Transmet Aluminum Flakes have been successfully used since 1980 in many roofing applications.  Over 100 million square feet of roofing surface has been covered by our aluminum flakes.

Transmet Aluminum Flakes have a total solar reflectivity of 80%.  The unique high purity aluminum alloy that Transmet uses is extremely durable and will maintain its reflectivity.  Transmet flakes are 100% aluminum.  Typical coverage is 3-lbs per 100 square feet.

Transmet sells Aluminum Flakes in two (2) main applications which are Factory Applied and Site Applied.

Factory Applied flakes are applied in the shingle or roll roofing manufacturing plant.  In most cases only minor modifications are needed in standard roofing equipment to apply the flakes.

Site Applied Roofing flakes are applied at the building roofing site.  Typically a cold process roofing material is built up with layers of fiberglass or polyester.  After the final coating of asphalt is applied flakes are deposited onto the surface of the roof.
