Double Glazing Sash Window


sash window double glazingDouble Glazing Timber Sash Windows

Thermal & acoustic insulation, as well as increased security, are some of the key benefits that double glazing offers. For period homeowners replacement uPVC or metal double glazed 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 our 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 Restoration 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.
