Windows are always a significant investment, whether you’re opting for uPVC, aluminium, or timber; there’s no way around it. But pound for pound, timber Windows give you the best value.
Because timber is a natural material, you’re guaranteed a longer lifespan than other popular alternatives. On average, uPVC windows provide 16–18 years of use, whereas timber Windows often last several decades. Why? Simply put, timber is easier to maintain and repair long after installation, while synthetic materials tend to degrade or become brittle over time.
Sustainability
Unlike uPVC, which is made entirely from artificial materials and petroleum-based products, timber is a renewable, biodegradable, and sustainable material.
Although timber involves felling trees, this can be done responsibly. At Mumford & Wood, all our timber is sourced from managed forests, where felled trees are replaced to promote continuous replanting. The result? A carbon-negative material that absorbs more CO₂ during the regrowth cycle than is emitted during processing.
Moreover, sustainable forestry enables forest floors and ecosystems to thrive. Tree canopies block sunlight from reaching plants and wildlife beneath, so selective and thoughtful harvesting encourages biodiversity and natural regeneration.
All timber used by Mumford & Wood is FSC® Certified (FSC-C124392) — giving you complete confidence in the sustainability and traceability of our Windows and Doors.
Insulation
Timber doesn’t just look good, it performs brilliantly too. Thanks to its natural density, timber is one of the best insulators available. It retains heat during winter and reduces energy waste, making your home more comfortable and cost-effective.
Compared to uPVC or aluminium, timber Windows consistently offer superior energy performance. This translates to better results on your EPC rating, which can even increase your property value by up to 14%.
Aesthetics
There’s nothing quite like the elegance of timber. Whether you live in a period property, a home in a conservation area, or just love a refined aesthetic, timber Windows offer timeless charm.
With beautifully crafted frames and a wide variety of styles, finishes and colours, timber windows blend seamlessly into both traditional and contemporary homes.
