Premium Flush Sash Casement Windows
Elegant, Energy-Efficient, Timber-Look Windows
Our Premium Flush Sash Casement windows combine the timeless appeal of traditional timber joinery with the advanced benefits of modern uPVC technology. Designed to replicate pre-1932 heritage windows—with the sash sitting flush within the frame—they deliver refined aesthetics, exceptional performance, and effortless maintenance. Perfect for period properties, conservation areas, or homeowners seeking a sleek, contemporary finish.
Authentically Flush Frame Design
Inspired by classic timber windows, the sash sits seamlessly inside the outer frame, eliminating visible overlaps for a clean, elegant look. Unlike standard uPVC casements, Premium Flush Sash windows feature a double-rebated seal and patented hidden bubble gaskets—so there’s no shadow gap or unsightly brush pile. The result? Crisp, uninterrupted lines inside and out, creating a truly authentic timber-style appearance with all the advantages of modern engineering.
Exceptional Weather Resistance & Thermal Efficiency
Thanks to the innovative double-rebated system and bubble gasket technology, these windows provide outstanding weather protection and insulation. With U-values as low as 0.87 W/m²K, they exceed energy efficiency standards, helping to reduce heat loss and lower energy bills. Combined with advanced sealing, they keep draughts and moisture out, ensuring your home stays warm, comfortable, and quiet all year round.
Personalise your windows to suit your home’s character. Choose from an extensive range of colours, woodgrain finishes, and dual-colour combinations for a truly bespoke look. Whether you want a heritage-inspired tone or a bold contemporary shade, our Premium Flush Sash range offers endless possibilities. Matching frames, sashes, and accessories ensure a harmonious design that enhances your property’s kerb appeal.
Low Maintenance, Built to Last
- Forget sanding, staining, or painting. Premium Flush Sash casements are crafted from durable, rot-resistant uPVC that only needs a quick wipe to keep them looking pristine. Backed by comprehensive guarantees, these windows are designed for decades of reliable performance, giving you peace of mind and lasting beauty without the upkeep of traditional timber.
