Our experienced technical team will work with you to determine the best Styropool solution to ensure that your swimming pool meets Building Regulations.

Styropool is available in three different grades to meet the needs of a wide range of swimming pool types and sizes:

GradeCompressive Strength Design Load
Styropool 300300 kN/m2130 kN/m2.
Styropool 500500 kN/m2180 kN/m2.
Styropool 700700 kN/m2250 kN/m2.

The design load is that load on the insulation which will give a maximum compression of 2% after 50 years.

Styropool is manufactured from extruded polystyrene and is blown using recycled CO2. Styropool has Ozone Depletion Potential (ODP) of zero and Global Warming Potential (GWP) of less than five. It is 100% recyclable. Styropool offers exceptionally low water absorption with less than 0.5% after 28 days immersion.
