Snow & Ice

UV Exposure


FlexClad-400™ is a 45 mil, pre-fabricated self-adhering, sheet-type protective membrane. The outer layer is an embossed, UV-resistant aluminum weathering surface. Under the aluminum are multiple layers of tough, high-density cross-linked polymer film. Under the polymer film is a uniform layer of aggressive rubberized asphalt adhesive which sticks directly to metal, insulation facers and most other clean, dry surfaces. The self-adhesive surface is protected by a disposable release liner.

FlexClad 400 Color Options

Aluminum, White, and Almond


Designed specifically to protect ductwork and sub-grade applications, FlexClad-400 can be applied over rigid board insulation, cold pipes, plenums, storage tanks, iron, copper, steel, PVC, CPVC and concrete. FlexClad can be used for piping systems, pipelines and other below grade structures. The product weatherproofs, resists water leaks and vapor transmission, preserves the efficiency of thermal insulation and reflects sunlight to reduce interior temperatures.  FlexClad-400 is designed for exterior, interior or sub-grade use and it may be used in direct burial applications.
