If you wouldnt mind while your there theres another material I have been curious about. It's a type of insulation, it's reflective on both sides and has bubble wrap sandwiched in between.

Reflectix? Got a value of about R-3, about 85% reflective, kind of expensive for the coverage. PITA to hang, as it has enough shape memory to want to curl up. Dulls knives incredibly fast. Staples dimple it up- Hot spots? Tough to shape into a tight corner, but works well on a frame.

OK, I made the trip to Home Depot today, light meter in hand ... in a nutshell, the shiny white 'pebble-grained' fiberglass shower-enclosure-type paneling' was a BAD reflector of light (15 foot-candles on my meter)... very disappointing, but, it was too expensive for me anyway $$$$ ... same for some white 'plastic' panels they carry, poor reflective qualities (15-18 footcandles) ... their 'flat-white Melamine-surfaced particle board' was MUCH better (25 footcandles) ... it reflects the same as flat-white paint, (which is pretty good, overall) ... it is available on 4'x8' sheets from 1/8" thickness to at least 3/4" ... that's probably what I'll use for my new cabinet ... I'm using Mylar now, and while it reflects the best when NEW, after a couple cleanings, it fogs, scratches, etc... I think I'll buy the Melamine-surfaced sheets, as they should be easy to clean, and durable, cleaning-wise ... this experiment wasn't very technical, I just measured the light falling on each board from Home Depot's overhead lights, but it seems to indicate comparative reflectiveness just fine ... I didn't find any of the 'bubble-sandwich insulation' ... :smokin:

I used the bubble wrap stuff in my cabinet. I thought it was easy to work with. I cut it to height then fastened the corners with 1"x2" bats which I then covered with silver tape. It's a bit of a PITA, but so are most things in life in one way or another. LOL

hey reaper dont know if you have a Menards where your at but they sell that insulation wrap ur talking about...:thumbsup: Its reflective with the foam/something similar type center?. It comes in rolls (that ive seen), not sure how big the rolls were maybe 25 feet or so. this is the stuff you are talking about right?..see pic

sorry here the other one with the bubble wrap

[the image reaper]

yes, that's the 'bubblewrap' they were talking about ... at the time, I didnt know what it was, and didnt see it ... I will try to test it tomorrow, I'm going to Home Depot ... the manufacturer's website claims it is 'up to' 97% reflective, but that seems optimistic to me ... :jointsmile:

i was walking into menards for something else and it caught my eye, its rather shiny i must say... Thats when it crossed my mind that it wouldnt be bad to use but i never researched it as far as reflectivity. also seems it would be easy to work with too and just cut and paste and your pretty much done especially in a cabinet grow..:thumbsup:. i am rather curious as to how good it is myself.
