Korniche 6 Pane Bi-Fold Door

Achieving a flush finish

Use our threshold guides (found in the downloads section) to decide the best threshold and sill option for your doors. Its important to remember that if you are looking for a flush finish, this is achieved by the flooring levels that run up to the track and are the responsibility of the homeowner and the architect/builder. Please speak to your builder or flooring contractor and show them the threshold options if you are unsure.

Trickle Vents

Due to new 2022 building regulations, there is a good chance any doors going into new extensions (or even refurbishments) may require trickle vents. If you are unsure, please refer to either your architect or local planning office to see if this is a requirement.

If trickle vents are required, your doors will be supplied with an add-on piece to the head jamb. This is included in the overall size you specify, and gives you some extra clearance to allow for plasterboards internally. The trickle vent itself will typically be installed in the head frame or the add-on itself, although this can vary by manufacturer. If this detail is important to you please ask before placing your order.

Orientation

Always remember when specifying your opening direction that all doors are viewed from the EXTERNAL of the property. For example, if you select a bi-folding door with the doors sliding left, that is the doors sliing left as viewed from the outside of the house.

If inward opening doors are specified, please ensure you have considered any furniture etc. on the inside of the room. This is particularly important with bi-folding doors, which would need to stack inside the room. (Typically, this is not common and they are ordered opening outwards).
