Fiberglass mesh fabric Laid Scrims for reinforced Flexible Duct Air conditioning for Middle East Countries
Fiberglass mesh fabric Laid Scrims Brief Introduction
This product is a Fiberglass Laid Scrim, a high-performance reinforcement fabric engineered specifically as the load-carrying skeleton for flexible duct composites used in air conditioning and HVAC systems across Middle East markets. It is manufactured by chemically bonding continuous E-glass filament yarns into an open mesh construction (square or tri-directional), with binder options (PVOH, PVC, Acrylic, or customized) to match different aluminum foil / PE film / fiberglass cloth laminating processes. In a flexible duct, the scrim is sandwiched between the inner airtight layer and the outer protective jacket (commonly aluminum foil + PET + glass cloth stack) to become the "anti-collapse grid" that resists longitudinal stretching during installation, negative-pressure collapse during operation, and dimensional drift under the high heat, UV, and dust cycles typical of Gulf HVAC projects.
Fiberglass mesh fabric Laid Scrims Characteristics
ailored for Flexible Duct Composites: The glass scrim delivers a property set that matters to HVAC duct converters and contractors — high tenacity, dimensional stability, flexibility, low shrinkage, low elongation, alkali resistance, fire resistance, and corrosion resistance. E-glass being inherently non-combustible also supports the fire strategy of building HVAC systems where flexible ducts pass through fire-rated shafts or plenum spaces.
High Strength & Light Weight: Reinforcement comes at very low GSM so the duct stays light and collapsible-friendly. Regular duct-grade specs on this platform: CF12.5×12.5PH ~6.2–6.6 g/m², CF10×10PH ~8–9 g/m², CF6.25×6.25PH ~12–13.2 g/m², CF5×5PH ~15.2 g/m², with 12.5×6.25mm also available.
Long Rolls & Process Compatibility: Roll width 200–2,500 mm; roll length 10,000 m regular supply, platform capacity up to 50,000 m. Fewer splices per shift on high-speed foil/scrim laminating lines, higher yield, fewer weak spots in finished duct rolls. Yarn types extend beyond glass to Polyester, Carbon, Cotton, Flax, Jute, Viscose, Kevlar, Nomex; construction square or tri-directional; patterns 0.8–3 yarns/cm; binder matched to your laminating adhesive.

Fiberglass mesh fabric Laid Scrims Application
Primary Use: Reinforcement for Flexible Duct Composites (HVAC / Air Conditioning)
The core and specialized application of this fiberglass laid scrim is as the hidden tensile skeleton laminated into the wall of flexible air ducts — between aluminum foil / PET / PE layers and the outer glass-cloth or scrim-reinforced jacket — for residential, commercial, and light-industrial HVAC across Middle East markets ( villa projects, malls, hotels, district cooling distribution, etc.). It is sandwiched into the duct wall to:
Resist Installation Pull & Negative-Pressure Collapse
Flexible ducts are pulled through ceiling voids and connected under negative pressure from the AHU. The scrim's multi-directional tensile and low elongation prevent the duct from over-stretching when pulled, and from flattening/collapsing when the system runs — maintaining designed airflow and static pressure.
Survive Thermal & Dust Cycles in Gulf Environments
Rooftop units and exposed risers in the Middle East see >45 °C daytime, UV, and sand-laden air. The scrim's low shrinkage and dimensional stability keep the duct jacket from cupping, wrinkling, or tearing at staple/shield fixings as the assembly heats and cools.
Enable High-Speed Duct Lamination Throughput
Roll lengths up to 10,000 m (platform 50,000 m) feed high-speed foil-scrim laminators with fewer splice stops — directly relevant because flexible duct lines often run the same laminators as aluminum foil insulation (the company notes "over 80% of insulation aluminium foil factories in China" use Gadtex scrim, which shares the same line logic for duct-core foil).
Secondary Applications
Due to its versatile reinforcement properties and open mesh design, this fiberglass laid scrim is also extensively applied in other industrial sectors listed on the product page:
Aluminum Foil Composite
Roll lengths up to 10,000 m (platform 50,000 m) feed high-speed foil-scrim laminators with fewer splice stops — directly relevant because flexible duct lines often run the same laminators as aluminum foil insulation (the company notes "over 80% of insulation aluminium foil factories in China" use Gadtex scrim, which shares the same line logic for duct-core foil).
PVC Tarpaulin
Used as a base material to produce truck covers, light awnings, banners, and sail cloth.
