Modern innovation with traditional values

Blending timeless elegance with contemporary innovation, Patchett Joinery’s Timber Spiral Balance Sash Windows are a perfect marriage of traditional aesthetics and cutting-edge performance. Expertly crafted to replicate the iconic charm of historical sash windows while delivering unparalleled energy efficiency and functionality.

With meticulous attention to detail, our skilled joiners recreate the intricate detailing and proportions of classic sash windows, ensuring an authentic look that harmonises with the architectural character of your home.

Incorporating advanced spiral balance technology, these sash windows glide effortlessly, ensuring smooth operation and easy maintenance. The spring mechanism offers significant advantages over traditional systems, eliminating issues associated with fraying cords or fallen weights. The concealed balance system not only enhances the aesthetic appeal but also eliminates the need for cumbersome weights and pulleys, making these windows a practical choice for both new builds and renovations.

What are Spiral Sash Balances?

Spiral sash balances are an innovative mechanism designed to provide smooth and effortless operation for modern sash windows. These balances consist of a spiral spring housed within a balance tube, working together to counterbalance the weight of the sash. This ingenious system allows the sash to glide up and down with ease, eliminating the need for traditional sash cords and pulleys. The result is a durable and low-maintenance solution that enhances the functionality of your windows. Spiral sash balances are particularly popular in modern sash windows due to their reliability and ease of use, making them an excellent choice for homeowners seeking a blend of classic style and contemporary convenience.

Using only a water-based painting system which allows timber to “breathe” and adapt to climatic changes, our finishes provide maximum protection against weathering, fungal attack and UV degradation. The water-based application significantly reduces harmful emissions and disposal issues associated with solvent based systems.

Working with our paint partner, Sikkens, we can finish in any RAL colour, stain, or match against all well known paint ranges and brands. With the ability to have different internal and external finishes, your windows and doors can be finished just as you require.

Our factory is audited quarterly to ensure that the finished product has the highest quality paint finish and performance you would expect.
