Modern uPVC is a naturally poor conductor of heat, making it the ideal thermal barrier. Our frames feature a 5-chamber Aluplast internal profile and Argon gas-filled units to achieve industry-leading U-Values. This engineering stops heat loss by creating “dead air” pockets within the frame, ensuring your home maintains an A-Rated energy efficiency level and a lower carbon footprint year-round.
Castle Windows complies with all CE Marking requirements. All external windows exceed these standards, with full compliance handled by our expert installation team.
A world of choice for Casement, Bay, or Bow configurations.
High-spec 70mm profiles for maximum thermal retention.
Cutting-edge technology for long-term performance.
Made-to-measure units engineered to your exact specifications.
We recognise that your windows do more than fill an opening; they provide the primary barrier for thermal efficiency and home security.
Built for structural rigidity, our 70mm profiles are impact-resistant and immune to warping or rotting. The high-grade materials ensure frames remain weather-tight for decades, maintaining peak performance regardless of the season.
Security is integrated into every frame. Each window features multi-point locking systems (including Yale hardware). A critical feature is our Internal Beading; because the glass is secured from the inside, the units cannot be removed from the exterior, providing 24-hour protection.
Our windows act as a high-performance thermal shield. The multi-chambered design prevents thermal transfer and eliminates draughts, ensuring your home remains energy-efficient and comfortable even in the harshest winter conditions.
Forget the upkeep of painting traditional timber. Our uPVC units require nothing more than a simple wipe-clean with soapy water and an occasional drop of oil on the friction stays. These UV-stabilised, no-painting-required frames never fade or discolour.
