Threshold Options For Commercial Hinge Doors

French Doors and hinge doors are part of every building. What most people don’t realise is that there are many sill or threshold options available depending on the opening requirements (inwards or outwards), floor heights and weather proofing requirements. Below are some cross sections a brief description for each type of sill.


Type A – Standard Open Out Threshold:
Our most common threshold which is usually used only for opening outwards doors. This sill offers superior weather proofing because the hinge door compresses against a seal on the threshold. The finished floor on the inside can match the top of the threshold, but the outside must be slightly lower so the door can still operate normally.

type-a


Type B – Open In Or Out Sill:
The advantage of this threshold is that it very flat which makes it easier to recess into the floor. It can be used on both inward and outward opening doors. The disadvantage of this sill is that it’s not as weather proof as Type A because the door has nothing to seal against. On request we can fit a brush seal to the bottom of the doors which brushes against the threshold to help with sealing.

type-b


Type C – Alternative Open In Threshold
This alternative open in sill offers superior sealing to Type B because the door panel compresses against a seal. It can’t be made flush with the floor due to its design. The sloped edge on the outside is designed to facilitate water away from the building.

type-c


Type D – Wheelchair threshold option 1:
This wheelchair threshold is designed to meet Australian requirements for the disabled. The inside is 15mm higher and is meant to butt flush with the internal floor. No subsill is usually used on this threshold so these doors need to be suitably under cover.

type-d


Type E – Wheelchair threshold option 2:
This threshold is very similar to Type D, but is designed to sit straight on top of the floor.
