Contractor Tips: Spray Foam vs. Radiant Barrier Sheathing

December 17, 2019 2:46 am Published by Leave your thoughts

Radiant barrier sheathing and spray foam insulation are two great options for homes and commercial buildings, but which one is right for your project? Each comes with its own specific set of benefits and drawbacks. The main difference is that radiant barrier sheathing provides reflective thermal radiation, whereas spray foam insulation creates a noise barrier that many people find helpful. Read on for more information from the best insulation contractors in Fargo, ND.

Spray foam insulation

Spray foam insulation is just what it sounds like: a sprayable foam that expands to fill cavities in your wall space or attic. It’s a great way to not only provide airtight insulation, which will keep the extreme temperatures at bay, but it also prevents mold and mildew and provides a thick sound barrier. It can last several decades when properly installed.

Spray foam insulation can be more expensive to install, and it’s not necessarily the best choice for your attic—it doesn’t provide a way to cool the outside of your roof, which can cause your shingles to deteriorate faster than normal. However, when properly installed by the best insulation contractors in Fargo, ND, it is an extremely effective method to keep your energy bills low.

Radiant barrier sheathing

Radiant barrier sheathing is great for your attic—its foil surfaces reflect heat and prevent it from entering your attic space in the summer. It can actually reduce temperatures by up to 30 degrees Fahrenheit, making it a passive energy saving system that can last for decades. Because attics are often the hottest part of a home (heat rises, as you may know), using this method can keep the attic space significantly cooler, which makes it easier for your HVAC system to maintain the desired temperature.

Unlike spray foam insulation, radiant barrier sheathing does not raise the shingle temperature significantly, making it a better attic choice for most buildings. One drawback, however, is that it can only be installed when the roof is being replaced. The foil needs to be placed reflecting into the attic, and requires proper ventilation.

Unfortunately, these two methods cannot be used in conjunction in your attic, as the spray foam would prevent the reflective properties of radiant barrier sheathing from fully working. Depending on your individual home or building, you might find that either radiant barrier sheathing or spray foam insulation is better for your needs. Be sure to ask your contractor about their suggestions and why one method may be more efficient.
