Roof sarking and roof membranes are both installed beneath roof cladding, but they serve different purposes. Roof sarking is mainly used to reflect radiant heat and provide an extra layer of weather protection, while roof membranes focus more on water resistance, breathability and moisture control. Understanding the difference helps you choose the right roofing underlay for your climate, roof design and insulation requirements.

Aluminum Foil Woven Fabric: Why It Can Reflect Up to 95% of Radiant Heat

2026-07-03

Aluminum foil woven fabric is often described as a reflective insulation material, but the working idea behind it is fairly direct. It reflects a large part of incoming radiant heat instead of absorbing it, mainly through a continuous aluminum surface supported by a stable woven structure. The real performance depends less on the material name and more on surface condition, installation method, and whether an effective air layer is formed in the system.

5 Key Parameters You Must Check When Purchasing Aluminum Foil Woven Fabric

2026-07-02

In aluminum foil woven fabric procurement, performance is never determined by appearance or price alone. It depends on several key technical parameters hidden within the structure of the material. Basis weight, aluminum layer thickness, tensile strength, width specification, and composite barrier performance together define how the material behaves in real applications.
