In warmer months, three-quarters of the sunlight that shines through standard, double-pane windows enters the house to become heat. Adding window treatments, fixing broken and leaky windows, and choosing new, Low-E glass window panes designed to reduce heat gain can keep you comfortable with less wasted power.
Windows account for almost half of your home's heat gain in the summer. Be sure to: Shade all sunstruck windows with shade screens, awnings, trees and shrubs on the outside and window tints or film, blinds, shutters or drapery on the inside.
Installing blackout blinds over your windows is a good way to prevent sun heat from getting in. Blackout blinds are opaque, so they don't let any light pass through. They are also available in a wide variety of colors and designs, so you can choose the right ones for your home.
Yes. Emergency management agencies specifically recommend using “aluminum foil-covered cardboard” between windows and drapes to reflect heat back outside.
Block the heat
Shade windows and walls using external coverings, like blinds, awnings or large potted plants. Plant deciduous trees that cast shade over your home in summer, but still let the sun shine through in winter.
'However, one mistake people make is by placing the foil on the inside of the window. It is really important to be careful to place the tin foil on the outside of your windows rather than the inside to prevent the glass from getting too hot.
Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.
Window film is a popular alternative to shades or blinds for solar control. It's a thin laminate you can install on your home's interior or exterior glass surfaces. Offered in various shades and reflectivity options, these films provide flexibility in controlling the sunlight coming through your windows.
Using Tin Foil Or Cardboard
Tinfoil, or aluminium foil, is a common and inexpensive way to blackout your window. It's a great option to go for as it's airtight and there's no way to see through it, so covering your window with tin foil is an effective way to achieve total darkness for easier sleeping during the day.
Upgrading your windows
To reduce heat loss through windows, the installation of double / triple glazing can significantly reduce any losses. Generally, the gaps between the panes of glass are filled with air. Heat loss is reduced as air is a poor conductor of heat.
Install storm window inserts. Storm window inserts are clear inserts that look just like a traditional window but are installed inside the window jamb, and over older, single-pane windows to reduce heat loss. They're light and easy to install and require no nails or screws.
The same tactics you use to insulate your windows in winter can be used for the summer, including using thermal curtains to block heat, closing the blinds on hot days, and weather-stripping. Solar window film is another add-on option that you adhere to the glass itself.
The short answer is yes – blackout blinds block sunlight, making them one of the best ways to keep a room cool. Keep your blinds closed all day and you'll find there's a noticeable difference in room temperature – and the more sunlight your blinds block out, the cooler the room will be.
Cover Your Window With Aluminum Foil
Yes, this is probably the least expensive and easiest way to blackout your windows. Simply cut foil squares to the sizes of your window panes before securing them in place with painter's tape.
Water is a one-of-a-kind substance for many reasons. An obvious one is its unique ability to absorb heat. Water is able to absorb heat - without increasing much in temperature - better than many substances.
Insulators: Non-metal objects are used to slow down the transfer of heat. Different materials are better insulators than others. Good insulators include: wood, cloth, Styrofoam, cork, and plastic. (Glass and air also act as insulators.)
Which Side of The Foil Goes Up? The shiny side should be down, facing the food, and the dull side should be up when cooking meals wrapped or covered in aluminum foil since it has a shiny and dull side. This is due to its greater reflectiveness, the shiny side will reflect more heat radiation than the dull side.
Typical cardboard boxes have low thermal conductivity meaning they are able to keep things cool when hot outside and vice versa. The properties of cardboard prevent the transfer of heat from one object to another.
