Why a hot tub cover needs replacing?
sergey:
Ok - I see the point. Agree - 6 years is Ok too.
Just wonder why manufactures do not do that (hard plastic inside) at their end. It should not cost too much.
Never mind - let it be the way it is now. I just like to enhance things if I see a way :)

If someone made a vacuum molded cover shell it could easily last 20 years or more. Not difficult and probably less expensive than sewing vinyl, but then the vinyl sewers might be out of work at some point!

but looks like the second one has no isulation
How about using Thermal blanket ? Like this : https://www.diypartcenter.com/products/hot-tub-thermal-blanket-miscellaneous-7ft-x-7ft-5235
it should increase live span of main cover - Am I wrong?

Thermal blankets do extend the life of the cover, your right, the foam blankets are better but a bit more expensive.
ROI.......foam thermal blanket 140 bucks. Cover lasts 6 years at 400 dollars. Thermal blanket extends life of cover one year? 2 years? Ummmmm do the math. The cover would have to last about 2.5 years longer to pay for the blanket. I dout it would.
However there is a small amount of energy savings also?????
Kind of a wash in my mind.
The Wizard of Spas:
Adding more and more to the inside of the cover does not reinforce the vinyl outer cover, which there will then be more and more stress at the seams. External elements can dry-rot the material, and stretch it out as well.
Point is - its not just one thing to fix, its a slew of interconnected things.
I hope this helps.
