What Is a Flush Casement Window?
Flush casement windows are a stylish home improvement that are rising in popularity across Buckinghamshire, Hertfordshire, and Oxfordshire in particular.
If you’re wondering what makes the style stand out, in simple terms a flush casement window is a type of window where the sash (the part that opens) sits flat or “flush” within the frame. Unlike standard or lipped casement windows, which project slightly outward, flush casements offer a sleeker, more seamless look that works beautifully on both period properties and more modern homes.
Designed to replicate the appearance of traditional timber windows, flush casement windows combine heritage style with contemporary performance. Whether you live in a listed building, a conservation area, or simply want to upgrade the exterior of your home, flush sash windows are an excellent choice.
Flush casement windows are enjoying a rise in popularity across the country – and it’s not hard to see why!
Key Features of Flush Casement Windows
Aesthetic Appeal
The flush design creates a smooth, flat surface between the window sash and frame. This gives your home a refined, minimalist aesthetic that works especially well for period properties and modern extensions alike.
Energy Efficiency
Flush casement windows from Double Glazing Direct are made with multi-chambered uPVC or contemporary aluminium profiles and high-quality double or triple glazing. These features help to trap warm air inside and keep draughts out, which can reduce your energy bills and lower your carbon footprint.
Ventilation and Functionality
Just like regular casement windows, flush styles are hinged at the side and open outwards. This allows for excellent ventilation and ease of use while maintaining that beautiful flush appearance.
Peace of Mind Security
Security features are a top priority for homeowners, which is why all our flush windows come with secure locking mechanisms and the option to upgrade to PAS 24: 2016 Enhanced Security Performance status. You’ll have complete peace of mind knowing your windows are built to resist intruders.
Why Choose Flush Casement Windows?
Flush casement windows offer a number of practical and visual benefits, including:
- Suitability for conservation areas and historic buildings
- Ideal for replicating traditional timber windows
- Perfect for modern homes looking for a minimalist look
- Reduce energy bills thanks to excellent thermal performance
- Durable and low-maintenance compared to real timber windows
- Fully customisable in colour, hardware, and glazing
They’re one of the most popular window styles we install, and for good reason!
uPVC vs Aluminium Flush Sash – Which Is Best?
When it comes to choosing between uPVC and aluminium flush sash windows, there’s no wrong answer – it all depends on your priorities and style preferences.
uPVC Flush Casement Windows
uPVC is a durable, cost-effective material that offers excellent energy efficiency. Our uPVC flush casement windows are available in a range of finishes, including realistic woodgrain effects, making them perfect for traditional and contemporary properties alike. They’re also easy to clean and maintain.
Aluminium Flush Casement Windows
Aluminium, on the other hand, is all about sleek aesthetics and incredible strength. It allows for ultra-slim window frames, which means more natural light in your home and fantastic views. Aluminium windows are also extremely durable and resistant to warping, making them ideal for long-term performance with minimal upkeep.
Both materials comply with UK building regulations and offer fantastic performance – it just depends on your personal preference!
