Flush Sash Windows
Traditional in appearance and modern in performance, Pearl Window Systems’ Flush Sash windows combine clean external lines with the thermal efficiency, security and low maintenance benefits of modern PVCu.
Looks Like Traditional Timber. Performs Like Modern PVCu.
Flush sash windows are designed to recreate the clean, traditional appearance of timber windows, with the opening sash sitting flush within the outer frame. This makes them particularly suited to properties where traditional styling is important, while still providing the benefits of modern PVCu construction.
Available as a standard 70mm system, with the option of our 80mm Resurgence system, Flush Sash provides the flexibility to achieve the right balance of appearance, performance and specification for each project.
Traditional Styling Without the Traditional Maintenance
The Flush Sash system combines a sculptured profile and flush external finish with modern glazing, thermal and security options. With a wide choice of colours, finishes, hardware and glazing configurations, the system can be specified to complement both traditional and contemporary properties.
