Nonwoven Polyester Felt for Waterproofing

As waterproofing systems evolve to meet the growing demands of durability and sustainability, the choice of base materials becomes increasingly critical. Among various options, nonwoven polyester felt has emerged as a preferred solution for high-performance waterproofing membranes and roofing underlays.

🔍 What is?

Nonwoven polyester felt is a fabric made from short polyester fibers bonded together by mechanical, thermal, or chemical processes. Unlike woven fabrics, nonwoven felt does not require weaving or knitting. This results in a flexible, durable, and uniformly textured material that performs exceptionally well in waterproofing applications.

✅ Key Advantages of Nonwoven Polyester Felt:

Dimensional Stability
The structure offers excellent resistance to stretching or shrinking, even under temperature fluctuations and mechanical stress.
Superior Water Resistance
Its dense fiber distribution ensures low water absorption and acts as a reliable barrier for waterproofing systems.
Chemical Resistance
Polyester-based felt resists degradation from most construction chemicals, acids, and alkalis.
High Tensile Strength
Despite being lightweight, it maintains strong mechanical performance, making it suitable for long-lasting use.
Environmentally Friendly
It is recyclable and often made using eco-conscious manufacturing methods.

🏗 Applications in the Construction Industry

Bitumen-based waterproof membranes
SBS/APP modified asphalt sheets
Roofing underlayments
Sound insulation and protective layers in building systems
