big temperature swings, from cold winter mornings to hot summer afternoons, put a lot of strain on an under-insulated attic. Many homes in Columbine, Ken Caryl and the older neighborhoods near downtown were built when attic insulation standards were much lower than they are today. Littleton sits in climate zone 5, where ENERGY STAR recommends R-49 to R-60 of attic insulation.
We offer attic insulation, blown-in insulation, spray foam insulation, radiant barriers and complete insulation replacement, along with air sealing to stop drafts at the source. See our Littleton insulation services for more detail.

Littleton Insulation FAQs
Answers to the questions Littleton homeowners ask us most about insulation.
How do I choose an insulation company in Littleton?
Pick a local contractor that looks at your attic before quoting, explains the R-value you have now and the R-value you need, and seals air leaks as part of the job. Thermal Home Solutions is based in nearby Lakewood and starts every project with a free home energy audit.
How much attic insulation does a Littleton home need?
Littleton is in climate zone 5, where ENERGY STAR recommends R-49 to R-60 in the attic. Many older Littleton homes have far less than that. During your audit we check what’s there and tell you how much to add.
Should I choose blown-in or spray foam insulation?
Blown-in insulation is usually the most cost-effective way to bring an open attic floor up to R-49 or more. Spray foam costs more but insulates and air-seals in one step, which makes it a good fit for rim joists, cathedral ceilings and tight spaces. We’ll recommend the right option for each part of your home.
Which Littleton neighborhoods do you serve?
We work throughout Littleton, including Historic Downtown Littleton, Columbine, Ken Caryl and TrailMark, and in nearby Highlands Ranch, Centennial and Lakewood.
