Lock options

Various locking features, including panic bars, are available and other extras such as door stays and closers can be fitted.


The demountable frame allows easy removal of the threshold, transom and overpanel to allow access for large plant. This also makes the VentaDoor® easy to install in areas with restricted access i.e. stairwells etc. Overpanels can be supplied as plain or louvred.


The strength and lightness of the VentaDoor® is achieved by manufacturing the door with a lighter gauge steel and using strategic folding techniques. Its lightweight design reduces the need for fork-lift transportation on site. Minimal space is required for storage.


The door leaf and louvre components are manufactured using Aluzinc®, a steel sheet material with an aluminium/zinc coating. This gives them a high degree of corrosion resistance. Aluzinc® can have a life expectancy of up to 20 years in most environments.

The nature of the coating means that the cut edges ‘heal’ and remain rust-free.
Welding is kept to a minimum to avoid the removal of protective coatings by the welding process. Added strength is given by the use of stainless steel rivets.
The demountable steel frame allows each component to be individually electro zinc plated which increases the corrosion resistance.

By using standard off the shelf components, the VentaDoor® can be offered with reduced lead times.
