Key Takeaways
- Skylights add natural light and can make rooms feel larger and brighter.
- Venting skylights can improve airflow and help reduce heat and moisture buildup.
- Energy-efficient skylights may include Low-E glass, insulated panes and argon gas fills.
- Fixed skylights provide light only and work well in rooms with existing ventilation.
- Tubular skylights bring sunlight into small or narrow interior spaces.
- Common skylight frame materials include vinyl and aluminum, as well as wood-clad and composite options.
- Tempered and laminated glass offer durability, safety and energy-efficiency benefits.
- Proper installation and flashing are important for preventing leaks and improving performance.
- Roof pitch, room placement and sun exposure should be considered before installation.
Benefits of Skylights
Skylights are installed in the roof to allow daylight into interior spaces. Depending on the style you choose, they can also improve airflow and help reduce the need for electric lighting during the day.
Natural Light
Skylights can increase the amount of daylight in rooms that may not have enough wall space for traditional windows. Adding natural light can make smaller rooms feel brighter and more spacious.
Ventilation
Ventilating skylights can open to allow fresh air into the home. These models are commonly installed in upper rooms for heat and kitchens and bathrooms for moisture.
Efficiency
Modern skylights are available with features that help reduce heat transfer and improve indoor comfort such as:
- Low-emissivity (Low-E) glass coatings
- Double- or triple-pane glass
- Argon gas-filled glass panels
- Solar-powered shades and controls
Design Appeal
Skylights can add architectural interest and create a more open feel in living rooms, stairways, bedrooms and other interior spaces.
Types of Skylights
There are several types of skylights available, each designed for different rooms, roof styles and ventilation needs.
Fixed Skylights
Fixed skylights provide natural light and can be less prone to air leakage than some venting models when properly installed.
Best for:
- Hallways
- Living rooms
- Stairwells
- Rooms that already have adequate ventilation
Venting Skylights
Venting skylights open to provide fresh air and can help reduce humidity and heat buildup. Some models operate manually, while others use electric or solar-powered controls.
Best for:
- Bathrooms
- Kitchens
- Finished attics
- Bonus rooms
Tubular Skylights
Tubular skylights, also called sun tunnels, use a reflective tube to channel sunlight from the roof into smaller interior spaces. These skylights work well in areas where a full skylight may not fit.
Best for:
- Closets
- Hallways
- Laundry rooms
- Small bathrooms
Skylight Materials and Glazing
Skylights are available in several frame and glazing options.
Frame Materials
Common skylight frame materials include:
- Vinyl
- Aluminum
- Wood-clad frames
- Composite materials
Each material offers different benefits related to durability, maintenance and insulation.
Glazing Options
Most residential skylights use tempered or laminated safety glass. Acrylic and polycarbonate glazing are also available on some models.
Glass skylights typically offer:
- Better clarity
- Improved energy efficiency
- Greater scratch resistance
- Better UV protection
Skylight Installation Considerations
Before purchasing a skylight, consider:
- Roof pitch requirements
- Roof framing and available space
- Sun exposure and room orientation
- Local building codes
- Energy efficiency ratings
Professional installation is recommended for most skylight projects to help ensure proper flashing, waterproofing and roof integration.
