HD Spray Foam is a high-tech green building material that helps you save energy in your home. It insulates better than fiberglass and cellulose, and can help reduce your heating and cooling costs. Plus, it creates a barrier that blocks out pollen, pollutants, irritable dust and unwanted noise, making your home healthier, quieter and more comfortable for everyone.

Using a special spray gun, contractors apply the insulation directly to walls, joists and ceilings, or to a wood frame before drywall goes up. The foam expands and fills every nook and cranny to avoid air leakage that can lower your energy efficiency. This type of insulation can help you avoid drafts and cold floors, and is especially effective in basement rim joists, crawl spaces, attics, overhangs (or cantilevers), knee walls and bonus rooms.

Spray Foam Insulation vs. Traditional Insulation: Which is Right for You

Both open and closed-cell foam insulation provide good R-values per inch of thickness. However, closed-cell foam is physically stronger and more durable, and also creates an effective vapor barrier that helps prevent moisture build-up in wall cavities. It is a bit more expensive than open-cell foam, but it provides more energy savings over the long run.

It’s important to have a professional install spray foam insulation since it contains volatile organic compounds that can off-gas for a while after it dries. The contractor should use indoor heating and portable heaters to warm the installation space and keep it within the optimal temperature range for the product to work properly.
