Review: Reflective Barrier - great product - I purchased this product to cover an aluminum firewall. It has a nice appearance and is easy to work with. After seeing the prices of what is being sold in the automotive market such as sound deadening products I knew their were alternatives to being gouged by the brand name sellers. This should do fine & I have a 2 foot by 50 foot roll of material that I can use for other projects. I did a quick test to see how well it held up to heat by blasting it with my Porter Cable heat gun. With it on the highest settings , holding it a couple of inches away from an edge I was glad to see it didn't burst into flames nor did it shrivel up into a ball or even shrink . It retained it's shape although it did flatten out - loosing it's "puffiness" so rather than having two thicknesses of material with an air space in-between , it's more like a thicker flatter piece. LOL! It is about the same as the edges that you would staple through to attach it to 2 x 4 wall studs etc. I will use a spray adhesive to attach it to the firewall . It's a good product. It arrived within a couple of days , being a Prime customer I had to overlook the shipping and viewed it as just the price of the product. So for about fifty bucks I ended up with 3 or 4 times the amount of material I would have had . If you want to spend a lot of money you could check Eastwood , Sound Buddy's and others. I'd buy this product again , but I still have a lot more to use . I will probably start with the garage door , next up the shed . . . . . then the . . . . . Buy it , you will be glad you did. Don Review: Works better than expected - I bought this to wrap an inexpensive greenhouse that lives on our patio. We tried everything we could but it didn’t stay warm enough. As soon as I wrapped it in this the temperature went up ten degrees. We’re now able to maintain 65 degrees even in 34 degree weather. We have a very small low wattage space heater in there to help maintain the heat and it’s hooked up to a thermostat. We also have a grow light. The wrap is open in the middle of the front so I can get into the greenhouse and overlaps the openings of the actual greenhouse cover. I wanted to let oxygen flow some while allowing little heat to escape. Our system is hydroponic and the water has a weak heater that couldn’t keep up in cold temps. Very excited to grow happy fresh vegatables in the winter. ## Features - EXTREMELY EFFECTIVE - reflect 97% of radiant energy, perfect RADIANT BARRIER. - VAPOR BARRIER - Unaffected by humidity and moisture, can be used outdoor/indoor. - SOUND BARRIER - excellent soundproofing material. - SUPREME QUALITY - 3mm closed cell polyethylene FOAM (not a cheap bubbles) sandwiched between PURE ALUMINUM foil on both sides. Easy to install, easy to cut and easy to clean, 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 | B01BDWY8ZG | | Best Sellers Rank | #602,179 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #359 in Weatherproofing Window Insulation Kits | | Brand Name | INSULATION MARKETPLACE | | Coverage | thermal protection | | Customer Reviews | 4.5 4.5 out of 5 stars (264) | | Item Dimensions L x W | 600"L x 24"W | | Item Thickness | 3 Millimeters | | Manufacturer | InsulationMarketPlace.com | | Material Type | Polyethylene (PE) | | Recommended Uses For Product | Attics, ceilings, walls, steel buildings, roofing, concrete floor, radiant heat in a heating under wood cathedral ceiling, water heater tank, radon barrier, pipe and air duct, reflective ceiling system, behind hot radiator, crawl space, in-ground swimming pools, shed, fish & hunting shelter, cooling room, cold chamber or wine cellar, block wall, cavity wall for metallic studs commercial foundation… | ## Product Details - **Brand:** INSULATION MARKETPLACE - **Item Thickness:** 3 Millimeters - **Material:** Polyethylene (PE) - **Product Dimensions:** 600"L x 24"W ## Images ![SmartSHIELD -3mm 24"x50Ft Reflective Insulation roll, Foam Core Radiant Barrier, Thermal Insulation Shield, Commercial Grade (24"x50') - Image 1](https://m.media-amazon.com/images/I/91NWfYNN4XL.jpg) ## Questions & Answers **Q: Can you cut it lengthwise?** A: You can cut this insulation any direction you'd like to cut it. I use this insulation in cars and trucks to keep heat and noise down (mostly heat). It cuts very easily with a knife or scissors...use a quality tape to seal the edges (I use gorilla tape or aluminum tape) just to make sure it last for many years. This insulation is very good at most things...I've tested it with my heat gun and it held up even better than expected. It's fabricated very well and does allow cutting to shape with ease. My air conditioner and heater in my personal truck are amazingly efficient and requires much less effort to keep the temp right where I set it (I live in the San Antonio Texas area...it's hot down here). **Q: "works ideal in hot or cold climates", someone said r value is r16. is that for the 3mm? is it really good at keeping the cold out? thanks 4 reply** A: I have applied this material to my roll up overhead doors in my shop and it does a nice job of keeping the cold in the winter and reflective heat in the summer from penetrating the aluminum doors. **Q: whats he heat rating? whats duration of resistance?** A: It says R20 **Q: I need an additional ceiling, for example drywall or pvc ceilings? What percentage lowers the temperature this material? For 80 sqmts how many rolls?** A: It is not the intended purpose, you need to purchase fiberglass insulation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reflective Barrier - great product *by D***H on May 8, 2016* I purchased this product to cover an aluminum firewall.

It is a bit thinner than I expected, but has the advantage of being very easy to cut with scissors and to bend, while being stiff enough to stay straight and stand upright if that is what you want. It is also super lightweight. I live in the SF bay area in California and sun on my planters on my paved patio can be brutal in the summer, baking the roots of plants. I found that the plants in my fiberglass planters that face south dried out super fast, and I think it is just the heat of the sun hitting them. So I am going to try lining the inside of the planters with this, to reflect the heat back out, and then fill them with potting soil. Between the reflective foil and the thin layer of foam, that should help. But I won't know until this summer. However, I am happy with this product--I think it will be very easy to work with and easy to line the planters with. I also think it could be a great product for reflecting heat that comes through a wall, where you have limited space to insulate. We are thinking of using it behind our medicine cabinet which is recessed into an exterior 2x4 stud wall that gets morning sun and gets very warm in summer. If we were putting in a new medicine cabinet, we would definitely try using a product like this, or maybe the foil-bubble-foil type, to provide some protection from heat. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/35189590-smartshield-3mm-24x50ft-reflective-insulation-roll-foam-core-radiant-barrier](https://www.desertcart.hr/products/35189590-smartshield-3mm-24x50ft-reflective-insulation-roll-foam-core-radiant-barrier) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
