  Floors - Solid Floating Ground Floor Insulation


INTRODUCTION
For solid floating ground floors we recommend the use of Kingspan Thermafloor TF73 zero ODP composite floor insulation. A separate vapour control layer is not required and the boards promote quick response heating. Ideal for both newbuild and refurbishment.

ACHIEVING U–VALUES
The table below details typical thickness of Kingspan Thermafloor TF73 zero ODP required to achieve the various U–values to satisfy Building Regulations/Standards.
U-Values
1 Product Thickness = insulant thickness + 18 mm chipboard.

2 The l–value quoted is based on the procedures for the determination of the aged values of thermal resistance and thermal conductivity, laid down by the harmonised European standard BS EN 13164, using so called 90/90 principles. Comparison with alternative products may not be appropriate unless the same procedures have been followed.

3 For the purposes of these calculations using the method as detailed in BS EN ISO 13370: 1998, the soil has been assumed to be clay or silt, the wall insulation is assumed to overlap the floor insulation by 200 mm minimum and the standard of workmanship has been assumed good and the correction factor for air gaps ignored.

4 Insulant thickness only, does not include chipboard.

Note:
In the case of a non–ground floor, please refer to the Kingspan Insulation Technical Services Department.
FIXING DETAILS
  • Ensure floor surface is smooth and flat. Sand blinding may be used to achieve this.


  • Lay boards in a “brick pattern” and glue the chipboard using joints PVA adhesive applied to the top and bottom of the tongue and groove.


  • Insert wedges between the wall and floor to maintain tight joints whilst the adhesive sets. Replace the wedges with Kingspan Styrozone® to act as a compressible filler.


  • An allowance of 10 mm or 2 mm per metre run of floor, whichever greater, should be left against all walls and abutments. Over a large run of floor, intermediate expansion gaps may be required (please contact the Kingspan Insulation Technical Services Department for further details).


  • Ensure the building is weather tight before fixing floors incorporating this product.


    • Cutting should be carried out using a fine toothed saw.
