Spray Foam Insulation for Your Roof

Although opting to use spray foam to insulate the walls and ceiling of your home is a decision that needs to be made with great care, it can also be one that pays great dividends in the long term. The basic process of spray foam involves the simultaneous spraying of two different chemicals, with their reaction on contact creating the final substance. When polyurethane and isocyanate are combined they expand to fill a tremendous amount of space, then harden into a permanent bond. The expansion is useful in that it fills a large percentage of the open space that could otherwise conduct heat and cold, while the permanence of the bond means it should not have to be re-applied down the road. There are actually two different types of spray foam; open-cell and closed-cell. Open-cell is dense and spongy and particularly useful for sound control, while closed-cell seals more closely and ends up harder, making it ideal for use as insulation.

Advantages of Spray Foam Insulation

Because it becomes a permanent fixture upon installation, it is a choice that needs to be carefully considered before you make a commitment. For this reason, many people will be cautious and go with more traditional fiberglass insulation. However, depending on the situation, this could be a mistake, as closed-cell spray foam is an extremely effective insulation that provides a multitude of benefits:


This is the whole point, really, and spray foam does an excellent job of it. It expands to fill all available space and provides a very high degree of insulation. Because of its strength and the air-tight seal created by the foam’s expansion, spray foam can almost completely eliminate un-insulated space.

Energy Saver

These highly efficient insulating properties mean that your heating, ventilation, and air conditioning systems have far less air to moderate, meaning less stress on the systems, lower maintenance costs, and reduced energy bills. Standard fiberglass insulation can save you around 30% on your energy costs, and then only if expertly installed for maximum efficiency. Meanwhile, properly installed spray foam can save you roughly 50%, a serious difference in the case of a large home or office building.

Moisture Reduction

Because spray foam creates a complete seal it also serves as a useful moisture barrier. If your roof were to spring even a small leak, fiberglass insulation can quickly become soaked, leading to replacement costs and probably further damage. Closed-cell spray foam, on the other hand, is water repellent, noticeably reducing the risks associated with water leaks.
