Vertical Sliding Sash Windows

Conservation Approved Sash Window Specialists in Hampshire, Berkshire, Surrey, Dorset & West Sussex

Quality Sash Windows experts in Hampshire, Berkshire, Surrey, Dorset & West Sussex

Sash windows are a classic, timeless design that is often found in Georgian or Victorian style houses. Sash windows are divided into two panes - a fixed outer pane at the top and a lower inner pane that slides open vertically. These offer a great level of adjustment to the ventilation in a property, whilst remaining flush to the walls in any position.

Sash Windows - Authentic appearance, modern materials

Choosing new sash windows used to mean expensive, high-maintenance timber windows that required frequent painting. Fortunately, that compromise is now a thing of the past. With Brackenwood's sliding sash collection, you can enjoy expertly crafted sash windows that are impeccably finished and virtually indistinguishable from genuine wooden windows.

Materials Available for Sash Windows

Choose the right window frame material


For most homeowners, uPVC keeps costs low while performing reliably year after year. The weather-resistant plastic requires little maintenance - just an occasional clean with soap and water keeps uPVC looking fresh.

Versatile uPVC suits traditional or contemporary homes. Though slightly less durable than aluminium over decades, uPVC delivers hassle-free, cost-effective protection.

With the highest sustainability, security, style, and viewing potential, aluminium window frames bring unique advantages. The durable, low-maintenance nature provides long-lasting, hassle-free performance.

For a more sustainable, ethical window with several custom styling possibilities, superior views, and military-level robustness, aluminium frames are the superior choice.

Hampshire, Berkshire, Surrey, Dorset & West Sussex Wooden Window Company


Wooden window frames were the most common choice before the introduction of low-cost uPVC. Wood has the lowest heat conductivity of the common frame materials, whilst also being environmentally friendly.

Listed buildings often require a timber-look window installation, however modern aluminium and uPVC can perfectly mimic the appearance and options of wooden windows.
