Will Blackout Curtains Reduce Heat in Your Home?

Image of a sunny window with heat radiating through. During the hot summer, you will find that keeping your home cool and comfortable could be a challenge. Don’t worry. One solution that has been gaining popularity in recent years is the use of blackout curtains. But, will blackout curtains reduce heat in your home? The answer is yes! Let’s find out the reasons together.

Understanding Blackout Curtains

In recent times, out of the demand for environmental protection, functional curtains have developed by leaps and bounds. With the maturity of differentiated fiber technology, the enhancement of textile finishing additives, and the rapid development of weaving technology, heat-insulating and thermal insulation functional curtains continue to emerge.

Blackout curtains are a type of window display that not only obstructs light but also meets aesthetic preferences. They are those curtains that have good heat insulation in summer, heat preservation in winter, and UV protection. How do blackout curtains differ from regular curtains? The greatest benefit of blackout curtains lies in their exceptional insulation capabilities. These thick curtains are specifically crafted to block out ambient light and external warmth. With a dense weave and thick materials, they effectively prevent heat loss during winter and maintain a cool environment during summer. This insulation is further enhanced in curtains with an additional insulating lining layer.

Materials of blackout curtains

After an initial understanding of the concept, then let's talk about the classification of blackout curtains in terms of material. The material is the key to answering the question of whether blackout curtains reduce heat. Usually, they are mainly made of linen blackout fabric, printed fabric material, coated blackout fabric, flame retardant blackout fabric, and jacquard blackout fabric. The material is the most crucial factor for blackout curtains’ thermal insulation. Blackout curtains do this by using a tightly woven, opaque material.

Despite the common material, there is also a special coated fabric, which is mainly a layer of material with special function coated based on fabric by special craftsmanship.

Why do blackout curtains reduce heat in your home?

The scientific principle behind blackout curtains is very simple. Blackout curtains are made of tightly woven fabrics, which can be made through the thickness of the fiber, multi-layer, or with a special coating on the back, so that the natural light and ultraviolet rays can not penetrate the curtains, creating a dark space and an ideal sleeping environment.

The research showed that the solar protection index can reach 60.8% in summer by using blackout curtains. The indoor temperature is 6-12 degrees lower than without curtains. For those who use regular curtains, their indoor temperature is 4-6 degrees higher. In winter, the vast majority of heat radiated from the human body and objects will be reflected by the blackout curtains, and therefore it effectively prevents the heat from being emitted. So the room temperature can be maintained. Both scenes illustrate that blackout curtains will reduce heat in the home. Moreover, we found out that installing blackout curtains on south-facing windows significantly improves insulation.

Other benefit of blackout curtains

Many people use blackout curtains in their sleeping spaces to minimize exposure to morning sunlight and other light sources. The primary use of blackout curtains is to create a good sleeping environment. Because the human body in the dark will begin to produce melatonin, which is a naturally occurring hormone. It helps to regulate your body's circadian rhythm or natural sleep and wake cycle.

However, light affects the production of this hormone, so blackout curtains prevent light interference with the production of melatonin, so you can fall asleep faster and sleep longer.

Around the world, many people use blackout curtains to help sleep. A survey of Norwegian adults found that 63.3% of respondents use blackout curtains. 30 years old or younger use blackout curtains the most, with a slight decline in the use of the elderly population.

Conclusion

Now we know the answer to the question: will blackout curtains reduce heat in your home? The answer is definitely yes! We have interviewed many homeowners about the question of whether blackout curtains will reduce heat in their homes. Many have noticed a significant reduction in indoor temperatures and increased comfort. It’s a trend to install blackout curtains for environmental philosophy now. It contributes a lot to saving energy on air conditioning and reducing carbon emissions.
