Installation instructions

1. Remove the sheer curtain and lay it flat with the back side facing you.

2. Take the self-adhesive hook-and-loop tape and position it just below the sheer curtain heading (on the back side). Stick the tape across the entire width of the sheer curtain, starting from one end. Gradually remove the protective backing as you go. Depending on your sheer curtain fabric, the adhesive on our hook-and-loop tape may not be sufficient. We recommend adding a few stitches to reinforce the fastening system and ensure the lining remains securely attached.

3. Attach the hook-and-loop strip on the lining to the tape you have just fixed onto the sheer curtain.

4. Hang the sheer curtain on your curtain rod or track (not included).

Inspired by the principle of emergency blankets, the patented THERMACTIV® technology incorporates a highly reflective metallised layer. By reflecting infrared radiation, it acts on heat transfer between indoors and outdoors, helping to limit heat loss in winter and heat gain in summer. A technology developed to effectively complement home insulation.

Frequently asked questions

Our thermal linings attach to the back of your existing curtains to give them the performance of patented THERMACTIV® technology. This improves your thermal comfort without changing your curtains or your décor.

A thermal curtain is a technical curtain designed to limit heat transfer at windows. It helps to retain warmth in winter and keep your home cool in summer, improving your comfort and reducing your heating and air conditioning needs. At Moondream, our thermal curtains feature THERMACTIV®, a patented technology with a micro-metallised layer that reflects thermal radiation.

Our thermal linings and thermal curtains feature THERMACTIV®, a patented technology designed to limit heat transfer at windows, in both winter and summer.

Inspired by the principle of an emergency blanket, this technology relies on a highly reflective micro-metallised layer. Its effectiveness depends not on the thickness of the fabric, but on its ability to reflect thermal radiation:

  • In winter, it reflects heat back into the room, limiting heat loss.
  • In summer, it reflects thermal radiation coming from outside, helping to limit the rise in indoor temperature.

The thermal performance stated on each product page has been measured and validated by independent laboratories with the product used in this configuration.

Available as a lining to add to your curtains or already integrated into our thermal curtains, THERMACTIV® improves your comfort all year round, without building work or compromising your décor.

Yes. To adjust the length of your curtain, we recommend our height alteration service. This service ensures a neat finish while preserving the curtain's technical construction.

If you need specific dimensions, you can also order a made to measure curtain.

If you prefer to make this alteration yourself, first hang your curtain and pin the hem at the desired height.

The lining is deliberately a few centimetres shorter than the face fabric. Iron-on hemming tape must be applied only to the face fabric, never to the lining.

If you need to shorten the curtain by more than this difference, there are two options:

  • Make the hem using iron-on hemming tape: trim the lining so that it remains slightly shorter than the face fabric, then hem only the face fabric, following the video tutorial on our YouTube page.
  • Have a sewn hem made: have each layer shortened and hemmed separately, keeping the bottom of the curtain open. The different layers must not be sewn together. We recommend having this work carried out by a professional.

To maintain heating efficiency, position your curtain so that heat can circulate freely around the room. A thermal curtain placed in front of a radiator may trap heat between the fabric and the wall.

Avoid any direct contact between the curtain and the radiator, and observe the safety distances specified by the manufacturer of your appliance.

No. Install your curtain or thermal sheer just as you receive it: there is no need to adjust the lining between winter and summer.
