A very good product for insulating recessed lights
on January 16, 2011
I just installed 15 of these in my 30 year old house with several recessed lights and fans.
It's a very good product and I wouldn't hesitate to recommend it. It is flexible which is important if the recessed light is pushed up next to a stud or a joist, or if there are wires going everywhere.
I got the large one, the FF135, rather than the smaller one, the FF130E, because I was worried that the tighter enclosure might harness too much heat and the larger one would be more flexible to use.
It was a good choice to pick the larger one because nearly all my recessed lights had an electric box offset from the light itself, and with the larger one, I was easily able to cover both the light and the electric box. This made cutting (or tearing) the slit in the cover smaller because there were few wires to negotiate.
There were some bathroom recessed lights that even this larger one didn't fit over. They had some sort of box rather than the cup going through to the attic. However, this box appeared well insulated already so I don't think covering them with this product was completely necessary. Since I didn't check the exact configuration of each recessed light before I ordered them, I after finding out that some of these were too large, I was worried that I ordered too many. However, it so happened that I had the same number of fans that I also needed to cover because they also had some air leaks, so I ended up using all of the ones I ordered.
After I installed these, I felt immediate improvement in the insulation of the house. Drafts were less and heat seemed to stay longer. (However, I when crawling around the attic I also patched up some open holes in a sky-light shaft that were obviously a big source of heat loss.)
This product is definitely worth it and considering all the recessed lighting (and the accompanying heat loss associated with recessed lighting) that is installed in our houses these days, I am surprized this product and others like it are not more popular. Insulating is so important and this product plays a key role.
One comment about this literature on this product. Yes, it is easy to install -- assuming you can just walk right up to the recessed lighting cup in your attic and install it. However, this is rarely the case.
My house, which has fairly accessible attics still proved a real bear to get around and install these. Anyone who has ever been around an attic knows exactly what I mean. Blown fibre glass insulation, electrical, cable, phone thermostat wires, vents, PVC pipes, and thin joists to walk around on (don't step outside the joists, or your be falling through the ceiling!!!), and years and years of dust. Of course, that's assuming you don't find any furry little friends or hornet nests. One of the recessed lights I needed to get to was way deep in the rafters in about 12-18 inches of blown fibre glass. By the time I got to that recessed light, I had crawled through about 8 feet of dusty old blown fibre glass with less than 2.5 feet of head room. Good thing I wasn't clautrophic and in fairly good shape (been doing pushups recently), otherwise, it could have been ugly. But, this isn't a comment about this product -- just a general comment about doing any type of work in the attic.
Bottom line: it is a good and necessary product for insulating when there are recessed lights (or fans that may leak a little air into the attic). However, any thing you do in the attic can be VERY HARD WORK -- you need to be extraordinarily careful (so not to mess up wires, duct work, step through the ceiling, etc.) watch your head so you don't gash your head with roofing nails, and it's very strenuous because you always are needing to duck and crawl around areas that aren't designed for human beings.
I give the product a 4 because I (a) think it could be just a little cheaper (but I am not complaining) and (b) because saying it's easy to install ignores the harsh reality that anything you do in an attic is hard work (even if installing this particular product is easy once you climb around the attic).
