We are currently involved with some big projects with Stonewood Builders, building many fireplaces out of a fireproof board known as Promafour, fitting high end wood burners and installing stone surrounds.
Promafour boards are an excellent building product for fireplaces as they are strong, robust and have great thermal properties. It's an exceptional board that is A1 rated against heat and fire and is also a Hetas approved product.
We have been installing stone surrounds and wood burners to their masonry fireplaces and parging their existing inglenook fireplace.
