Spf Foam Roofing

Spf roofs are installed by spraying a liquid on the existing roof and allowing it to expand into a foam.

Spf foam roofing.

Foam roofs have no seams to split or pull apart and allow water to enter. When it comes to choosing the best overall insulation product for your low slope roof it s hard to beat a tried and true product like polyisocyanurate iso panels. Most of the causes of additional roofing expenses don t exist when you have a foam roof system. Although there are reasons that a building will need a thicker layer the most common reason is for energy efficiencies.

Because of this spf roofing can only offer a theoretical r value. Insulating freezers tanks and other structures spray foam is frequently used to insulate and protect a wide variety of special structures. The aldocoat spf and coating system is a two product roofing system that features an aldocoat elastomeric fluid applied roof coating applied over basf spray polyurethane foam spf. A thick typically 1 5 thick closed cell polyurethane waterproofing barrier seals the roof against leaks.

A protective surface is then applied to the foam to provide an added barrier against the elements.

Spray polyurethane foam spf is the only roofing material that has no seams. Aldocoat coatings are a great choice over sloped metal roofs because they leave very little ponding water and provide waterproofing uv protection and fire resistance. Insulation properties of spray foam roofing spray foam has an r value of 7 14 per 1 inch thickness enabling it to provide more thermal resistance with less material than any other type of roofing insulation. Transfer pumps are used to get the components to a proportioning unit that properly meters the two at a one to one ratio and heats and pumps them through dual hoses.

The dura foam roof system has a rigid and durable surface that you can walk on. Because spf is hand applied the roof s ultimate r value is determined by the thinnest spot in the foam layer. The thicker you make the foam layer the high r value your roof will have. After cleaning the existing roof the spf roof can be applied directly over asphalt shingles concrete metal and wood.
