SPF (Spray Polyurethane Foam) is a spray-applied insulating foam that is installed as a liquid and then expands many times its original volume. A 100% chemical bond means a permanent, one piece, and watertight seal around roof penetrations and along edges. SPF is a closed cell roofing and insulation material that forms a seamless, monolithic barrier that prevents air and water infiltration.
SPF systems (Spray Polyurethane Foam) are referred to as "self-flashing" because they can be applied to vertical surfaces such as parapet walls and roof penetrations in a continuous manner, thus eliminating seams and cold joints - the main source of roof leaks.
If you still aren't convinced that Spray Polyurethane Foam roofing isn't one of the best roofing options around, consider the following:
- SEAMLESS - seamless, airtight waterproof system - it eliminates leaks.
- INSULATES - has the highest "R" (6.88) value providing more thermal resistance of any roofing product on the market.
- WATER & AIR TIGHT - The closed cell structure of polyurethane foam resists the penetration of water and air.
- LONG LIFE - Lasts indefinitely, needing only minor repairs instead of complete removal/replacement like other systems.
- LOWERS SURFACE TEMPERATURE - On a summer day Polyurethane Foam is an average of about 100 degrees as compared to up to 200 degrees for traditional roofing systems, saving your cooling costs and stress on your HVAC units.
When choosing an SPF Contractor Make Sure To Ask About Their Installers Experience and Training. There is nothing more difficult than trying to restore or fix a poorly applied SPF roofing system. It can be one of your biggest nightmares if it is not installed correctly. Make sure that your contractor installs a quality Acrylic Resin and that it is “gauged” to ensure proper millage.
