Before you begin measure and make a drawing of your roof and consult with a dealer.
Bitumen roof insulation.
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.
Laying of bitumen membranes on a flat roof.
Start to finish 2 days.
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.
Aluminum foil is used as a vapor barrier for building insulation.
Rigid roof insulation board.
In combination with bitumen it is used for flat roofs.
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.
Closed cell polyisocyanurate foam core.
Mineral wool is also often used as a cover board in asphaltic roof systems because of its fire resistance and dimensional stability.
Expect to spend one or two days working with a helper to lay insulation and modified bitumen roofing for a 500 square foot roof.
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.
