Description

A range of glass reinforced gypsum column casings designed to be plastered or rendered and painted on site after installation. The casings are solely for interior use. They are strong, quick and easy to install, and offer an alternative to pre-finished columns in a wide range of applications, including commercial buildings, hotels and retail interiors, in both new build and refurbishment situations where structural elements need to be decoratively concealed. GRG columns are a suitable option where a seamless casing is required, where no visible joints are seen. In addition to the standard ranges, bespoke items in almost any shape or size can be produced, with high levels of intricate detail. The casings are manufactured from alpha-calcium sulfate semi-hydrate (plaster) with glass fibre mat. Casings are mechanically fixed to timber battens fixed to existing columns. Joints and fixings can be concealed using a plaster mix on site.
