Fixed Rooflights vs Opening Rooflights: Which Should You Choose? 

Fixed Rooflights vs Opening Rooflights: Which Should You Choose? 

Choosing between fixed and opening rooflights depends on what you want your rooflight to achieve. Fixed rooflights are designed to provide natural daylight without an opening mechanism, making them a suitable choice when bringing more light into the room is the main priority. 

Opening rooflights are designed to provide ventilation as well as daylight and may be more appropriate for rooms where additional airflow is required. If your space already has suitable ventilation and you primarily want to brighten the interior, a fixed flat rooflight can provide a simple, streamlined solution. 

When choosing your rooflight, consider the room, available roof space, required size, glazing specification and whether ventilation is needed. If you are unsure which option is suitable, our team can provide guidance before you purchase fixed rooflights. 

Frequently Asked Questions 

Are fixed rooflights suitable for flat roofs? 

Yes. Fixed flat rooflights are designed for suitable flat roof applications and provide a way to introduce natural daylight without an opening mechanism. The correct product will depend on the roof construction, required size and installation requirements.

What is the difference between a fixed rooflight and an opening rooflight? 

A fixed rooflight is designed to provide natural daylight without opening, while an opening rooflight can also provide ventilation. If your main priority is bringing more light into a room and ventilation is already available elsewhere, a fixed option may be suitable. 

What sizes of fixed rooflights are available? 

Fixed rooflights are available in a range of styles and sizes, including rectangular options and custom dimensions. The appropriate size depends on your available roof space and the requirements of your project. Check the individual product specifications for available dimensions before ordering. 

re fixed glass rooflights energy efficient? 

The energy performance of a fixed glass roof light depends on the glazing and overall product specification. Energy-efficient glazing can help improve thermal performance while allowing natural daylight into the property. Check the specifications of the individual rooflight before purchasing.

Are fixed rooflights suitable for homes and commercial properties? 

Yes. The collection includes fixed rooflights suitable for a range of applications across residential and commercial properties, including homes, offices and warehouses. The appropriate product will depend on the building, roof construction and project requirements. 

Can I purchase fixed rooflights in custom sizes? 

Selected products are available in custom dimensions, giving buyers greater flexibility when standard sizes do not suit the available space. Check the individual product details to confirm whether bespoke sizing is available for the rooflight you are considering. 

Do fixed rooflights comply with UK Building Regulations? 

The collection states that its rooflights are designed to comply with UK Building Regulations. Specific requirements can depend on the property and installation, so the relevant product specifications and project requirements should be checked before installation.
