It is very effective, very light, thinner than the bubble types, and can be used in many ways. I use it as windshield covers, either inside or outside, for our car and I even use it for a very effective insole and canting shim for my ski and snowboarding boots. **Q: Would this insulation work on the bottom inside of a greenhouse window?** A: It reflects the sun away , it's very very thin . If that is what you are trying to do is reflects the sun out then it may work ## Frequently Bought Together - INSULATION MARKETPLACE SmartSHIELD -3mm 16inx10Ft ReflectiveINSULATION roll, Foam Core Radiant Barrier, ThermalINSULATION Shield - Engineered Foil - K&H PET PRODUCTS Self-Warming Cat Bed Pad, Self Heating Pad for Outdoor Cat Houses, Warming Mat for Indoor Pet Beds & Furniture, Reversible Blanket, Machine Washable - Small 21 X 17in Gray/ Black - TRIXIE Outdoor Cat House, Weatherproof Cat House with Raised Floor, Hinged Asphalt Roof & Covered Opening, Small Outdoor Shelter for Cats and Small Animals, Gray & White Fir Wood --- ## 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.pt/products/415088756-smartshield-3mm-16inx10ft-reflectiveinsulation-roll-foam-core-radiant-barrier-thermalinsulation](https://www.desertcart.pt/products/415088756-smartshield-3mm-16inx10ft-reflectiveinsulation-roll-foam-core-radiant-barrier-thermalinsulation) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-22*
