Bill,

Your method is just dandy, because you aren't describing an incorrect method of joining Corian to another material.

one of the issues with Corian, and why you weren't able to purchase it as a raw material 'back in the day', was the improper installation that led to cracking. There's literally ONE approved way of attaching it, as I've described.

Our installation methods were warranted by DuPont for 20 years. I've seen hack installs last a day....literally. Corian grows with heat, and it grows quickly. Anything restraining its growth will cause a crack.

Water boils at 100 degrees Celcius at one atmosphere and you attach Corian horizontally with silicone.

Anyone claiming differently is presenting 'personal oppinion' and not actual fact.
