Spray foam is a popular insulation application, and for good reason. Its outstanding insulating properties make it a great choice to increase energy efficiency. Still, when deciding on new insulation materials for your home, it’s best to evaluate your options. Here are 3 things to know about spray foam insulation:
- There are two types of spray foam insulation. It will either be open-cell or closed-cell foam. Open-cell spray foam has tiny pockets that do not completely seal, which makes it more malleable even after it dries. Closed-cell foam is far more dense than open-cell as it is completely packed closed. This means closed-cell foam is more moisture-resistant than open-cell foam, but it is also more rigid. Open-cell foam provides a good sound barrier between walls, while closed-cell foam is ideal in areas where optimum thermal resistance and water barriers are needed.
- Spray foam offers exceptional insulation properties. While closed-cell spray foam has a higher R-value (thermal resistance) than open-cell foam, both offer quality insulation for your home. Spray foam insulation can fill nooks and crannies far better than fibreglass insulation, offering a more complete thermal barrier. This results in reduced heat transfer and air leakage, which translates into better energy efficiency throughout your home.
- Spray foam is more difficult to install than fibreglass insulation. DIY spray foam kits are available on the market, but spray foam is difficult to work with and is a messy process to install. What’s more, inadequate spray foam installation forfeits the benefits of the product. Professional installers have the training and equipment to ensure an optimal application, so every last inch is properly filled.
