Sliding Sash Window FAQs

It can be when it is sourced responsibly, and Hinson Custom Made says it works with timber suppliers accredited by FSC, PEFC and CPET. Timber is renewable, stores carbon as it grows and can offer a lower embodied footprint than some alternative frame materials, making it a strong option for homeowners who care about both appearance and environmental impact.

They often are, because timber sash windows are usually the closest visual match to original joinery and help preserve a building’s character. If your property has planning or conservation constraints, a bespoke design makes it easier to work towards the right proportions and detailing, although the exact requirements should always be checked for the individual property.

Yes. Hinson’s bespoke approach means you can choose f rom options such as clear, frosted, acoustic or slimline heritage glazing, along with paint or stain colours, ironmongery finishes and other design details. That flexibility helps you balance appearance, privacy, energy performance and period character.

Timber windows do need some upkeep, but modern finishes and good manufacturing standards make them much more manageable than many people expect. Regular cleaning and occasional repainting or re-staining every few years helps protect the timber, preserve the finish and keep the frames performing as they should.

With quality materials, proper finishing and routine care, timber sash windows can last for decades, with Hinson noting a lifespan of 60 years or more in many cases. Engineered timber and careful joinery also help reduce common issues such as warping, swelling and shrinkage.

Hinson Custom Made offers premium hardwood and softwood options including oak, ash and Accoya, depending on the look, performance and maintenance level you want. The best choice often depends on the style of the property, how exposed it is to the weather and the finish you want to live with long term.

Modern timber sash windows can be far more comfortable than ageing originals thanks to draught-proof seals and updated glazing options. Timber is a natural insulator too, so when the window is well made and fitted correctly it can help reduce heat loss, improve comfort and support better year-round performance.

Yes. Because each window is made to order, Hinson Custom Made can work around original proportions, glazing bars, sightlines and opening sizes so the new joinery feels right for the property. That is especially useful when you are replacing tired windows in homes with non-standard openings or original architectural details worth preserving.

No. They are a natural choice for period homes, but bespoke timber sash windows can also suit renovations, extensions and newer homes when you want a more character-led finish than a standard off-the-shelf window.

A sliding sash window is a traditional window style with one or two movable panels that slide vertically rather than opening outwards. Hinson Custom Made handcrafts bespoke timber sash windows that keep the classic Georgian, Victorian and Edwardian look while giving homeowners a made-to-measure fit.
