NOTES
Door Handing
Single
The handing is defined by viewing the door from the pull side. If the hinges are on the right hand side, it is a right hand door. In the same manner, the left hand door is one with hinges on the left hand side.
Double
The handing of a double door is based on the first opening leaf. Viewing from the pull side, if the hinges of the primary leaf are on the right hand side, the door is defined as a right hand door.
Choosing a door
External Door
An opening outward lipped door with a cill and weather canopy is the best choice. The lip protects the latches and bolts. It is harder to pull a door off than to ram it inward. It is much better for weather proofing and it saves internal spaces.
If it opens inward, a flush door with cill and weather board is better for the weather proofing.
Fire Escape Door
If fire regulations require a minimum clearance add 126mm to the width and 63mm (no cill) to the height to arrive at the structural opening required.
Special Doors
Apart from Zintec steel, doors can be manufactured and supplied in aluminum, stainless steel 304 or 316.
Special jamb profiles can be supplied to suit the shape of the opening.
