Recessed lighting has a bad reputation
Hello! I can tell from reading and from my own experience that Recessed Can Lights are a big frowned upon item for use in Green homes. Mainly the fact that they do not seal very well and are far from ‘Air Tight’ even if they say so due to a cheap gasket.
I have seen people use foil-faced poly iso and make boxes to place over the recessed can lights. These boxes can be air sealed without having to make contact with the light fixture.
I’m wondering, if this occurs, does it remediate the bad reputation due to air sealing? If so, has anyone had experience where the box iteself causes the lights to fail prematurely due to what I imagine would be heat build where as before it would seap into the attic?
