Thermal & Insulating Curtains

NOKOMIS thermal curtains are technical curtains designed to improve comfort near windows, picture windows, and doors. Their fabric construction helps limit heat transfer around openings and reduces the sensation of cold walls in winter or heat-related discomfort in summer.

According to our validated data, the Performance PLUS model can contribute to a temperature gain of 6 to 8 °C, depending on the installation and the window's configuration.

Depending on the model, they also combine light blocking and heat noise reduction. Performance depends on the chosen curtain, its dimensions, the overlap around the opening, and the installation. A thermal curtain complements a home’s insulation but does not replace the building’s structural insulation.

Winter/Summer Comfort

Thermal-insulating curtain: improving comfort near windows

A thermal-insulating curtain adds an additional fabric barrier in front of a window, a picture window, or a door. It helps limit heat transfer through the opening and reduces the sensation of a cold wall in winter or heat-related discomfort in summer.

The result depends on the model chosen, the actual surface area covered, and the gaps left around the curtain. A thermal curtain complements a home’s insulation: it does not replace insulation in the windows, door frames, or walls.

A result that also depends on the installation

Proper sizing and installation make a real difference

To improve comfort, the curtain should cover the opening generously. The right drop length and sufficient overhang on the sides and top minimize uncovered areas around the window.

Depending on the model, NOKOMIS offers eyelet or Gathering tape finishes for installation on Curtain pole or Track. The right choice depends on your window and the layout of the room.

Choose Based on Your Needs

Which “ thermal curtain ” should you choose?

To keep out the cold in winter: Choose a blanket that generously covers the window, and install it in a way that minimizes open areas around the fabric.

To combat summer heat: closing the curtain when sunlight becomes intense adds an additional fabric barrier in front of the window.

To combine thermal comfort and noise reduction : the Performance and Performance PLUS models offer a range of features. Performance levels and specifications vary by model; please refer to the corresponding product sheet before making your selection.

For custom dimensions: use our custom configurator to adjust the width, height, and finish to fit your opening.

What You Should Know Before Buying

Additional insulation, not a structural renovation

A window seal ( thermal curtain ) can improve comfort around an opening, but it does not make a window airtight and does not compensate for poor building insulation.

If you feel a strong draft, first check the condition of the seals, the window and door frames, and—if present—the roller shutter box. The curtain then acts as an additional fabric barrier.
