Polycarbonate Domes & Pyramids - Vent & Access Options

Below we explain the four different methods of ventilation and an access hatch option to suit various requirements.

Access

Polycarbonate Dome RooflightsFully opening frames can be mounted direct to a builder’s timber kerb, or in conjunction with a PVC kerb, to allow access through the skylight onto a roof. These skylights can be found in our or Stardome collection.

We can manufacture polycarbonate domes and hatch frames to your required size from our Stardome collection. There are also various sized polycarbonate domes and hatch frames available ex-stock in our Thermadome collection.

Electric Ventilation

When natural ventilation is inadequate an extractor fan is fitted. The fans are designed specifically to ventilate small rooms such as internal bathrooms.

Extractor fans are available in nearly every sized skylight in both the Stardome and Thermadome collections.

Permanent Trickle Ventilation

Spacer washers are provided free of charge upon request with our Thermadome collection whatever the chosen size of your skylight.

The space washers are inserted into the fixings to provide permanent trickle ventilation. A gap of 5-10 mm around the complete perimeter is provided, without compromising weather protection or security.

Hinged Frames

All skylights can be supplied fitted with a manual spindle operated by a winding rod, an electric motor or with hinged opening frames. Opening frames from our Stardome range can be manufactured to your specific size requirements. They are also available without kerbs from our Thermadome collection.

Louvre Vents

As standard, Louvre vents are fitted to two opposite sides. If a large amount of airflow is required vents can be fitted to all four sides of the skylight.

The Louvre vents are operated by a hooked rod and are fully adjustable. An external weather cowl protects the vents from all weather.

Louvre vents are compatible with all skylights in our Thermadome collection. If you require a non-standard size we can offer something very similar from our Stardome collection.
