Welcome to our forum.
Would it have to be a spa blanket??Would siliconing a plastic sheet to the bottom of bothhalves of the cover have mostly the same effect?
Dr Spa is correct and more over a plastic sheet will not give you any insulating benefit, the major reason for using a Spa Blanket.If you have never seen a spa blanket it is made up of thousands of plastic encapsulated air bubbles, like packing material, which gives it it's insulating abilities.Regards, Zz
Hi ZZ,Just two quick points about your last post:1.) You won't have to replace your ozonator after 2 years of service, you simply have to purchase a replacement chip. This should cost you about $40. You will easily save much more than that in reduced chemical purchases over the next 2 years.2.) The materials used in headrests today (Jacuzzi, HotSpring, and others) is much more durable than the materials used in the past and say what you will, many people agree that it makes for a more comfortable, relaxing hot tub experience.
