We have a 20-yr old four seasons sunroom with some of the original glass panels. While the roof does not leak, the panels "failed" a long time ago and provide no R-value, don't block UV and look like #$%^& to boot.
I contacted the manufacturer about replacing the glass panels with laminated foam panels and was told yes ... and they were a "little" less expensive than the glass.
That sounded bogus (and self-serving) to me and I decided to research it on my own. Sooo, here I am!
Should I not be able to purchase aluminum/foam laminated panels for a fraction of the cost of their "special" glass?
