Sleep Panels

Blackout Your Windows for Better Sleep

Sleep Panels seal out light for total darkness and also block up to 50% of noise coming through windows* to create an ideal sleep environment. Unlike blackout curtains, shades or blinds, which allow some light around the borders, Indow Sleep Panel is edged in silicone compression tubing to create true blackout windows.

Indow window sleep panel insert AKA blackout panels.

This makes it a superior blackout solution for light sleepers or nurses, firefighters and others who work night shifts. Research has shown that good sleep is vital for your health and that it’s important to create a quiet, dark bedroom. For this reason, Indow Sleep Panels have also proven a hit with Paleo dieters.

Sleep Panels:

  • Custom made from medium density fiberboard (MDF) unlike our other grades, which are acrylic.

  • A white surface that can be painted or customized in other ways.

  • Installed in minutes. Each window opening is laser measured for a precise, snug fit.

  • Our lowest-priced grade.

Sometimes people will double up blackout curtains and shades or tack heavy blankets over their windows attempting to eliminate light. But it isn’t until they press in Indow blackout window inserts that they enjoy total darkness. If you’re sensitive to light, suffer migraines or need to sleep during the day, the Sleep Panel will create a dark, cool, quiet bedroom.
