Insulating existing concrete floor uk.

Where concrete floor slabs have replaced earlier floors they may include a damp proof membrane dpm but unless laid comparatively recently they might not be well insulated. There will be a damp proof membrane under the insulation and possibly a second membrane on top depending on the type of screed. Converting existing unheated basements garages and storage areas into habitable rooms is a popular way of increasing living space without constructing an extension. Insulation can be added over the existing concrete slab or under a new one.

Btw the cost calc is wrong at the end. This will in no way be as warm as using proper insulation but it will make a noticeable difference. The floor hasn t got any. The final job to get done to make the room warm and usable.

Above the concrete slab if the insulation is placed above the slab the room will warm up more quickly when the heating is switched on but cool down more quickly too this applies to all internal insulation. As the barn had been converted in the mid 1980s and had been a swimming pool it is very unlikely that there is any insulation in the floor. Such spaces typically have a sound level concrete slab floor but lack sufficient floor insulation to achieve the thermal performance targets for new habitable rooms. Using a high quality rubber underlay will further add to the feeling of warmth.

Seeing someone s thread about a studio in their garden got me thinking about my garage s insulation. Super insulating an existing floor may pose problems with room heights in many buildings most modern buildings have insulation built into the floor structure. You d need to put in a damp proof membrane and then at least 100mm of polyurethane underfloor insulation topped with a concrete slab. Insulating a solid floor.

Where floors do include a dpm and show no evidence of moisture laying a floating wooden floor or thermal underlay with a carpet on top is often the easiest means of improving their thermal performance. Its very cold in the winter months and i reckon its down to the floor not being insulated. If you can t or don t want to take up the existing floor you can take up the plywood and add polyurethane to a thickness that head height allows then lay a floating laminate floor on top. A cheaper and easier option for insulating a concrete floor is to line it with chipboard sheets and then carpet over the top.

Good afternoon i was hoping someone might be able to give me some advice i have solid concrete floors with cement screed on top and they are cold very cold so i was thinking if i was to remove the 75 mm screed and put 50 mm king span down straight onto the concrete then a layer of 5 mm ply followed by 22 mm chip board interlocking floor boards would this have a dramatic affect on the floor.
