Tlany Window Insulation Kit for Winter 27x39 – Thermal Curtain with Heavy Cotton

Overview

Keep cold drafts at bay with the Tlany Window Insulation Kit, sized at 27 by 39 inches. This thermal curtain blends a windproof outer layer with thick cotton padding to form a reliable barrier against chilly air and moisture, helping maintain a comfortable indoor feel during the cold season.

Designed for versatility, this kit works well as a standalone cover or layered with your existing curtains. It’s crafted to balance warmth with a clean, unobtrusive look that fits many window styles in homes, RVs, and basements.

Design and Materials

The kit features a multi-layer construction: a durable windproof Oxford outer shell, a robust 180 g cotton filling, and an interior seam system that keeps the insulation in place. An additional waterproof outer layer adds protection against rain and moisture, while ultrasonic stitching prevents shifting or clumping of the filling over time.

• Windproof Oxford fabric acts as a strong cold-weather barrier
• 180 g cotton padding provides substantial insulation with ongoing comfort
• Multi-layer design locks warmth in while resisting moisture
• Ultrasonic stitching keeps the filler evenly distributed
• Waterproof exterior adds moisture resistance without sacrificing style

Installation and Fit

Installation is straightforward thanks to the included adhesive hook-and-loop strips, designed to stick to a wide range of surfaces. A 1.5-inch fastening width helps stabilize the cover for a secure fit. The curtain measures 27 inches wide by 39 inches long and is best suited for windows up to 24 by 36 inches. Two black buckles are included for simple roll-up storage, so you can open your window without fully removing the curtain.

Versatility and Practical Use

This insulation kit serves both warming and cooling needs. Use it to reduce drafts in winter and minimize heat transfer in warmer months. It pairs well with your existing window treatments and adapts to settings such as living rooms, bedrooms, kitchens, RVs, skylights, and basements. The design supports flexible placement and reusability across seasons.

• Measure your window to confirm a snug fit; smaller openings can be accommodated with simple adjustments
