  1. Marmox Multibond 3

    Marmox Multibond Adhesive/ Sealant (Zero VOC) 300ml


    Creates a permanent waterproof barrier, for use with Marmox Thermoblock.  The only sealant available on the market that is completely VOC free.

    Marmox Multibond is a premium sealant-adhesive.  It is made in the UK using the latest environmentally friendly technology to create a 100% solvent free material with absolutely zero VOC’s.

    It is possibly the 'greenest' sealant-adhesive available having no hazardous, environmental or ecological impact.  Unlike other mastics, if it gets on your hands or even clothes it can be washed away with just water without leaving a mark.  Similarly it does not stain stone or ceramic tiling like conventional sealant-adhesives do.  Once Multibond sets it becomes incredibly strong and fully waterproof.

    Being completely solvent free, it is compatible with virtually all materials.  Marmox Multibond is the all-in-one super solution that replaces all your tubes of silicone, acrylic and PU.  It also has acoustic properties so it not only bonds acoustic boards to the floor but also reduces the transmission of impact sound.

    It is also ideal for sealing around shower trays and baths, around bathroom fittings, around kitchen fittings and furniture and also as a grab adhesive.  Because the material is made using a different technology to silicones, acrylics and MS-Polymers, there is no latent chemical process happening within the material that can cause it to discolour; Multibond cannot discolour - it will always stay brilliant white.

  2. Marmox Thermoblock 1

    Marmox Thermoblock, Load Bearing Thermal Insulation Block (Pack)

    Regular Price: £166.50

    Special Price £155.22

    A load-bearing thermal insulation block which eliminates the cold bridge at the wall/floor junction.  Thermoblock BBA

    Marmox Thermoblock is a highly insulating, load-bearing building block that replaces the bottom course of blocks or bricks in a wall to eliminate or significantly reduce the thermal bridge at the wall floor junction.  Made of a strong and rigid epoxy-concrete frame that is integrated with fire-resistant XPS that gives the outstanding thermal insulation providing y values of between 0.03 to 0.07W/mK. 

    Although Thermoblocks are lightweight they are extremely strong and stable having a mean compressive strength of 9.0N/mm2 so can be used in most walls.  Additionally, because they are impermeable to water they can be used in damp conditions without any deterioration in their insulating properties so, not only does Thermoblock reduce thermal bridging, but it also creates a moisture barrier.  


    • Mean compressive strength >9N
    • Thermally more effective than enhanced construction designs
    • Compatible with all block types, bricks and timber frames
    • Creates a permanent waterproof barrier


    • Eliminates cold bridging at the wall/floor junction.
    • Eliminates the cold bridge under parapets.
    • Assists in achieving CfSH levels 4, 5, 6 and Passivhaus.
