About This

Window Insulation Cover Kit for Winter - Our weatherproofing window insulation kit for winterizing includes one 47" x 35" insulating magnetic window cover, a 0.75 ft wide self-adhesive velcro tape, and a box of 20 nails. Seal around your windows to prevent heat loss, save on energy costs, and keep your home warmer during winter. Ideal for use in house living rooms, bedrooms, attics, basement, and more. Warm tip: Measure both the width and height of your window and choose the appropriate size.
3-Layer Insulation - Our heavy duty window cover features a 3-layer composite design. The outer layer is made of premium waterproof Oxford fabric, offering excellent water resistance and protection against wind and dust. The middle layer is filled with high-quality cotton, providing insulation and a soft, fluffy texture. The thickened structure blocks cold air from seeping through window gaps, maintaining indoor warmth while creating a quiet, darkened space for better sleep quality.
Transparent Window Design- The large visible insulated window coverings features a specially designed transparent viewing window made of high-transparency material. It preserves excellent insulation while allowing you to clearly see outside without removing the heavy curtain or adjusting drapes. Whether enjoying winter snow scenes or observing people and cars outside, visibility is effortless. Meanwhile, it lets natural light flow indoors, creating a bright and comfortable living environment.
Flexible Roll-up Design - The thermal curtain of the window cover blanket wrap features a convenient roll-up design with two fastening straps at the top, allowing you to easily roll it up and secure it without removing the entire cover. This design lets you open the window anytime for ventilation or to enjoy the view, while the self-adhesive tapes on both sides stick together easily to form a tight seal, effectively preventing heat loss and enhancing warmth while maintaining flexibility of use.
Easy to Install & Remove - Our reusable winterize window insulation sealer can be installed without any complex tools—everything you need is included in the kit. Simply attach the self-adhesive tape around the window frame, then align and secure the curtain using the built-in Velcro. For extra stability, you can reinforce the edges with the included nails. When not in use, gently heat the adhesive area with a hair dryer to remove it easily. Both installation and removal are quick and convenient.
