Bereco’s timber lipped casement windows—also known as “storm-proof”—are a classic British favourite, featuring a sash that overlaps the frame for a distinctive look. A decorative edge softens the sash design, and with a choice of pencil round or ovolo mouldings, these windows suit both traditional and modern properties. Crafted from sustainably sourced timber, they offer excellent energy efficiency, high security, and a wide range of customisation options across finishes, glazing, and ironmongery—delivering enduring style and performance.
