Solid Concrete Floor Insulation

Solid floors are insulated using rigid insulation foam which can be fitted either above or below the concrete.

Solid concrete floor insulation.

I am looking for some advice regarding insulating my cold living room. These constructions typically feature a 75 100 mm screed layer above a thick concrete floor slab. If the ground floor of your house is made of a solid concrete slab or flagstones or similar with no air gap underneath then you may want to consider solid floor insulation. Whilst heat rises it is also very important to insulate the floors as part of the total building envelope.

It is an oddly designed house and the living room is down three steps from the rest of the house. Floor insulation ecotherm offer thin rigid floor insulation boards suitable for solid concrete timber and suspended floors. Most newer properties will already have solid floor bases constructed directly below a room especially on the ground floor. When uninsulated they will both have a u value of between 0 45w m 2 k and 0 70w m 2 k but this depends on the geometry of the floor and the amount of thermal bridging.

In a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system. Floor insulation is the best solution when boards or tiles are draughty damp or cold to the touch. Insulating a solid floor. There will be a damp proof membrane under the insulation and possibly a second membrane on top depending on the type of screed.

Consequently they can be cold to the touch and are difficult to thermally insulate. If the insulation is above the concrete the room will heat up more quickly in the morning. The three retrofitting options are. Solid floors however present an altogether different challenge.

If the concrete is above the insulation it can sometimes store heat during the day which helps keep the room warm at night. It has a solid concrete base. The dilemma i have is how best to insulate my living room floor. Rigid insulation such as kooltherm k103 floorboard can be cut with a fine toothed saw and slotted between the floor joists.

Insulation is laid on the concrete and covered with a screed. Most modern homes have a solid floor for example. These can be fitted with new rigid concrete solid flooring or fixed plasterboard that should help fill any cracks or gaps formed over time and improve the overlay s insulating properties. Some houses have a ground floor that is built of horizontal timber joists with floor boards or other boarding over the top and a gap underneath.

Solid floor insulation cost. Where concrete floor slabs. Solid floors of brick tile or stone were frequently laid directly on to soil sometimes with a bed of lime mortar or sand.
