Improve thermal efficiency of your sash window

Home / Sash window double glazing / Improve thermal efficiency of your sash window

The application of contemporary methods to the challenges associated with owning timber-framed windows creates renovation solutions perfectly aligned with modern living.

The skilful integration of premium, modern details, without compromising authenticity, is the pursuit of the experienced restorer. Employing advanced materials and techniques – unavailable to the craftsmen of the past – provides invaluable benefits, such as enhanced living conditions, pristine aesthetics, exceptional durability and security, and advanced resistance against the elements.

Heritage Restorations extend the beauty within original characteristics and heighten the standards of comfort. An example is today’s advances in glazing technology: replacing single glazing with premium, vacuum-sealed double-glazed units incorporates superior thermal efficiency into original window frames.

________

Substituting thermally inefficient single glazing for modern, high specification glazing units provides many historic properties with dramatic transformations.

Originally, windows were designed to accommodate the profile of a single glass pane, without envisaging the possibility of sash window double glazing. Vacuum-sealed and with an ultra-slim profile, the double-glazing units available to the modern restorer can be professionally instated into the narrow rebates of heritage windows.

We partner with premium glaziers to provide property upgrades of unprecedented quality. As aesthetics and authentic design details are carefully preserved, we can upgrade glazing to most listed heritage properties.

________

With a glazing upgrade, a restoration project far exceeds the primary benefits of structural, functional and aesthetic rejuvenation. The positive impacts include:

Benefits of high efficient double glazing

Exceptional improvements to thermal and acoustic conditions

Our glazing is vacuum-sealed and 8x more efficient than single glazing, providing properties comparable to standard triple-glazing. External noise is greatly reduced.

Increased security

Laminated panes provide toughened units, without impacting on comfort.

Long-life

Greater durability and long-lasting vacuum seals deliver decades of fantastic service.

Fantastic transmission of natural light

Pristine clarity maximises solar gains and visibility.

Low impact

Our double-glazing units are 50% lighter than triple glazing which reduces the structural impacts and corrections needed to accommodate the additional weight.
