If you’ve decided that foam insulation is right for your Austin, TX, home, you may still be faced with the decision of what type of polyurethane spray insulation to choose. Polyurethane foam is sprayed into wall and floor cavities as a liquid, then it quickly hardens into a solid, impermeable barrier that promotes energy efficiency and provides protection from outside elements.
Foam insulation comes in two types: open-cell and closed-cell, and there are numerous differences that impact the performance that you can expect in residential or industrial settings.
- Closed-cell is a higher density foam which provides a moisture vapor barrier, which means that moisture will not pass through the foam. It has a higher R-value, is more rigid, and is more expensive than open cell. Because close-cell foam does not allow moisture to pass, it could trap moisture under roof decks and therefore should not be used in the roof’s wood decking. This insulation is best used in refrigeration, industrial, or marine settings.
- Open-cell insulation is basically made up of billions of tiny broken bubbles which allow moisture to pass and would be suitable for use around the roof, and is usually a better choice for most residential applications. It is more flexible than closed-cell foam insulation which means that it will “give” with your home during high winds, and is usually the most suitable foam for residential settings.
Regardless of which type of foam insulation may be more suitable for your needs in Austin, both closed- and open-cell insulation can reduce energy consumption, prevent mold growth, and make the walls of your structure stronger.
