Lo compré principalmente para que uno de mis perros no sufra con el calor (es pastor alemán), y si he notado como pasa mejor noche. ### ⭐⭐⭐⭐⭐ Good Quality product *by B***T on 22 December 2022* Easy to cut into the required lengths. Have used it on the inside of a garden shed but will have to wait till next week when the temp will be in the high 30's to see if it helps.. was delivered before due date. ### ⭐⭐⭐⭐⭐ What a difference *by M***Y on 4 July 2023* The amount of heat this keeps out is really amazing. Old house, old windows, poor insulation.... During the 'dog days' of summer even with the AC running non stop, it would get fairly warm then cool off as the sun set. I did some research and put some pipe insulation over the AC exhaust (portable) and grabbed a roll of this stuff after reviewing most of the brands available here this one seemed legit and the right size I needed as well. Glad I did. Now, there's a heat warning and it's noticably cool upstairs. Not like before. This stuff works! ## Frequently Bought Together - INSULATION MARKETPLACE SmartSHIELD -3mm 16inx50Ft ReflectiveINSULATION roll, Foam Core Radiant Barrier, ThermalINSULATION Shield - Engineered Foil - Aluminum Foil Tape, 2 inch x 65 Feet (3.9 mil), Insulation Adhesive Metal High Temperature Heavy Duty HVAC Tape, Silver for Ductwork, Dryer Vent, HVAC - XFasten Transparent Window Weather Sealing Tape, 2-Inch x 30 Yards (50.8mm x 27.43m), Clear Window Draft Isolation Sealing Film Tape, No Residue --- ## 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.com.br/products/387213233-smartshield-3mm-16inx50ft-reflectiveinsulation-roll-foam-core-radiant-barrier-thermalinsulation](https://www.desertcart.com.br/products/387213233-smartshield-3mm-16inx50ft-reflectiveinsulation-roll-foam-core-radiant-barrier-thermalinsulation) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-15*
