The UK's most popular window style, blending slim sightlines with a high-performance double-action bubble gasket to keep draughts out and can achieve a WER A+ rating (up to A++ with triple glazing).
Inspired by traditional timber joinery, each sash sits flush within a 70mm deep frame with bevelled edges — a striking, heritage-friendly look that can achieve Passivhaus-level performance.
Tilt inward for safe, secure ventilation, or turn fully open for easy cleaning from inside. Built on the Optima 22 profile with multi-point locking for extra peace of mind.
All the timeless character of traditional timber sash windows — pole eyes, tilt knobs and sash lifts included — with the low maintenance and efficiency of modern uPVC.
Ultra-slim sightlines from as little as 65mm, with polyamide thermal breaks for excellent insulation and over 150 RAL colours to choose from — including dual-colour finishes.
A third pane and gas-filled cavity for a U-value as low as 0.7 W/m²K — keeping your home warmer, quieter and more secure, on any of our window styles.

Cost depends on material, size, style and how many windows you need. Use the quote form above for a free, tailored price — there's no obligation to book.
Standard casement windows have sashes that sit slightly proud of the frame, while flush casement sashes sit flush with the outer frame for a sleeker, more traditional look often suited to period properties and conservation areas.
It depends on your property and priorities. Casement and flush casement suit most homes and budgets, sliding sash adds period character, tilt & turn makes upstairs windows easy to clean, and aluminium gives the slimmest, most contemporary sightlines.
Our uPVC windows use multi-chambered frames that can achieve a WER rating of A+ with double glazing, or up to A++ with triple glazing — helping reduce heat loss and lower your energy bills.
Most window installations are completed within one to two days, depending on the size and number of windows. We'll always agree a clear timeframe with you beforehand.
