Lasting Elegance & Surprising Economy

Lasting EleganceThe growth of interest in ornamental plaster decoration is driven by a renewed appreciation for the functionality of this material. Ornamental plaster is lightweight, easily formed and can be engineered to produce massive profiles in long continuous lengths. It can be made to accept details and undercuts unmatched for depth and sharpness or to follow any curve or radius. By reinforcing cast plaster with fiberglass (called glass reinforced gypsum or "GRG"), steel or other materials, large, precisely formed units can be produced for quick installation. Ornamental plaster no longer needs to be fabricated in place with the attendant high labor costs, mess and down time required for fabrication and complete curing.

In short, ornamental plaster mouldings are still the designer's material of choice for defining wall openings and transitions between wall and ceiling, just as they have been for millenia. An extremely expressive material, moulded decorative work allows the interior designer unique control over the mood and impression of the space. It will accept most finishes, llcluding paints, foils and leaf. It will neither shrink, warp, burn nor produce toxic fumes. Truly, we have found nothing to surpass this versatile building material for safety, stability, economy, historical authenticity or beauty.
