Historic Timber Casement Windows

Our historic timber casement windows have been developed to satisfy planning requirements for sympathetic replacement. For an exact match with the original we incorporate butt hinges and offer a selection of narrow, putty glazed sash profiles and layouts.

We offer the option of arched heads and internal arches to the sash, as well as circular designs. All of our historic timber casement windows can be arranged as square bay, angled bay and bow layouts. Whilst we offer a number of standard designs and layouts we can manufacture to bespoke needs.

Across our Historic Range we offer a selection of glazing options; including single and slim insulated glazing units (IGUs). Also commonly referred to as narrow cavity glazing, slim IGUs have helped in finding a balance between sympathetic restoration and achieving improved levels of performance. All glazing units can incorporate machine and hand drawn glass for an authentic reflection.

Machine drawn glass on slim IGUs makes it very hard to see that there is a second pane of glass at all. The inner pane would remain modern low E float glass but with a near perfect flatness the eye only picks up on the irregularity of the machine drawn pane.

Incorporating high performance features from the Traditional Range, our historic timber windows are available with discreetly positioned dual weather seal to help retain warmth and exclude noise and moisture. For high levels of security, a multi-point locking system is fitted.

We have ensured that performance of all of our timber windows and doors is enhanced through the production process. Our factory is humidity controlled and our advanced coating system provides maximum protection to the timber, while allowing it to breathe and let its natural beauty show through.

Original Glazing Methods

When the internally beaded glazing system is not an option, we have developed an external putty glazing system to exactly replicate the aesthetics of the original. Utilising modern materials to maximise performance, we are able to award a five year guarantee against glazing unit failure on all external putted installations.

Improved Energy Efficiency

To provide a compromise between energy efficiency and authenticity, we offer slim insulated glazing units, in addition to single glazing. All of our glazing units have been tested to industry standards and are supported by a Declaration of Performance.

High Security

A multi-point locking system provides locking points around the entirety of the frame. Additional security features, such as security laminated glass, can be incorporated but may be subject to planning consent in the replacement of the original casement window.
