My dining room is underheated, and with laminate flooring always seems to have a cold floor.
As I have a deep underfloor void I can access the floor from below, so I was wondering if it'd be worth putting in some diy underfloor heating. I'm thinking of screwing some thin metal diffuser plates to the underside of the floorboards, some microbore CH pipe onto that then filling the inter-joist spaces with standard loft insulation (plus a few batons to hold it in place.)
A couple of things I'm not sure about: I don't know the insulating properties of the cushioning under the laminate (it's only 2-3mm thick), nor any idea of actual heat transfer with such a setup.
I wonder if it would be worth it?
(As for the cold floor - I don't want to cover the laminate with rugs, or replace it with carpet because the room is actually a main thoroughfare through the house... the reason for putting laminate there in the first place.)
