P5 grade chipboard is a high duty board designed for floor use including humid applications. The chipboard incorporates a tongue and groove detail on all four edges for ease of installation. Our Chipboard is moisture resistant grade P5. Ravatherm XPS is a closed cell insulation board with good water resistance. This eliminates the need for a vapour control layer in the floor construction. Ravatherm XPS is extruded with a unique blue colour to clearly identify the product.
Styrofloor can be used to insulate floors in residential and commercial projects for both new build and refurbishment. It is also suitable for use in conservatories or conversion projects.
We pride ourselves on our high level of quality & service and all our products are manufactured to British Standard BS EN ISO 9001:2015. We keep extensive stocks at our Sheffield warehouse close to Junction 31 off the M1, ready for collection or distribution across the UK.
IMPORTANT INFORMATION (6th Nov 2019):
The insulation foam used to make Styrofloor - Dow Styrofoam, has changed brand name to Ravatherm XPS. This product is now manufactured by Ravago Building Solutions – Europe’s largest manufacturer of XPS insulation. The level of quality has remained the same. If you have any questions regarding this name change, please contact our technical sales team.
- Blue Styrofoam LBH has changed to Grey Ravatherm XPS XH LB

P= Exposed Perimeter of Floor (Metres) A= Area of Floor (Sq. Metres)
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 visa 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.

Applications
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.
Garages
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.
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 appropriate to install a polythene layer before the application of Styrofloor insulation boards.
Installation
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.
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.
FAQ's
What size is Styrofloor?
Styrofloor is 2400mm in length by 600mm wide. Approx. 8ft by 2ft
What is the weight of Styrofloor?
Each Styrofloor panel weighs between 18Kg to 26Kg (40lbs to 57lbs) depending on the foam thickness.
What thickness of Styrofloor is required?
This will depend on two important factors. If the project is subject to Building Regulations then there will be a need to achieve a certain thermal performance i.e. U value. In this case, refer to our Insulation Properties section. If the project is not subject to Building Regulations then you can choose whatever thickness you can accommodate in your construction. The thicker the panel the higher the level of energy saving.
Are there any other product options?
Styrofloor is available in bespoke thicknesses to better suit the application and/or thermal requirement. Styrofloor can also be supplied using 22mm chipboard where heavy foot traffic is anticipated. Contact our Sales Office for more details on 0114-2495626
Is Styrofloor resistant to moisture?
Yes. The chipboard grade is suitable for humid conditions. Ravatherm XPS is a closed cell foam and therefore resistant to moisture.
INSTALLATION
Are fixing instructions available to download?
Yes. See our installation page.
Will Styrofloor require fixing to the floor?
Styrofloor is laid as floating floor system and therefore does not require direct fixing to the floor.
What if the floor is uneven?
If your floor is not level then use sharp sand to fill up to a max. of 10mm. Over 10mm use a self-levelling compound.
What types of floors are suitable for Styrofloor?
Styrofloor can be used on most floor construction system including concrete, beam and block and timber. In the case of timber, the joist widths must be 50mm min, and be set no more than 400mm apart.
I have a U value to achieve, which thickness do I need?
Refer to our detailed How To Buy page which provides a simple calculator for selecting the Styrofloor thickness. If required we can provide a detailed calculation to support the required thickness. Please contact our sales office on 0114-2495626
Can I lay ceramic tiles over the Styrofloor?
Yes. The choice of adhesive and grout should be for a floating floor and the Tile distributor should advise of suitable brands.
Will the floor construction require a damp proof membrane?
Yes if required by the floor construction.
Will a vapour control layer be required?
No. Styrofloor is laid without a vapour control layer.
Can I use electric matting UFH over Styrofloor?
Your UFH supplier should advise on it’s suitability for installation on a floating floor.
Can Styrofloor be cut?
Yes. Use a fine tooth power saw or similar.
