Customer Questions & Answers

i have a screened room with a tin roof. will this work putting it from the inside roof to keep room cooler

Asked by: customer
it may, if you apply it to the bottom of the roof trusses and have something like ridge venting to get the trapped hot air out. Don't think it would be real effective if you just form unvented hot-boxes.

Can this product be installed over faced insulation in a garage for appearance ?

Asked by: PRC
Dear PRC: NO! Reflectix is flammable and emits toxic gas when it burns -- just like foam board. It must be covered by an approved thermal barrier in any garage, living space, basement or attic storage area. The standard is 1/2" drywall. There are a number of options to improve the look of the walls and ceiling in your garage. Drywall is the most obvious, which also reduces fire hazards if the garage is attached to your home. If you need to do this job by yourself, you could rent or buy a drywall lift -- which makes placement much easier. See: Model # DPH11, Home Depot Internet #203900041 Taping drywall joints is actually not that difficult too. You probably won't create a completely smooth professional surface, and may have to sand more than a pro would, but that's OK. Another option is Roxul Rockboard 60, which is available with white poly or foil facing. This would not provide the finished look of drywall, but would be much nicer than exposed insulation! Look it up on the Roxul website. You can order it from the Home Depot Pro Desk, ask for "Roxul Rockboard 60" and specify the facing you prefer. This product is used as the final surface in commercial parking garages, etc. I hope this is helpful. Mark

Can I use this to insulate round sheet metal ductwork?

Asked by: Adrian
Thank you for your question. Yes, insulating your HVAC ducts is an excellent application. The BP48025 is the recommended product. Directly wrapping with taped seams nets an R-4.2 or incorporating a nominal 0.625" air space (the product cut into a 2" wide strips wrapped twice around the duct on 24" intervals) will net an R-6.0.

48 in. x 100 ft. White Single Reflective Insulation is rated 4.6 out of 5 by 8.
Rated 5 out of 5 by from I installed Reflectix White Single Reflective Insulation on the wall... I installed Reflectix White Single Reflective Insulation on the wall studs of my roll-off roof observatory. The intent is to reduce heat intrusion and prevent the observatory from getting hot enough to damage equipment. I also installed Reflectix radiant barrier under the metal roof. It, along with a small gable-end exhaust fan, has successfully kept observatory temperatures below 100 degrees. The building had been an oven, 120 degrees or more, before installing radiant barrier and I had to keep equipment in my house. I used to feel the heat radiating from walls and roof. No more. Great stuff!

Rated 5 out of 5 by from Effective and easy to work with My basement has a stone foundation that is drafty and constantly sheds sand from the old mortar. It's not worth finishing properly but I wanted to make it useable for a workshop without investing too much time or money. The reflective insulation works perfectly for this, it was cheap and easy to hang up. The basement is noticeably warmer and less damp feeling now and the white outer surface dramatically brightened it up. I have no complaints about this stuff, it's light and easy to work but is tough enough to not accidentally rip.

Rated 3 out of 5 by from Great product, poor handling from HD Very good product. Excellent for the ceiling of my pole barn. Handing of the material was TERRIBLE though. One box was battered and torn, and then taped back together. I haven't opened it yet to check for damage. Previous shipments of this material were fine. Not sure what went wrong this time.
