Shapes & Sizes

Size range

Em-Vent Smoke Ventilators are available in an unrivalled range of over 55 sizes in square, rectangular and circular shapes. Most of these are available from stock.

Glazing

The Em-Vent can be supplied with polycarbonate glazing or an insulated solid cover. The glazing element can be chosen from the wide range of options in the Em-Dome rooflight range such as single, double, triple or quad skin with a clear, opal diffused, bronze or HeatReflect finish in dome or pyramid profile. The key benefit of the polycarbonate glazing is that it allows natural light into the building. All polycarbonate glazing has an impact strength 250 times greater than glass and is AA fire rating to BS476 Part 3. Whitesales offer a 10 years warranty against discolouration and loss of impact strength.

The solid insulated cover can be provided as mill finish aluminium or polyester powder coated to any standard RAL colour.  It is available insulated with a 32mm panel or a 64mm thick panel providing exceptional thermal insulation values.
