If you wander down the Georgian high street in the historic market town of Ludlow, you’d be forgiven for thinking each house had kept its original sash windows. Even at number 44 Mill Street, which recently scooped the prestigious Ludlow Heritage Award for its replacement double glazed, hand blown glass windows made by Sash Restoration Co (Hereford) Ltd using Edgetech’s warm edge spacer system.

When the owner of the grade II listed house decided to change the tired windows and improve acoustic and energy performance, the Ludlow Conservation Area Advisory Committee’s high standards of conservation demanded that replacement windows be in keeping with the other period properties in the area. The homeowner went straight to sash window specialists, Sash Restoration Company for advice.

Using traditional hand blown glass, 20mm solid through glazing bars and Duralite® warm edge spacer bar from Edgetech UK, a Quanex company, Sash Restoration Co created individual double glazed units in the finest timber box sash frames that are Document L compliant and achieve conservation requirements. The committee was so impressed it gave the project the Ludlow Heritage Award.

Ronnie Salisbury, Managing Director at Sash Restoration explains: “The committee and Ludlow residents are extremely protective of their history, so to have our product accepted for the project was a huge achievement, and to win an award for it is great for us.

“We’ve been using Duralite in our windows for 12 years and Edgetech has always been very supportive. They even got their hands dirty making the units and testing them.

“Edgetech’s single seal warm edge spacer provides a unique approach to solving the challenge of double glazing in conservation areas. It’s a heat processed, flexible product with low sightlines, so it follows the variable surface of the traditional hand blown glass we use perfectly. It creates a finish that is softer on the eye and makes it almost impossible to tell that it’s a double glazed unit.”
