One of the fastest, simplest, and least expensive ways to answer the question of how to insulate windows to keep heat out is to add
The trick is to use the right type of window shades to block the heat and to install them as close to the glass as possible to get the maximum benefit. For insulation purposes, cellular or honeycomb shades are the most effective. The honeycomb shape helps to trap air, reducing your solar heat gain.
By installing window shades or blinds, hanging a curtain rod and using lightweight curtains, applying a film to your windows, putting up plastic sheeting, or installing storm windows, you can keep the sun's heat out and the cool air in.
Apply Heat Reducing Film
With roughly 30 percent of ambient heat coming into your home through the windows, one quick and easy fix to keep your home cool is to apply a reflective, heat-reducing window film to regulate the temperature.
Using Tin Foil Or Cardboard
Tinfoil, or aluminium foil, is a common and inexpensive way to blackout your window.
Yes. Emergency management agencies specifically recommend using “aluminum foil-covered cardboard” between windows and drapes to reflect heat back outside.
Similar to the wet towel trick, ice is another expert-approved way to cool your room effectively. To do so, Beatrice explains that you should place a bowl of ice in front of your fan. 'The air will circulate through the ice, and as it does, it will pick up the cold temperature of the ice,' she says.
For instance, choosing lighter curtains, voile or blinds in a lighter colour could help to reflect the sun's rays out of the room, so it's worth keeping these closed. If you have dark fabric curtains then it's probably best to keep them open, as dark colours will draw in the heat and could leave the room even warmer.
If you are in a pinch, bubble wrap is an excellent insulator for summer windows. Simply spray a light mist of water on your windows, and lay bubble wrap against them to act as another layer of glass. The bubble wrap will stick as long as you need, and it works to keep the hot out and the cold in.
Method 1: Face cloth or small towel
If possible, use water in a bowl filled with ice cubes to make it as cool as possible. Wring the cloth out so that it's damp, not dripping wet. Lay the cloth over the fan. As it blows the air out, it'll circulate through the cloth and the air will feel cooler.
Hanging a wet sheet in front of an open window cools the warm air as it enters your home, and is a great way to cool down your home without a fan.
Why does household aluminium foil have one dull side and one shiny side? SO THAT the shiny side can reflect the heat on to the item to be cooked, using a long-established scientific principle that shiny surfaces reflect heat and light.
The Pros of Aluminum Foil on Windows
If you choose this method, it can be a cheap and effective way to keep your house cool. Foil can block up to 95% of the sun's rays and reduce heat gain inside your home. It can also provide privacy and prevent unwanted light from entering your rooms.
The Cancer Council in Australia suggests that darker colors absorb UV rays, which helps block them from your skin. That's why dark blue, black, and dark red are the best colors for sun protection compared to white or pastel colors of the same fabric.
If you touch a single glazed window on a hot day, the glass will feel quite warm. This is because double glazing has an inert gas between the two panes of glass, which is a poor transmitter of heat.
Blackout window film will completely block out the visible light spectrum. It won't, however, solve your summer overheating issues.
