Liner Renovation xx

Please read all notes, installation graphics, pictures and video prior to ordering materials.

Material thicknesses for So-Soft insulation finish:

Swimming pool liner is laid directly onto Thermapool insulation. So-Soft is only advisable for domestic pools using pre tailored liners. So-Soft gives the swimming pool a softer carpet feel, but you may be able to see joints in the insulation or the where fixings are.

  • 75mm Thermapool Insulation Board.
Total thickness 75mm Material thicknesses for insulation and render finish:

This gives the insulation a solid uniformed hard finish recommended for schools or for on-site lined swimming pools.

  • 75mm Thermapool Insulation Board.
  • 4.5mm Thermapool Render and mesh.
Total thickness 80mm Recommend number of fixings:
  • 4 fixings per wedge
  • 8 fixings per insulation sheet

Fixings should be installed 70mm in from the edges and spaced evenly, more fixings maybe required if the boards does not sit flat onto the pool structure.

Bonding the insulation

Bonding is only required if the structure of the pool is not sound enough to take a mechanical screw fixing, bonding materials are extra.

If bonding Thermapool Insulation, use Thermapool Insulation Adhesive on both the swimming pool structure and the back of the Thermapool Insulation Board, pushing them firmly together to achieve 100% adhesive bed.

Insulating around Corners

Radius corners should be insulated using the bendy boards slots are manufactured into the board to allow it to fit around the curve, which should be secured using the same methods as details for the panels above with any gaps being filled with the insulation adhesive.

Pre Installation Notes

For liner swimming pools the Thermapool insulation boards are usually secured to the walls and floor of the pool structure using a stainless steel screw, with a washer and raw plug. If the structure of the swimming pool is not sound it may be necessary to bond the insulation boards to the wall or bond and use the mechanical fixings.

We provide chamfered (75-0mm) wedge shaped insulation boards for the top of the swimming pool, this allows you to use the existing coping stones and liner lock without the need for any modification to them. If coping stones are to be replaced then the chamfered board is not required, please see new build installation guild for this technical installation detail.

Pool fittings

There are two options to insulating around existing fittings like inlets, lights, sumps, drains and vacuum points:

Option 1: The preferable method is to extend the fitting so that they are flush with the new insulated finish. The fittings can be extended using the tread on the existing gasket cover plate, insert a male male nipple into the cover plate and then tread on a new eyeball inlet cover plate to bring the fitting flush with the insulation finish.

Certikins product codes: Nipple GP112NMT or Nipple GP112THN and Eyeball inlet HD53L

Option 2: Alternatively we can provide chamfered insulation panels, see technical drawings for details. Note, if the fittings are not Certikin's standard white we will need to know the outside diameter measurement of the fitting at time of order placement.

Note - you will need to inform us which of the above you intend to do when ordering your Thermapool insulation system.
