Marmox Fireboard Acoustic Thermal Insulation Board is a board that combines Marmox stone wool with a fibreglass mesh/cement based coating on both sides, that can be rendered or plastered over. Marmox stone wool is resistant to combustion and its mass of fibres and air interrupts sound waves from reaching a solid material.

Marmox Fireboard  is available in 3 board sizes/thicknesses:

• 11200 x 600 x 20mm
• 1200 x 600 x 50mm
• 1200 x 600 x 100mm

Marmox Fireboard offers A1 fire resistance and both acoustic & thermal insulation in a lightweight board. It is designed for use with masonry, timber and steel frame constructions, and offers fireproofing and insulation benefits for walls and ceilings, both internally and externally.

Marmox Fireboard is not limited to only fire protection, it also can be used as a weather proof barrier which will not degrade, however wet it gets! Also, being made from mineral wool, the boards provide very good sound decoupling and sound absorption properties. Ideal for using on ceilings in apartments to help block sound from neighbours.

Applications:

• Use Marmox Fireboard to fireproof any metal, masonry or wooden structures.
• Use as a fireproof alternative to plasterboard on internal walls and ceilings where fire protection and sound proofing is required. Apply a finish coat of plaster.
• Use on fire surround walls.
• Use for window and door reveals, where thin fireproof boards are required.
• Use to reduce thermal bridging on up-stands, used as a non-combustible inverted roof up-stand insulation board.

Fire Classification:
Certified A1 non-combustible. Marmox Fireboard meets the stringent requirements, as defined in the Euroclass system (BS EN 1350-1).

Acoustic Properties:
Stone wool-based products are one of the most popular sound absorption materials. Sound-waves travel fastest through solid objects! However, if an air gap is placed in the path of a sound-wave it will not have the necessary medium to pass through. Being a mass of fibres and air, Fireboards provide the needed interruption to sound-waves.
