High & Extra High Density Polystyrene
High-density polystyrene is often used for applications where high compressive strength (ability to carry load) is needed:
- Surface bed insulation below concrete floor slabs
- Above concrete roof slab insulation
- Raising existing concrete slabs
- Flotation applications such as hydroponics, floating jetties, pontoons, jacuzzi covers, etc
Medium Density Polystyrene
Medium density polystyrene is often used for applications where high compressive strength (ability to carry load) is not so important but insulation values are still important such as perimeter cavity wall insulation
Low Density Polystyrene
Low density polystyrene is often used for applications where compressive strength (ability to carry load) and insulation are not important such as:
Low density polystyrene is the cheapest option but if it need compressive strength then this is not the right option for you!
