GRG: Glass Reinforced Gypsum

Glass Reinforced Gypsum (GRG) uses a combination of plaster, glass fibre matting/fibreglass chopped strands and metal/timber

Typically harder, stronger plasters are used so that larger items can be constructed without the excessive weight of traditional fibrous plasterwork.

Benefits of usage

  • High strength and surface hardness
  • Excellent reproduction of fine detail
  • Low expansion ensures dimensional accuracy avoiding cracking and breakage
  • Whiteness
