Re: IC recessed cans
When in the State of New York, ALL installations are required to follow the the 8 documents (books if you want) that make up the NYS Fire Prevention Code. In the Energy Conservation Construction Code (one of the 8 documents/books)there is a section 502 in Chapter 5. Section 502 is the building envelope requirements.
Section 502.1.3 Recessed lighting fixtures.
This section tells you that when the lighting fixture PENTETRATES THE BUILDING ENVELOPE there are three accepted methods of installation. Air seals/air locks are one of the methods.
If you are using an air seal fixture, it has to have a label with ASTME 283 on it. This is the label that says the manufacturer has built it according to the proper specs.
There are some recessed fixtures that are 'CONVERTIBLE'. These cans use different type of trims to designate if they are air seal or not. The air seal trims will require the installation of smaller wattage bulbs and be limited to certain trims, so be careful.
