Authentic and Stylish
Reminiscent of early 19th-century timber windows, our Flush windows are ideal for heritage homes and properties in conservation areas. Unlike chamfered and sculptured styles, this window sits flush in its frame, adding traditional, understated elegance to your property while also offering optimal thermal and acoustic insulation.
Insulated Windows
With a range of double-glazed and triple-glazed windows to choose from, our products will keep your property weatherproof and draughtproof. The five-chamber uPVC frames of the Flush act as an outstanding thermal barrier against driving winds and rain, even in the most exposed locations.
Colours and Finishes
All Flush windows are available with your choice of 18 foiled colour finishes, ranging from a smooth white uPVC finish to a traditional stained or painted woodgrain. Our manufacturing process also allows you to choose different colours for the interior and exterior if you wish – for example, you might want a warm timber effect, such as Irish Oak, for the exterior, and a clean, bright white for the inside.

Security Design

What’s more, our prestige windows are manufactured with a high level of security, including:
  • A Shoot Bolt with Multi-Mushroom Cams
  • Hinge Protection with Security Claws as Standard
  • A Range of Lockable Handles
