The original Marmox Multiboards are a time tested, multipurpose solution for waterproofing, insulating & drylining.
What are Multiboards made from?
Marmox Multiboards are made using extruded polystyrene, coated either side with fibreglass mesh which is embedded in a cement polymer mortar. Available in sheet sizes of 600mm x 1250mm or 600mm x 2500mm. Thicknesses are 4, 6, 10, 12.5, 20, 30, 40, 50, 60mm.
One of the most popular wetroom / tilebacker boards on the market, Marmox Multiboards can be used to coat floors, walls and ceilings in order to offer a full tanking solution. Being made from extruded polystyrene, which is a closed cell material, means that no water is able to penetrate Multiboards. They are totally waterproof!
BBA approved, Marmox Multiboards have a unique patented honeycomb surface finish which allows for ultra-strong adhesion and a pull of strength in excess of 100kg/m2, which is up to 5 times that of standard plasterboard. They importantly provide an effective decoupling membrane to prevent tiles and grout from cracking due to any horizontal movement in the floor.
Insulation and drylining
Marmox Multiboards are a brilliant insulator and offer R Values from 0.11 – 1.67, depending on thickness, with a thermal conductivity of 0.034 Watts/mK.
Of course, Marmox Multiboards are not only for use with tiles. The boards are commonly used in many areas of a building, to line walls, floors and ceilings which may be in need of insulation. Simply run some Marmox mesh tape over the joints and they are ready to receive a coat of plaster. No special treatment needed. Just plaster directly onto them.
Underfloor heating systems
One of the most popular ways Multiboards are used as an insulator is with underfloor heating systems. 40% of heat that is generated by underfloor heating gets lost through a concrete floor, so insulating well is very important. Multiboards reflect heat upwards into the room which significantly reduces that heat loss and therefore, when using Multiboards in conjunction with an underfloor heating system, a warm floor surface can be achieved in just 20 minutes, as opposed to several hours if not used. Even the thinnest 4 and 6mm Multiboards will offer some insulation, although real noticeable heat saving starts at 10mm. Marmox Multiboards can support a weight of 40 tonnes/m2.
Marmox Multiboards offer a full wetroom solution, this means that they can also be used to construct partition walls, bath surrounds, benches, vanity units, pipe boxing, steps and even curved shapes. With Marmox MSP360 adhesive and Marmox Corkscrew fixings it’s easy to construct just about anything your imagination with allow. Then just add tiles or plaster!
Marmox Multiboards are certified for external use and therefore can be used as an external tilebacker board and also beneath a coat of render.
