ECN Forum Forums Code Related Discussion NEC & other Code issues Space between Recessed Can Housing

Hi,
Does article 410.13 require a space or non combustible material between the housing of the recessed fixture and the joist?

Can you use sheetmetal or sheetrock screws to attach a recessed can to a joist or wood framing member or do they not have to be wood screws?

Thanks for any replies.
