The Perfect Mardome Smoke Vent: Your Decision Matters

When it comes to selecting the ideal Mardome smoke vent for your property or organisation, the choice is yours. With a diverse range of variations available, tailored to suit any specification, you have the freedom to choose from different kerbs, dome shapes, colours, and glazing options. To assist you in making the right decision, below are the details of each variant, equipping you with the information you need to find the perfect vent (AOV) that perfectly meets your requirements.

Kerb or Builders Upstand

When selecting a smoke vent for your property, the first consideration is whether it will be supplied to fit a pre-existing structural, insulated upstand. Alternatively, it can be provided with a 300mm uPVC kerb if there is no pre-existing structural insulated upstand in place. See measurement details in product information.

Double or Triple Skin Glazing

The Mardome Trade range of rooflights can be made in different glazing types, double or triple glazing, with triple glazing offering optimal thermal performance and resistance to condensation. Each glazing type also offers varying U-Values, allowing you to achieve your desired outcome for your building.

Dome Shape and Tint

The Trade Polycarbonate rooflight range can be made in 2 different shapes, either dome or pyramid as per the below. Select the shape that aligns perfectly with your vision and requirements.

Mardome Trade Polycarbonate Rooflights can also be made in different tints. Whether you prefer a clear, opal, or patterned/textured tint, each option brings a unique level of light transmission, allowing you to create the desired ambiance and functionality for your space.

Wind deflectors

Consider including optional wind deflectors to take your airflow to the next level. These wind deflectors are designed to enhance the efficiency of your ventilation system, allowing for smoother airflow and improved aerodynamics. By incorporating wind deflectors into your setup, you can create a more comfortable and efficient environment while reducing turbulence.

Central or Offset Opening

Mardome offers both central and offset opening mechanisms. Not only does this feature enhance ventilation and smoke extraction capabilities, but it also transforms the vent into a convenient access hatch. The offset opening mechanism allows for effortless entry and exit whenever required, with an impressive opening angle of 140 degrees in less than 60 seconds.
