Replacement double glazed box sash windows in Georgian farmhouse with later additional Victorian stone bays
Grade II Listed Buildings
Increasing energy costs and climate change have highlighted the need for planning authorities to review historical approaches regarding thermal upgrades to grade II listed buildings. Our product delivers a building regulation compliant level of thermal efficiency whilst retaining the visual integrity of the historic building. The design has attracted a great deal of attention from conservation architects and planners alike. Most notably as the recipient of a heritage award for our work designing and manufacturing double glazed sash windows for a grade II listed Georgian town house in central Ludlow, with the full consent and approval of the local planning authority and conservation officer. Our windows have previously been approved in grade II listed projects by multiple local planning authorities across the UK, including Westminster, South Shropshire and Herefordshire. Read More
New Build Projects
Where customers are looking to recreate the Victorian or Georgian style in a modern building – for which the key element is timber box sash windows – we offer building regulation compliant sash windows correct to the traditional design.
Period House Projects
Buildings constructed during the Victorian and Edwardian periods (1837 – 1910) are generally not listed and in most cases still have the original box sash windows in place. Windows in such properties have very poor thermal and acoustic performance. Whilst we are happy to quote for major restoration and repair in unlisted properties, including the introduction of draught seals, we advise against it. Major overhauls are not cost effective and fail to adequately address thermal loss, acoustic issues (traffic noise etc.) and internal condensation. Replacement copies true to the original detailing will give significant thermal and acoustic upgrades, yet retain the building’s refined sight lines and intended design features.
Although replacement windows may be more expensive initially – compared to a major overhaul – the reduced heating costs and the durability of the windows compensate for this adequately over time. Introducing building regulation compliant box sash windows is an investment that increases value and will be recovered in the selling price of the property, unlike uPVC windows, which devalue period buildings.
For period buildings in which plastic or aluminium windows have been installed, we can reintroduce high-spec timber box sash windows appropriate to the age of the building, thereby restoring the original period façade.
