How Thermally Efficient Are Roof Lanterns?
When working on a home improvement project, it’s worth keeping energy efficiency in mind. Today’s homeowners are very switched on, and while the aesthetics and functionality of their houses are important, they also tend to think about long-term costs. Any kind of product that can potentially reduce their bills will be appealing, especially if those savings offset the installation costs.
Here at Whitesales, we pride ourselves on making energy-efficient glazing. Whether it’s a roof light, lantern, continuous glazing, or anything in our catalogue, we work hard to deliver top-quality products. Let’s take a closer look at the thermal qualities of roof lanterns and see how effective they are.
Do Roof Lanterns Make The House Cold?
Maybe it’s because metal roof lanterns are cold to the touch, but there are people who firmly believe that roof lanterns are poor at trapping heat. In the past, we’ve spoken with homeowners who think installing a roof lantern is akin to making a big hole in the ceiling and that they are likely to make household temperatures plummet.
Nothing could be further from the truth. Modern roof lanterns and skylights have benefited from years of technological advancements and now perform just as well as any other type of window. They’re fitted with double glazing as standard which is perfect for reducing heat loss and can even be upgraded to triple glazing if requested.
Roof Lantern U-Values
As an example of this, let’s consider one of our more popular choices, the em.glaze Skyvu lantern. You can see a full list of its attributes on the dedicated webpage, but the key figure to remember now is the U-Value; 1.3 W/m²K. On the off-chance that you’re not familiar with this term, a U-Value is the rate of heat transfer, and the lower the number, the better.
To put this into perspective, within new Building Regulations, the required U-Value of a cavity wall is 1.6 W/m²K and for a double glazed window, it’s 1.2. The required U-Value for any type or rooflight, including a lantern is 2.2 W/m2K which means that our em.glaze skyvu lantern is well below the regulations. The idea that roof lights are poor at retaining heat simply isn’t true. Everything you get from Whitesales has been stringently tested and you can rely on our products to meet the expectations of a knowledgeable public.
So if your customers ask about thermal efficiency, you can put their minds at rest. You can depend on Whitesales to deliver eco-friendly roof lanterns that result in warmer homes, lower heating bills and less carbon emissions.
If you’d like to know more, we’d love it if you contacted us. Our expert staff will be able to pass on all the guidance and accreditations you could need. Alternatively, if you’d like to speak with us about your next project, you can request an online quote. We can’t wait to work with you.
