Fire rated downlights and building regs

vantech

Hi,

What are everyone’s thoughts on this video about fire rated downlights and their necessity in 2 level domestic dwellings? 

JW has explained the reasons as to why they are apparently not required for certain installations, and this actually goes against what most manufacturers / wholesalers would tell you. 

YouTube video should be linked to this post.

Thoughts?

    Looks like AD B (dwelling) only requires 30min R For 2-storey houses. The E and I are not requirements as they are here in NI.

     We are rarely involved in domestic projects. On the commercial side BC officers often request evidence to demonstrate that elements of structure are appropriately fire-protected. So, for example, in a recent hotel refurbishment, the ceilings were required to be 90min REI. The ceilings were installed to British Gypsums White Book. For whatever reason, the electrical contractor installed downlights directly in that ceiling where, in fact, there should have been another ceiling below to accommodate such penetrations. 
    Even though the downlights were 90min, the assembly was rejected as there was no test data to support any claim that the floor above was adequately protecte.

    Indeed when the downlights were removed, it wasn’t a simple matter of repairing the ceilings. Large areas of plasterboard had to be removed before the repair was deemed appropriate.

    This applied to 40 rooms!
