POLYTECH lightweight concrete

POLYTECH lightweight concrete (or styroconcrete) types 20/80 and 25/80 are the perfect thermal insulation material, levelling material or sloping surface material for a patio or a balcony.
For such purposes, we recommend a range of levelling and insulating Polytech mortars. They are made of cement,  regranulated (or granulated) polystyrene foam, the TECH foaming additive and mixing water. The mortars contain no mineral aggregate material, which gives the product its thermal insulation properties. 

If you are making a sloping surface on the roof of your building, we recommend the the Polytech lightweight concrete (or styroconcrete) types 20/80 or 25/80, which can be made using modified granulated polystyrene foam (the yellow bag*). 

The number in the name of the product indicates the proportions of the cement and regranulated (or granulated) polystyrene foam. These proportions determine the performance of the mortar, its intended use and method of application.

The type of the Polytech lightweight concrete (or styroconcrete) to be used and the thickness of the thickness of the insulation layer will depend on how the walls or ceiling to be insulated has been designed and constructed. Our professional technical and sales consultants will be happy to assist you.

Key benefits

  • The material will fill any gaps in a rough surface.
  • The mixture has a low volume density: 0.32 kg/dm3 (from 320 kg/m3)
  • Compression strength: 0.4 MPa (400 kPa)
  • The material offers very good thermal insulation performance, which helps to reduce thermal bridges significantly.
  • The binding and drying times are short.
  • It is a frost resistant material.
  • Fire resistance: Class: A2-d0, s1

*) MODIFIED GRANULATED POLYSTYRENE FOAM (THE YELLOW BAG)

Unlike all other mortars, the product packed in 200 L yellow bags is regranulated polystyrene foam modified with the TECH additive. Cement and water must be added in correct proportions at the building site. It is intended for making the POLYTECH lightweight concrete (or styroconcrete) types 20/80 and 25/80 (levelling and insulating mortars) in a free fall concrete mixer, a Kompatto mixer, an MP series mixer or any other low-speed mixing machine.

To make 1 CBM of the POLYTECH lightweight concrete (or styroconcrete) type 20/80, you will need

  • 4 Yellow Bags of modified granulated polystyrene foam, 
  • 8 bags (200 kg) of the CEM I, CEM II/B-S or A-S cement,
  • 120 litres of mixing water

To make 1 CBM of the POLYTECH lightweight concrete (or styroconcrete) type 25/80, you will need

  • 4 Yellow Bags of modified granulated polystyrene foam, 
  • 10 bags (200 kg) of the CEM I, CEM II/B-S or A-S cement,
  • 120 litres of mixing water
