Analysis of the application of glass wool felt in the roof insulation of steel structure factory buildings
2025-12-10       Source:

In steel structure factory construction, the roof is the area where heat exchange is most significant. To reduce indoor temperature increases in summer and heat loss in winter, glass wool felt has become a commonly used roof insulation material. This article will explain its performance characteristics, installation methods, and usage precautions.


I. Main Performance Advantages of Glass Wool Felt


1. Stable Thermal Insulation: Glass wool felt has a large number of uniform and fine fiber structures, which can effectively block heat conduction.


2. Strong Sound Absorption: Steel structure factory buildings have many equipment and high noise levels; glass wool felt can reduce reverberation and improve the operating environment.


3. Lightweight and Convenient Construction: The roll form facilitates large-area installation, improving construction efficiency.


4. Enhanced Moisture Resistance with Aluminum Foil Finish: Prevents condensation or moisture absorption on the roof, thus avoiding a decline in thermal performance.


II. Applicable Fields


Steel structure factory roofs


Metal sandwich roofs


Large-span warehouse buildings


III. Construction and Installation Methods


1. Used in conjunction with metal roof panels: Lay the glass wool felt on top of the purlins, then cover with the roof panels.


2. Overlapping sections should be 50-80mm to reduce thermal bridging.


3. Fixing method: Secure with metal strips and screws to maintain wind resistance.


IV. Precautions


Keep the material dry to avoid water absorption.


Keep the aluminum foil facing inwards during installation.


Do not compress the material to avoid affecting the thickness and insulation effect.


V. Summary


Glass wool felt, as a common insulation material for steel structure roofs, can significantly improve the building's energy efficiency and also has sound absorption advantages, making it a stable and reliable insulation solution for factory construction.
