The Ten Parameters to Confirm Before Quoting Coated Fiberglass Fabric
Why we ask ten questions before quoting — and what goes wrong when a buyer answers only "price per meter". A short guide to faster, dispute-free quotations.
A quotation for coated fiberglass fabric is only as good as the specification behind it. When we receive only "price per meter", either we guess — or we ask. These are the ten parameters we confirm first, and why each one changes the number.
Quick Answer
Application, base fabric, finished weight, thickness, coating type, single or double side, width, roll length, color, and required standard or test. Ten answers in the first email cut quotation time from days to hours.
1–3: Application, Base Fabric, Finished Weight
Application decides everything downstream — a welding blanket, an expansion joint and an insulation jacket each pull the specification in different directions. Base fabric (for example E-glass style 3732 at 430 g/m², or style 3788 at 1650 g/m²) sets the mechanical skeleton. Finished weight, coating included, fixes both performance and cost.
4–6: Thickness, Coating Type, Coating Side
Thickness (0.2–2.0 mm for silicone coated fabric) affects drape and insulation. Coating type — silicone, PU, acrylic or vermiculite — follows the duty: silicone for gas-tightness and weather, PU and acrylic for economical protection, vermiculite where molten metal splash lands. Single or double side decides whether both faces resist the media.
7–10: Width, Roll Length, Color, Standard
Width (1000–2000 mm, or custom) changes cutting yield on your sewing lines. Roll length (50 or 100 m typical for laminated fabric) changes freight and handling. Color matters for finished products and site visibility. The required standard or test report — EN 1869, UL 94 or project-specific — must be named before production, not after.
Why This Protects the Buyer
Every dispute we have seen traces back to an unspecified parameter: coating weight assumed instead of stated, width measured differently at both ends, a standard required after delivery. Ten answers up front make the quotation comparable across suppliers — and make the delivered roll match the expectation.
