Bitumen Roof Insulation

Laying of bitumen membranes on a flat roof.

Bitumen roof insulation. Bitumen roofs are one of the longer lasting types of flat roofing materials easily lasting 20 years or more. 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. Before you begin measure and make a drawing of your roof and consult with a dealer. Mineral wool is also often used as a cover board in asphaltic roof systems because of its fire resistance and dimensional stability.

Rigid roof insulation board. Mineral wool insulation can withstand the high temperatures of both hot bitumen application and heat welders making it ideal in some situations. 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. Aluminum foil is used as a vapor barrier for building insulation.

When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary. This combination offers the typical advantages of multilayer composites in which the properties of the individual components complement each other. 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. Closed cell polyisocyanurate foam core.

In combination with bitumen it is used for flat roofs. Start to finish 2 days.
