Chimney Build and Design

Grate Expectations use the PROMAFOUR® system for chimney lining installations on cassette and inset fireplaces, as well as wood-burning stoves. Versatile enough for use in building false chimney breasts or lining existing chimneys, PROMAFOUR® insulation boards are strong, reliable and able to withstand continuous high temperatures.

When purchasing a fireplace our design team will be able to provide visuals and drawings so that you achieve the design and meet all safety requirements. We have detailed some of the core elements of Chimney Build & Design below and there is also a PROMAFOUR® brochure available for review if you require further information.

Chimney Build & Design

PROMAFOUR® boards are cement bonded calcium silicate based insulation boards. These large-sized multi-purpose boards are easy to handle and offer a superior combination of enhanced technical properties for building strong, mechanically self-supporting constructions.

PROMAFOUR® Boards form part of the PROMAFOUR® fireplace insulation system used to build a false chimney breast for a cassette/inset type fire place, or line existing chimney breast against concrete or timber frame.

The PROMAFOUR® System is a safe reliable, robust system developed to resist continuous high temperatures of up to 1000°C.
