Product Details


Luxury Buildings Start With Quality Floor Slab Insulation!



When you want a luxury ambient temperature floor all year round then PolyFloor Surface Bed Insulation is the right product for you but remember you only have one chance to install it and that is before you cast your concrete floor slab!


Energy efficient luxury buildings always start with quality floor insulation, then wall insulation and then roof insulation. Together they ensure that the whole building envelope is insulated properly.


Having a floor slab that maintains its temperature at room temperature all year long makes for luxury living and if you are going to install underfloor heating then it is mandatory that you put it in. Even without underfloor heating this product will reduce your heating costs in the cold months significantly.


PolyFloor, High Density Polystyrene Insulation Boards, are probably the most cost effective way to insulate your concrete floor slab. Just divide the board price by 3 to get the m2 price.


It really matters and it really works!

Surface Bed Or Below Grade Insulation


  • Surface Bed Insulation is the layer of insulation that is placed between the compacted soil below a building before the concrete floor slab is cast.

  • This special insulation layer stops the cold from being transferred from the soil below the building to the floor slab in cold winter months.

  • When underfloor heating is installed and being used, this insulation layer stops the underfloor heating from having to heat the slab and the soil below the slab. This in turn significantly reduces the amount of electricity that is required to keep the slab warm and comfortable underfoot.

  • Irrespective of whether or not underfloor heating is going to be installed, having this cost effective layer in place keeps the concrete slab at ambient temperature.


SANS 10400 Part XA Building Requirements For Buildings:


Surface Bed Insulation is a building requirement, in terms of the SANS 10400 Part XA Building Regulations, whenever underfloor heating is going to be installed but is it should be installed anyway to ensure that the whole building envelope is properly insulated.


PolyFloor Thicknesses & Thermal Insulation R-Values:


The building code states that in residential developments a minimum thermal R-values of 1 should be achieved.


This is achieved by installing a PolyFloor Insulation board of minimum thickness 35mm. Obviousely the thicker the PolyFloor Boards the greater the thermal insulation. In residential and commercial buildings 40mm, 50mm & 75mm boards are most commonly specified.


We recommend a minimum of 40mm in residential buildings.


Board Thickness Thermal Insulation (R-Value)
35mm 1.000 (Residential Insulation)
40mm 1.143 (Residential Insulation)
50mm 1.429 (Residential Insulation)
75mm 2.145 (Residential Insulation)
100mm 2.857 (Residential Insulation)
120mm 3.429 (Cold Room Insulation)
150mm 4.286 (Cold Room Insulation)
200mm 5.714 (Freezer Room Insulation)
300mm 8.571 (Freezer Room Insulation)


PolyFloor Densities & Compressive Strength:


PolyFoor Insulation is only sold in High & Extra High Densities due to the loading and compressive strength requirements of the boards in this applications.

  • In residential applications a high density board can be used.
  • In commercial or Industrial applications and Extra High Density (24kg/m3 to 30kg/m3) must be used.
  • Low and medium density polystyrene will fail in this application.
  • Consult with your local engineer is you are uncertain.


Type Density Compressive Strength
High Density 20 kg/m3 110 KPa @ 10% Compression
Extra High Density 24 kg/m3 to 30 kg/m3 160 to 200 kPa @ 10% Compression
