What Are
UPVC Flush Windows?

Flush casement windows are designed so the sash sits level within the outer frame — creating a smooth, flat appearance from the outside. This design mimics traditional timber windows found in period homes, but with all the benefits of modern UPVC. You get enhanced insulation, robust security features, and low-maintenance durability — all while maintaining a timeless aesthetic.

Energy Efficiency & Security

Energy Efficiency

Our UPVC Flush Casement Windows are engineered for outstanding thermal performance. With U-values as low as 1.0 W/m²K and Window Energy Ratings of up to A++, they help keep your home warm, comfortable, and cost-efficient all year round.

The multi-chambered frame design works together with high-performance glazing to reduce heat loss and limit cold spots. Whether you choose double or triple glazing, these windows provide excellent insulation and help lower energy bills over time.

By improving the energy efficiency of your home, our flush windows not only enhance comfort but also reduce your environmental footprint — all without compromising on style.

Security

Security is built into every aspect of our flush casement windows. Each unit is manufactured to meet PAS 24:2022 standards, ensuring it passes rigorous modern security testing for domestic use.

Advanced multi-point locking systems, robust hardware, and secure frame construction all contribute to high levels of protection. For added peace of mind, you can choose options that meet the police-approved Secured by Design specification.
