Skylights are roof windows that allow natural light to enter a building. Adding skylights enhances lighting, ventilation, and creates an open, airy atmosphere. With recent advancements, modern skylights also improve energy efficiency in homes and commercial spaces.
There are three main types of skylights commonly installed across the UK:
- Fixed skylights – These permanently fixed windows cannot be opened for ventilation. They allow maximum light but offer limited airflow control.
- Ventilating skylights – Designed for ventilation, these operable windows are adjustable to regulate indoor air quality and temperature.
- Tubular skylights – Featuring a reflective tube that transports sunlight, these compact skylights distribute light evenly into smaller interior spaces.
Below is an in-depth guide on the unique characteristics, pros and cons of each skylight variety. We also answer some frequently asked questions homeowners have about skylights.
Fixed Skylights
Definition and Characteristics
Fixed skylights, as the name suggests, are non-operable roof windows that remain permanently closed after installation. Key qualities include:
- Permanent installation – Fixed securely in place, they cannot be opened or shut for ventilation.
- No ventilation capability – Designed solely for natural lighting, they do not allow indoor air exchange.
Advantages of Fixed Skylights
Installing fixed skylights offers certain benefits:
- Increased natural light – They maximize sunlight penetration without moveable parts that can obstruct light passage.
- Energy efficiency – High-performance glass and insulated frames reduce heat gain/loss for improved efficiency.
Disadvantages of Fixed Skylights
Potential downsides to consider include:
- Limited ventilation – The lack of operable windows restricts fresh air intake.
- Potential heat buildup – Sunlight and inadequate airflow can cause interior spaces to overheat.
Proper site planning with external ventilation sources can help mitigate some of these cons, a practice embraced by roofers in Stroud.
Ventilating Skylights
Definition and Features
Ventilating, or operable skylights feature openable windows to control ventilation. Distinctive attributes:
- Designed for ventilation – Allow fresh outside air to circulate in and out.
- Operable for airflow control – Manually or automatically adjustable to preferred positions
Ventilation functionality sets these skylights apart from fixed types. State-of-the-art models have built-in blinds, rain sensors and can integrate with home automation systems.
Advantages of Ventilating Skylights
Key benefits ventilating skylights offer:
- Improved ventilation – User-controlled operation circulates exterior air as required.
- Regulation of indoor temperature – Adjustable windows prevent overheating by releasing warm air.
Allowing fresh air intake provides healthier indoor air quality and balanced climate control.
Disadvantages of Ventilating Skylights
Potential limitations to factor in:
- Installation complexity – Motorized mechanisms increase initial setup requirements.
- Higher cost compared to fixed skylights – More intricate operable parts mean added expenses.
While pricier, the ventilation capacities ventilating skylights provide enhance comfort and air quality considerably.
Tubular Skylights
Definition and Unique Characteristics
Tubular daylighting devices, or tubular skylights, have a distinct shape and function compared to fixed and ventilating types. Defining qualities:
- Compact design with a reflective tube – Features a roof dome that captures and redirects sunlight downwards via mirrored inner lining.
- Suitable for smaller spaces – Distribute natural light effectively in confined areas traditional skylights cannot.
These innovative light tunnels transfer sunlight through angled tubes using almost no energy.
Advantages of Tubular Skylights
Tubular skylights advantages include:
- Efficient light distribution – Reflective tubing transfers maximum brightness to dim interiors.
- Cost-effective for certain applications – Affordable solution for small, windowless rooms.
Disadvantages of Tubular Skylights
Possible tubular skylight drawbacks:
- Limited in size and light output – Cannot illuminate larger spaces with expansive skylight needs.
- Challenging to install in some roof structures – Angle requirements may restrict placement possibilities.
For confined rooms like hallways and bathrooms, tubular skylights are an optimal energy-efficient choice.
Frequently Asked Questions (FAQs)
What factors should be considered when choosing a skylight?
Roof structure and slope, Pitch, materials and orientation impact options. South-facing roofs allow maximum light exposure. Climate considerations, Insulation and glazing specifications based on local temperatures, precipitation and UV levels. Energy efficiency, High-performance glass, gas fills and blinds to control solar heat gain and insulation.
Evaluate individual roof conditions along with local climate and efficiency needs. Custom-designed solutions deliver optimal skylight performance.
Can skylights be installed in any type of roof?
Compatibility with different roofing materials, Such as shingles, slate, tile metal and flat single ply membranes and Structural considerations, Additional reinforcements for heavy snow loads or high winds if required.
With precise roof opening measurements, crews cut perfect openings and expertly waterproof flashings during installation.
Are skylights suitable for all rooms in a house?
Ideal rooms for skylight installation – Living rooms, dining rooms, hallways and upstairs bathrooms benefit enormously from natural overhead light. and Considerations for bathrooms and kitchens – Moisture resistance and minimizing glare on reflective surfaces needed here. Avoid placing directly over shower areas.
Evaluate each room’s activities along with window and lighting placement to determine if skylights help meet its needs.
How to maintain and clean skylights?
Regular cleaning practices, Wash glass several times per year using soft cloths and mild cleaners to remove dirt and debris buildup. Inspection for leaks and damage, Check flashing seals and glass condition annually. Reapply weatherstripping or caulking if required.
Follow manufacturer maintenance guidelines for ventilating skylight moving parts and motors. Have professionals address any glass cracks right away.
What are common misconceptions about skylights?
Skylights causing excessive heat. Modern glazing options like tinted glass and integrated shades prevent overheating. Vents also release warm air. Potential for leaks and water damage. Advanced flashing and sealing methods provide watertight skylight installations that integrate seamlessly into the roofline.
Reputable brands offer robust warranties against moisture infiltration or thermal issues. When properly installed and maintained, skylights are a smart, reliable way to fill interiors with natural light.
