Roofing nonwoven fabric is a functional material used in building roof engineering, usually polyester fiber, polypropylene (PP) and other raw materials, by acupuncture, thermal bonding and other non-woven process made. With its light weight, waterproof, weather resistant, tensile and other characteristics, it has become an important part of modern roof waterproof, insulation, isolation system. The following is a detailed analysis from three aspects: functions, application scenarios and advantages:

First, the core function of the Roofing nonwoven fabric

Waterproof and moisture-proof

As a substrate or insulation layer for waterproof coils, non-woven fabrics can effectively block rainwater penetration and achieve air permeability through the microporous structure between the fibers, avoiding the accumulation of water vapor inside the roof and reducing the risk of mildew.

Enhanced tension and puncture resistance

Non-woven fabrics have high longitudinal and transverse tensile strength, which can disperse the stress caused by temperature changes or external forces (such as trampling, hail) on the roof, and protect the waterproof layer from tearing or puncture.

Isolation and buffering

In multi-layer roof structures, non-woven fabrics can separate different materials (such as asphalt layer and insulation layer) to prevent adhesion or chemical reactions, while buffering the deformation pressure caused by thermal expansion and contraction.

Auxiliary thermal insulation

Part of the roof non-woven fabric and thermal insulation material composite use, through the fiber structure to reduce heat conduction, improve the energy saving effect of the roof.

Second, the unique advantages of roof non-woven fabrics

Lightweight construction

Compared with traditional materials (such as linoleum), non-woven fabrics are light in weight and easy to cut, which can greatly reduce roof load and improve construction efficiency.

Strong weather resistance

Through UV resistance, high and low temperature (-40℃ to 120℃) treatment, adapt to extreme weather, extend the service life of the roof.

Environmental protection and economy

Part of the roof non-woven fabric can be recycled to reduce construction waste; And its long life and low maintenance costs, reduce the full cycle of use costs.

Flexible adaptability

It can be customized according to the requirements of gram weight (such as 100-500g/㎡), thickness, color, to match different roof structures (flat roof, slope roof) and engineering standards.

Third, the typical application scenario of roof non-woven fabric

Waterproof coil base material

With asphalt, polymer material composite made of waterproof coil,

Roof insulation

It is laid between the insulation layer and the waterproof layer to prevent the dissolution or deformation caused by direct contact between the insulation material and the asphalt.

Planted roof system

Used in roof greening projects, as an anti-root puncture layer or drainage layer, not only to protect the waterproof structure, but also to promote drainage ventilation.

Metal roof liner

Non-woven fabric is laid under the metal roof to reduce the erosion of condensate on the structure, while providing sound insulation and heat insulation effects.
