A ventilation system required legally to improve air quality inside the property.

This is effectively the bottom track of the door. We offer the option of weathered and non-weathered thresholds. For external bi folding doors, we recommend our weathered threshold. This consists of a sunken floor track and a small upstand lip that in turn creates a weather-tight seal. The non-weathered thresholds are flush and have no lip. They ought to be used in internal or sheltered areas.

A standard hinged door sash that can be used without having to open the complete bi-fold. It opens separately from the bi folding system to allow access from the outside. This is a convenient and good safety feature.

Safety glass processed by controlled thermal treatment to increase its strength and durability. It is about four times stronger than normal glass.

When the weight of the bi folding door is supported from the top. Given that the doors effectively hang from the top tracks, this system requires sufficiently strong lintels above the opening to endure the weight of the door.

A form of high-security locking system consisting of a central gearbox, facebar, and shootbolt that extends outward to lock it tight to the frame.

An approved polyester powder-coat paint that is baked onto our aluminium. RAL is a paint industry colour reference; the chart offers 150 colour variations.

A barrier or insulation is placed between the interior and exterior of the aluminium door frame to prevent the flow of thermal energy between conductive materials. This ensures that heat is kept in and cold kept out.

Glass that has been treated with an invisible coating to dramatically reduce heat transfer and to reflect internal heat back into your property.

This locking system bolts the door into the frame and locks at multiple points at the turn of a key. It has a minimum of three locking points that all work simultaneously.

If you want to be able to open a single panel door without having to release all other panels you require what we call a traffic door. For this function, you must choose an odd number of doors to open in the direction required. If it is an even number of doors, you will need to have one panel going the opposite way in order to have a traffic door.

We offer a standard and low threshold option on all bespoke orders. All our stock products come with a standard threshold as normal. This is often referred to as the weathered option because it is weather-rated and thus designed for external spaces. The low-threshold acts as a sunken cill to provide a flush floor level finish. There is no rebate for the doors to seal against and therefore it is not fully draughtproof and requires an external drainage gulley.

There is complete flexibility for you to design the bifolds that suit your needs. You can have all the panels opening the same way, or you can split it so that some open to one side and some to the other side. Please refer to the configurations document for further information.

Imagine you are outside the room looking at the bifold, which way would you prefer for the doors to open and then stack up. Please note, openings are always externally viewed.

Flush casement windows are windows that mimic the traditional wooden windows of period properties. They have much better energy efficiency and lower heating bills and are virtually indistinguishable from timber when ordered in colour or woodgrain white.
