Styropool
XPS (Extruded Polystyrene) for insulating swimming pool structures
The Ultimate Solution to Swimming Pool Insulation
Styropool is made from Ravatherm XPS X (extruded polystyrene) and is available in three different grades to meet the needs of a wide range of swimming pool types and depths.
Benefits
Provides a long-term solution for insulating swimming pools, helping to create energy efficient pools with low running costs
Achieves thermal resistance up to 4.83 WmK
Manufactured to order in Sheffield, from stocked materials
Technical
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:
| Grade | Compressive Strength | Design Load |
| Styropool 300 | 300 kN/m2 | 130 kN/m2. |
| Styropool 500 | 500 kN/m2 | 180 kN/m2. |
| Styropool 700 | 700 kN/m2 | 250 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.

Applications
Styropool can help create energy efficient pools with low running costs whilst also meeting current Building Regulations. The benefits include:
- Excellent thermal performance in order to meet your project thermal requirements
- High compressive strength, making it ideal for insulating the base and retaining walls of a swimming pool
- Exceptionally low water absorption and can be installed directly below concrete
- Supplied from our Sheffield warehouse for collection or delivery throughout the UK
Styropool and Building Regulations
Building Regulations Part L1A 2010 requires a swimming pool that is part of a dwelling to achieve a minimum thermal performance, equivalent to a U value of 0.25 W/m2K. The U Value is derived from a combination of variables including:
Ground Type
Differences between soil type may impact on the calculation.
Pool Construction Method
Every material component contributes to the overall U value, and this will vary from project to project.
Structural Demands
This will determine the grade of Styropool and its associated thermal performance.
P/A Ratio
Where P is the perimeter and A is the pool area. The higher the P/A ratio the more insulation required.
Pool Shape
The shape of the pool will impact the P/A ratio where the pool area is constant.
Depth of Pool
The greater the depth the better the U value.
Insulation Location
Styropool can be installed below the structural element of the swimming pool. The closer the insulation is to the heating source, the faster the insulation will respond, and the pool temperature will rise faster but decline faster when the heat source is switched off. When located below the structural element, it will create a heat sink and therefore once at temperature the pool will have a much slower heat loss if the source is switched off.
Typical Example
