SF FOIL SUNFLEX FLOOR REFLECTIVE FOIL

Description

Reflective foil under floor heating

In the case of underfloor heating, the heat is conducted not only towards the heated space, but also in the opposite direction, into the floor. SUNFLEX Floor Plus underlay foil for floor heating reduces heating of the area below the heat-conducting pipes and reflects the heat  back into the living space. The foil improves transversal conduction of heat upwards and sideways thus enabling a uniform temperature of the floor. It can be used as an expansion pad when it is rolled up in the corners towards the wall. SUNFLEX Floor Plus Foil can also be used for insulation of water and heating pipes or the insulation of air-conditioning, as well as the application of foil behind radiators.

Using foil SUNFLEX Floor Plus we increase the efficiency of the underfloor heating by up to 8% and reduce losses towards the floor by up to 18%.

Advantages of SUNFLEX Floor Plus foil:

Installation

Underlying SUNFLEX Floor Plus for floor heating is laid with the reflective side facing down on the polystyrene substrate between the reflective layer and the heating pipes. This will create an air gap that will support reflective effects. The foil can be easily cut with scissors to the desired size. It also serves as a separation barrier against leakage of the concrete layer between the insulation and formation of thermal bridges.
