Introducing Dawnproof Fixed

A darker room starts at the edges.

A fitted perimeter helps manage the light ordinary curtains leave behind, while an insulating honeycomb shade slides aside when you want the window back.

How Fixed works

Four parts. One clear purpose.

The perimeter, shade, moving rail and side stack work together so coverage and everyday window access are part of the same design.

Darkness for the hours you keep

Make the room answer to your clock.

Whether rest starts after sunrise or between the day’s routines, Fixed lets the opening move from covered to accessible again.
