Product description
UD glass fabric 649 g/m2 is a unidirectional high quality glass fibre fabric which is used for building boats, surfboards, longboards, skis and similar applications. The laminated thickness of this glass fabric is 0.4 mm and consumption is approximately 294 grams per square metre.
Unidirectional glass fabric is also available in a lighter version: UD Glass Fabric 400 gr/m2 (layer thickness: 0.51 mm).

Fabric or reinforcement type describes how the fibres are arranged. This affects how easily the material drapes over a shape and which directions it mainly reinforces.
- Plain weave (square weave): the yarns pass alternately over and under each other. The fabric is stable and works well on flat or gently curved surfaces.
- Twill weave: recognisable by its diagonal pattern. It is more flexible than plain weave and drapes more easily over curves.
- Unidirectional reinforcement (UD): the fibres run mainly in one direction, usually marked 0°. It provides reinforcement primarily along that direction.
- Multiaxial reinforcement: fibres are arranged in several directions, for example biaxial (+45°/-45°), Square (0°/90°) or triaxial (0°/+45°/-45°). Fibre bundles are normally held together by stitching rather than a conventional weave.
Note: a Square reinforcement (0°/90°) is not the same as a plain-woven square fabric. Also consider fibre type and areal weight (g/m²).

Areal weight is the weight of one square metre of dry reinforcement, expressed in g/m² (grams per square metre). For example, 200 g/m² glass fabric contains 200 grams of dry fibres per m², without resin. Areal weight helps with reinforcement selection and resin consumption estimates, but it is not the final laminate thickness.
