Will a Skylight Heat Up My Home?

Will a Skylight Heat Up My Home?

Sometimes all a room needs to freshen it up is the proper lighting. Many people consider installing skylights in their home, whether it’s in the office, kitchen, or living room. We’ve had a few customers ask us in the past, “will a skylight heat up my home?” – and this is a valid question. However, there are a few things to consider when weighing in on whether a skylight will heat up your home or not.

Size of the skylight.

That might sound like a large number, but this translates to just $19 extra in cooling bills per year, based on a rate of 8 cents per kWh. And considering the benefits of skylights in your home, an extra $20 a year might not seem like such a big deal.

It’s estimated that a skylight allows greater heat loss in winter than does a traditional wall window. However, this problem can be solved by using high-grade skylights and materials that are well above code.

Size of your home.

It’s also important to consider the size of your home and how many skylights you want to have installed. Not only is it expensive to keep your home at a comfortable temperature via heating and cooling, but you also need to keep your home well-lit. While skylights might cost a few more dollars a month in heating and cooling costs, it might also save you a few dollars in lighting and electricity expenses. With a well-placed skylight, you can do without turning on any inside lights for hours longer each day – both an eco-friendly and cost-saving alternative.

Preventing a Skylight from Heating Up Your Home

Positioning

Proper positioning of your skylight upon installation is critical, and your contractor should place it in an area of your roof that gets ample shade in summer. Vented skylights are also a great option if you want to be able to open and close it to let heat escape.

Protective Coating and Glazing

A professional installation crew will likely recommend that you get a covering for your skylight to eliminate heat gain and increase privacy. Skylight shades, UV protective coatings, and safety glazing are a few options to avoid heat gain.

Insulation

Make sure that your installation contractor properly insulates your skylight so you suffer less heat loss. Proper insulation and installment will also protect you from moisture entering your home via the skylight.
