Can I install the UFH system without insulation? 

Technically yes - but we don’t recommend it! Insulation material performs three important functions. 

• It prevents the downward flow of heat and saves its cost many times over in reducing the power needed for a room to reach the required temperature.

• It reduces the heat up times as it directs the heat generated up into the room in which it is laid.

• It helps to protect the mats themselves from damage by screw heads, nails or staples sticking up through the floor surface.

 Please bear in mind that users will invalidate their warranty if installing the system without suitable insulation material.
