Thermal curtain panel – a dense weave that keeps afternoon heat on the other side of the glass

This curtain panel is woven tightly enough to stop direct sunlight at the window instead of letting it land on your floor. The same density means nobody sees in once the lamps go on. Seven panel sizes run from 80 × 100 cm up to 120 × 120 cm.

Why choose this curtain panel?

A west-facing room climbs all afternoon and holds that heat well into the evening. Catching the sun at the glass is far more effective than cooling the room afterward. A heavy panel also hangs straight, so it stays in place with the window cracked open.

Dense weave: blocks direct sun and slows the warm-up in the room behind it.
Room-darkening: useful over a bed or behind a monitor, where reflections get in the way.
Privacy after dark: the room stays dark from the street even with the lights on.
Seven panel sizes: from a narrow kitchen window to a wide patio door.
Heavy drape: the fabric falls flat and does not billow in a breeze.

The result is a window that stops being the warmest spot in the room.

Measure the width of your rod and add about a third, so the panel still gathers when it is closed. Hang it as close to the glass as the fitting allows, since that is where the heat gain happens. Fold creases drop out on their own within a day of hanging.
