Aluminium or insulated blanking plates can be mounted to the rear. In addition expanded aluminium mesh birdguards or perforated fly screens are available. Each of these can be fitted internally during, manufacture. Head, cill and jamb flashings in aluminium alloy to BS EN 485 can be prodiced to suit opening requirements.

Mitred Corners

Internal and external mitred corner units are available to enable a continuous appearance of the louvres to be maintained around changes of direction.


Louvre modules are supplied completely assembled either with integral box frames or concealed mullion supports, depending upon application. For applications requiring large areas of continuous unbroken appearance, installation time is minimised as all louvre blades are precisely factory pre-assembled onto supporting pre-punched mullions for ease of on site fitting by the fixing contractor.


Maintenance should be carried out in accordance with McKenzie-Martin’s recommendations.
