CASEMENT WINDOWS – VERSATILE AND PRACTICAL
Casement windows remain a popular choice for their easy operation and excellent ventilation. Hinged at the side or top, they open outward, offering unobstructed views and enhanced airflow. Designed with high-security locking mechanisms and weatherproof seals, our casement windows provide lasting performance in all conditions. Available in uPVC, aluminium, and timber-effect finishes, they can be customised to complement traditional and contemporary homes.
FLUSH WINDOWS – SLEEK AND CONTEMPORARY
Flush windows sit level with the frame for a seamless, modern appearance, creating a clean, refined look. They combine timeless elegance with modern technology, which is ideal for heritage properties and new builds; we offer a range of energy-efficient flush windows designed to improve insulation while maintaining authentic period aesthetics. Choose from various frame colours, finishes, and glazing options to enhance your home's kerb appeal.
ALUMINIUM AND SLIDING SASH WINDOWS
Our aluminium windows provide a sleek, durable, and low-maintenance solution for modern homes, featuring slim frames and high thermal efficiency. For period properties, our sliding sash windows replicate classic charm while incorporating advanced materials for improved insulation and smooth operation. Whether you prefer sash windows' traditional elegance or aluminium's contemporary appeal, we offer customisable solutions to suit your style. Looking for new doors too?
We have just had windows fitted and I would highly recommend Christal Windows. Fantastic job from start to finish. Really pleased with the difference it's made to our house. Lovely lads: great job, great price.
