Real product evidence

Watch the room change—and see what affects the result.

These demonstrations show actual Dawnproof products in use. They are not laboratory certification, and they do not promise an identical result in every room.

Dawnproof Fixed

Fitted perimeter. Manual movement.

The shade closes inside its frame to help manage edge light. The opening, submitted measurements and installation all affect the finished result.

Dawnproof Anywhere

Portable coverage. No drilling.

The two-layer panel covers the submitted area with hook-and-loop fastening. Measurement, placement, surface condition and edge coverage affect darkness.

What Dawnproof provides

Purpose-built light control.

  • Fixed: continuous honeycomb shade and fitted perimeter
  • Anywhere: two-layer blackout panel and hook-and-loop fastening
  • Made-to-order sizing based on the measurements submitted

What the room still controls

Fit conditions matter.

  • Window shape, trim, handles, locks and screens
  • Measurement accuracy and installation or placement
  • Surface condition and how closely the edges are covered
