We don't sell spray foam insulated spas.
1 - Spray foam is not the most efficient insulation system. Want proof? Just ask the California Energy Commission, the only regulatory body that actually tests hot tubs for energy efficiency.
2 - Spray foam holds water for a LONG LONG time. This means that your spa could be leaking slowly for months before you even realise there is a problem. Wet foam results in mould and before you know it you're out of warranty and your dealer wont fix the tub for free anymore.
3 - Once your spray foam insulation becomes waterlogged it loses its effectiveness as far as keeping the water warm & the weight of the wet spray foam also pulls lines and plumbing out of place. Just simple physics.
4 - If your spas pumps aren't given the space to breathe they can overheat and shut down. Another common thing we see with spray foam insulated spas.
5 - Spray foam is an attractive place for rodents to hide, and you can only imagine the issues that can be caused when you're housing a rat in your brand new expensive hot tub!
