How Commercial Grade Inserts Work

Indow inserts press into the interior of a window frame and therefore don’t require any outside scaffolding to install. Our Commercial Grade inserts are custom made for each window with laser measurements so they have a precise, tight fit that makes a space immediately quieter, more comfortable and more energy efficient.

Each insert is edged in our patented silicone compression tubing. Our commercial interior storm window inserts press into existing window frames without damaging mounting brackets, perfect for historic buildings. Mullions can be used for especially large windows.

Our Commercial Grade inserts are durable. They’re made of tough, scratch-resistant acrylic glazing that provides reliable commercial window insulation. Commercial Grade inserts can withstand strong cleaning agents like Windex without clouding.
