Swimming pool basins
Although only a formal requirement in some parts of UK building regulations, thermally insulating swimming pool basins to reduce the energy demand of maintaining a certain water temperature makes a lot of sense.
To be clear, any U-value requirement for a swimming pool basin applies to the pool structure containing the water. The thermal performance of the building in which the swimming pool is located is subject to national buildings as normal, whichever country of the UK it is in.
For detailing purposes – including the specification and installation of waterproofing, and ensuring continuity of insulation – pool basins are almost always insulated around the outside of their structure. Like its suitability for basement applications, extruded polystyrene (XPS) insulation comes into its own. Its robustness when installed in contact with the ground, combined with its ability to bear the weight of concrete and water, makes it an excellent solution.
Polyfoam XPS Ltd is a leading manufacturer of closed cell, extruded polystyrene insulation. The Polyfoam range is lightweight, strong, moisture resistant and easy to cut and shape, providing thermal performance and strength for the lifetime of the building.
