Welding blanket and hot-work protection
For a welding blanket or protective curtain, describe whether the exposure is sparks, intermittent spatter or molten slag, and whether the fabric is vertical or horizontal. The substrate, coating level and finished build all affect how the fabric handles the duty.
- 430 / 660 / 840 g/m² base-fabric weights are starting points for discussion, not finished-product specifications.
- Confirm single-side or double-side coating by identifying which faces are exposed.
- For repeated heavy slag or molten-metal exposure, assess alternative constructions such as vermiculite-treated fabric or high silica rather than assuming silicone alone is suitable.
Expansion joint
An expansion joint is a multilayer system exposed to movement and often pressure or sealing requirements. A 660 / 840 / 1000 g/m² base-cloth discussion can help define a starting point, but a complete joint design needs the system build and operating conditions.
- Confirm movement, pressure, media, temperature and the required air or gas sealing.
- Double-side coating may be considered where both faces are exposed or where the design calls for it.
- Review the complete multilayer assembly and its test requirements.
Removable insulation jacket
For a removable insulation jacket, make sewing, folding, repeated installation and the feel of the exposed surface part of the selection. A silicone-coated fiberglass cover fabric may be evaluated when its construction suits the working environment.
- Specify a soft or flexible finish only after checking the sample by hand and through sewing trials.
- Select color from an approved sample.
- Confirm cleaning, oil, moisture and outdoor exposure requirements.
Smoke curtain
Smoke curtain specifications depend on the project code and required fire, smoke and mechanical tests. PU, acrylic and silicone coated fabrics may be assessed, but chemistry alone does not establish compliance.
- Name the exact target standard, edition and test method.
- Check that the submitted evidence covers the proposed fabric construction and intended assembly.
- Do not infer certification from a material description.

Frequently asked questions
Does a higher finished weight always mean better performance?
No. Finished weight combines the base fabric and coating and does not describe every relevant property. Compare weave, coating sides and level, thickness, flexibility, surface and test results for the full construction.
Does silicone-coated fiberglass have one working-temperature rating?
Suitability depends on the substrate, coating formulation, exposure duration, heat mode, mechanical load and atmosphere. Confirm the proposed construction against the required conditions and test method.
Can VETEX recommend a starting construction from an application description?
Yes. Share the use, exposure, dimensions, existing specification and test requirement. Any recommendation remains subject to sample and specification approval.
