We are about to install a rimless ceramic induction hob into a granite worktop so that the edge will be as seemless as possible with hob and worktop at same height. The supplier is saying that there needs to be a 2-3mm gap filled with silicone to allow for expansion.
- What expansion? The ceramic glass surface is cold, and with induction, even cooller than normal element or halogen. Less than 1mm would appear to be more than adequate.
- Is silicone the best material? It will doubtless be rough and as thi sis an area that will be cleaned oftenm how long will it last.
Any thoughts?
Thanks
Andy Bernard
