Bi-Folding Doors

We manufacture timber bi-folding doors to any configuration and any size. Our timber doors are pre-finished using spray applied microporous paints in any colour, or a choice of over 70 different stain combinations, to suit any building or architecture.

Product Specifications

Over recent years we’ve witnessed a steady increase in demand over the more traditional French or sliding patio doors. Hardly surprising, as bifolds are very stylish and when fully ajar offer approximately 90 percent clear opening for easy access.

Having invested considerable time and effort perfecting the optimum gearing system for our new range, we’re confident that they meet the high standards of performance and versatility our customers have grown to expect from Glyngary. Choose from a variety of timbers which can incorporate DGU’s or veneered door panels (internal use only), or indeed can be RAL colour matched to customers requirements.

As well as exterior folding doors, we offer an internal version with veneered panels. These are ideal to separate living areas such as a living room from a dining room or commercially, to divide up conference rooms in a hotel.

If you’re looking to set yourself apart from the competition, Glyngary’s exclusive designs and superb quality will go a long way to helping you achieve this.


The Energy Efficient DGU’s are made with the following products:

4mm Low Iron glass (external)
4mm Low E glass (internal)
16mm ‘warm edge’ spacer bar
MATCHING integral duplex bar positioned behind the surface mounted astragal bars to give the appearance of separate DGU’s
Argon filled DGU’s

Draught Proofing

Fully draught proofed using compressible seals.


Locking is available in many varieties of multipoint locking, including ‘handle-less’ options. We use a very high quality Bi-folding hardware system, which can be hung from the head for smooth ‘weightless’ operation, or can also have a system where the gearing runs on the cill (if the structure in which they are being fitted cannot take the weight to the head).
