PROMAFOUR, the ideal insulation and mantelpiece for your fireplace

A fire or stove represents an important added value to your house. Not only does it create a good atmosphere and a lot of cosiness, it also happens to be an excellent choice with regard to rational energy consumption.

The key advantages of the PROMAFOUR system

Safe & reliable

PROMAFOUR construction boards are non-combustible and continuously resist to very high temperatures up to 1000°C. They don’t contain any bonding agent, which could emit an irritating odour or affect the cohesion of the board in a negative way.

Aesthetics and comfort

PROMAFOUR construction boards have a naturally smooth surface which is ideal for painting without additional plastering. Thanks to minimal expansion and contraction during and after heating, the risk of cracks, microscopic fissures or deformation is reduced to an absolute minimum.

By insulating your fireplace floor and rear wall with PROMASIL-1000L board, the loss of heat is reduced to bare minimum. Thanks to the high storage thermal capacity of PROMAFOUR construction boards, the emitted heat is distributed in your living room. Your fireplace will emit heat even after the fire is extinguished.

Mechanical strength and solidity

PROMAFOUR construction boards are composed of calcium silicate and cement. This results in very strong walls, even with minimal thicknesses of 12mm, 15mm or 18mm. Also heavier objects can be attached to the wall without additional strengthening.

Quick and easy installation

PROMAFOUR construction boards can be easily cut with traditional woodworking equipment and installed using standard screws, staples and refractory PROMAFOUR-GLUE 1000.

The PROMAFOUR system is mounted in 4 steps

1. Rear wall and floor insulation with PROMASIL-1000L.

2. Frame composed of metal U-profiles and PROMAFOUR STUDS.

3. Casing composed of PROMAFOUR construction boards.

4. Finish joints and corners with PROMAFOUR-HT JOINTFILLER and PROMAFOUR-PRIMER before painting.
