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. ## Frequently Bought Together - SmartSHIELD -5mm 24''X50ft Reflective Insulation Roll, Foam Core Radiant Barrier, Heat-Cold Shield, Thermal Foil Insulation - Pure Aluminum - TapePlus Professional Grade Aluminum Foil Tape - 2 Inch by 210 Feet (70 Yards) - Perfect for HVAC, Sealing & Patching Hot & Cold Air Ducts, Metal Repair, and Much More - Romeda Aluminum Tape, 2 inch x 65 Feet Foil Tape (3.9 mil), Insulation Adhesive Metal Tape, High Temperature Heavy Duty HVAC Tape, Silver Tape Aluminum Foil Tape for Ductwork, Dryer Vent, HVAC --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/19157478-smartshield-5mm-24x50ft-reflective-insulation-roll-foam-core-radiant-barrier](https://www.desertcart.tw/products/19157478-smartshield-5mm-24x50ft-reflective-insulation-roll-foam-core-radiant-barrier) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-08*
