Remembering Eddie Andelman

For many of us, Eddie Andelman was a familiar voice for decades. But beyond the microphone, he had a gift for bringing people together.

For many years, Eddie made Chelsea Days something special. At a time when the city needed it most, he created an event that brought excitement to Chelsea and gave local businesses, community organizations, and residents a chance to be part of something bigger.

His live broadcasts became a highlight of the celebration, and we were honored to be one of the stops along the way. Looking back at these photos brings back great memories—including the year Eddie officiated a wedding right here at JB Sash.

Thank you, Eddie, for everything you did for Chelsea & JB Sash and for the memories you helped create along the way.

Our condolences to the Andelman family, friends, and the many people whose lives you touched.

You are in our memories forever.

Some details are noticed the moment you walk into a room.

Others reveal themselves throughout the day—the way natural light fills the space, how the views become part of the design, and how every element works together.

Thoughtful homes are built one detail at a time.

INSTALL CLINIC — CAPE COD

A great install starts long before the unit goes into the opening.

Last week at Neptune Cape Cod, we brought builders, architects, installers, and project partners together for an evening focused on the details that matter most—installation strategy, building envelope integration, and the systems that help protect long-term performance.

From flashing and wall prep discussions to live demonstrations and field-driven questions, the goal is always the same:
bridge the gap between manufacturer best practices and what actually happens in the field.

Because getting installation right protects more than the window or door.
It protects the design intent, the envelope, the performance—and ultimately the client experience.

Thanks to everyone who joined us and helped make it a great night—and to our partners at Marvin, Benjamin Obdyke Inc. - Roof & Wall Products, Versatex Building Products and forest products for helping make these clinics what they are.

Missed this one?
We can bring the clinic to your jobsite.
