PolyRoof - Polystyrene Insulation For Concrete Roofs

On Special Today!


You can simply order directly online or request a quote.


PolyRoof Insulation Boards are designed to provide effective thermal insulation for both concrete and inverted roof applications. They are made from fire-retardant polystyrene and are proven to protect waterproofing systems from extreme weather and temperature. These boards have high compressive strength and are easy to install, making them the perfect choice for all concrete roof insulation needs.


If you are looking for high-quality polystyrene insulation boards for above concrete roof slab insulation then our polystyrene PolyRoof Insulation Boards are the right option & you can simply order them nationally online here!


Installing our PolyRoof Insulation boards on top of your concrete slab waterproofing and below the stone layer firstly protects your concrete slab waterproofing membrane from the sun and secondly insulates the concrete slab.


Protecting your waterproofing layer from the sun is an important thing to consider because maintaining your waterproofing layer every year from our sun in South Africa can be an expensive exercise!


Not only are PolyRoof Insulation Boards cost-effective, but you can be sure that they will give you the compressive strength and thermal insulation R-values that you need to meet building regulations in South Africa.


It is important to note that normal density polystyrene will fail in this application, so it is much better to order PolyRoof insulation Boards that are specifically designed for this application. You don't want to be uplifting the stone & polystyrene layers down the road only to install the right density & quality boards.


Each board is 3m2 so dividing your total insulation area by 3 will give you the number of boards you require.


Our PolyRoof Concrete Roof Insulation Boards are locally manufactured and delivered from our factories & depots in :


  • Johannesburg
  • Cape Town
  • Durban
  • East London &
  • Port Elizabeth

When you order online you will have the choice to either collect your polystyrene at our local factory or depot or for us to deliver it directly to you. Please note that our online platform deals with local deliveries around these factories & depots. You may have to call us for deliveries that are further out or simply choose to collect the boards yourself.

SANS 10400 Part XA Building Requirements For Buildings:


Concrete Roof Insulation is a building requirement, in terms of the SANS 10400 Part XA Building Regulations in South Africa. There are different insulation requirements depending on where your project is in South Africa.

The table below defines the Thermal Insulation (R-Value) requirements, for any roof, by region, in South Africa. This is the R-value of the entire roof system including ceilings.


Zone Locations Thermal R-Values
1 Johannesburg, Bloemfontein 3.7
2 Pretoria, Polokwane 3.2
3 Makhado (Luois Trichardt), Nelspruit 2.7
4 Cape Town, Port Elizabeth 3.7
5 East London, Durban, Richards Bay 2.7
6 Upington, Kimberley 3.7



Deemed - To Satisfy Design Requirements For Buildings:



In some cases, existing buildings can be insulated on Deemed-To-Satisfy design principles. Where the deemed-to-satisfy principle are acceptable lower insulation value requirements may be justifiable. Please consult with your architect to see if this principle applies.

In order to meet thermal requirements certain thicknesses or PolyRoof Boards will be required. Generally new builds require the SANS 10400 Part XA regulations to be met.



PolyRoof Board Thicknesses & Thermal Insulation R-Values:


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



PolyRoof Board Densities & Compressive Strength:


PolyRoof Insulation boards are sold in high density or preferably extra high densities to ensure the least amount of water absorption and compressive strength requirements are met.


  • It is best to consult with your engineers and architects to determine which density and thicknesses are best suited to your requirement.
  • Please be advised that low and medium density products will fail in this application.


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
