Mardome Smoke Vent AOV Polycarbonate Rooflight

The Mardome Smoke Vent AOV Polycarbonate Rooflight is a certified automatic opening rooflight designed to provide effective smoke and heat exhaust ventilation while allowing high levels of natural daylight into the building. Fully compliant with EN 12101-2, it is suitable for use as part of a life safety smoke ventilation strategy in commercial, residential, and public buildings.

Manufactured from high-impact, UV-stabilised polycarbonate, the Mardome AOV offers excellent durability, weather resistance, and long-term performance. It is suitable for installation on flat and low-pitch roofs up to 15° and can be specified for both new-build and refurbishment projects.

Mardome Smoke Vent (AOV) Size Options

The rooflight is available in a wide range of standard sizes to suit smoke ventilation calculations and roof layouts.

Standard sizes (mm) include:

1050 × 1050, 1200 × 1050, 1200 × 1200, 1350 × 1050, 1350 × 1200, 1350 × 1350,
1500 × 1050, 1500 × 1200, 1500 × 1350, 1500 × 1500,
1650 × 1050, 1650 × 1200, 1650 × 1350, 1650 × 1500, 1650 × 1650,
1800 × 1050, 1800 × 1200, 1800 × 1350, 1800 × 1500, 1800 × 1650, 1800 × 1800.

Glazing Options

Different glazing options are available to suit insulation requirements and building use.

Double skin polycarbonate – Used in lightly to moderately heated buildings where improved thermal performance is required while maintaining good daylight transmission.

Triple skin polycarbonate – Used where enhanced insulation and reduced heat loss are required, such as offices, residential buildings, schools, and other continuously occupied spaces.

Tint Options

Tint options are used to control daylight levels, glare, and privacy within the building.

Clear polycarbonate – Used where maximum light transmission is required, such as stairwells, corridors, and escape routes.

Opal finish – Used to diffuse daylight and reduce glare, making it suitable for offices, classrooms, and healthcare environments.

Patterned finish – Used where diffused light and increased privacy are required, commonly in residential developments or buildings overlooking neighbouring properties.

Shape Options

The rooflight is available in two low-profile shapes to suit different roof layouts and design requirements.

Low-rise dome – Used for general flat roof applications where a simple, cost-effective solution is required.

Low-rise pyramid – Used where improved daylight spread is required across internal spaces or where a more architectural appearance is preferred.

Kerb Options

Kerb options are available to suit different roof constructions, exposure levels, and waterproofing requirements.

Installation onto a builder’s upstand – Used where a suitable existing upstand is already in place, commonly on refurbishment projects or where upstands are formed as part of the roof build-up.

Builder’s upstand with wind deflectors – Used on exposed roofs or taller buildings where wind effects could impact smoke ventilation performance.

300 mm PVC waterproofing kerb – Used for standard flat roof constructions where a factory-manufactured kerb is required to achieve consistent insulation and waterproofing height.

300 mm PVC kerb with wind deflectors – Used on high-level or exposed buildings where reliable smoke exhaust performance is critical in fire conditions.

Actuator Options

Actuator options allow the rooflight to be configured to suit access, operation, and smoke ventilation requirements.

Central actuator – Used for standard AOV installations where the rooflight is dedicated to smoke ventilation and balanced opening is required.

Offset actuator – Used where the rooflight may also be used for maintenance access or where clear internal access beneath the opening is required.
