High density foam insulation
Foam between the spa shell and cabinet creates a thermal barrier which insulates and retains heat, whilst protecting the plumbing and improving energy efficiency.
Our own insulation which is partial foam with a twist. Not only do we spray expanding micro-pocket foam onto the shell forcing heat transfer to convert rapidly between conduction and convection, but on the panels we incorporate a second layer of foam fronted with an infrared reflecting material to bounce back heat to the shell. In addition to this we also insulate the floor . This triple micro-pocket foam protection caters to second most source of heat loss (Household equivalent = double glazing).
