PolyFloor - The Cost-Effective Surface Bed Insulation


If you are looking for a cost-effective polystyrene product for below concrete insulation applications then PolyFloor, Fire-Retardant, High or Extra-High Density polystyrene surface bed insulation is a great option.


PolyFloor Insulation Boards are locally manufactured in Johannesburg, Cape Town, Durban, East London and Port Elizabeth. We sell directly to the public and in bulk to building contractors. We deliver nationally or you can collect and we also export.


PolyFloor Insulation Boards are 3m2 in size and are available in various thicknesses depending on the thermal insulation requirement. To calculate how many boards you need, just divide your total floor insulation area (m2) by 3. So if you need 300m2 of floor insulation you are going to need 100 boards.


Find out more about our PolyFloor Insulation Boards, thermal and compressive strength properties below and when you are ready, just order them nationally online, directly from factory here.


About PolyFloor Insulation & Concrete Floor Insulation


Thermally-efficient buildings start with quality floor insulation so insulating your concrete floor slab, before you cast it makes a difference!


PolyFloor insulation is the layer of engineered polystyrene insulation that is placed between the compacted soil bed and the concrete slab before it is cast.


Concrete floor insulation is not expensive and by installing it your concrete floor slab will remain at room temperature all year round instead of becoming excessively cold to the touch during our winter months in South Africa.


Of course, if you are going to install underfloor heating then concrete floor slab insulation is a building requirement in terms of SANS 10400 Part XA. It will reduce your underfloor heating costs significantly!


PolyFloor, High-Density, Fire-Retardant, Expanded Polystyrene, Concrete Floor Insulation Boards are an extremely cost-effective product to use in this application.


We recommend 40mm or 50mm PolyFloor Insulation Boards In South Africa to meet the minimum thermal insulation requirement (R-Value of 1) in residential buildings but often clients choose to install thicker boards for more insulation. Find out more about the thermal values, compressive strength and installation of this product below.


You should also have a look at our PolyWall - Cavity Wall Insulation Boards because these are more that often ordered at the same time as our PolyFloor Product.


PolyFloor Thicknesses & Thermal R-Values:


Thermal R-Values are thermal insulation values, not to confused with costs. They are a measure of the thermal insulation that a product will provide by thickness of material.

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


When Should You Order These Boards?


These boards should be ordered when the foundations are being built and a week before you are going to cast the concrete floor slab!

  • The polystyrene is then cut and laid tightly on top of the plastic layer.
  • Steel mesh is then placed on top of the polystyrene insulation layer with spacers.
  • The concrete is then poured on top of the polystyrene insulation layer.
