Energy is beginning to cost more, and household and workplace energy users like air conditioning systems and artificial lighting are starting to be questioned by far more homeowners and business owners.
In recent years, the number of people installing daylighting systems to reduce their energy consumption has massively increased. Both homeowners and businesses are enjoying the benefits of natural light – mainly a significant reduction in energy costs.
Despite this, there are several myths about daylighting and heat – from daylighting systems letting in heat during summer to daylighting systems letting heat out from the house in winter – that remain frustratingly common.
In this blog post, we’ll bust four of the most common myths about natural light and heat to help you learn more about how daylighting systems can work with, instead of against, your air conditioning or heating system and home insulation.
Myth 1: Natural light means unpredictable heating bills
It’s true that natural light transmits heat, but today’s modern skylights feature high-tech glazing that blocks both infrared and ultraviolet light. This means you’ll receive none of the skin damage caused by UV radiation or any of the heat it produces.
Our Coollite glazing system blocks up to 85% of infrared light and 99.9% of all ultra-violet light so that your home or workplace’s temperature remains predictable and steady, no matter how sunny it might be outside.
Myth 2: Daylighting means uncomfortable daytime heat
Another frustrating myth about daylighting is that it leads to serious daytime heat that’s difficult to control. The truth is that modern daylighting systems are built to let in light, not heat, and use a variety of methods to reduce heat transfer.
For example, our Thermal Break and Barrier are designed to reduce heat loss and heat gain through the aluminum used in skylight construction. This means steady daytime temperatures and very little heat gain in summer, even when it’s sunny.
Myth 3: Skylights let warm air escape during cool winters
What’s worse than an uncomfortably hot home in summer? The answer is obvious – an uncomfortably cold home in winter. A major fear of homeowners and businesses is that installing a skylight will cause warm air to ‘escape’ during the winter months.
The basic science behind this myth isn’t entirely unbelievable. Since warm air rises to the top of a contained space like a living room or office, it’s conceivable than it’s likely to escape through a skylight or other thin surface.
However, the same thermal insulation technology that’s used to keep heat out from your home during summer can keep heat in your home during winter. Our Thermal Break and Barrier reduce all heat transfer, keeping warm air inside your home.
Myth 4: Daylight makes your air conditioner work overtime
Since sunny days are warmer than cloudy days, most of us associate sunlight with heat, even when this isn’t always the case. Thermal insulation means that sunlight won’t always heat your home, even when it’s exceptionally bright and intense.
Because of this, you needn’t worry about your air conditioner working overtime to counteract the heat produced by a skylight. With the right UV and IR blocking, your skylight will illuminate your home without changing its ambient temperature.
