Blackout curtains and shades will reduce the amount of heat which is transferred via your windows by as much as 24 percent, keeping the rooms where they're installed cooler in summer and warmer in winter. This will allow you to use your heating and cooling system more efficiently and save energy.
Black and white are the colours that you might be wondering about which colour will give your room a cooler temperature. Well, the answer is white curtain colours keep the room cooler than a black coloured curtain fabric because the colour white reflects the thermal energy and black absorbs it.
Things to consider:
Sunlight will fade dark curtains. If unlined, during summer, a darker curtain will absorb heat and radiate it.
These are probably the rooms that get little sun during the day. To help keep all rooms in your house cool, you can: close pale-coloured curtains – closing dark curtains and metal blinds can make rooms hotter. keep windows closed when it's hotter outside than inside, but open them if the room gets too hot.
Curtains help with heat retention by limiting the flow of air between the warm and cold areas of a room. Even double-glazed windows will afford heat with a chance to escape, but a set of heavy curtains will form a barrier that'll limit the flow of air from the main room to the window.
Closing your curtains as soon as dusk falls will maximise your house's potential to retain that heat.
Drapes, curtains and blinds enable you to control the amount of sunlight that enters the room. If you keep them closed completely, you can block the light and heat coming from the sun. You might want to consider window treatments with a light-colored or reflective backing as they are known to work best.
Blackout curtains and shades will reduce the amount of heat which is transferred via your windows by as much as 24 percent, keeping the rooms where they're installed cooler in summer and warmer in winter. This will allow you to use your heating and cooling system more efficiently and save energy.
The clever use of blinds, curtains, and other window treatments can help keep your house cool and your bills in check. The Department of Energy says the smart management of window coverings can reduce heat gain by up to 77 percent. (And, as a bonus, these same practices can reduce heat loss in the winter.)
Because curtains fit the exact size of the window, they are the most efficient for keeping rooms cool. They won't let in gaps of sunlight or add the bulk of extra material to your interior.
During the warmer summer months, they have the ability to reflect heat and prevent it from entering a room. During the colder winter months, blackout curtains can help keep the room's heat from escaping through the windows, saving you money on heating costs.
There's a lot to love about blackout curtains: They keep the light out so you get a great night's rest, they help keep your home cool in summer and warm in winter (saving you money and helping the environment), and they can even reduce noise if you live in a busy area.
If the home already is thoroughly insulated and natural light is the main issue, go with blackout curtains; if outside light doesn't bother you but you're plagued with drafty windows, thermal curtains are the better choice. Still, both curtains can work to reduce both issues at least a little bit.
Close the Curtains During the Day, and Use Dark Ones
This will help you cool down your room without AC. If your window catches a lot of direct sunlight, using dark or blackout curtains will prevent the rays from overheating your room during the hours when the sun is most active.
Insulated Cellular Shades
For leaky windows, insulated cellular shades, sometimes called honeycomb shades, are one of the two most effective window treatments for keeping out the cold air and keeping in the heat.
In heating seasons, tightly installed cellular shades can reduce heat loss through windows by 40% or more, which equates to about 10% heating energy savings.
Yes. Emergency management agencies specifically recommend using “aluminum foil-covered cardboard” between windows and drapes to reflect heat back outside.
