Indow offers three window light-blocking solutions to help you reduce air conditioning bills, gain privacy, or create darkness for better sleep. Our custom-made inserts fit windows using silicone compression tubing so they press into place without mounting hardware.
There are many unique challenges when it comes to controlling light. Indow inserts create custom window sun protection and window privacy solutions without having to replace your windows, add blinds, or hang curtains.
Sleep Panels block out all light for 100% darkness.
Museum Grade blocks 98% UV rays and increases energy efficiency .
Privacy Grade diffuses light for privacy without blocking natural light.

Like all our inserts, each of our window light-blocking solutions add energy efficiency and reduce noise. In addition to protecting your furniture or providing privacy, Indow inserts will also:
- Reduce 50% of outside noise.*
- Increase comfort by eliminating drafts.
- Lower heating & cooling bills up to 20%.
- Install & remove easily.
Sleep Panel – Blackout window inserts provide 100% darkness and 50% noise reduction. Because of their snug fit, these panels block out ALL LIGHT, no creeping rays around the edges. The panels are made of medium density fiberboard with a white surface facing the inside of the room. This material also helps control room temperature. They install and uninstall in minutes with easy storage under the bed.
Museum Grade – UV window protection prevents fading on wood floors, furniture, & artwork. These inserts block 98% of UV rays while allowing natural light through. They offer the same noise reduction and temperature control as the Sleep Panel. With UV protection for windows, you are protecting your other home investments.
Privacy Grade – Window privacy inserts that still allow natural light. These inserts are translucent, so block the view coming through the window, but allow light to fill the room. The surface of the insert is “clouded” which hides fingerprints and the compression seal helps reduce condensation (easy bathroom cleaning). They offer the same noise reduction and temperature control as the Sleep Panel.
*We want to ensure our inserts help solve your noise problem. Overall noise reduction depends on the amount of noise coming through your walls, ceilings, floors, doors, and existing windows. Noise reduction will be less when placed over double-pane windows. Read our full Noise Reduction Sheet to learn more.
Consider the cost and disruption of replacing your windows. A vinyl window averages $66-$87/sf. A wood window averages $71-$109/sf. With Indow inserts averaging between $31-$44/sf MSRP, your window project can cost a fraction of other options.
