Among the vast array of window styles available today, flush timber casement windows stand out as one of the most adaptable and widely specified options for heritage properties.

Their timeless design and remarkable versatility have made them a cornerstone of British architecture for centuries. For property developers and architects working on period buildings, these windows offer an unmatched combination of traditional craftsmanship and contemporary efficiency, security and strength.

At Lomax + Wood, we have over 30 years of experience in crafting made-to-order flush timber casement windows that offer time-honoured style without compromising on functionality, making them particularly valuable in conservation areas and heritage homes where historical accuracy is essential.

The history of flush timber casement windows

Timber casement windows have been a fundamental feature of British architecture since the medieval period, though their design has evolved considerably over the centuries.

While early examples featured simple timber frames with small leaded glass panes, technological advancements in glass production during the 17th and 18th centuries enabled larger, clearer panes to be used.

Throughout their history, timber casements have demonstrated remarkable versatility, adapting to changing architectural fashions while maintaining their classic character. However, while brimming with charm, the flush timber casements of decades (and centuries) past didn’t offer the thermal efficiency and weatherproofing that modern properties require.

Combining style and efficiency in heritage windows

Fortunately, thanks to advancements in machinery and manufacturing technology, modern timber windows can be crafted to combine the very best of traditional design and modern performance.

At Lomax + Wood, our made-to-order timber casement windows are made with authenticity in mind, and play a vital role in maintaining architectural integrity within heritage homes.

Our flush timber casement windows represent the culmination of decades of industry expertise and technical innovation.

Each window frame is crafted from FSC® or PEFC Chain of Custody certified timber, with options including Engineered Redwood, Hardwood, Oak and Accoya, materials chosen for their strength and longevity.

Traditional features – including an elegant flush sash, slender glazing bars, and traditional butt hinges – all replicate original architectural details precisely, while PAS24 accreditation demonstrates the security of our windows.

Better still, with U-values as low as 1.0 and sound reduction capabilities up to 42dB, these windows deliver modern thermal and acoustic performance without compromising historical authenticity.

Our made-to-order windows are designed to keep interiors comfortable and protected against even the worst weather; our windows meet Class 9A certification for water permeability and Class CE2400 for wind resistance.

Customisation options: create the perfect timber casement windows for heritage homes

At Lomax + Wood, our timber windows are completely bespoke. Each window is made to order, allowing architects and developers to specify exact requirements for their heritage projects, from glazing patterns and finish options to opening configurations, ensuring a perfect match with the property’s historical character.

Our flush windows can be finished with beautiful natural stains or painted with any RAL colour, enabling exact matching with existing architectural features. Traditional ironmongery options such as ‘monkey tail’ handles ensure historical accuracy down to the smallest detail.

What are the key features to look for when selecting timber casement windows for period properties?

When selecting timber casement windows for heritage homes, look for authentic designs that match the property’s original windows, high-quality timber for durability, traditional hardware for an authentic look, and energy-efficient double glazing to improve insulation while preserving the heritage aesthetic.

Heritage windows in conservation areas

When working within conservation areas, window replacement must carefully balance preservation of character with building performance. Heritage flush casement windows routinely prove to be the most appropriate choice, offering authentic period details that satisfy planning requirements.

At Lomax + Wood, our extensive experience in manufacturing windows for conservation areas ensures that each installation maintains architectural integrity while providing modern standards of energy efficiency and security.

Projects such as this installation of timber casement windows for a property in the conservation area in Hampstead Garden Suburb showcase our dedication to honouring traditional style while ensuring exceptional performance. Within this project, every aspect of the original windows’ appearance was precisely measured and duplicated, from the distinctive sight lines to the period moulding details.
