Frequently used in cheap, unbranded hot tubs from the far east, expanding foam is a low-cost and
easy way to support a flimsy hot tub shell.
Foam filling also prevents pumps from "breathing" inside the cabinet, so large vents allow this
heat to escape, rather than re-using it.
Foaming also means that cold air is sucked into the spa water by the jets, where Monarch spas take
warm air from inside the cabinet, heated by the pumps, to reduce the cooling effect on the water
which affects so many other brands.
This foam emits high levels of VOCs
(Volatile
Organic Compounds)
during application. As well as damaging worker's lungs, the environment suffers too, as these
by-products of the foam application process enter the atmosphere, ground water and soil.
Just to prove our point, we compared our Earl hot tub against a fully-foamed competitor's model in
terms of actual daily running costs. Click here for the comparison:
