Polycarbonate Vent / Access Options
There are four different methods of ventilation and an access hatch option to satisfy varied requirements.
 |
Where the rooflight is to be used as a means of access on to a roof, a fully opening frame can be specified for mouting either direct to a builders timber kerb, or in conjunction with PVC kerbs. They are available from either our Thermadome rooflight range or our Stardome rooflight range. There are many different sized access hatch frames and polycarbonate domes available ex-stock from our Thermadome rooflight range, however we can manufacture them to your specific sizes from our Stardome rooflight range. |
 |
Permanent trickle ventilation is provided by means of spacer washers inserted in the fixings. A gap of 5-10 mm can be provided around the complete perimeter without comprimsing security or weather protection
Spacer washers are provided free of charge upon request with our Thermadome rooflight range regardless of the size of the rooflight. |
 |
Louvre vents are fitted to two opposite sides as standard. All four sides of the rooflight may be fitted with vents if higher levels of airflow are required. The fully adjustable louvre vents are operated by means of a hooked rod. The louvres are protected from the elements by an external weather cowl. Louvre vents can be fitted to any size rooflight from our Thermadome rooflight range, and we can offer an extremely similar method from our Stardome rooflight range should you require a non-standard size. |
 |
An extractor fan can be fitted where natural ventilation is insufficient. These high performance extract fans are designed for ventilating internal bathrooms and other small rooms.
They are available in both our Thermadome and Stardome ranges in almost any sized rooflight. |
 |
Our rooflights can be supplied fitted with hinged opening frames, with a manual spindle operated by a winding rod, or an electric motor.
Opening frames are available with our without kerbs from our Thermadome range, or manufactured to your specfic sizes from our Stardome range. |
