Review: Foil could be better - Bought a different brand a year ago but this one recently. It’s not as good in quality as my first one but it works. I find the foiling to be thinner and therefore not smooth. Lots of wrinkles etc. it also has excess foiling on the end which is not needed and I have to tuck it under. Next time I’ll buy the other brand again. Review: Good addition, minimal effort. - I am using this for a bathroom remodel. The original fiberglass wall insulation was insufficient on this cold, northwest corner of the house, but this will be a huge improvement. It is easy to work with and cut, and the minimal thickness adds a decent R-value AND radiant factor. ## Features - EXTREMELY EFFECTIVE - Reflect 97% of radiant energy, perfect RADIANT BARRIER. R-value up to 15.67 ( with one layer), up to 21.10 ( with two layers). - VAPOR BARRIER - prevents condensation, unaffected by humidity and moisture. - SOUND BARRIER - excellent sound deadener material. - SUPREME QUALITY - 5 mm closed cell polyethylene FOAM (not a cheap bubbles) sandwiched between PURE ALUMINUM on both sides. Easy to install, easy to cut. Strong but lightweight. - FIRE RATE - Fire rate Class 1 / Class A, NON TOXIC - will not irritate skin, eye or throat. Non allergic. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ZNKHUN2 | | Best Sellers Rank | #102,340 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #23 in Panel Insulation | | Brand | INSULATION MARKETPLACE | | Brand Name | INSULATION MARKETPLACE | | Coverage | [Wide] | | Customer Reviews | 4.6 out of 5 stars 739 Reviews | | Item Dimensions L x W | 15.24L x 0.41W Meters | | Item Thickness | 5 Millimeters | | Item thickness | 5 Millimeters | | Manufacturer | INSULATION MARKETPLACE | | Material | Polyethylene (PE) | | Material Type | Polyethylene (PE) | | Model Number | SmartSHIELD -5 | | Product dimensions | 15.24L x 0.41W Meters | | Recommended Uses For Product | Attics, Ceilings, Walls, Steel Buildings, Roofing, Concrete Floors, Radiant Heat in a Concrete Floor, Radiant Heating Under a Wood Floor, Cathedral Ceiling, Water Heater Tank, Radon Barrier, Water Pipe and Air Duct, Reflective Ceiling System, Behind a Hot Water Radiator, Crawl Space, In Ground Swimming Pools, Shed, Fish & Hunting Shelter, Cooling Room, Cold Chamber or Wine Cellar, Concrete Block W… | | Recommended uses for product | Attics, Ceilings, Walls, Steel Buildings, Roofing, Concrete Floors, Radiant Heat in a Concrete Floor, Radiant Heating Under a Wood Floor, Cathedral Ceiling, Water Heater Tank, Radon Barrier, Water Pipe and Air Duct, Reflective Ceiling System, Behind a Hot Water Radiator, Crawl Space, In Ground Swimming Pools, Shed, Fish & Hunting Shelter, Cooling Room, Cold Chamber or Wine Cellar, Concrete Block Wall, Cavity Wall for Metallic Studs in Commercial Buildings, Foundation Wall, Above Ground Swimming Pools, Quanset Hut, House Wrap.

Thanks** A: Yes. Before the insulation is glued be certain that the glued area is clean and dry. We used this insulation glued to the fiberglass top of a cargo van to reduce heat transfer. The inside of the cargo area stays some what cooler in the summer and slightly warmer in the winter keeping the cargo at better temperatures then outside. **Q: Is it durable to attach/reattach to an RV to block the hot texas sun?** A: I cut to fit my RV windows wrapped edges of this with gorilla tape super glued velcro on it and other side of velcro in my window groove all the way around so its sealed. Keeps heat out keeps heat in the winter windows don't freeze up. Time consuming yes but what else was I gonna do with my time **Q: Is this product rodent resistant?** A: No matter what anyone says..... nothing is rodent resist. Resistance is futile **Q: May I use this on RV windows?** A: This is best type of insulation for RV windows. It will reflect 97% of radiant heat, plus have a great resistance to conductive flow of heat. AD-5 reflective insulation will stop both Conductive and Radiant flow of heat, also good sound barrier. ## Customer Reviews ### ⭐⭐⭐ Foil could be better *by M***A on 22 December 2023* Bought a different brand a year ago but this one recently.
