Application of fiberglass cloth in building exterior wall insulation

Fiberglass cloth plays an important role in building exterior wall insulation, mainly used as a reinforcement material to improve the crack resistance, durability, and safety of insulation systems. The following is an analysis of its specific applications and advantages:

1、 The role of fiberglass cloth in external wall insulation

Enhance the crack resistance of the insulation layer

Fiberglass cloth can significantly improve the tensile strength and impact resistance of insulation layers, effectively disperse stress, and avoid cracking caused by temperature changes, external impact, or material shrinkage.

In the external wall insulation system, fiberglass cloth is usually used in combination with plastering mortar to form a thin anti cracking layer, ensuring the integrity and stability of the insulation layer.

Improve the durability of the insulation system

Fiberglass cloth has good weather resistance and corrosion resistance, which can resist the effects of ultraviolet rays, acid and alkali erosion, and humid environments, extending the service life of insulation systems.

Alkali resistant glass fiber cloth (such as AR alkali resistant glass fiber containing zirconia) can form a protective film in alkaline cement environment to prevent fiber corrosion and ensure long-term performance stability.

Prevent insulation layer from falling off

Fiberglass cloth is tightly combined with insulation materials and plastering mortar to form a solid overall structure, effectively preventing the insulation layer from falling off due to weak bonding and improving the safety of building exterior walls.

2、 The advantages of fiberglass cloth in external wall insulation

Lightweight and high-strength

Fiberglass cloth is lightweight, but has high strength and modulus, which will not increase the load on building exterior walls, and can significantly improve the mechanical performance of insulation systems.

Convenient construction

Fiberglass cloth is easy to cut and lay, can adapt to complex exterior wall shapes and structures, has high construction efficiency, and is easy to composite with other materials.

Strong adaptability

Fiberglass cloth can be used for various exterior wall insulation systems, such as rock wool board, polystyrene board, rubber powder particles, etc., to meet the needs of different buildings.
