Isulation Under Laminate Floor on a Concrete Slab

brad257

Hello,

I have laminate floor laid in my lounge/dinning room and it was put and unfinished before I moved in. It has a very thin foam/foil underlay. I am finding that the heat loss through the floor is extensive to the fact that radiators are struggling to keep up the temperature required.

I would like some options for insulating the concrete slab without creating a raised floor

I am planning on taking up the laminate flooring and relaying it

Underlays or tiles, I have searched online but am struggling to find my best option

Thanks in advance

Not sure if this helps or not but have a look here:

Whatever underlay you put under needs for form a firm surface..it's it's too thick or too spongy underfoot then it will put additional strain on the joins and may pop apart.
I'm not convinced that the your main heat losses are through the floor though..it may feel cold but i'm doubtful your losing much heat downwards. I'd be first checking for draughts around windows, fit cavity wall insulation, topping up loft insulation as necessary, heavy lined curtains, radiator reflector foil panels on external walls etc etc.
Could also be that the radiators are insufficiently sized for the room..or even just need bleeding of air or not working at their optimum if sludged up etc.

Hope that helps

Thanks for the quick reply all of the above you mentioned are currently in the works, the radiators are being re-sized in the new year, its just I have laminate flooring (already laid when I moved in) in the hallway, again on a concrete slab, and the heat difference is very noticeable the hallway being actually warm as opposed to uncomfortably cold for bare feet as that of the living/dinning room.

Hi There, our company does a product called Rockfloor which sounds like it may help, take a look at ttp://guide.rockwool.co.uk/building-elements/floor-/ground-floors.aspx?page=3255 (add a "h" at the start), it mentions in the text that adding above the concrete floor helps the room to respond more quickly to the heating system. Hope that this helps.
