Fyberglaze GRP – Glass Reinforced Plastic

Fyberglaze or Fybaglaze is a high quality anti-vandal glazing material resembling Georgian wired cast glass. Manufactured by combining millions of small fibres or glass rods with specialised thermoset resins and curing agents to create an immensely strong composite product.

Finishing & Fabrication Available

  • Saw Cutting
See options below


Security glazing for rooflights, balcony panels and areas where Georgian wired cast is being continually broken. Vacant property, bus shelters, schools, fire doors, stairwells.


  • Easy graffiti removal
  • Versatile
  • Can be manufactured to size
  • Easy to clean
  • Available in embossed and smooth

Fire Resistance Products can be manufactured to either:

  1. General purpose (GP) grade (all products)
  2. BS 476 Part 7 Class 1 (all products)
  3. BS 476 Part 6 Class ‘O’ (all products)
  4. BS 476 Part 7 Class 2 (all products)
  5. BS 476 Part 22 ½ hour fire rating (Fybagard to Class 1/0 only)
Thermal Co-Efficient Of Expansion 30 x 10^(-6) / °C
FACT: Compared with many other plastics GRP has minimal expansion and contraction
characteristics and will not bow and warp in extremes of temperature.
Thermal Conductivity 0.2w/mK
FACT: Significantly lower than glass.
Impact Resistance To BS 5544 (cert no: 395-1) and regulation 14 compliant.
FACT: Steel Ball drop test concluded no penetration or breakage of GRP glazing.
Uv / Light Transmission Up to 83% depending on thickness and surface texture.
FACT: The inclusion of our unique surface protection membrane can significantly enhance the quality, appearance
and lifespan of GRP Glazing by providing a high level of UV resistance, thus ensuring continued light transmission.
Graffiti Resistance A factory applied coating operation ensures simple removal of graffiti with no detrimental surface effects to the panel.
Flexural Strength 170 MPa
FACT: Will not bow or flex as much as other glazing plastics.
Tensile Strength 100 MPa
FACT: GRP sheet is up to seven times stronger than mild steel on a weight for weight basis.
Tensile Modulus 8 GPa
Sheet Dimensions Fybagard / Fybalyte:
Standard stock sheet size is 8 x 4 (2440mm x 1220mm), but as all panels are manufactured
to customer requirements, virtually any length can be accommodated (bearing in mind
manhandling and delivery issues maximum length is generally 3500mm) – there is a width
restriction of 1525mm.Fybamesh:
8 x 4 (2440mm x 1220mm) or any derivative within these sizes.
Sheet Strength Standard product range can be manufactured to literally any thickness with 3mm, 4mm & 6mm being standard.
12mm is usually maximum thickness produced.
Cutting And Handling Fybagard / Fybalyte:
Jig saw, Bench saw (using diamond tipped blade) or Guillotine.Fybamesh:
Guillotine abrasive disc, Jig saw (using metal cutting blades). Cut in well-ventilated area using gloves,
eye protection and dust particle masks.

Due to the wide variety of products within this range these technical specifications should be considered as a guide only.
