Marmox FireBoard
€23,00
NEW Marmox Fireboard provides A1 fire resistance and both acoustic & thermal insulation in a lightweight board.
These External Wall Insulation (EWI) boards are designed for use with masonry, timber and steel frame constructions, offering fireproofing and insulation to walls and ceilings, both internally and externally.
Not only fire protection, Marmox Fireboard is also 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.
