London's Thermal Insulation Specialists

Working across London, we specialise in providing first class and affordable thermal insulation products, especially helpful for eliminating the cold bridge and floor and wall junctions.  

The high quality equipment and materials we use are designed to be placed at the base of a timber-frame or masonry wall to address the thermal bridge. Alongside this, the mean compressive strength of 9N/mm2 allows for our thermal insulation products to be used under most load-bearing walls.  

In addition, because our thermal insulation products are impermeable to water, they are also suitable for use in damp conditions without any risk of losing their insulation properties. So not only do our products reduce thermal bridging, they also create an effective moisture barrier in London properties too.  

Call London's experts at Marmox today on 01634 835290 or leave us a message on our contact page to learn more about our Thermoblock thermal insulation products, as well as our range of sound absorptions products and waterproofing products available for clients across London and the South East.

Guaranteed Compliance to Building Regulations

Our thermal insulation products meet all UK and Ireland building regulations. The current regulations state that 'the building fabric should be continuous over the whole building envelope and constructed so that there are no reasonably avoidable thermal bridges in the insulation layers caused by gaps in the various elements'. The high quality and affordable thermal insulation equipment we use satisfies this requirement perfectly by connecting the wall insulation with the floor insulation.  

The BBA certified Thermoblock was designed and created to provide an effective, affordable and easy solution to the problem of thermal bridging. One junction of major concern has been where the floor meets the wall (timber frame OR masonry) but using Marmox Thermoblock will guarantee compliance with current regulations and also with proposed zero carbon regulations.
