Challenges of Harsh Winter
There are regions of the world that experience particularly harsh winters. From the month of October the mercury starts to dip and by end of December and early January temperature often drops below the freezing point. It can go as low as -15 degree to -20 degrees and even more. it is frigid and the biting cold winds can make stepping out a painful affair. At the end of a long day outside, people hurry back to enjoy the cosy warmth of a well heated home. With the heaters working round the clock they help to warm your chilled bones. As you watch the snow fall and turn the world outside white you are thankful for the little luxuries of life that allows you to enjoy comfort.
Energy Loss through Windows
While a well service heater is the most precious possession during these months, the very purpose of warming up the air inside the house is defeated if the warm air escapes the house allowing cold draft to chill up the air. This will cause energy loss and you have to face rising cost of electricity bills. This is because with warm air escaping the house, the temperature drops and to maintain the required temperature the heaters have to consume more units which will cause the cost to go up. Most of the energy loss happens through glass doors and windows because glass is a very poor insulator. The warmed up air is light and drift out easily. To prevent this from happening it is important to cover up your windows effectively with insulating blinds. A flimsy curtain or simple cotton blind is ill-equipped to pose a barrier to the warm air. Vertical blinds are a great option but may not be suited for the most extreme temperatures. What your windows need are insulating window treatments or thermal blinds.
What are Thermal Blinds? What are the Benefits?
A thermal blind is designed to trap the heat in your room during winter and keep your home cooler in summer by reflecting sunlight away from your windows. They are energy efficient and extremely effective in maintaining temperature inside the house. Energy costs are reduced significantly. As thermal blinds are made of layers they help to trap the air between the blind and the window pane and block the flow of air from outside to the inside.
Thermal blinds are effective in blocking out light inside the room which is an added advantage of these blinds. Bedrooms in particular require complete darkness for a good night’s sleep.
They can also block out outside noise and hence create a soothing and calm ambiance inside the house.
What is R-Value?
Effectiveness of blinds in preventing escape of warm air is often measured by R-value of blinds. R-value is a measure of resistance of a particular material to heat flowing through it. So, higher the R-value, greater the heat resistance. Blinds with low R-value will not insulate well.
Thermal blinds with high R-value can help to reduce heat transfer by almost 62% which is significant.
Ideal R-Value of Thermal Blinds
So what is the ideal value of thermal blinds? For normal blinds average R-value is around 2.5 which is quite low. For thermal blinds he R-value should be up near 5.0 mark. Thermal roller blinds, Double Cellular shades boast of an R-value of 5 which is comprehensive enough to insulate your homes well against heat loss. Anything below 4.5 is not deemed ideal for homes facing a excessively cold winters.
If you are contemplating investing in thermal blinds to combat freezing cold winters make sure that the R-value is significantly high to serve your purposes.
