Heatform Panel Pools

The insulated pool panel that doesn’t cost the earth.

Liner pools have been around for over 50 years and the main build technology has not really changed over those years. You build a concrete or PVC panel ‘pool-basin’ put a liner into it and then fill it with water.

Heatform has transformed this process not only making it quicker, easier and simpler to build that ‘pool-basin’ but with the added value of insulation. The main idea around Heatform is to keep those expensive heating bills to a minimum and reduce the amount of energy that is wasted.

Not only are we reducing the amount of energy being wasted through heat loss, but we are also helping the environment by using empty plastic (PET) bottles to form the insulated section of the pool wall. 100% made of post-consumer (recycled) PET material, our green foam core meets not only stringent technical requirements for composites but also follows the guidelines for circular economy and helps to preserve and enhance the human environment.

From an empty bottle to a genuine foam core!

Every Heatform panel incorporates a unique insulation material 100% made from recycled plastic bottles. For example the 2.5m panel has approximately 768qty x 500ml recycled (post consumer) plastic bottles.

Polyethylene Terephthalate (PET) foams are the newest structural core materials in the composite industry. Heatform’s insulation is well established among core materials for sandwich structures and is steadily substituting traditional materials such as Balsa, SAN or PVC
The reason is simple: with outstanding product quality, tremendous diversity of uses and truly sustainable production, Heatform’s insulation offers you new perspectives toward your pool’s energy saving potential. 
Lightweight and high mechanical strength in conjunction with residual flexibility and maximum service life are what you expect of a modern composite material, and that is what you get from us, with a great deal more.

  • Excellent fatigue properties: The long-term behaviour of sandwich structures is a major concern for dynamically loaded applications. Heatform’s insulation displays a threshold level of >60%.


  • High temperature resistance: Higher curing temperature means shorter cycle times, increased productivity, better mechanical properties in the laminate and peel strength. At +150°C Heatform’s insulation allows a process time of days with full vacuum.


  • Limited density variation: The mechanical properties are all related directly to the density; even small variations have a big impact. Heatform’s insulation extrusion process keeps density variations rather low, at less than 5%.


  • Process versatility: High-performing core material is of less use if it adds complexity and costs to the manufacturing process. Heatform’s insulation is compatible with various production methods like infusion or pre-preg, as well as with all common resin systems.


  • Thermoformability: Due to its thermoplastic nature, Heatform’s insulation is well-suited for thermoforming. 3D-shaped or double curved sandwich panels are possible without cutting the foam and thus eliminating core stress concentration and increased resin consumption.


  • Recyclability & sustainability: Heatform’s insulation is 100% recyclable after its use phase. Furthermore, it is already 100% made of post-consumer PET and is still recyclable afterwards. You cannot find a more sustainable foam core in the composite industry!

EN 45545-2 certification requires the testing of the final composite sandwich, laminates plus core material.
