Insulation under laminate for concrete floors,
Discussion
My 80's (cavity wall, loft insulated, double glazed) house has concrete floors throughout downstairs with Karndean laid on it everywhere.
The floor is always cold, even with the heating on all day and lounge gas fire going you can feel the floor sucking the heat up. I've always lived in houses with suspended floors before and it doesn't feel like this.
My neighbour has underfloor heating and thats lovely, but we can't run to that for this house.
Whats the best insulation to put down before a new laminate is laid? (I want to keep a practical hard floor throughout).
I thought about kingspan, but then the the first step up the stairs would end up weirdly small....
Is there a 10mm product out there - what have people had good experience with?
Any negatives from doing this e.g. the slab won't ever "heat up" - but it never feels like it ever has......

We have solid concrete floors through the bottom of our house, with engineered oak flooring on top. One half has insulation under the screed, the other hasn't. Really not sure I can notice the temperature difference between them.
We have this underneath, floor never feels cold. http://www.tradepriced.co.uk/tredaire_boardwalk_la...
Gaps under skirting edge can cause draughts, silicone sealant could help.

Nice warm underlay and carpet are the best fix! And take your shoes off at the front door.
Of course! but not for us.I'm leaning towards this type of underlay - claims to have the best insulation, although it seems to be like cheapo stuff: http://www.tradepriced.co.uk/techni-board_underlay...
Seems Pergo allow installation on polystyrene: http://www.pergo.co.uk/en-GB/why-choose-pergo-lami...
Probably get a Quick Step laminate. Skirtings will come off for a clean install.

I put 10mm XPS under my engineered wood floor although you can get it in 5mm. It's been down a couple of years now with no issues. It's enough to make the floor really warm to walk on even in the coldest of winters. I'll try and find a few pics....
This is the route we are going down, but at 22mm thick with UFH. You can get it in basic sheet form as well. We are getting all of ours from "the under floor heating store" though they can pricey.
Hmmm maybe XPS is a better choice.
Has anyone laid laminate flooring direct to XPS without a t&g layer?
Pergo say you can if the polystyrene has a minimum compressive strength of 250 kPa.
This 10mm XPS: http://www.ambient-elec.co.uk/buy/blueboard-insula... is 30 tonnes / m2 = 294kpa
