Insulation

warm up concrete floor in bedroom

Anonymous user 28/02/2024 - 3.08 PM

Hi there I've just bought a house and the upstairs box room has a concrete floor( built above the garage). What I would like to do is make this floor alot warmer and put carpet on it (prev had cheap laminate flooring). In my mind I would like to put 150mm celotex XR4150 followed by 2 part self levelling compound and then underlay and carpet. Is this the right way to do this? How do i fix the celotex to the concrete floor? any help would be appreciated. thanks SC --- hi Peter- how does the celotex get fitted onto the concrete floor? stixall adeshive or screws? thanks

Hi, your best way forward is to lay a floating floor. Basically you put the celotex on top of the concrete then a 22mm tongue & groove chipboard floor ( as used in most house construction ) on top of the celotex. You can then carpet over the chipboard flooring. The celotex can be put directly onto the concrete, no fixing adhesive is required. You could also add a layer of 1000gauge polythene between the concrete and celotex, dressed up the wall the thickness of the insulation (150mm), around the perimiter of the room. This will add a damp proof / condensation barrier. Peter
