The way window U values are calculated has become more rigorous – but rest assured that all our window and door systems meet or exceed responsibilities under the new Part L regulations.

This requires buildings to be future-proofed with low carbon heating and world-leading levels of energy efficiency by 2025, with stringent U values for windows and doors.

Luckily, energy efficiency is always part of our design. We’ve been leading the way for nearly 50 years. It’s why our products are ready for the introduction of the new Part L. It’s also why they will be ready for any future regulations too.
