With summer fast approaching, many people are considering how to keep the home cool in the hot weather. One suggestion is to use blackout blinds. But do blackout blinds keep the heat out? And how can blackout blinds help to reduce indoor heat build up?

What are blackout blinds?

Blackout blinds are specially designed to block out all sunlight, which can be very beneficial for bedrooms and children’s bedrooms, as they can help to create a darker environment. These blinds typically feature thick, opaque fabrics or materials with added blackout linings that prevent light from passing through. 

So, do blackout blinds keep the heat out?

While blackout blinds are mainly designed to block light, they can also help reduce heat to a certain extent. When exposed to direct sunlight, windows can act as conduits for solar heat gain, leading to increased indoor temperatures. As a result, blackout blinds, with their light-blocking properties, can reduce the amount of solar heat transmitted through the window, by effectively preventing sunlight from entering the room.

The effectiveness of blackout blinds in reducing heat particularly depends on the specific material and construction. Some blackout blinds are manufactured with reflective coatings or backing, which aids in reflecting a significant portion of the sun’s rays, minimizing heat absorption. Additionally, certain blackout blinds incorporate insulating features, such as multiple layers or thermal linings, which provide an additional barrier against heat transfer. These insulating properties can be particularly useful during hot summer months in the UK, helping to maintain cooler indoor temperatures.

What are the important considerations for maximum heat reduction?

While blackout blinds can contribute to reducing heat, it is important to consider certain factors for optimal results. 

Firstly, the color of the blinds can significantly impact heat absorption. Dark-colored blackout blinds tend to absorb more heat, whereas lighter shades reflect a greater amount. As a result, choosing lighter colors or reflective coatings can help maximize the heat reduction potential.

Another crucial aspect to consider is the installation and fit of blackout blinds. To ensure the most effective heat reduction, it is essential that the blinds are properly installed, covering the window completely. Any gaps or areas where light can leak through will diminish the blinds’ ability to keep heat out. Properly fitted blackout blinds with snug edges and minimal light leakage will enhance their heat reduction capabilities.

Further heat reduction measures

While blackout blinds can certainly help reduce heat, they are most effective when used in conjunction with other cooling strategies. Utilizing additional measures such as window films, or external shading devices can significantly enhance the overall heat reduction in your home. These combined efforts create a comprehensive approach to mitigating solar heat gain and maintaining a cooler indoor environment.
