01 Overview
Something old, something new
Understated outside.
Modern underneath.
A flush casement is defined by the opening sash sitting level with the outer frame instead of projecting beyond it.
That simple change creates a calmer, timber-inspired exterior that works naturally on traditional properties and equally well on contemporary homes with minimalist detailing. Behind the clean line is a modern PVCu window designed for security, weather resistance and easy maintenance.
Benefits
Character without the compromise.
The flush profile brings traditional visual restraint together with the practical qualities expected from a modern replacement window.
Timber-inspired character
Understated proportions suit cottages, period homes and heritage-influenced projects.
Modern protection
Shootbolt locking and internal glazing add contemporary security beneath the traditional look.
Low-maintenance PVCu
Fully welded PVCu frames offer the appearance without the regular treatment required by timber.
02 Styles
A versatile design language
Traditional character,
configured for your home.
Flush casement windows can combine side-hung, top-hung and fixed panes while keeping the opening sash level with the outer frame for a cleaner elevation.
Flush casement collection
Opening styles & configurations
Use these arrangements as a visual guide for single, paired and multi-pane windows, including top-opening lights and bay configurations. We will help shape the final layout around the property and each room.
These images provide a visual reference. Opening sizes, hinge types and the final layout are selected around ventilation, cleaning, safety and escape requirements, then confirmed after survey.
03 Colours
Make it yours
A finish that respects
the architecture.
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 provide additional flexibility for individual projects.
This collection is a visual reference and screen colours are indicative. Bespoke colours may require additional lead time; finishes and current availability will be confirmed using the appropriate samples before ordering.

10 Case study
Corby home refurbishment
A coordinated update from windows to entrance.
Brooke Construction Services is supporting the wider refurbishment of this Corby property, helping the client modernise the home while creating a finish that feels considered across the whole exterior.
As part of the work, we installed a complete set of flush casement windows with clean, balanced sightlines and modern energy performance. A green timber-core composite entrance door was fitted alongside them, adding character and giving the frontage a distinctive focal point. Together, the new windows and door provide a cohesive update with improved insulation, security and kerb appeal.

11 FAQs
Useful answers
Choosing flush casement windows.
What makes a casement window “flush”?
The opening sash sits level with the face of the outer frame rather than standing proud, creating a flatter and more understated external appearance.
Are flush windows only suitable for period homes?
No. Their timber-inspired lines work well on traditional properties, while the restrained geometry also suits contemporary and minimalist architecture.
How are the windows secured?
Opening sashes use shootbolt locking and the glass is retained internally so it cannot simply be removed from the outside.
Do the windows meet current building regulations?
The supplied windows are designed to meet or exceed current applicable requirements. The relevant safety, ventilation and escape details will be considered within the final schedule.
What does the 10-year guarantee cover?
The supplied flush casement windows carry a 10-year product guarantee. Applicable terms and exact coverage will be provided with your quotation.
