There are many types of skylights available for properties, including:
Fixed Skylights
A basic, flat, rectangular skylight made of glass or plastic is locked in place. They’re popular for commercial properties because they’re simple and effective at increasing natural light.
This type of skylight represents the most traditional design choice available. It is secured to an upstand on the roof and provides an abundance of natural daylight for the interiors below. For larger areas of glazing, several glass panes can be linked together to provide one large rooflight. With clean, elegant lines and a sleek profile, a static rooflight maximises sunlight, offering outstanding thermal performance – particularly when manufactured to BSI standards with proper thermal breaks and argon-filled glazing units.
Thermal Efficiency Considerations
To ensure optimal thermal efficiency, it’s highly recommended that only static roof lights with thermal breaks be acquired—especially skylights made from aluminium. That’s because aluminium transmits heat and cold temperatures very efficiently, and if the external temperature can control the temperature of the skylight frame, it can create significant condensation and heat loss issues. Modern solutions like polyamide thermal breaks can effectively address these concerns.
| Skylight Type | Key Benefits | Best For | Notable Features |
|---|---|---|---|
| Fixed Skylights | Maximum natural light; superior thermal performance; weather-tight seal | Commercial spaces; residential rooms needing consistent light | Double-glazed argon-filled units; thermal breaks; BSI-certified construction |
| Ventilated Skylights | Natural light + fresh air; automated controls; weather-sensing features | Kitchens; bathrooms; spaces needing temperature control | Electronic operation; rain sensors; wind sensors; 400mm opening range |
| Walk-on Skylights | Dual functionality; structural integrity; maximises usable space | Roof terraces; courtyards; basement lighting | Multi-layered laminated glass; anti-slip treatment; structural engineering certification |
| Pyramid Skylights | Architectural appeal; enhanced light distribution; modern aesthetics | Statement spaces; entranceways; large rooms | 30° pitch design; thermally broken frames; contemporary styling |
| Kerb-mounted Skylights | Superior waterproofing; increased glass area; excellent drainage | Wet climates; renovation projects; larger openings | Raised upstand; sophisticated drainage; enhanced water management |
Ventilated Skylights
These skylights can be opened to provide natural light and ventilation, which is helpful in areas with high humidity or moisture, like kitchens and bathrooms.
Also known as opening roof lights, these are a highly effective solution for those seeking increased ventilation and fresh air for living areas below. The most advanced models are electronically operated by remote control, offering both abundant natural light and clean air combined. From the outside, an opening rooflight looks like a traditional fixed skylight, but chain-driven actuators enable it to open – typically to a maximum of 400mm for optimal ventilation.
Smart Features
Modern ventilated skylights can be equipped with sophisticated weather packs that work with the operating system. These include rain and wind sensors that automatically trigger closure in inclement weather, providing peace of mind and protection for your interior spaces.
Tubular Skylights
Tubular skylights are a cost-effective alternative to fixed skylights. They consist of a roof-mounted light reflector, a highly reflective tube, and an interior fixture. They’re ideal for small spaces where traditional skylights are difficult to install. While they offer a compact solution, they typically provide a different level of thermal performance or natural light transmission than larger glazed units.
For spaces where maximum natural light and superior thermal efficiency are priorities, our SkyView fixed skylights offer significantly better light transmission and temperature control through their advanced double-glazed argon-filled units, making them a more effective long-term investment.
Walk-on Skylights
Designed to be walked upon regularly, internal and external walk-on skylights are a very effective means of enhancing natural light levels in the living areas below. A typical use would be in a courtyard or garden area above a subterranean living space. These skylights sit on an upstand with a gap between the surface and the paved or decked surface.
Safety Considerations
Walk-on roof lights require specialised glazing strong enough to withstand regular foot traffic for comprehensive safety and watertight performance. This structural integrity is essential in meeting Building Regulations. Modern specifications include multi-layered laminated glass with anti-slip treatments for areas that may get wet, ensuring safety and functionality.
Pyramid Skylights
These skylights have a geometrically pleasing shape that channels sunlight from multiple angles, creating a dynamic play of light. Modern designs feature reduced pitches of 30 degrees or lower, resulting in a more unobtrusive external appearance while flooding interiors with abundant natural light.
Design Evolution
Recent design trends have made glazing bars thinner, maximising light transmission while maintaining structural integrity. These architectural statements are available in lantern-style rectangular and square shapes to meet various project requirements.
The best manufacturers utilise thermally broken aluminium frames with double runs of polyamide insulating sections for superior thermal performance.
Kerb-mounted Skylights
These skylights are an excellent choice to prevent leaks and can offer more glass area than deck-mounted skylights. The raised kerb upstand provides excellent water management and can incorporate sophisticated drainage systems for improved longevity.
Dome Skylights
These dome-shaped skylights allow light to enter from multiple angles. They also offer greater privacy and reduce potential glare. While traditionally made from acrylic or polycarbonate, modern versions can incorporate advanced glazing materials for improved thermal performance.
For a superior modern alternative, our pyramid skylights combine striking aesthetics with industry-leading thermal performance, offering up to twice the heat retention of traditional dome skylights while maximising natural light transmission.
Materials and Glazing Options
The most common skylight materials are aluminium, wood, or PVC, with glazing in acrylic, polycarbonate, or glass. Glass is the most popular choice, while polycarbonate is more cost-effective. When considering longevity, aluminium frames can offer nearly twice the service life of UPVC alternatives, particularly when properly thermally broken and powder coated.
Glazing Specifications
For all skylight types, various glazing specifications are available, including:
- Obscured glazing for privacy
- Solar control glazing to minimise solar gain
- Laminated safety inner panes to contain glass if broken
- UV filtering to protect internal finishes and furniture
- Factory-sealed double-glazed units with argon gas filling for superior insulation
Whether you’re renovating or building your property, choosing the right skylight type is crucial for introducing natural daylight effectively into your home. Each style offers unique benefits, and understanding these differences will help you make an informed decision that best suits your specific needs and architectural requirements.
When selecting a manufacturer, look for those with proper certifications and testing protocols to ensure your skylight will provide years of reliable service. Get in touch with the UK’s leading skylight manufacturer – we know our stuff.
