Live in a cold climate and really helps keep out the cold and save on energy. It is easy to cut to fit. Has adhesive tabs for ease of use for sticking directly to window. We personally cut to fit the whole window and frame so that we press into the whole window to fill in all gaps. It definitely gives a fuller coverage of any air leaking in or out. We duck taped remnant pieces to other pieces to create the size needed with no waist. The thickness is perfect. Not to thick that it won’t shape to window and frames but it is thick enough that you can’t feel the weather through the windows. This item has definitely helped with staying warm through the extremely cold weather recently. Review: Really helps RV windows in extreme weather - Excellent product. We live in an RV and we all know how well they’re insulated. Wink Wink. I cut out sizes to cover every window and mark each cut as to which window it’s for (trust me, it will save time and frustration later). When the weather is going to be freezing or below for any period of time I just raise the window shade, slide the cut out in and lower the shade. It stays in place with no adhesive or tape. When it warms up, raise shade and roll up cut outs together. We can attest that it does make a big difference. ## Features - 【SAFETY MATERIAL】✅ MRPAPA reflective insulation sheet is made of truly double Aluminum foil and polyethylene bubble.

Did keep the temoerature down some. Found out after return in the fall that adhesive on the velcro had melted. Will use again next year, but will put them on the outside between windows and sun screens and not use the velcro. ## Frequently Bought Together - Double Reflective Insulation Foam, 48" x 10 Ft Reflective Window Insulation Radiant Barrier, Aluminum Foil Bubble Insulation Roll for Keep Heat, Thermal Insulation 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 - Reflectix BP24025 24-Inch by 25-Feet Bubble Pack Insulation, 1-Unit --- ## 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.hk/products/563424996-double-reflective-insulation-foam-48-x-10-ft-reflective-window](https://www.desertcart.hk/products/563424996-double-reflective-insulation-foam-48-x-10-ft-reflective-window) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-28*
