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!
