Polyester Nonwoven for Construction & Roofing — PET Geotextile Membrane India
Polyester nonwoven for construction and roofing — Favourite Fab supplies PET spunbond and needle-punched polyester nonwoven in 80–600 GSM for breathable roofing underlayment, bituminous membrane reinforcement, building drainage, and waterproofing composites. PET delivers inherent UV resistance and 200°C continuous service temperature — properties PP-based construction fabrics cannot match for long-life exterior applications.
What Is Polyester Construction Nonwoven
Polyester construction nonwoven is PET fibre fabric engineered for civil and building applications: roof underlayment, breathable building membrane, geotextile drainage, and bituminous membrane carrier. The PET polymer provides UV resistance without additives (critical for outdoor service), high tensile strength for handling and installation, and chemical resistance against bitumen, asphalt, and construction chemicals.
Common applications in Indian construction: breathable roofing underlayment under tile, metal-sheet, or shingle roofs (replaces older bitumen felts); reinforcement carrier in modified bitumen waterproofing membranes (APP/SBS); geocomposite drainage layers in basement, retaining-wall, and green-roof drainage; vapour-permeable wall membrane for energy-efficient construction.
Polyester Nonwoven for Construction — Specs
| Application | Recommended GSM | Tensile | Key Property |
|---|---|---|---|
| Breathable roofing underlayment | 100–180 GSM | 300–500 N/5cm | UV stable, Sd-value <0.3 m |
| Bituminous membrane reinforcement | 120–220 GSM | 500–900 N/5cm | Bitumen penetration retention |
| Geocomposite drainage layer | 100–200 GSM | 400–800 N/5cm | Permittivity, hydraulic conductivity |
| Vapour-permeable wall membrane | 80–140 GSM | 250–450 N/5cm | Vapour permeability, tear resist |
| Green roof drainage | 150–300 GSM | 600–1,200 N/5cm | Long-term filtration, root resist |
| Basement drainage protection | 200–400 GSM | 800–1,500 N/5cm | CBR puncture, soil filter |
Why PET Nonwoven for Roofing — vs Bitumen Felt
Traditional bitumen felts have been replaced in modern construction by PET nonwoven underlayments. Key reasons: PET is lighter (40 g/m² vs 1,200 g/m²) reducing roof load; PET is breathable (Sd-value <0.3 m) preventing condensation; PET handles UV exposure during installation without degradation; PET tear strength outperforms bitumen felt during high-wind exposure before final roof covering installation.
Applications
- Roofing underlayment: 100–180 GSM PET spunbond as secondary water barrier under clay tile, concrete tile, metal sheet, or asphalt shingle roofs. Sd-value below 0.3 m for vapour permeability. UV-stable for 6+ months exposure during construction.
- Bituminous waterproofing carrier: 120–220 GSM PET spunbond reinforces APP/SBS-modified bitumen membranes. PET retains tensile strength after bitumen penetration at 180°C application temperatures.
- Building drainage geocomposite: 100–200 GSM PET nonwoven wrapped around 3D drainage core for basement, retaining wall, and green roof drainage. Soil filter + water transmission.
- Vapour control + breathable membrane: 80–140 GSM PET microporous laminate for energy-efficient building envelope (Passivhaus, LEED).
- Geotextile under hardscape: 200–400 GSM PET needle-punch for paver and pedestal-paver bases preventing soil contamination of crushed stone bed.

Frequently Asked Questions
What GSM polyester nonwoven is used for roofing underlayment?
Breathable roofing underlayment typically uses 100–180 GSM PET spunbond with Sd-value below 0.3 m for vapour permeability. Heavy-duty underlayment for metal sheet roofs may use 140–180 GSM for tear resistance during installation.
Can polyester nonwoven handle 180°C bitumen application?
Yes. PET fibre is dimensionally stable at 180°C continuous — sufficient margin for hot APP/SBS bitumen application temperatures. Tensile strength is retained after bitumen penetration. Specify “bitumen-compatible” grade when ordering for waterproofing membrane production.
What is the UV stability of polyester construction nonwoven?
PET fibre is inherently UV-stable — no UV stabiliser additives required. Outdoor service life exceeds 5 years for tensile-critical applications. For temporary roofing exposure during construction (6–12 months), no degradation in mechanical properties.
What MOQ does Favourite Fab require?
MOQ 1,000 kg per grade and GSM. Sample rolls (5–10 m) for qualification trials dispatched in 3–5 working days. Container-load pricing for 40ft HC orders for high-volume construction product manufacturers.
Does Favourite Fab supply geocomposite drainage fabric?
Yes. 100–200 GSM PET nonwoven supplied as filter wrap for 3D drainage core composites. Soil retention (AOS 0.075–0.15 mm) + water transmission capacity matched to project drainage requirements. Used in basement drainage, retaining wall drainage, and green roof systems.
