Dome
Glass reinforced gypsum (GRG)
GRG uses a combination of plaster,glass fibre matting/fibre glass 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 plaster work
This is high strength and surface hardness,excellent reproduction of fine detail,low expansion ensures dimensional accuracy avoiding cracking and breakage,and whiteness
