Showroom

Our Boston design center and Marvin showroom brings new meaning to the term “window shopping.”

It All Starts Here

Start your residential or commercial project in the JB Sash Window and Door Design Center & Marvin Showroom. Explore hundreds of products with the guidance of our window and door experts. 

What's on Display

Our design center and showroom spans two floors. It features a vast selection of Marvin products, including the Signature, Elevate and Essential window and door collections.

Visitors to our Boston showroom can see, feel, and compare innovative products. Experience top-of-the-line items such as Marvin’s breakthrough Skycove, a projected glass window that can add up to 20 square feet of space to your home, and the Awaken smart skylight. 

Let us help you decide among wood, aluminum-clad, fiberglass, and vinyl window and doors. We’ll discuss their differences and advantages, and determine the best fit for your needs.

In addition to window and doors, our JB Sash showroom features premiere brands of skylights, hardware, and millwork.
