Flexible Design Options

This smooth and easy to operate bi fold door with robust roller and panel guides can be tailored to your specific requirements.

Use flexible opening options and multiple transom configurations to create your authentic time-honored design.

To complement our Heritage bi fold door we have commissioned authentic hardware in various styles and finishes and if required these can be powder coated to match the frame work.

Peace of mind premium security

A tough multi-point locking mechanism protected with the Avocet ABS euro cylinder further enhances the appeal of this elegant bi fold door manufactured to our usual industry leading high standards.

The clever locking system of the Avocet ABS® diamond grade cylinder knows when it has been snap attacked and fires into action to create a robust barrier to entry. The patented Active Cam TechnologyTM is hidden deep within a solid Molybdenum cam which is 20% stronger than steel, and delivers ultimate resistance against a lock snapping attack and snap/twist manipulation. All of the snap technology is focused on the outside part of the lock only. This makes sure that maximum strength is given to the inner part of the lock - the part that has the job of securing your door.

The guys did an excellent job today removing my old doors and then installing my new bi-folds... old doors and frame out cleanly and then installed the new doors very neatly. All in all an excellent job well done. The new bi-fold doors look really good!

I ordered three sets of doors to self-install: the team at Marlin were really helpful with all my technical queries, which helped make sure my orders were mm perfect and the doors all went in smoothly with the glazing bars all lining up precisely. They look great - will do it all again in our next house!

 

Rated 5.0 out of 5 Dom B

From our initial contact with Marlin Windows we have been very impressed. Super customer service, they actually answer the phone and call back promptly if they’re not available. Hannah dealt with the quote patiently and efficiently and Adrian was very helpful throughout with technical advice.
The final products, we chose Heritage doors and windows, look stunning. Thank you.
