Insulated Solid Floor Construction

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

Insulated solid floor construction.

Solid floor insulation cost. Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding. The panels provide a continuous energy efficient surface. Most newer properties will already have solid floor bases constructed directly below a room especially on the ground floor.

This eliminates thermal bridging which is the energy lost through wall studs. There will be a damp proof membrane under the insulation and possibly a second membrane on top depending on the type of screed. Polyurethane pur is a more effective insulator than expanded polystyrene eps meaning a thinner board can be laid to achieve the same results. Renovation of more than 25 per cent of a solid or suspended floor involving the replacement of screed or a timber floor deck would have to meet the standards required by the building regulations approved documents.

The building regulations backstop target u value for ground floors is 0 25w m2k which should be easily achievable with 75mm or 100mm thick rigid insulation boards laid over the surface. These sections deal with in one way or another the values called u values which a home should be insulated to and the energy which is saved by implementing this insulation. Insulation under ground floor slabs is a good way of meeting the increased requirements of parts l f of the building regulations. Heat loss thermal insulation there are three general types of ground floor construction.

The studs conduct more heat than the insulation between them. Insulating a solid floor. If the floor is a ground floor provide resistance to. A typical way of constructing a solid floor would be to provide a base of hardcore with sand blinding with a layer of concrete over that.

Read more about changes to thermal elements in the external walls section. 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. Insulation is laid on the concrete and covered with a screed. 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.
