We are announcing SilentShield

It is a fixed, transparent, sound-reflecting layer that is mounted inside the window on a hinge. This layer allows both air and light to pass through, but blocks disturbing noise. SilentShield is designed to remain closed and discreetly positioned in the corner of your window. When needed, SilentShield is opened, allowing the outer window to be opened, after which SilentShield is closed again. You are now ready to enjoy fresh air in peace and quiet.

The second advantage is that you get all the benefits of our full-size curtains, but at a fraction of the price.
