Heritage Windows
Gowercroft heritage flush casement windows feature traditional design elements combined with modern materials and technology. With high-performance characteristics, these windows come with a comprehensive 10-year guarantee and provide excellent energy efficiency comparable to modern double-glazed products.
Crafted from Accoya® timber, known for its durability and energy efficiency, Gowercroft heritage flush casement windows seamlessly blend classic aesthetics with contemporary advancements.
The vacuum cavity glazing ensures U-values comparable to modern double glazing while maintaining a slim profile of only 8.3 mm.
The glazing is toughened for enhanced safety and security, providing optimal clarity without double reflection, making it suitable for conservation areas.
The frame design includes discreetly concealed gaskets, offering a clean and authentic appearance.
The heritage windows feature traditional butt hinges, concealed espagnolette locking, and a wide selection of handle styles and finishes to accommodate various design preferences. The slender 22 mm glazing bars and slim window profile create an elegant look that visually narrows the sections. The external bar design faithfully replicates the traditional putty pointing appearance.
Supplied with a comprehensive 10-year guarantee and are eligible for TimbaCare.
