Made-to-Measure uPVC Casement Windows

Casement windows are one of the most versatile window styles available and can be configured with fixed panes and opening sashes in a wide variety of arrangements.

AWM Glass casement windows are made to the dimensions and options selected when ordering, allowing the finished frame to suit your individual opening rather than relying on a limited selection of standard sizes.

This makes them suitable for replacement windows, extensions, renovations and new-build projects where a particular width, height or configuration is required.

When ordering made-to-measure casement windows, consider:

  • The overall frame width and height
  • Which sections need to open
  • Top-hung or side-hung operation
  • Fixed glazed sections
  • Ventilation requirements
  • Frame colour and glazing
  • Cill and finishing options

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

Replacement uPVC Casement Windows

uPVC casement windows are a popular option for replacing existing windows because they can be configured around the dimensions and opening arrangement of the existing aperture.

Whether you are replacing a single window or ordering multiple windows for a larger renovation, the range allows you to select the layout and specification required for each opening.

Replacement casement windows can be suitable when:

  • Existing frames are damaged or deteriorating
  • You want to upgrade from older glazing
  • You need a different opening configuration
  • You are updating the appearance of the property
  • You require a made-to-measure replacement size

Always confirm your structural opening and required frame dimensions before ordering a replacement window.

Top-Hung, Side-Hung and Fixed Casement Windows

Top-Hung Casement Windows

Top-hung windows are hinged along the top edge and open outwards from the bottom. They are commonly used where ventilation is required without opening a full-height side-hung sash.

Side-Hung Casement Windows

Side-hung windows are hinged vertically and open outwards from the side. They can provide a larger opening and are available as part of many different casement window configurations.

Fixed Casement Sections

Fixed glazed sections do not open and can be combined with opening sashes to create larger window layouts while maximising natural light.

Double Glazed uPVC Casement Windows

All AWM Glass uPVC windows are supplied with double glazing as standard, fitted with Argon Filled, Low-E glass.

Low-E glass is designed to reduce heat transfer through the glazing, while Argon gas within the sealed unit provides additional insulation between the panes.

This specification is widely used across the window industry and provides a modern double-glazed solution for replacement, renovation and new-build projects.

Additional glazing options may also be available depending on the individual casement window selected.

Colours, Glazing and Casement Window Options

Your uPVC casement windows can be configured to suit both the appearance and practical requirements of your property.

The exact specification depends on the product selected, so use the individual configurator to confirm the available choices before placing your order.

Depending on the product, available options may include:

  • Made-to-measure width and height
  • External and internal frame colours
  • Top-hung, side-hung and fixed sections
  • Clear or obscure glazing
  • Toughened glass
  • Cill options
  • Handle colours
  • Trickle vents
  • Georgian bars
  • Square or diamond lead
  • Thermal performance options
  • Window fixing kits

Always use the individual product configurator to confirm the exact specification available for your chosen window.
