Product Introduction

We can provide various waterproof and vapor-proof veneer materials required for glass wool felts for steel structures, and process and compound them on glass wool felts in the original factory to meet various environmental requirements. It can greatly reduce the loss of heat and cold, not only has a beautiful appearance, but also has excellent moisture-proof and heat-insulating properties.

Application

It is widely used in steel structure buildings, especially in roof systems.
