Bitumen Roof Insulation

This combination offers the typical advantages of multilayer composites in which the properties of the individual components complement each other.

Bitumen roof insulation.

Closed cell polyisocyanurate foam core. In combination with bitumen it is used for flat roofs. Modified bitumen is compatible with petroleum and so it is possible that it could be installed overtop of an existing tar roof unlike rubber flat roofing which would be eaten away modified bitumen roofing is also very rugged and can sustain a fair amount of foot traffic. Expect to spend one or two days working with a helper to lay insulation and modified bitumen roofing for a 500 square foot roof.

Aluminum foil is used as a vapor barrier for building insulation. Regardless of how the material is applied self adhesive sheets hot mopped asphalt or cold applied adhesives the seams are usually melted together which help stop leaks. Bitumen roofs are one of the longer lasting types of flat roofing materials easily lasting 20 years or more. Before you begin measure and make a drawing of your roof and consult with a dealer.

When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary. Firestone hailgard composite insulation is suitable for epdm tpo modified bitumen and metal roofing systems and specifically designed to protect against accidental punctures and hail. Mineral wool insulation can withstand the high temperatures of both hot bitumen application and heat welders making it ideal in some situations. Mineral wool is also often used as a cover board in asphaltic roof systems because of its fire resistance and dimensional stability.

Provides high r value per inch in built up modified bitumen metal roof and single ply roof systems and utilizes an environmentally compliant blowing agent that provides high thermal insulation performance. A built up roof for example will typically include the built up membrane itself with or without gravel as well as some kind of insulation and cover board which will vary in thickness from roof to roof.
