If you’ve ever asked, “Are skylights energy efficient, or will they just make my home hotter or colder?” — you’re not alone. It's one of the most common questions we hear at Regal Glass, especially from homeowners who care about comfort and energy savings. The short answer? Yes — modern skylights can be very energy efficient, as long as you choose the right design, materials, and placement. In this post, we’ll break down what makes a skylight energy-efficient, answer real-life questions, and show you how to bring natural light into your space without wasting energy or increasing your utility bills.

🔍 Search Questions, Answered

Will a skylight make my room hotter in summer or colder in winter?

Not if you choose one with energy-efficient glazing like Low-E glass and proper installation. The right skylight can help regulate indoor temperatures.

Do skylights reduce electricity usage?

Absolutely. By bringing in more daylight, you rely less on artificial lighting, especially in kitchens, living rooms, and hallways.

Can a skylight qualify for energy tax credits?

Some solar-powered and Energy Star-rated skylights do! Check with Regal Glass Group to see if your model is eligible.

Are venting skylights energy efficient too?

Yes — especially solar-powered vented skylights, which let you cool your home naturally without turning on the AC.

💡 What Makes a Skylight Energy Efficient?

At Regal Glass Group, we offer skylights that meet or exceed the latest energy performance standards. Here's what to look for:

✅ Low-E Glass (Low-Emissivity)

This invisible coating reflects heat while allowing light to pass through. It helps keep heat inside during winter and outside during summer.

✅ Double or Triple Glazing

Multiple layers of glass create insulation, just like energy-efficient windows. This minimises heat transfer and stops condensation.

✅ Argon or Krypton Gas Fill

These non-toxic gases between glass panes act as extra insulation, blocking temperature shifts and UV rays.

✅ Thermal Break Frames

Our skylights include thermally broken aluminium or composite frames, which prevent heat from transferring through the frame.

✅ Solar Shades or Blinds

Optional built-in shades help manage glare and temperature on sunny days, without compromising natural light.

🛠️ Placement & Orientation Tips

Installing even the most efficient skylight in the wrong spot can reduce performance. Here's how to optimise:

North-facing skylights give steady, indirect light and minimal heat gain.
South-facing ones can provide passive heating in winter — great for colder climates.
An east-facing location brings morning light without too much heat later in the day.
A west-facing location may cause more heat gain in the afternoon — pair it with blinds or glazing.

💡 Pro Tip: Skylights with integrated rain and heat sensors (available from Regal Glass Group) help manage light and ventilation automatically — an innovative and energy-efficient choice.

🏡 Benefits Beyond Efficiency

Installing an energy-efficient skylight offers more than just a lower electric bill. You'll also enjoy:

Improved mood and focus from natural daylight
Better indoor air quality (with vented skylights)
Increased property value and modern aesthetic
Eco-conscious living by reducing your carbon footprint

At Regal Glass Group, we believe energy efficiency should also look beautiful. That's why we only stock skylights that are both functional and stylish.
