Main highlights- Wide Application: The reflective insulation roll is highly versatile. It can be used in many indoor and outdoor places such as windows, attics, garages, sheds, RVs, greenhouses, and cars. By reducing heat transfer, it not only helps you stay comfortable but also saves you energy and money on heating and cooling bills.
- Warm Tips: Please note that due to transportation constraints, the thermal insulation foil may arrive with some creases as it's folded during packaging.

- Package Contents: HADOR Reflective Window Insulation kit has everything you need. It includes a 48 inch x 10 foot insulation foil, suitable for most windows. It comes with 65 small round hook and loop adhesive pads to ensure a secure fit, along with a roll of heavy duty aluminum foil tape for extra strong fixation.
- Easy Installation: Installing our window insulation is a breeze. All you need is a utility knife or a pair of scissors to cut it to the perfect size for your window, garage door, or any other area you want to insulate. Simply attach it using the provided accessories, and you're done.
- Durable Quality: HADOR RV window insulation has a three layer structure, with aluminum foil on both sides and 3mm polyethylene foamed cotton in the middle. The foil surface design boosts heat reflectivity, offers sun protection, waterproofing, and thermal insulation. Built to last, you can rely on it for years to come.
- All Season Comfort Maintenance: Our reflective insulation board, with a foam core between double aluminum foil, offers great thermal insulation. It effectively blocks the sun's rays in summer, keeps out the sweltering heat, and in winter, it prevents heat loss, ensuring your home stays cozy and warm.
