01 Overview
One window, many possibilities
Proportioned for the property.
Configured for the room.
Casement windows can be side hung, top hung or combined with fixed panes to suit almost every style of home.
We’ll consider external appearance, ventilation, escape requirements, cleaning access and the way each room is used. The fully sculptured PVCu profile offers a softer, timber-inspired appearance while modern construction provides the performance expected from a new window.
Benefits
Everyday windows, carefully considered.
The right casement arrangement balances appearance, fresh air, security, warmth and practical access.
Flexible ventilation
Top- and side-hung openings can be combined with a secure night-vent position.
Layered security
Internal glazing and shootbolt and hingebolt locking help protect every opening sash.
Low-maintenance PVCu
Fully welded PVCu frames are straightforward to care for and made for everyday use.

Casement window collection
Opening styles & configurations
Explore single, paired and multi-pane layouts, including top-opening lights and bay-window arrangements. We will help select a practical configuration for ventilation, safety, access and appearance.
These images provide a visual guide. Opening sizes, hinge types and the final layout are selected around safety, ventilation, cleaning and building-regulation requirements, then confirmed after survey.
03 Colours
Make it yours
A finish for
every elevation.
Choose from crisp whites, subtle traditional tones, realistic woodgrain finishes and contemporary greys and blacks.
Several finishes can be paired with flat white internally, while bespoke flat colours offer further scope when the property calls for something more individual.
Screen colours are indicative. Bespoke colours may require additional lead time, and all finishes and current availability will be confirmed using the appropriate samples before ordering.
05 Hardware
Hardware and accessories
Practical details, room by room.
Hinges, ventilation and safety accessories should reflect where each window is installed.
- Child restrictors where appropriate
- Trickle ventilator options
- Easy-clean and fire-escape hinges
- Sash horns for additional character
Accessory suitability depends on window dimensions, location and regulatory requirements. We’ll confirm the appropriate hardware in your final schedule.
Security
Multiple layers, properly aligned.
Shootbolts and hingebolts secure opening sashes, while internal glazing prevents the glass from being removed externally. The night-vent position continues to use the locking points.
- Shootbolt and hingebolt locking
- Internally retained glazing
- Secure night ventilation position
Energy efficiency
A+ as standard. A++ available.
A strong five-chambered profile, welded joints, tight weather seals and energy-efficient glass combine in the complete window.
Ratings apply to the specified supplier window systems. The exact energy label and glass construction will be confirmed with your quotation.

10 Case study
Brigstock window transformation
A brighter, more contemporary frontage.
Our client wanted to replace the ageing windows and give her Brigstock home a cleaner, fresher appearance. We worked closely with her to explore suitable designs and colour combinations before agreeing a crisp white casement style that complements the existing brickwork.
The completed installation has transformed the frontage, creating a brighter and more modern finish while remaining sympathetic to the character of the property.

Choosing casement windows.
What is the difference between double and triple glazing?
The triple-glazed option adds an additional energy-efficient pane and can increase the complete window rating from A+ to A++. We’ll explain the practical difference for your home and budget.

Yes. Casement windows are highly configurable, so opening types and fixed panes can be combined to suit the appearance and needs of each room.
