Simply roll out WarmFilm mats on a suitable underlayment, cover with a moisture barrier, lay the floor and connect to the thermostat and power. If needed, the mats can be cut to length on site with household scissors. There are no heating wires to accidentally cut or short-circuit. No step-down transformers, on-site splice connections or special tools are required. Underlayment and moisture barriers are purchased separately.

worth the investment
I ordered the floor heating film and the oj microline udg-4999 therostat with class A GFCI 120-220 VAC 15a. for my newly re made kitchen to go under my new floating len. flooring The discription of the film is a little confusing on the web sight. I thought it was going to be like a 1/16 thick but it's actually only about .010 thick! No need to adjust your padding for this product. Very user friendly very well built. It has a marking about every inch that you can cut this film to make it shorter to fit any space that's like 3ft by something. If this works like its supposed to i am going to install it in my bathroom and bedroom. I have a gass log in my fireplace but i hardly use it because my living room will get all warm and turn the thermastate off and the rest of the house gets cold. So now here is a solution to that because every room has it's own thermestate. Looks like it is worth the investment!

    Bought two of these to warm a mid section of our den floor where we lay to watch tv. Installed under laminate during a flooring upgrade. Works great, took the cold floor to a comfy warm temp.
