If you are looking for the quintessential British window layout, the Style 9 is absolutely spot on. It combines the everyday practicality of a side-opening sash with the brilliant light-gathering properties of a fixed upper pane.

Let’s break down exactly how this beautifully engineered upvc flush casement is put together:

1. The Fixed Toplight (Upper Section) The top portion of the window is a completely fixed pane. By removing any opening mechanisms or bulky frames from this section, it acts as a dedicated light-well, pulling maximum natural daylight into your room regardless of whether the window below is open or closed.

2. The Right-Hinged Casement (Lower Section) Sitting seamlessly beneath the toplight is the primary opening sash. Hinged securely on the right-hand side, the left edge swings smoothly outwards. This side-hung mechanism is a timeless choice for upvc windows, allowing you to catch passing breezes and funnel massive amounts of fresh air directly into your living space on a warm summer’s day.

Why choose a fixed, side-hung, flush casement window?

• Maximum Ventilation: Unlike tilt-in styles, a side-hung lower sash can be pushed wide open, making it incredibly effective for rapidly cooling down a hot kitchen or living room.

• Fire Safety & Egress: Depending on the overall size of the aperture, side-hung lower sashes are often used to meet building regulations for fire escape routes on upper floors.

• The Flush Aesthetic: Even with this traditional split-pane setup, the magic of the flush design means both the fixed top and the side-hung bottom sit perfectly flush with the exterior frame when shut. It delivers the sharp, premium look of 19th-century timber craftsmanship without any of the modern-day maintenance headaches.

Ideal Placement: This layout is the ultimate all-rounder. It looks just as elegant on the front elevation of a period cottage as it does framing the view in a newly built extension.
