Why Flush Sash Windows Are the Perfect Blend of Tradition and Innovation
One of the major trends in the glazing industry over the past 10 years has been the rapid rise in popularity of flush sash windows. These windows replicate the classic look of timber, with the sash sitting completely level with the frame. Inspired by traditional timber joinery, these windows replicate the classic look while offering modern-day durability, energy efficiency, and security. Whether you’re updating a period property or adding character to a modern home, flush sash windows are a perfect choice.
Flush sash windows are known for their level appearance.
What is a Flush Sash Window?
As aforementioned, a flush sash window is designed so that the sashes (the parts of the window that open) sit level with the outer frame when closed. This creates a notably smooth finish that fits perfectly with both traditional and modern homes. Originally made from timber, today’s flush sash windows (sometimes referred to as flush casement windows) are available in advanced materials like uPVC and aluminium, offering a stylish, low-maintenance alternative.
The Benefits of Flush Sash Windows
Elegant and Versatile Design
The flush design creates a clean, refined look that works beautifully in both heritage and contemporary homes. With slim sightlines, these windows let in plenty of natural light, improving both the internal and external kerb appeal of your property.
Exceptional Energy Efficiency
Thanks to high-performance double glazing, flush sash windows from Crown provide excellent thermal insulation. This helps keep your home warm in winter and cool in summer, cutting down on energy bills in the process.
Low Maintenance, Long-Lasting
Unlike traditional timber windows, our uPVC and aluminium flush casement windows won’t rot or need regular repainting. They’re designed to look great for years with minimal upkeep.
Security You Can Rely On
Our flush sash windows are built with high-quality locking mechanisms, ensuring your home stays secure. Plus, all installations come with a 10-year warranty and an insurance-backed guarantee for extra peace of mind.
Perfect for Conservation Areas
If you live in a conservation area, you need windows that meet strict requirements while maintaining the historic charm of your property. Our flush sash windows are designed to satisfy most conservation area officers, offering a traditional look with all the benefits of modern glazing. If you choose one of our beautiful woodgrain finishes, you’re promised a window that will look at home in even the most rural of surroundings.
The heritage look that flush sash windows possess makes them perfect for traditional homes.
