Area calculator

Thermal Calculations

In order to calculate how much floor insulation is needed, please refer to the P/A (Perimeter / Area) table above.

The perimeter / area ratio is calculated by dividing the length of exposed perimeter wall (in Meters) by the floor area of the room to be insulated (in square meters).

The exposed part of the wall is any wall which is connected to an unheated space e.g., the outside of the building.
Rooms with less exposed perimeter will require less insulation and vice versa.

Example Calculation

A living room to be insulated has a total floor area of 16.4 square meters. Along the perimeter of the room, there is 5.3 meters of wall which is attached to the outside of the building.

Therefore, the p/a ratio is: 5.3 divided by 16.4 = a p/a ratio of 0.33. This figure is rounded up to the nearest figure on the table which is 0.4

If the U Value requirement for the room is 0.22W/m2k, the 118mm Styrofloor® board would be required which achieves a slightly better U Value at 0.21W/m2k.

Conservatories

A conservatory floor is an important construction element and incorporating insulation is vital. All year-round use of the conservatory will be enhanced by installing Styrofloor®.

Styrofloor® should be installed on a dry concrete or beam and block base without a screed.

Styrofloor® is a floating floor and expansion gaps must be provided around the perimeter. Floor coverings such as tiles, carpet and laminate flooring are all compatible with Styrofloor®.

Garage Conversions

The conversion of garages into a living space is a growing trend. Effective floor insulation is essential for living areas as it continually reduces costs and provides environmental benefits. Transforming the garage floor is made simple by the use of Styrofloor® insulated flooring. One simple operation to fit insulation and a floor surface. Just apply your chosen floor covering for a final finish.

Lofts

Styrofloor® floor insulation boards can be laid over joists to improve energy saving in the loft space. It also provides a surface suitable for storage and foot traffic. (Please note: You should consider the need to comply with building regulations, which may be more involved in large loft conversions where a fire resistance is required.)

Summer Houses /
Garden Rooms

Styrofloor® offers the perfect solution for your summer house or garden room, providing both effective insulation and simple installation.

New Build

The design of floor systems to achieve Part L of the Building Regulations is easily achieved when specifying Styrofloor® insulated flooring panels. A range of standard boards are available for delivery to mainland UK. Depending on the method of floor construction there is a corresponding thickness of Styrofloor® to achieve your required U value.

Renovation

Styrofloor® is suitable for use when upgrading/renovating an existing floor. If the floor is sound and dry Styrofloor® can be laid directly over the existing structure. If the floor is damp then it is good practice to install a polythene layer before the application of Styrofloor® insulation boards.

Step One:
Floor preparation

Styrofloor can be laid on existing or new floors. On existing floors, ensure that the skirting is removed and where necessary level use a proprietary levelling compound. New concrete floors should be left as long as possible before laying Styrofloor to allow adequate time to dry out. Providing that the new floor is level, the use of a floor screed in not essential.

Step Two:
Damp proofing

The incorporation of a damp proof membrane should be in accordance with established building practices (see BS8102). In the absence of a damp proof membrane, a 1000 gauge polythene sheet can be used prior to laying the Styrofloor. Where continuous flexible sheet (e.g. PVC) is used, it should be turned up at the wall abutments.

Step Three:
Setting out

Ensure that all subsequent boards are positioned so that cross-joints are staggered to produce a brick pattern. All joints should be bonded using water resistant PVA adhesive. When laying adjoining boards, ensure that the tongue and groove joints are engaged and then tap each board with a suitable block to ensure it is tight-up against the adjoining board.

Step Four:
Laying your floor

The Styrofloor boards should be laid with a 10-12mm expansion gap at all abutments, between walls and the chipboard.

All joints should be bonded using Water Resistant PVA Adhesive, to obtain the best results, allow the adhesive 24 hours in which to harden.

Wedges/spacers can be used between the wall and edge of the Styrofloor to help press tongue and groove detail together while the glue hardens.

Step Five:
Finishing up

To obtain the best results, allow the adhesive 24 hours in which to harden before removing wedges. Check that expansion gaps are clear prior to the fixing of skirting boards. Should there be any unevenness, Styrofloor can be sanded down to the required level.

The final floor finish can now be laid directly onto Styrofloor. Carpet, laminate or tiles can be used onto the chipboard which provides a sturdy and long lasting finish.
