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.
Close your curtains at night
During the day, your windows let in more radiant energy than gets out; sunlight can enter through the glass, but the window is opaque to the infrared radiation trying to escape.
Closing curtains at night can reduce heat loss by up to 17 percent. According to the U.S. Department of Energy, using curtains with thermal lining can reduce heat loss by up to 25 percent. Using curtains with white plastic backings can reduce heat gain by up to 33 percent.
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.
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.
Closing curtains at night traps that heat in your home, and you'll be able to turn the thermostat down and use less heating. Both of these methods reduce the strain on your home's heating and air conditioning system, saving significant energy and money.
How Curtains Provide Insulation. Good curtains stop cold air from entering your home by creating an air gap between the room and the window. Ideally, they also prevent any flow of hot and cold air which would create a draft.
Curtains offer better insulation and soundproofing.
In warm weather, however, blinds beat curtains in energy efficiency. Because blinds leak more heat from a room, they also decrease indoor heat gain more efficiently in the summer, by around 45 percent, which can lower your AC bills.
For heavy-duty heat blocking, you'll want thermal drapes that are made with thick materials like polyester and microfiber. These also resist moisture and will minimize it from accumulating in between the window and curtain.
Thermal curtains feature a layer of acrylic foam between the double or triple layers of fabric to provide insulation, making these curtains ideal for winter months or drafty windows. Thermal curtains can also dampen sound, block out sunlight, and reduce energy bills.
Hang Thermal or Blackout Curtains
After you identify the windows or doors that need additional insulation, you need to hang the right curtains to keep cold out. Thermal or blackout curtains are ideal for cold and drafty windows. Thermal curtains are thick, heavy curtains that contain a layer of acrylic foam.
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.
Blackout curtains can trap heat in during the winter and keep light and heat out during the summer. 10-25% of thermal energy loss goes out the windows. Blackout curtains can curtail this loss by a 25%, reducing your utility bills and greenhouse gases.
Curtains and Drapes
During summer days, you should close draperies on windows receiving direct sunlight to prevent heat gain. Studies demonstrate that medium-colored draperies with white-plastic backings can reduce heat gains by 33%.
The best way to winterize your windows is to add a sealed layer of plastic or glass over the window. And the cheapest, easiest way to do this is by installing an interior window insulation kit. Duck brand Shrink Film Window Insulation Kit and 3M Window Insulator Kit are two readily available options.
The reasons your house is cold even with the heat on could be because of poor insulation, your furnace not working properly, rooms with high ceilings, or your heating system doesn't cover the whole house. Each of these issues can prevent your home from properly heating.
Drafts are caused when a house's warm air leaks out and gets replaced or even pushed out by that sneaky, cold outside air. Not only does can this make you uncomfortable in your own home, it also makes your heating less efficient.
Blackout curtains are made from a lighter triple weave fabric which is designed to block out light, compared to Thermal curtains which are made from 3 layers of thick fabric, in most case using 100 % cotton, polyester, or wool, and to protect them from UV rays, the back part of the curtains are coated with acrylic foam ...
Thermal curtains are an extra layer of insulation you can use to make your home more energy efficient. The best thermal curtains consist of multiple layers of fabric with thick padding that prevents air from circulating from your window into your home.
Thermal curtains create a dead-air space between the window and the room, which reduces the amount of air infiltration and transfer of heat. By installing an insulating curtain over a window, heat is kept inside during the winter. During the summer, heat from the sun is reflected back to the outside.
