How To Choose Energy-Efficient Roof Windows For Your Home

29 May 2023 | Construction, General

‍Are you looking for a way to bring more natural light into your house while saving money on energy costs? While there are many ways to do this, you may want to think about installing roof windows because they are often a great option for enhancing your home’s energy efficiency while also bringing a touch of elegance into your living space.

In this guide, you’ll learn about the benefits of installing energy-efficient roof windows and the factors to consider when choosing the best one for your home. So, let’s dive in.

Benefits of energy-efficient roof windows

Choosing energy-efficient roof windows over standard ones can lead to many benefits in the long run. For starters, they reduce your reliance on artificial lighting by allowing more natural light in, which also contributes to a lower carbon footprint.

They are also much better at retaining heat and regulating your home’s temperature than standard windows, as most energy-efficient roof windows are double or triple glazed, which helps to reduce heat loss, especially during the winter months, while also allowing for proper airflow and ventilation.

This can reduce your reliance on air conditioning and heating systems at home, resulting in greater energy savings. Finally, roof windows can improve the appearance of your home while also making your indoor space feel more bright and spacious, making it more comfortable to spend time in.

Understanding window ratings and certifications

When choosing roof windows for energy efficiency, it’s essential to understand the ratings and certifications that are used in the industry. The most important energy performance rating to look for is the U-value, also known as the U-factor.

The U-value of a window measures its ability to prevent heat loss, or simply how well a unit can keep heated or cooled air inside. In almost all cases, the lower the U-value, the more energy-efficient the roof window will be.

It’s also a good idea to check whether you need a Fenestration Self-Assessment Scheme (FENSA) certification to ensure the roof window installation is covered and adheres to building regulations.

Types of roof windows

There are several types of energy-efficient roof windows on the market, but the majority fall into one of two categories:

Fixed rooflights

These are stationary roof windows and cannot be opened. They are, however, an excellent low-cost option if you want to maximise natural light in your home without the added benefits of ventilation, such as in ceilings.

Manual, or opening roof windows

These roof lights have a handle or a crank that allows you to open them in different ways depending on the window structure. For example, some roof windows can slide, while others can be opened from the top or the bottom.

You can also get electric roof windows that are operated using a remote control or wall switch, making them an excellent option for homeowners who want the convenience of opening and closing their windows, such as those with high ceilings or walls.

Additionally, you can select different glazing options, such as double-glazed or triple-glazed windows, to improve the energy efficiency of your roof windows.

Factors to consider when choosing roof windows for energy efficiency

There are a number of things to take into account when looking for roof windows that are more energy-efficient. First, think about the size and orientation of the roof window itself, as the former can influence how much natural light and ventilation enter your home, while the latter can influence how much sunlight enters your living areas.

Second, take into account the kind of glazing and frame material you want while keeping your budget in mind. The amount of glazing can affect the energy efficiency of your roof windows, while the frame material you choose—such as PVC, timber, aluminium, or steel—can affect their durability and maintenance requirements.

Finally, consider the installation process and cost, as some roof window installations can be complex and time consuming, such as balcony roof windows. It’s always a good idea to work with a reputable installation company that can ensure your roof windows are properly installed while also providing you with all of the necessary paperwork and certifications.

Conclusion and final thoughts

Roof windows are an excellent way to add a touch of elegance to your home while improving its energy efficiency. By letting in natural light and fresh air, rooflights can reduce your reliance on artificial lighting, heating and cooling, which can help you save money and energy over time.

When choosing a roof window, it’s essential to consider the size, orientation, glazing, frame material, installation process, and overall cost.

By considering these factors, you can choose the best energy-efficient roof window for your home and enjoy the many benefits that it provides.
