I carefully followed instructions and the center section of the surround has fifteen hairline cracks about fifteen inches long…..the other four sections seem ok…bathroom is not heated all the time but never gets below 50 degrees…all materiel and procedures were to manufacturers specs…homebase gave me a new piece of material but I dont want it to happen again,….called the manufacturer in quebec about six times and got the usual leave-message-on machine routine…anyone have any ideas other than using tile (which I dont like)

If this is not a tub enclosure, but one of those flimsy wall surrounds, make sure it is not the cheapest one available. Your lack of heat may be shrinking that plastic. Then the quick on call heat makes it big again. It just might not be able to take it. Again, if it is a wall surround, did you trowell on the adhesive or use tube glue? If its a tub unit, try oversizing the fastening holes at the top. So it has a little room to move. Other than that, beats me. Best of luck.
*I used tube adhesive (as per instructions) then trowled using a notched trowel...the unit cost 125 dollars...(is that cheap)thanks
*Home base, Is that a big box store? Maybe, one of their trained associates jumped on the box and stressed the panel. You put it up and the cold warm cycle cracked it at those pts. I'd give it another shot, only cost your time. The old (new) glue might be a problem. 125 Canadian? In the states I would call the 59.95 one cheap. Keep us informed.
*It's called shock crazing. The hot/cold cycle will cause fatigue of the panels. This is the source of the cracks you mention. The real culprit is not so much the ambient air T, but that of the water. In a former life, I was a shift chemist working with the resins used to make this stuff. Back then, there was alot of experimentation to get the batch formulas right, but some crazed after only 200 cycles. All failed within the simulated 6 years. There have been advances since then, I'm sure, but it seems they are not far enough along.
