What to Put on Windows to Keep Heat out and Light

Are you having a hard time sleeping and wondering what to put on windows to keep heat out and light?

The free heat energy we get from the sun can make you feel very uncomfortable in your own house and especially in the summer.

Keeping the doors and windows closed and leaving the air conditioning unit on all day and night might not cut it with the high summer temperatures.

That is why people often turn to other easy options to keep the heat out such using blackout curtains, cardboard, and sunblocking window covers among others.

So let’s discuss some of these options that are readily available.

Here are some effective ways through which you can reduce solar heat and help you sleep or relax in the house without feeling like you are in a sauna.

1. Sunlight Blocking window cover

Sunlight blocking window covers are specially designed to completely seal off the light and heat.

They tend to be more effective than shades, blackout curtains, and blinds because they seal tightly even along edges of the window frame where heat and light tend to pass through.

Blackout EZ window covers are a perfect example of these sunlight blockers. They are white on the outside to reflect light while the inside is black to complement your room décor.

They are very easy to install and do not require any measurements or rods and hooks. Simply place the Blackout EZ over the window and then press the edges so as to seal it.

You can remove and reinstall them every day and the adhesive-backed hook and loop Velcro will still stick even in the extremely hot in summer or cold in the winter.

These blackout shades are particularly useful for people who work at night, kids napping, and home theaters.

2. Blackout curtains

If you don’t like the idea of sticking something on to your windows, you can use blackout curtains.

These curtains are made of a heavy or thick fabric that helps to block light, reduce outside noise, and insulate against heat and cold.

High-quality blackout curtains can reduce the amount of heat getting into the house by about 99% and reduce noise as well.

For instance, Eclipse thermal insulated curtains block 99% of light and minimize noise by 40% from the outside environment.

Blackout curtains also come in handy during winter to trap in heat and prevent the cold from getting in; hence, keeping the room warm.

3. Shades and Blinds

Shades are perfect for keeping heat out by blocking harsh UV rays and sunlight.

They also help to keep the room ventilated to allow the free flow of air in and out.

Window shades come in different fabrics, weaves, and colors. You can choose the one you want based on the purpose of shades and where you want to install it.

For instance, fabric shades like this SUNFREE Cellular Honeycomb window shades are the most suitable if you want to insulate your home in the summer or winter.

If you are a DIY person, then this option will appeal to you.

Another tactic to keep heat out is to cover the window using cardboard.

To install it, simply cut it to the required size and secure it on the window using scotch tape.

The black rubber shelf liner works in the same way as the sunlight blocking window cover.

Since black color is known to absorb heat more than other colors, the black rubber shelf liner will help to absorb the heat and keep the room cool.

Covering the windows with a reflective material such as tinfoil or aluminum foil can help to not only keep out light but also heat.

Both aluminum and tin foil tend to reflect heat away; hence, keeping the room cool.
