GRG is a medium strength composite material made from gypsum reinforced by fine fibres / strands of glass (gypsum is the base material of plaster).
Please click on the images below to see examples of GRG column casings which will give a flavour of what can be achieved. Alternatively please view our project gallery which showcases all column types.
This material is totally non-combustible and can be site finished with any interior quality paint.
Column casings are manufactured by applying layers of gypsum slurry and chopped strand glass fibres into a specially prepared mould to create custom architectural pieces.
As with many other composite materials (such as reinforced concrete), the two materials act together, each overcoming the deficits of the other. Whereas the gypsum (plaster) is strong in compressive loading and relatively weak in tensile strength, the glass fibres are very strong in tension but have low strength against compression. By combining the two materials together, GRG becomes a material that resists both compressive and tensile forces.
Key Advantages;
* Design flexibility - The material can be moulded into numerous shapes;
* Vast range of RAL colours available;
* Ideal for internal use with joints being filled and hidden;
* Non-combustible;
* Speed of manufacture.
* Low cost when compared to other cladding systems.
Key Disadvantages;
* Site filling and sanding of joints is a laborious operation;
* Site filling and sanding of joints is a relatively messy operation (wet trade);
* Paint finish applied after installation involving a second wet trade;
* Relatively low impact resistance compared to other forms of cladding.
