Underfloor Heating


Alongside offering our clients a Liquid Screed product, we are also a underfloor heating manufacturer, manufacturing wet underfloor heating for all types of applications, such as new builds, rennovations, victorian houses, barn conversions and conservatories as well as different types of commercial properties, from castles, to leisure centres. Our company, Max4therm, plans, designs and installs all of the underfloor heating systems. With Max4therm underfloor heating, you can lay tiles, stone, wooden flooring and carpets with ease.

Underfloor heating is an extremely efficient way of heating the property/premises, with a reduction in your fuel bills, between 30% and 40%; therefore having a reduced impact on the environment. Our Liquid Screed is perfect for pouring on top of underfloor heating. The total height of the screed with the underfloor heating can vary from as little as 15mm thick to 50mm thick, depending on what type of underfloor heating systems are laid. Our Max4therm underfloor heating systems are as low as 15mm in height, finished, ready for the floor finish to be laid on top. Up to 50% less screed is required with selected underfloor heating systems, for instance when the Max4therm underfloor heating system is fitted it's as little as 15mm high.

How Is Underfloor Heating and Screed Laid?

You start with your foundations and concrete sub floor. On top of this you lay insulation (to help prevent loss of heat), it's then sealed with a polythene film before underfloor heating can be laid. The underfloor heating is laid, our liquid screed is poured on top and after drying, it leaves a smooth level floor. You then select your final flooring, such as tiles, stone, wooden flooring or carpets and lay them straight on top within 24 to 28 hours.

Please note, that it is no longer recommended that a traditonal method such as 'sand and cement' is laid on top of underfloor heating. Technologies have moved on in recent years and our Liquid Screed gives improved thermal properties that the traditioanl method cannot compete with and therefore the traditional method, now has become almost extinct in underfloor heating applications because of it causes the homeowner to have increased running costs. This is due to liquid screed being a better heat conductor than the traditional sand and cement screed, as it doesn't have any air pockets, which acts as an insulator, rather than conducting the heat.
