Soundproofing & Protection from Indow, for Less


Indow window inserts reduce noise, block damaging UV rays, block drafts, and lower your cooling and heating bills to give you year-round savings. Our four Premium Grade inserts are now 10% off.

Acoustic Grade

Acoustic Grade is the ultimate when it comes to soundproofing, blocking up to 70% of outside noise when used with operable single-pane windows*. When used with operable double-pane windows, they reduce more than 50% of outside noise. Got a noise issue? Acoustic Grade is the insert for you.


From The New Yorker Is Noise Pollution The Next Big Public Health Crisis?

“Modern sound-related health threats extend far beyond music, and they affect more than hearing. Studies have shown that people who live or work in loud environments are particularly susceptible to many alarming problems, including heart disease, high blood pressure, low birth weight, and all the physical, cognitive, and emotional issues that arise from being too distracted to focus on complex tasks and from never getting enough sleep.”

Museum Grade

Museum Grade is ideal for blocking harmful UV rays from coming through your windows. UV radiation found in sunlight causes serious fade damage to furniture, wood floors, and artwork. Museum Grade blocks 98% of UV rays. Scott Sidler of The Craftsman Blog says:

“To use Museum Grade, where you can extend the life of the floors another 10-15 years between re-finishings, financially it makes a lot of sense.”


Shade Grade

is like sunglasses for your windows to keep your home cool in the summer. They let in light while blocking excess heat.

Privacy Grade

adds an opaque finishing without damaging the original glazing of your windows. You maintain privacy while enjoying plenty of light.

*Note, overall noise reduction performance depends on how much noise is coming through walls, ceilings, floor, and doors. The window noise reduction will be less when Indow inserts are placed over double-pane windows. We do not recommend Indow inserts for reducing noise coming through laminated glass windows, triple-pane windows or hurricane windows.
