Thermal & acoustic insulation as well as increased security are some of the key benefits that double glazing offers. For many period home owners replacement windows are an unacceptable option as they detract from the authentic charm of the property. At Sash Window Specialist we understand the need to incorporate modern advances into period homes without significantly altering the appearance.

We supply & install authentic wooden replica sashes into existing timber frames, paint finished and double glazed with energy efficient (low E) glass.  In some cases it is even possible for us to convert existing single glazed sashes to accept double glazed units.  Double glazing combined with our recondition and draught seal procedure provides an obvious overall improvement to the comfort of your home. 

All of our work is designed to be as unobtrusive as possible, being machined into the timber components to become an "invisible" part of the window.  The appearance of the property is virtually unaltered, preserving the character and charm, yet offering you the increased comforts of modern alternatives.
