Marmox Multiboards are Multi-Purpose construction boards which can be used for waterproofing, insulating or constructing. 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.
It’s a construction board
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. Multiboards are available in many thicknesses from 4mm to 60mm and when used with Marmox MSP360 adhesive and Marmox Corkscrew fixings it’s easy to construct just about anything your imagination with allow. Then simply add tiles or plaster!
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.
External Use
Marmox Multiboards are certified for external use and therefore can be used as an external tilebacker board and also beneath a coat of render.
What are Multiboards made from?
Marmox Multiboards are made using extruded polystyrene, coated either side with fibreglass mesh and then embedded in Marmox cement polymer mortar. Available in sheet sizes of 600mmx1250mm or 600mmx2500mm. Thicknesses are 4, 6, 10, 12.5, 20, 30, 40, 50, 60mm.
