XPS insulation boards are designed specifically for use with electric underfloor heating systems, very high compressive strength (30 tonnes / m2), light weight, high efficiency and low cost make this thermal board an ideal choice when fitting heating on to a poorly insulated concrete or screed base and works excellently with underfloor heating underwood and under tile systems. Insulation boards come with 50 year warranty.




The dimensions of each board are 0.72m2 (20mm x 1200mm x 600mm)


How many boards do you need to cover your room?

 Room length (metres), multiple by room width (metres) = total room size in square metres

 Take room square metres and divide by 0.72 (square metre of insulation board) = number of boards required.


See example below;

Room length - 10 metres

Room width - 10 metres

Total room square metre size = 100 square metres

100 / 0.72 = 139 insulation boards required

Always add an additional 2 - 5 boards when ordering, to ensure all floor space is covered.
