Our new Heritage bi fold door has been designed to work in perfect harmony with our existing Heritage door and window range. Offering a traditional stepped profile detail with slim sightlines.
The Heritage bi fold door is a versatile alternative to classic Heritage French doors with side lights and to standard bi-fold doors
(see the full range of bi-fold-doors here).
Delivering the perfect combination of retro steel style design with modern strength and exceptional thermal performance our Heritage bi fold door system is capable of opening up an entire wall to integrate outdoor and indoor living space.
...trumps the steel-type systems on thermal performance and cost.
The grasp of the importance of design and quality of manufacture from the Marlin Team is second to none.
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!
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.

Thank-you Marlin Windows for a great job! You designed and built all the windows in our renovation project including sliding doors and bi-folds with care and consideration. From our first contact with Adrian through to the final fitting, the service was exceptional...
