Good QOD! Very common issue here in my area.

I used to know the answer to this one, but I was reading the label on the fixture at the time.

Gerry, you’re going to take some flack on this one I think. 2003 IRC E3904.8 and E3904.9 define what I follow regarding this but it’s not one of your choices. It’s a matter of semantics, i.e. combustibles -vs- insulation.

Hi Michael,

yes you’re right I realized too late how I had worded it and I can’t edit questions once posted.

Hi to all,

Yeah I meant insullation, luckily most people knew what I was getting at.

The correct answer is 3 inches

Strangely enough clearance to combustibles is only 1/2". Go figure.

Ironically…combustibles take ALOT of heat to ignite…while causing a recess light to not be able to VENT properly can keep a LARGE amount of heat in…the issue is not ignition of the insulation at FIRST…it is the fire that could start in the recess lights itself from NO venting and air space…

Just some FYI info…:smile:
