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.

Product Performance

Prevent water vapor penetration

High tensile and bursting strength

Correctly selecting moisture-proof veneer can not only protect building components and indoor working environment, but also make indoor light soft and bright, beautifying the appearance.

The moisture-proof veneer has better tensile strength and bursting strength, and does not require wire mesh support during application. It has extremely high construction convenience and excellent cost-effectiveness, better insulation and decorative effects, and lower overall cost.
