Choosing the Right Velux Skylights: Types, Benefits & Installation Tips

Natural light transforms interior spaces—adding warmth, energy efficiency, and a sense of openness that traditional windows can’t always deliver. As a leading distributor of Velux skylights, Skylights2Go offers a wide range of skylight solutions to fit every home or commercial building. But with so many models and features available, how do you choose the right skylight for your space?

In this article, we break down the most popular types of Velux skylights, their unique benefits, general size guidelines, and helpful installation considerations to help you make a confident decision.

1. Fixed Skylights

What They Are

Velux Fixed Skylights are non-operable skylights designed to bring in abundant daylight without ventilation. They’re ideal for spaces where light is desired but airflow isn’t required—such as hallways, stairwells, closets, or vaulted ceilings.

Key Benefits

  • Affordable, low-maintenance daylighting solution
  • No moving parts = reduced mechanical wear
  • Energy-efficient glazing with UV protection
  • Great for hard-to-reach or high-ceiling applications

Common Sizes

Velux fixed skylights come in a range of standard sizes, from 14"x30" to 46"x46", with custom sizes also available. The size you choose will depend on your ceiling height, rafter spacing, and desired light spread.

Installation Tip

For maximum effect, place fixed skylights in areas where natural light is limited but ventilation is not necessary. They're often the easiest to install and integrate seamlessly with flat or sloped roofs.

2. Manual Venting Skylights

What They Are

These manual venting skylights open manually using a control rod or crank. They provide both daylight and natural ventilation, helping reduce moisture buildup in high-humidity areas like bathrooms, kitchens, or laundry rooms.

Key Benefits

  • Combine light and airflow
  • Energy-efficient when closed
  • Ideal for single-story homes or rooms with easy access

Size Options

Manual skylights come in multiple dimensions, with common sizes including 21"x45" and 30"x46". Make sure you have clearance for the opening mechanism.

Installation Note

Mounting these on lower roof slopes or within reach makes daily use practical. Velux provides optional insect screens and blackout shades for added functionality.

 

3. Electric Skylights

What They Are

Velux Electric Skylights open and close at the push of a button, offering the convenience of motorized operation. They're perfect for spaces with high ceilings or for homeowners who want effortless control.

Key Benefits

  • Remote control operation
  • Rain sensor auto-closes skylight during storms
  • Integrates with Velux blinds and smart home systems
  • Excellent for kitchens, great rooms, or vaulted spaces

Size Guidance

Available in a variety of sizes, including wider or double units for maximum daylight. Electric skylights require access to power during installation, so plan accordingly.

Pro Installation Tip

Ensure electrical access and proper flashing kits are planned in advance. Pairing with light-filtering or blackout blinds gives you total control over sunlight and privacy.

4. Solar Powered Skylights

What They Are

Solar Powered “Fresh Air” Skylights from Velux function similarly to electric models, but draw their energy from a small solar panel mounted on the exterior. No hard wiring is required.

Key Benefits

  • Energy-efficient with no wiring needed
  • Qualifies for federal solar tax credit (30% in many cases)
  • Rain sensor auto-close
  • Remote control included

Size Considerations

Offered in standard Velux sizes, solar skylights are perfect for retrofits or green building projects. Installation is simplified compared to electric models.

Installation Tip

Best suited for sunny roof areas. Since they don’t require an electrician, solar skylights can reduce labor costs during installation.

 

5. Tubular Skylights (Sun Tunnels)

What They Are

Velux Sun Tunnels are compact, highly reflective tubes that channel daylight into spaces with limited roof access—like closets, hallways, or interior bathrooms.

Key Benefits

  • Delivers natural light to tight or enclosed spaces
  • Minimal roof penetration required
  • Available in flexible and rigid tunnel formats
  • Budget-friendly solution

Common Sizes

10", 14", and 22" diameters are the most common. Rigid tunnels provide more intense light, while flexible versions are great for maneuvering around attic obstructions.

Installation Tip

Sun Tunnels can usually be installed in a few hours. Ideal for small spaces where a traditional skylight won’t fit.
