What is a Standard Grade Interior Storm Window Insert?

Indow’s Standard Grade interior storm window inserts are an innovative, cost-effective way to block drafts and noise to make your home comfortable and energy efficient. We designed these inserts to help your existing windows perform like new double-panes all the while blending into the frames so they’re nearly invisible. They install in seconds without disruption or mess.

Unlike conventional interior storm windows, these window inserts press inside your existing window frames without a damaging mounting bracket. Save money on energy bills while keeping your original windows to preserve your home’s character and value.

 

Standard grade custom storm window inserts:

  • Nominal ⅛” thick acrylic glazing.
  • Edged in Indow’s patented silicone compression tubing.
  • Made in three different colors - warm white, brown and black.
  • Available in custom shapes like arches and rounds.
 

How Custom Storm Window Inserts Work

Because houses settle, most windows aren’t square. At Indow, we laser measure every window opening and then custom make each insert, ensuring a precise, snug fit for an airtight seal that blocks drafts. That compression is also what holds the insert in place.

The inserts blend in and can’t be seen from the exterior of the house, so don’t violate historic district guidelines. People with newer double-pane windows use Indow inserts to enhance their performance.

Standard Grade inserts are suitable for any room. Some homeowners start by installing inserts in their draftiest space and over time buy inserts for the rest of their home.

 
 

Testimonials on Custom Storm Window Inserts

Instead of replacing the historic windows in his home, Kester installed Indow Standard Grade interior storm window inserts. He immediately improved the performance of his windows.

“What attracted me to the Indow window insert product was that you don’t mess with your house at all. You just press the inserts into your window frames. There’s no mounting bracket. They’re fitted perfectly to each window so it’s just the pressure gasket that allows you to insert it into the window. They’re light and easy to install and remove again and again.”

For partners Greg and Eddie, using Standard Grade eliminated condensation in their mid-century modern Texas home. But Indow inserts are versatile. For a slightly higher price, our specialty grades offer an impressive array of solutions for the myriad challenges posed by windows whether it’s the need to block sunlight or UV rays or create privacy or quiet.

“I couldn’t be more pleased,” said Greg. “The Indow inserts have a very low profile.”
 

How Standard Grade Storm Window Inserts Perform:

  • Saves up to 20% on energy, whether winter heating bills or summer air conditioning.
  • 50 percent noise reduction (10-12 dBA) when placed over single-pane windows.*
  • Acoustic Grade is the best option for quieting outside noise and will achieve a 70 percent noise reduction (18.9 dBA) when placed over single-pane windows.
 
 

*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 inside storm windows 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.
