Thermal Co-Efficient of Expansion

30 x 10­^(-6) /Deg C
Note: Compared with many other plastics GRP has minimal expansion and contraction characteristics and will not bow and warp in extremes of temperature.

Thermal Conductivity

Fybatex: 0.2 w/mK
Fybacore: The thermal conductivity is entirely dependent on the chosen substrate, but better than 0.35 “U” value is achievable.

Colour Range

Panels can be manufactured to the following:

  1. B.S. 4800 Colour Range
  2. B.S. 5252 Colour Range
  3. RAL Colour Range

A colour match service is also available.

Flexural Strength

193 MPa
Note: Flexural strength can be enhanced by the addition of woven reinforcement if required.

Tensile Strength


Tensile Modulus

7.1 GPa
Note: GRP sheet is up to seven times stronger than mild steel on a weight for weight basis.

Size & Thickness

Panels can be manufactured to any length but with a width restriction of 1525mm. Standard product range can be manufactured in thicknesses from 3mm upwards.
