Creating innovative products for adding convenience in homes and offices, as far as underfloor heating is concerned, has been the forte of Warm Up. It provides a smooth and seamlessly finished subfloor for soft covering such as carpet, vinyl, and linoleum. Its low heat resistance enables easy passage of heat through the floor finish for even distribution throughout the room. Extremely thin with only 7mm depth, it is easy to install in combination with an insulated underlay.

It works but...
It does what it says on the tin, but I'm not sure how this is better than a 6mm MDF sheet that you could get cut to size for free from your local DIY store for 1/4 the price with 1/2 the joins. What am I missing here?
