Flush Sash Windows for Contemporary and Traditional Trade Installations

Both PVCu and aluminium flush sash windows are a popular choice for a wide range of installation projects. They tastefully complement the sleek visual appearance of modern architecture and are often used in contemporary new-build projects. Their flush appearance is equally suited to more traditional properties making them the perfect choice for installations in country cottages and period homes.

PVCu trade sash windows are high quality and come in a massive range of colour options and traditional timber effect for people who want a timber window look.

Our trade sash windows in Poole, Devon and Wiltshire are designed to sit flush with the exterior wall of a property. This creates a sleek uniform aesthetic, unlike other window styles which sit proud of the exterior wall. Flush sash windows are an increasingly popular choice with homeowners wanting to create a unique appearance to their property exterior. They are a great addition to any installer’s product portfolio, both in PVCu and aluminium.
