SmartCap attic recessed light cover is a pre-assembled, easy to install, fire rated recessed light cover that simply unfolds into a perfect cap over non-IC rated light fixtures in the attic. Unlike site fabricated light covers that require excessive time, labor and cost to build, SmartCap attic recessed light cover is an easy solution to a complex problem. SmartCap attic recessed light cover folds-out into position between attic joists running parallel to joists to easily cover both the light fixture and its accompanying electrical box. Designed for non-IC recessed light fixtures with a nominal diameter of 7 in. (178 mm) or less. It should not be used for recessed light fixtures with nominal diameters greater than 7 in. (178 mm). Allows attic insulations to achieve R-values in excess of R-60 with maximum insulation heights as high as 24 in. The surface burning characteristics of SmartCap attic recessed light cover were tested in accordance with ASTM E 84. Both the SmartCap attic recessed light cover facing and fiberglass interior veil were tested for resistance to fungi (mold and mildew) per ASTM C1338 and ASTM D 3273.
I bought 9 of these to cover my recessed lights before adding blow-in insulation. They are very flimsy and difficult to install in an existing batt-insulated attic. Of course crawling around any attic is a pain, but you have to pull the batting back pretty far from the lights to get the cover fully opened. Then you are supposed to tape it to your old drywall. That is also a pain as the surface is dusty and the tape doesn't want to stick. Also the covers keep wanting to collapse as you try to stick the tape down. Also, they are fairly tall, like 30" so you can't use them with limited clearance to the roof even if you can crawl back there. You also have to cut the sides out to clear the wiring to the lights. I got 5 installed after 3+ hours of laboring and fighting with them. Better and cheaper to replace your cans with brand new, air tight, IC-rated remodel cans. I took 4 back and bought 4 new cans for less. And it was was an easier job if you aren't afraid to disconnect and reconnect the can and wires through the recessed hole.
