Is Spray Foam Insulation Good for All Climates?
Spray foam insulation has gained popularity for its energy-saving benefits and airtight sealing. But many homeowners wonder — is spray foam insulation good for all climates, or only useful in extreme hot or cold regions?
The answer: Yes, spray foam insulation works well in nearly every climate — when installed properly. Let’s break down how.
How Spray Foam Works
Spray foam insulation expands to fill cracks, gaps, and cavities. It creates an airtight seal that resists airflow and moisture, unlike traditional fiberglass or cellulose insulation.
There are two main types:
-
Open-cell spray foam: More flexible, better for interior walls and soundproofing.
-
Closed-cell spray foam: More rigid and dense, ideal for exterior walls, roofs, and extreme weather conditions.
In Hot Climates (like Texas)
In places like Dallas, where summer heat can be brutal, spray foam blocks radiant heat from entering your home. This lowers the load on your AC system, reducing cooling costs by up to 40%.
It also prevents humidity from creeping into attics and crawl spaces, helping reduce mold and mildew.
In Cold Climates
In northern states or mountain regions, closed-cell spray foam keeps warm air inside during the winter months. It performs exceptionally well in places where temperatures drop below freezing, helping reduce heating costs and preventing pipes from freezing.
In Moderate or Coastal Climates
Spray foam still excels in places with mild or damp climates, thanks to its moisture resistance. It also provides structural support, making it a great long-term investment for coastal homes exposed to high humidity or salty air.
