Get excellent insulation and sound reduction with Reach Air Double Reflective Insulation. It has two layers of sealed air laminated between two layers of durable reflective polyethylene. Reflective Air meets ASTM standards and complies with building code. It installs easily in attic spaces, exterior and interior walls, interior masonry walls, radiant floors, metal and steel buildings, knee walls, crawl spaces, garage ceilings and many other applications where insulation is needed. This insulation roll is 100 ft. long and 48 in. high. Reach Barrier reflective insulation products are one of the most versatile and energy efficient insulation products available. Radiant (reflective) barriers are installed in attics, walls, roof decking, and flooring.

Customer Questions & Answers

Will this help in an unheated attic?

We have a weekend cabin with an unheated attic. We have regular fiberglass insulation in the ceiling. and the attic floor is decked. It isn't high enough to use for anything other than storage, but it gets hot and we think maybe this would cut the air conditioning bill? So would we just staple it to the rafters? Would that create enough of an air pocket? Thanks!
Asked by: phatkhat
Dear PhatKat: Yes, this is an appropriate application for reflective insulation. In addition to stapling the plastic to the rafters, make sure the air pocket in each rafter bay is tightly sealed to prevent air leaks -- e.g. to block hot air flowing out from the edges or top. The 'Windows and Doors' version of Great Stuff foam works well for larger gaps; the cured foam remains flexible to block cracks as things expand and contract. DAP 230 sealant is best for smaller gaps. If you use your cabin in the winter, please be aware that reflective insulation is ineffective when it gets cold -- because cold cannot be 'reflected' and the warm air inside is not radiant. So if your cabin is also heated, it would be smart to install standard insulation in the attic instead of Reflectix. You could fill the rafter bays with Roxul ComfortBatt -- which provides R4 per inch, winter and summer. Then cover the rafters with Roxul ComfortBoard, to break the 'thermal bridge' created by the exposed wood, which is a surprisingly good conductor of heat and cold. Foam board is another alternative. You could install sheets of foam board on top of the rafters, e.g. TUFF-R Model # 268441, Home Depot Internet # 100322376 Store SKU # 163832. This product also has a foil faced radiant barrier on both sides, and provides R5 per inch. Carefully seal all of the edges and joints to block air leaks, just like Reflectix. Foam board is flammable, however, and must be covered by a thermal barrier in your attic. The standard is 1/2" drywall. So this would be an additional step not required with Roxul, which is fire-resistant. One more note: If you insulate the rafter deck, it would be a good idea to apply some insulation on all of gable end walls. I hope this is helpful. Mark

How to install?

Can I install this with liquid nails on our metal patio roof? If not liquid nails, please suggest best application.
Asked by: jlind
Dear JLind: All 'reflective insulation' products require you to build / create a sealed air pocket on one side, e.g. between your metal patio roof and the reflective barrier. This air pocket provides almost all of the claimed R value; the reflective plastic has almost no R value. So... if you glue it to your metal patio roof, this will eliminate any benefit. You would need to create an air gap between them. You could install 1x wood strips first, then fasten the reflective plastic to the wood. Make sure all of the seams and edges are sealed to block air leaks, e.g. with DAP Model # 18384 Home Depot Internet # 100134278 Store SKU # 284697 I hope this is helpful. Mark

Is this fireproof? Can I use it inside the enclosure around my oil burner to cut down the noise?

Asked by: MrsB
Dear MrsB: Definitely not! Reach is made from plastic with a maximum service temp of 180 degrees F. It would melt and catch fire if placed around your oil burner. In addition, if by "oil burner" you meant your oil-fired furnace or boiler, placing anything inside the enclosure could lead to overheated components and a fire. Never make changes to the design of a heating appliance like this. To reduce the noise from your furnace / boiler, you could add sound insulation to the walls of the room it is in. Roxul Safe 'n Sound, for example, is easy to install between wall studs and ceiling joists. See: Roxul Model # RXSS31525, Home Depot Internet #202531875 Store SKU #982937. A double layer of drywall also helps, mounted with a couple of tubes of DAP 230 sealant between each sheet -- to decouple the inner surface from the wall / ceiling structure. Also be sure to seal every air leak in/out of the room the furnace / boiler is in, because sound travels by air. I hope this is helpful, Mark

I removed plaster from walls in front hall. There is still the lathe left but no insulation. I want to apply blue board

What should I use for insulation?
Asked by: Dj
Dear DJ: 'Reflective insulation' products require you to build / create a sealed air pocket on one side. This air gap provides almost all of the insulation value; the reflective plastic provides almost no R value. Reflective products also do not work in winter because cold cannot be 'reflected'. So... there are a couple of good options for your exterior walls: (1) Blow in packed cellulose: With open lath on the walls, you could hire an insulation contractor to blow in "dense packed" cellulose that would fill the stud bays. This requires a high compression blower - not the kind that Home Depot rents to blow attic insulation. This is a popular solution for new construction and remodels like yours. (2) Install foam or rock wool board: Whether you install dense pack cellulose or not, add a layer of foam or rock wool board on top of the lath, before you install the blue board. Foam board provides R5 per inch and provides a good air seal, but is flammable. Rock wool board provides R4.2 per inch, reduces air flow and is not flammable. See: Owens Corning Foamular Model # 52DD, Home Depot Internet # 202085962 Store SKU # 307101 and Roxul ComfortBoard Model # RXCB11224 Home Depot Internet # 206789748 Store SKU # 1001748089 With both, seal all of the edges and joints to block air leaks; the 'Windows and Doors' version of Great Stuff foam works well; the cured foam remains flexible to prevent cracks as things expand and contract. I hope this is helpful. Mark

4 ft. x 100 ft. Air Double Reflective Polyethylene Insulation Roll is rated 4.2 out of 5 by 5.
Rated 2 out of 5 by from Arrived with 3" 'C' shaped gouge torn into it 5' from outer edge. Shipping Wrapping had a hole in it. This is dual insulation compared to the store's single layer version and a perforated under lining. It is light weight for my 2 season sunroom that was sold as a 4-season sunroom. Looks like the insulation layer used in Yerts (chinese round tents).

Rated 5 out of 5 by from it works The rolls are easy to move and they can be stapled. better to have another person help hold it up in place for the start point. I used duct tapeto start it, and to connect any spots the 3 inch overlap sagged on.
