"Any comments on this product? "

I highly recommend this product I have good experience with it from customer all over, excellent product easy to install, and great feeling walking on warm floor.

"Will it give me any heat in this room?"

More NO then yes, any heat in any room will help reduce the cooling in that room, but that product not meant to warm the room, in some condition it will warm more then in others.

"Do I need the cork insulation between it and the concrete floor? "

No you donÂt have to, but you can use insulation if you want.
Example on how to install it in cement slab, like this. Slab, Cork, Mortar bed, heating system, latex Portland cement, then install the tile with thinset

Check this link to see all the option you have with insulation, slab, framing this will get you the idea on how to install it

Here is a link that might be useful: all abut suntouch

Actually, the concrete itself acts as an insulator. The cork would be a waste of money.

I agree, though, that this is not meant as a primary heat source. it'll help, but it won't warm up the room, per se.

I decided to put in Suntouch after reading all the great comments on this website. We live in Dallas and the nights are cold. I went to Lowes and bought the mats there but my question is are all the Suntouch products the same? The big box stores were the only places that had the 30" width. On the website and other places all the widths were either 12" or 24" or 36". Are the mats sold at Lowes a lesser quality with the reduced price? Also my tile guy said it will add height to the floor and I should have made my vanity taller to compensate. Love hearing from all the experts.

The quality of what you buy at the big box stores will be the same as what you buy from a tile showroom or on line.

How much height does it add? Can you put it in a porch area only and continue with your tile without the floor heat?

The overall thickness of your completed SunTouch from the top of your slab should be abut 3/8" plus the thickens of your tile,
Yes you can use the heating for a specific area even a small portion of a room, like the side of bed, around the dinning room table or in front of your sink in your kitchen, a tile installer will know how to level the floors so you will not see the heights different
Bill is right as the concrete act as insulation, but on other hand concrete slabs will "drain" some of the heat from your floor. So, a good idea is to attach a layer of cork or other insulating material to the concrete first, then attach the mat.
As I mention before it is optional and you do not have to install cork.
In regard to sizes availability, you always have the option of WarmWire, it sold cheaper then the mat, and you set the size you need where ever you need.

One thing you need to realise, though-- if you use the cork underlayment as an insulation, you have no choice in the matter-- you MUST use epoxy grout. Any other grout will crack.

hi there
we have suntouch in part of our kitchen under 12 inch porcelain tile. this portion of the kitchen is over an (ancient) concrete slab that used to be the back porch. we installed it ourselves (bought it at HD). it was not that hard...we converted our skeptic friend that thought it would never with our DIY tiling. i worried about the concrete sucking the heat out but decided i didn't care...and i am not good enough at tiling to have anything i don't understand (cork) underneath the tile. we were cheap and didn't buy enough to cover every last inch of the mudroom...now the nice warm part makes the regular part feel like you're standing on an ice cube. do the whole floor!! also, we do not have any other heat in our kitchen...suntouch doesn't heat the room, but it does allow us to work in the room comfortably because our feet are toasty...that's usually the first part to get cold. good luck kren ps for a DIY, i thought the mat really helped...i wouldn't have worked with wires alone.
