Gypsum & GRG Cornices and Mouldings

A cornice finishes the junction between wall and ceiling. Beyond the decorative effect, it hides the uneven line where two trades meet — which is why it appears in almost every hospitality, retail and high-end residential interior.

We produce cornices in solid gypsum plaster and in GRG — glass fibre reinforced gypsum. Both are painted after installation and both hold fine relief; the difference is weight and the size of section that can be produced without reinforcement.

Gypsum Cornices

Cast in steel and fibreglass moulds from dense plaster. Detail holds sharply through the cast, and after jointing and painting the cornice reads as part of the structure rather than an applied strip. This is the material specified for hotels, heritage-style interiors and premium residential work.

Standard specification — custom values available on request.

Material	Gypsum plaster, high density
Standard lengths	2400 mm, 3000 mm
Profile sizes	From 60 mm to 300 mm face width
Profiles available	French, retro, European and contemporary designs
Finish	Unpainted, jointed and painted on site
Installation	Cornice adhesive, joints filled and sanded

GRG Cornices

GRG is gypsum with glass fibre reinforcement cast into it. The fibre carries the tensile load that plain plaster cannot, so a GRG section can be produced far thinner and lighter than the equivalent solid casting — and in lengths and profiles that would be impractical or unsafe in plain plaster. It paints and joints identically, so a GRG cornice and a plaster ornament finish as one surface.

Standard specification — custom values available on request.

Material	Glass fibre reinforced gypsum (GRG)
Standard lengths	2400 mm, 3000 mm
Profile sizes	From 60 mm to 400 mm face width
Weight	Substantially lighter than the equivalent solid plaster section
Finish	Unpainted, jointed and painted on site
Advantages	Lighter to handle overhead, stronger in thin sections, lower shipping weight

Choosing between them

Specify solid gypsum when	The profile is small to medium and the section is not weight-critical; the traditional solid feel is wanted
Specify GRG when	The section is large, deep or thin-walled; the cornice is long and has to be lifted overhead; shipping weight matters on container orders

Where they are used

• Hotels, resorts and serviced apartments
• Residential and apartment developments
• Retail stores and shopping centres
• Restaurants, cafés and function spaces
• Offices and corporate reception areas

Ordering

Send us the profile you need — a photograph, a drawing or a sample, plus the total linear metres. If you are matching an existing profile we can produce a new mould against your sample. Standard profiles ship from stock; new moulds typically take 15–25 days to develop and produce.
