Frequently Asked Questions
Double glazed wooden window prices in the UK vary by timber type and style. Softwood double glazed windows range from £500 to £900 per window, hardwood options cost between £900 and £1,500 per window, and engineered timber versions range from £1,000 to £2,000 per window. Sash-style double glazed wooden windows are at the higher end of these ranges due to their more complex mechanism. Installation adds approximately £150 to £300 per window. Custom sizes, special glazing options, and premium finishes will increase the price. For a full house, expect to pay significantly more than equivalent uPVC installations.
Yes, double glazed wooden windows are among the most energy-efficient options available. Timber is a natural insulator with low thermal conductivity, and when combined with modern double glazing featuring argon gas filling and low-emissivity coatings, these windows achieve excellent U-values as low as 1.2 W/m2K. This comfortably meets and often exceeds UK Building Regulations requirements of 1.4 W/m2K. The combination of timber frames and double glazing significantly reduces heat loss, lowering heating bills and improving indoor comfort. Triple glazing can further enhance thermal performance for maximum energy savings.
Maintaining double glazed wooden windows involves regular care to protect the timber and keep the windows functioning well. Clean the frames and glass every few months with a mild detergent and soft cloth. Inspect frames annually for signs of rot, peeling paint, or cracks, and address any issues promptly. Repaint or re-stain the exterior every 3 to 5 years, or as recommended by the manufacturer. Lubricate hinges, locks, and sliding mechanisms annually. Check weatherstripping and seals to ensure they remain airtight. Modern factory-applied finishes and micro-porous paints have made maintenance easier than with older timber windows.
The best wood depends on your budget and requirements. Hardwoods such as oak, sapele, and meranti are the most durable, offering natural resistance to weathering and a rich, attractive grain. They are ideal for premium installations and heritage properties. Softwoods like Scandinavian redwood and pine are more affordable and work well when properly treated, though they require more frequent maintenance. Engineered timber, made from bonded layers of wood, provides excellent dimensional stability with minimal warping, making it ideal for larger windows. For UK conditions, sustainably sourced hardwood or engineered timber offers the best long-term performance.
Yes, double glazed wooden windows are often the preferred or required choice for listed buildings in the UK. Timber frames can be crafted to precisely replicate the original window profiles, mouldings, and proportions, preserving the building's historical character. Modern slim-profile double glazing units can be fitted within traditional-looking frames, providing the thermal and acoustic benefits of double glazing while maintaining an authentic appearance. Listed Building Consent is always required before replacing windows in a listed property, and the application should demonstrate that the new windows closely match the originals in design, materials, and finish.
Double glazed wooden windows can last 40 to 60 years or more with proper maintenance, depending on the timber type and quality of construction. Hardwood frames tend to outlast softwood, with some oak windows lasting over a century. The double glazing units themselves typically last 20 to 25 years before the seals may begin to fail and need replacing, but this is a straightforward repair that does not require replacing the timber frames. Regular maintenance including repainting, seal checks, and hardware lubrication is essential to achieving maximum lifespan. Well-maintained timber windows often outlast uPVC alternatives.
Double glazed wooden windows are available in a wide range of styles to suit any UK property. Casement windows are the most common, with side-hinged sashes that open outward. Sash windows feature two sliding panels and are the classic choice for Georgian, Victorian, and Edwardian homes. Bay and bow windows project outward to create extra space and light. Tilt and turn windows offer modern dual-function opening. French casement windows provide wide openings without a central mullion. Each style can be customised with Georgian bars, leaded glass, various moulding profiles, and a choice of stains or paint colours to match your property.
