French Window

Order made-to-measure uPVC French windows online from AWM Glass, available in standard French window and toplight configurations for replacement, renovation and new-build projects.

French windows are similar to traditional casement windows but open without a fixed central mullion between the two opening sashes. When both sides are opened, this creates a wide, unobstructed opening that can provide increased ventilation, easier access and clearer views through the window.

All AWM Glass uPVC windows come with double glazing as standard, fitted with Argon Filled, Low-E glass. Depending on the product selected, you can also configure the required dimensions, frame colour, glazing, cill, handles, trickle vents and decorative options.

Our French windows are made to measure and use the Advance 70 uPVC window system, designed to provide strong thermal, weather and security performance for residential applications.

What Is a French Window?

A French window uses two opening sashes positioned side by side. Unlike many conventional casement arrangements, there is no permanently fixed central mullion separating the opening sections.

When both sashes are opened, the result is a broad clear opening without a central frame section obstructing the space between them.

This makes French windows particularly useful where you want increased ventilation, a wider opening or an uninterrupted view when the window is fully open.

French windows can be suitable for:

  • Replacement windows in existing properties
  • Bedrooms and upper-floor rooms
  • Renovation and refurbishment projects
  • New-build properties
  • Openings where a wider clear aperture is preferred
  • Rooms where increased ventilation is useful

Where a window is intended to provide an emergency escape opening, always ensure the finished size and installation meet the applicable Building Regulations.

French Window or French Window with Toplight?

French Window

The standard French window uses two opening sashes to provide a wide clear opening without a fixed central mullion. It is a practical choice where the available opening does not require additional glazing above the main window.

French Window with Toplight

A toplight configuration adds an additional glazed section above the main French window. This can suit taller structural openings while retaining the wide-opening French window arrangement below.

Made-to-Measure French Casement Windows

Each French window is configured around the dimensions and specification selected when ordering. This allows the finished frame to be matched more closely to your individual structural opening than relying on a limited selection of standard window sizes.

The made-to-measure approach is suitable for replacement windows, extensions, renovation work and new-build projects where the width, height or finish needs to suit a particular property.

Before ordering, consider:

  • The overall frame width and height
  • Whether a standard or toplight configuration is required
  • Required frame colours
  • Glazing and privacy requirements
  • Cill requirements
  • Ventilation options
  • Any decorative glazing features

Check all dimensions carefully before ordering because your windows will be manufactured using the measurements supplied.
