Since 1977, Demers Glass has helped Arizona homeowners find smart, energy-efficient solutions for letting natural light into their homes. Skylights remain one of the most effective and attractive options for brightening up any space. Whether you're building a new home or renovating an existing one, choosing the right skylight can significantly impact lighting, ventilation, and even energy costs.

This comprehensive guide explores the most popular types of skylights, how they perform in different spaces, and what to consider when selecting the right model for your needs. We also address one of the most common homeowner questions: Are skylights energy-efficient? Our goal is to give you clear, expert-backed answers with practical advice to help you make informed decisions.

Fixed Skylights

Fixed skylights are the most common and cost-effective type. As the name suggests, they do not open and are designed solely to allow natural light into the home. Because they are sealed, they are particularly good at preventing air leaks and minimizing maintenance.

Their ability to flood a space with daylight without increasing airflow makes them a perfect match for areas where temperature control is a priority.

Installation Tip: Pair fixed skylights with whole house window replacement projects to maximize daylighting throughout your home.

Ventilating Skylights

Ventilated skylights, also known as operable or venting skylights, can be opened either manually or electronically. These models are especially useful in spaces where air circulation is beneficial, such as kitchens, bathrooms, or laundry rooms.

Modern vented skylights often come with rain sensors that automatically close the unit during inclement weather, giving homeowners both comfort and peace of mind. For example, adding one to a bathroom with a glass shower enclosure can help prevent moisture buildup while bringing in beautiful, natural light.

Key Benefit: They improve indoor air quality while reducing reliance on mechanical ventilation systems.

Tubular Skylights

Tubular skylights, sometimes referred to as sun tunnels, offer an innovative solution for small, enclosed areas where traditional skylights may not fit. These compact systems use a highly reflective tube to funnel daylight from the roof into areas like closets, pantries, and hallways.

Because they require minimal roof alteration and can be installed relatively quickly, tubular skylights are both budget-friendly and energy-efficient. If you're unsure whether a tubular skylight or standard model is best for your needs, read our comparison: Sun Tunnel vs. Skylight: Which One Is Better for My Home?

Ideal Use: Small or oddly shaped interior spaces with no existing windows.

Custom Skylights

Some architectural styles call for skylights that are anything but standard. Custom skylights can be manufactured in a variety of shapes, sizes, and materials to match the unique requirements of your home. From pyramid and dome-shaped skylights to expansive, multi-pane installations, the possibilities are nearly endless.

Though they come at a higher price point, custom skylights offer design flexibility and can significantly enhance both the aesthetics and functionality of a space.

Customer Tip: Ensure your custom skylight includes energy-efficient glazing and a high-quality frame to meet insulation and durability standards.

Glazing and Placement Matter

The performance of any skylight depends heavily on where it's installed and the type of glazing used. South-facing skylights capture the most sunlight, which can be beneficial in winter but lead to overheating in summer. North-facing skylights provide consistent, indirect light year-round.

When it comes to glazing, look for:

  • Double or triple-pane glass for thermal insulation
  • Low-E coatings to reflect heat
  • UV-blocking treatments to protect furnishings from fading

Are Skylights Energy-Efficient?

Skylights have often received mixed reviews when it comes to energy performance. Poorly installed or outdated models can contribute to heat gain in the summer and heat loss in the winter. However, modern skylights have come a long way in offering better energy performance through advanced technologies.

Factors That Improve Skylight Efficiency:

  1. ENERGY STAR certification
  2. Insulated glazing units (IGUs)
  3. Proper roof integration and flashing
  4. Built-in blinds or solar shades

Additionally, consider pairing your skylight upgrades with window tinting solutions to reduce solar heat gain even further.

Choosing the Right Skylight for Your Home

Every home has unique needs. The right skylight for your property depends on several key factors:

  • Room function: Does the room need ventilation?
  • Roof slope: Not all skylights are compatible with low-pitch roofs.
  • Sun exposure: Are you looking to increase heat in winter or reduce it in summer?
  • Energy goals: Are you trying to qualify for energy efficiency rebates or certifications?

Use a professional contractor to assess your home’s structural and energy efficiency needs. Proper installation ensures you’ll benefit from all the advantages a skylight can offer—without unnecessary energy loss or water intrusion.

Beyond the Skylight: Enhancing Light and Efficiency

To further improve your home’s lighting and thermal performance, consider these additions:

  • Light diffusers to scatter harsh direct sunlight
  • Motorized shades for light control and privacy
  • High-performance window glass for nearby windows (explore our glass guide)
  • Insulated skylight wells to limit thermal bridging
