Answer: 
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.

Answer: 
We do not recommend using the reflective one side/white one side material for wrapping metal duct. All of our testing for using Reflectix to wrap ductwork is for the double bubble product that is reflective on both sides.

Dear Adrian: Yes, but you cannot simply wrap it around the metal ducts. You must create a sealed air gap between the ducts and the layer of Reflectix. See the HVAC installation directions on the Reflectix website. Needless to say, creating this sealed air gap is not easy in tight spaces.

Home Depot sells fiberglass duct insulation that is easier to install and more effective -- particularly if you need to insulate a duct in a hot attic. You can simply wrap the duct with multiple layers to boost the R value. See: Model # INSWRP60, Home Depot Internet # 100152008 Store SKU # 363984 and Model # INSLV6, Home Depot Internet # 100396953 Store SKU # 363913.

Use foil HVAC tape to install duct wrap -- not silver fabric "duck" tape. See: Nashua Tape Model # 1207792, Home Depot Internet # 100030120 Store SKU # 915245.

Before you add insulation, make sure you carefully seal all air leaks. Mastic is the most effective solution; just apply a generous layer to every joint with your hand or a putty knife. See: Model # WBA50, Home Depot Internet # 100396973 Store SKU # 559722

I hope this is helpful.

Answer: 
This is a radiant barrier application. Install the product with the foil (shiny) side down. Radiant barriers are installed in open attics (typically ventilated) and do not require enclosed air spaces. This type of application reduces radiant heat transfer and is not quantified with an R-value.

Dear Customer: Yes, with a caveat: All 'reflective insulation' products require you to build / create a sealed air pocket on one side. This air gap provides almost all of the insulation "R" value. The plastic bubble wrap has almost no R value. So you would need to create a sealed air gap between your tin roof and the layer of Reflectix.

Depending on how this roof is constructed, Home Depot sells a number of alternatives that would be easier to install with more reliable results, e.g. Roxul Comfortboard.

Dear ARizonaHeat:
First, a few install notes and caveats:
(1) Reflective 'insulation' provides almost no value in winter because 'cold' cannot be reflected, and the warmth in heated air is not radiant -- like a hot metal roof in summer. Reflectix claims R7 with a cathedral ceiling in summer, for example, but only R1 in winter.
(2) Reflective insulation is only effective in summer if you build / create Read More

(2) Reflective insulation is only effective in summer if you build / create a sealed air pocket, e.g. between it and your metal walls. The edges must be air sealed, to block leaks and circulation.
(3) Performance degrades over time as dust accumulates on the shiny surface.
With all of this in mind, Home Depot sells other insulation products that will provide solid R value, winter and summer. For your metal utility building, Roxul rock wool board with foil facing would probably be best. This would provide the benefit of a reflective surface in summer, plus consistent R value in winter. Rock wool board is also non-flammable, unlike foam board which is very flammable -- often a key factor in a utility building. You can order it from your Home Depot's Customer Service or Pro Desk. Ask for Roxul Rockboard 60 with foil facing.
You could also add a layer of Roxul rock wool batts on the walls, with Rockboard or drywall on the inner surface. See: Home Depot model # RXCB351525 Internet # 202090820 Store SKU # 974419
Be sure to seal all of the Rockboard edges and joints to prevent air leaks. The 'Windows and Doors' version of Great Stuff works well; it remains flexible after it cures, to avoid cracks as things expand and contract.

Answer: 
The product should hold up well since it is on the interior of the building. The reflective side of the product will reflect 96% of the radiant heat back into the building.

Rated 5.0 out of 5.0 by Great product I am so glad i found this product..it is a nice easy to install vapor barrier for my 1926 basement walls.leave a fresh clean feel as well September 20, 2016
Rated 3.0 out of 5.0 by 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.

Rated 5.0 out of 5.0 by Great ceiling insulation Worked great to do garage ceiling. Easy and looks good June 7, 2016
Rated 4.0 out of 5.0 by Garage ceiling I insulated the garage ceiling with fiberglass batts and installed this to cover for a finished look. Easier than drywall and installed by myself. Stapled with white side down. Brightened the space December 30, 2014
Rated 5.0 out of 5.0 by Insulation Works great and is really easy to install. All you need is a box cutter and a straight edge and staples September 8, 2015
Rated 5.0 out of 5.0 by 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. January 29, 2013
