Bi-Folding Doors

Bi-Folding Doors and Glazed Screens

Browns Joinery manufacture the ultimate in external solid timber bi-folding doors and screens. Opening up a wealth of new design possibilities. Browns bi-folding door systems have been designed to maximise the flexibility of a rooms living space, removing barriers and enabling the home owner to appreciate an indoor outdoor experience by fully opening up exterior walls.

We manufacture our bi-fold doors in a range of hardwoods from sustainable sources. Predominantly Oak , Sapele, Idigbo and Accoya which can be finished in our workshops in a range of clear oils to enhance the beautiful grain of wood or apply a full factory opaque paint finish.

Our screens and bi-folding door systems are available in a wide range of glazing specifications and coatings. We offer 24mm double glazed and 44mm triple glazed toughened or laminated safety units as standard. Using Planitherm glazing our range of coatings includes tinted glass, solar control and self-cleaning.

Browns use the highest quality German manufactured running gear and security locks. Using the best possible track systems enables us to offer ultra smooth running mechanisms and easily adjustable hinges for fine tuning.

How do they arrive?

As standard  all of our bi-folding doors are fully assembled and running as a complete set in our workshops as part of the manufacturing process prior to delivery.

Once they are complete the doors are removed from the hinges and the simple four part frame is unscrewed.  Each element is wrapped for protection and ready for delivery.

This pre assembly process reduces site time dramatically and we always have positive feedback that our bifolds have been fitted with ease.

Pre-Glazing is not always required, however we are happy to offer this service upon your request, along with factory finished treatment of the doors.
