Closed blinds serve to deflect the sun (and so, heat) before it gets into the room, which reduces unwanted solar gain and helps to keep your home cooler in turn.
Smart Home Cooling Tips. Close your blinds and curtains. Keeping your blinds closed during the day will reflect a surprising amount of heat radiating in through windows, especially during the time of day when the sun's rays shine directly on your home.
Yes, blinds are good insulation for windows, regardless of the type of blind you use. This is because the closed blind forms a barrier (that is permeable to various extents depending on the blind), which helps to keep heat in, cold out, and to take the edge off draughts from rattly windows.
In the winter, if you have south-facing windows, let the light shine in. The sun will help heat your home naturally, which takes some pressure off your furnace. For other windows, keep blinds and curtains close during the winter to keep heat inside your home.
The short answer is yes, closing your blinds can help to keep the heat out of your home. When sunlight enters your home through windows, it heats up the air and surfaces inside. By blocking out the sun's rays, you can prevent some of this heat from entering your home in the first place.
Window blinds—vertical (Venetian blinds) or horizontal slat-type (louvered-type)—are effective at reducing summer heat gain and reducing glare, while providing good daylight indoors.
Better winter option: turning the blinds down will help direct heat towards the center of the room, utilizing your resources in the winter. More light: because the blinds are facing down, light can stream in from the sun easier, which will flow towards the center of your living space.
Keep blinds open during the day. Not only will this practice save you some money on energy bills during the winter, but it can also keep you and your family healthier. Read on to find out how sunlight can kill harmful bacteria present in the dust in your rooms.
Fabric blinds are the most effective at keeping the cold out. Venetian blinds with slats, for example, are better for the summer because they allow heat to escape between the slats. Honeycomb blinds are a form of fabric roller blind that works well as both an insulator and a sun blocker.
Your house could be cold due to an old air filter, a faulty furnace, improper insulation, or leaky ductwork. The simple fixes, like replacing an air filter, are relatively easy to complete. However, if the heater itself needs repairs, it's best to call in a professional to take a look and determine the problem.
If your furnace is blowing hot but your home is still cold, it may be a problem with your ductwork. You may have leaky or damaged ducts that are letting hot air escape and cold air in. Sometimes a damper in the system can get miss-adjusted or come loose, thereby inadvertently blocking or reducing airflow.
What Temperature is Too Cold for a House? While everyone has a different tolerance to cold, ideal winter heat settings should generally be at or above 63 °F (17 °C). Excessive cold (anything below 62 °F or 16 °C) in your home can actually raise your blood pressure as your blood “thickens” in the chilly temperatures.
Nighttime. When nighttime hits, placing your blind's slats in the down position is best. When in the down position, your blinds block more incoming light.
Cellular blinds
They're excellent insulators, thanks to their ingenious design which uses hollow honeycomb-shaped cells to help control the temperature in your home. Any heat passing into or out of your home passes through the honeycomb pockets of the cellular blinds, which prevent it from escaping.
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
We recommend settings yours within the 67 to 70-degree range. However, at the end of the day, every homeowner is different and may prefer a slightly higher or lower temperature.
Recommended Temperature When You Are Home
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home. Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won't get enough air.
Energy.gov suggests that 68 degrees is a good room temperature while you're awake at home but recommends lowering it while you're asleep or away.
With all that said, as a general rule of thumb, the ideal temperature for the elderly in a living room is 21°C, or 70°F, and above, and it's a minimum of 18°C, or 64°F, in the bedroom. Bathrooms, meanwhile, should be between 22°C and 24°C, or 71°F and 75°F.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
Overall, white blinds can reasonably be considered to be better in terms of their ability to support an ambient temperature to some degree in both hot or cold weather; they're definitely better than black blinds in this respect if you look at the year-round picture.
