Authentic Heritage-Style Wooden Windows

Timber sash windows are and have always been one of the defining aspects of some of the most beautiful homes that have been built and reside in the UK. From stately Period homes to modern residential buildings, Lomax + Wood are specialists in supplying and installing timber double-glazed sash windows.

Our collection of sash windows conscientiously replicates those ageless window designs down to the finest detail and solutions required for listed buildings and conservation areas. These quality wooden sash windows are appropriate for Georgian, Victorian or other period properties within a conservation area. Our sash windows have been used in the construction of newly built properties, complete renovation projects, house extensions and commercial buildings such as hotels and period office buildings.

Double Glazed Sash Windows

Our Timber sash windows are made to our client’s specifications, from design requirements and the type of double glazing used, keeping the appearance of the sash windows in tune with the period properties that we supply our windows for. We have supplied and installed timber sash windows for Georgian and Victorian stately homes throughout the UK, ensuring that the conservation design of the sash windows has been preserved at all times.

Although timber sash windows are synonymous with Period properties, we also design and install wooden sash windows for newly built properties, complete renovation projects, house extensions, and stylish windows required for commercial buildings such as hotels and period office buildings in the UK.

Replacement Timber Sash Windows

Replacing your existing timber-framed wooden sash windows will vary from project to project. Still, in essence, we need to note the current dimensions and designs of the old timber sash windows and ensure that they conform to the specifications under the conservation act within your area. We will aim to make sure that when we replace your wooden sash windows, they will be identical to the existing design but with far greater insulation properties if it is permitted.

We find that conservation areas might dictate that single glazed sash windows need to be used to adhere to the surrounding properties again; this is part of our services to ensure that the sash windows we provide are not different to the local specifications.

Suppose there are no conservation rules dictating the type of sash windows that must be manufactured and installed on your house. In that case, we can provide double or triple glazed replacement timber sash windows, which will be far more insulating and energy-efficient when compared to the existing sash windows.

A good example of replacement sash windows for a period property would be Bolsover Street, Fitzrover, London.

New Timber Sash Windows

We work with several builders and architects who are in the process of designing or developing modern houses, whereby their underlying clients specify bespoke new timber sash windows, giving the appearance of a traditionally built Period property on a country estate, while the construction method is entirely modern.

If you’re curious to see how a modern Period property or new build would look like with new sash windows will look like we recommend that you look at the either of the below case studies:
