The ADVANCE 70 French doors give you a wide, fully opening entrance that feels open and bright, while still being secure and energy efficient. They work well for connecting indoor and outdoor spaces, without losing heat or performance.

You can choose from chamfered or sculptured finishes, with options to open in or out. There are also full frame and Part M compliant low threshold options, making access easier where needed. With PAS 24 enhanced security, they offer a strong and dependable alternative to patio or bi-fold doors.

The ADVANCE 70 system is a complete 70mm window and door setup, so everything matches and works together. It’s available with double or triple glazing, and the 5-chamber design helps keep warmth in and energy bills down.

For strength, the system includes large reinforcement chambers. Steel sections can be added where extra rigidity is needed, or you can use RTR (Recycled Thermal Reinforcement) to improve thermal performance.

Security is built in as standard. When specified correctly, these French doors meet PAS 24 requirements and are Secured by Design approved, giving you added peace of mind.
