Why fiberglass is important for roof waterproofing
Improve waterproofing effect
Fiberglass has extremely low water absorption and can effectively prevent moisture penetration and prevent moisture from entering the roof. This is very important for protecting the internal structure and equipment of the building and can extend the service life of the building.
Enhance mechanical strength
Fiberglass has high tensile strength and tear resistance, and can maintain stable performance in harsh environments. This not only improves the durability of the roof, but also reduces maintenance costs.
Excellent weather resistance
Glass fiber has good tolerance to natural factors such as ultraviolet rays and acid rain, and can maintain its performance for a long time under various climatic conditions. This not only extends the service life of the roof, but also reduces maintenance costs.
Fire resistance
Many types of glass fiber have good flame retardant properties, which can delay the spread of fire when a fire occurs and improve the safety of the system. For example, high-silica fiber is not easy to burn at high temperatures, and even if it burns, it will not produce a lot of smoke, reducing the danger in the fire.
Environmental protection and sustainability
Glass fiber does not contain substances that are harmful to the human body and meets environmental protection standards. Some types of glass fiber can also be recycled and reused, reducing the generation of waste and meeting the sustainable development requirements of modern buildings.
Types of glass fiber and their characteristics
Roofing mat
- Features: Roofing felt is a non-woven fabric formed by fixing randomly distributed glass fibers together through a mechanical needle punching process. It has many advantages such as light weight, high strength, high temperature resistance, and corrosion resistance.
- Application: Widely used in roof waterproofing projects, providing excellent waterproofing performance and durability. Suitable for roof waterproofing in various climatic conditions, especially for occasions requiring high weather resistance and mechanical strength.
Chopped Strand Mat
- Features: Chopped Strand Mat is made of randomly distributed chopped glass fibers and has good waterproof performance and corrosion resistance. However, its strength is relatively low and it is not suitable for roofs that bear large external forces.
- Application: Mainly used in the manufacture of composite materials such as hand lay-up process and compression molding. Although it is not suitable for large-area roof waterproofing, it performs well in local repair and reinforcement.


Polyester Mat
- Features: Polyester mat is made of polyester fiber and has good flexibility and corrosion resistance. However, its high temperature resistance is poor and it is not suitable for roof waterproofing in extreme environments.
- Application: Suitable for interior decoration and some occasions that do not require extremely high weather resistance. Due to its good flexibility, it is often used for waterproofing of curved surfaces.
Mesh Cloth
- Features: Mesh cloth is woven from criss-crossed fibers and has high tensile strength and good air permeability. However, its waterproof performance is relatively weak and cannot completely prevent moisture penetration.
- Application: Mainly used for wall reinforcement and crack repair, enhancing the stability and durability of the structure. Although the waterproof performance is not as good as other materials, its reinforcing effect is significant.

Choose the most suitable type of fiberglass for roof waterproofing
Consider weather resistance
It is very important to choose fiberglass materials suitable for local climatic conditions. If it is located in an area with strong sunlight and large temperature difference, it is recommended to choose roofing felt or high silica fiber materials with strong UV resistance and high temperature resistance.
Evaluate mechanical strength
For roofs that need to withstand greater external forces, such as coastal areas with greater wind pressure or cold areas with heavy snow loads, roofing felt or mesh cloth with higher tensile strength and tear resistance should be selected.
Pay attention to fire resistance
If the building has higher fire protection requirements, it is recommended to choose fiberglass materials with good flame retardant properties, such as high silica fiber roofing felt, to improve the safety of the system.
Consider the convenience of construction
Different fiberglass materials have different requirements during the construction process. Roofing felt is soft, easy to cut and shape, and can be customized according to the specific size of the roof, which greatly simplifies the construction process. In contrast, mesh cloth requires a more complex installation process.
Budget and cost-effectiveness
When choosing fiberglass materials, you also need to consider the budget and cost-effectiveness of the project. Roofing felt and chopped strand mats are usually reasonably priced and suitable for large-scale applications; while polyester felt and mesh cloth may be more suitable for small areas in specific occasions.
How to choose fiberglass according to specific needs
Understand project needs
First, clarify the specific needs of the project, including the structural type of the roof, the climate conditions, fire protection requirements, and construction difficulty. This will help determine the most suitable fiberglass material.
