Epwin Window Systems has launched the latest generation of its Flush Casement Window, now available across its Profile 22 and Spectus window and door system brands.
The enhanced design delivers improved thermal performance, expanded security compatibility and refined aesthetics, the company said.
Commercial director Ray McGrady said: “From improved thermal performance and enhanced PAS 24 compatibility to refined styling, it’s a window system that enables our customers to stay ahead of changing regulations and evolving project expectations.”
Designed with the Future Homes and Buildings Standards in mind, the new window offers expanded glazing options, including triple-glazed configurations, achieving U-values as low as 0.8W/m²K.
Security performance has also been enhanced. A strengthened sash design, greater hardware compatibility and PAS 24 approval across all glazing bead options mean the window achieves compliance across every glazing option and sash size as standard. The system is also suitable for Secured by Design applications.
Aesthetic improvements include a new flush internal appearance, delivering a premium, contemporary finish while maintaining ‘authentic heritage styling’.
The system also delivers improved weather performance, making it suitable for more exposed locations, while increased maximum sash sizes for both top-hung and side-hung windows allow fabricators and installers to meet growing demand for larger glazed areas.
