Commercial Insulation Solutions

Noise and drafts cost you money. Not only do drafty windows lead to high energy bills, they make employees, customers, and tenants uncomfortable and dissatisfied. If you’ve looked into replacing windows in a commercial building, you know how expensive and disruptive it is. With commercial storm windows, you can reduce hotel noise or help with soundproofing windows for office spaces with no construction.

Historic Building Renovations

Clients applying for a Historic Tax Credit or those in historic districts want a solution that preserves original windows. The inserts blend into the interior frame and are invisible from the exterior.


How It Works

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.

Unique Grade Types for Unique Commercial Needs

Your project type is commercial, but is Commercial Grade the most appropriate for your needs? 

Both commercial grade types come with an abrasion-resistant film, which is necessary for office spaces that are cleaned routinely or have multiple people handling the inserts regularly. 

Each grade blocks drafts. Our premium grades have special features to make your existing windows work the way they’re designed to. To determine the best grade type, consider your primary needs and then consider how trafficked your office space is.

Commercial Project Testimonials


Pilot Program

An order of Indow window inserts to address your office window needs will come at a fraction of the cost of a commercial window replacement project, but we understand any project you pursue will affect your company’s budget. That’s why we recommend a pilot project to start off any large commercial project. 

Starting a pilot project with Indow does not commit you to any future order. If you like the results, we will be happy to work with you on a follow-on order. If you decide on another solution after completing your pilot with us, we thank you for considering Indow.
