Which Insulation is Best for Your Climate?

which insulation is best for your climate

When selecting insulation for your home, it’s important to consider various factors such as the climate you’re in. To help you out, the pros at DFW Thermal have created a quick and helpful guide on which insulation is best for your climate.

Best Insulation R-Values Based on Climate

When it comes to selecting insulation based on climate, the first thing you should do is look into the recommended insulation R-values, which vary throughout the United States. R-Value is a numerical rating that indicates an insulation’s ability to resist heat traveling through it. The higher the R-Value, the higher the insulation’s heat resistance.

If you’re looking into recommended R-values, start by looking into the Department of Energy’s recommended R-values based on climate zones. Various regions are divided up into 8 climate zones—zone 1 includes the lowest R-Value recommendations while zone 8 includes the highest. If you’re in the Dallas- Fort Worth area, you are most likely in zone 3. This means an uninsulated attic here will require insulation with an R-value range of R-30 to R-60 and an uninsulated floor requires an R-value range of R19-R25.

Best Insulation Types Based on Climate

Now that you know the best insulation R-Values based on climate, it’s also important to investigate the best insulation MATERIALS based on different climates. Keep in mind that R-Value and insulation material go hand in hand—certain materials have a higher R-Value than others.

  • Fiberglass Insulation for Cold Climates

If you live in a particularly cold climate, consider going with loose-fill fiberglass insulation. This insulation material has a high R-Value range of R30 to R60, making it perfect for climate zones that come with high R-Value recommendations. Plus, loose fill fiberglass is non-flammable and on the relatively cheaper side with a price range of $0.45 to $2.25.

  • Radiant Barrier Insulation for Hot and Sunny Climates

If you are in a warmer and particularly sunny region (Texas!), consider going with Radiant Barrier insulation. This type of insulation is vastly different from other insulation materials which rely on thermal resistance to insulate homes—this means its insulation capabilities can’t be measured by R-Value. Made of reflective material like aluminum foil, radiant barrier prevents excess heat gain by reflecting heat away from your home. If you’re worried that going with radiant barrier might be a bit of a risk, consider its long-term rewards; according to the Department of Energy, radiant barrier can lower cooling costs by up to 10% in warm and sunny regions.

  • Spray Foam Insulation for Humid Climates

If you live in a region where humidity is an issue, go with spray foam insulation. This type of insulation has the look of shaving cream when it is applied but turns into a durable barrier when it cures. It can get into gaps and cracks, prevent air leaks but most importantly, it minimizes moisture. This way, spray foam prevents moisture damage, rot and mold growth.
