PolyFloor - Polystyrene Insulation / Surface Bed Insulation Boards
PolyFloor – Luxury Concrete Floor Insulation
ON SPECIAL NOW!
If you are building a new luxury home, office or building then you should really insulate your concrete floor slab before you cast it because it is not expensive, and it keeps your concrete floor slab at ambient room temperature all year round.
A cold floor slab means a cold house and if you plan to install underfloor heating then surface bed insulation is a building requirement in terms of SANS 10400 Part XA.
There is no point in making your underfloor heating system, heat the concrete slab and the cold soil layer below.
Your underfloor heating system should only keep the concrete slab at room temperature, and this does not consume a lot of electricity if this insulation layer is below the concrete slab.
Our PolyFloor, High & Extra-High Density, Fire-Retardant, Polystyrene Surface Bed / Underfloor Heating Insulation Boards are very cost-effective in this application.
Thermal Insulation Values & Requirements:
To get the required thermal insulation R-Value of 1, in terms of South African Building Regulations, you need a minimum board thickness of 40mm but the thicker you go the more insulation you get.
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.
|Board Thickness||Thermal Insulation (R-Value)|
||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 if you are uncertain.
|Density Name||Nominal 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|

How To Install PolyFloor Insulation Boards

- The soil is then placed and compacted.
- A DPC plastic layer is them placed on the compacted soil.
- 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.
