Why do windows lose heat?
The reason we lose so much heat out windows is because glass is a poor insulator. It’s well accepted that a good way to reduce heat loss out your windows during the colder months is to invest in quality curtains and blinds. Read on to find out why romans and honeycombs have the best insulating properties and how to make rollers perform at their best, plus a few other considerations about placement for good effect.
What happens when the temperature is colder outside than inside?
When temperatures are colder outside than inside, glass conducts the heat from inside the house to the outside where it disappears. The air next to the glass inside, having lost its heat, becomes cold and dense and falls to the floor drawing in new warm air from above. This cycle continues until you lose all your warm air outside.
Do roman blinds cover the whole window?
Thermal lined roman blinds are also an excellent choice. They cover the entire window space leaving little room for heat to escape. You have a choice of fabrics to suit your aesthetic and insulating needs, and they can be constructed with a number of different linings to ensure you get the insulation and blockout properties appropriate for your room. Just remember they need to fit snugly against the wall to create that seal and stop cold air leaking through.
Do blinds need to be lined?
Any gap and the thermal effects of the blind, even if it’s well lined, will be negated. For this reason, we recommend fitting the blind outside the window frame.

Lining is essential for improving insulation so if this is what you need from your blinds, choose and option that can be lined, such as a roller roman blind.
HOW DO BLINDS CONTROL THE HEAT?
While your choice of fabric certainly affects the overall insulation value of your blind, what’s more important is the fitting. Window coverings provide insulation by creating a seal against the window, reducing air movement to and from the glass and effectively trapping hot or cold air. In winter, air close to your windows will quickly cool and sink, so any gaps at the bottom of your blinds will allow the cold air to circulate back into the room.

For honeycomb blinds prices tend to start at about $70, while roman blinds are more expensive at a minimum $160. You should expect to pay a little extra for blockout fabrics, as more materials and processes have gone into their production.
Why are roller blinds so popular?
Roller blinds are popular because they are modern, easy to maintain and safer than roman blinds, however they aren’t the most efficient for thermal purposes.
What is window covering?
Window coverings are items added to existing windows to improve energy efficiency, reduce glare or natural lighting, provide privacy, or enhance the appearance or comfort of a home. Window coverings include:
What are exterior shutters made of?
Exterior shutters and shades are usually made of a variety of materials, including fabric, wood, steel, aluminum, or vinyl. They are most effective at reducing solar heat gain.
Why do you need to keep window coverings closed in summer?
In the summer, you may want to keep window coverings closed to reduce heat gain. For natural light, open those window coverings that don’t get direct sunlight.
Why do you need two draperies?
Two draperies hung together will create a tighter air space than just one drapery. One advantage is that the room-side drapery will maintain around the same temperature as the interior space, adding to a room's comfort.
How to reduce heat loss in a drapery?
For maximum effectiveness, install a cornice at the top of a drapery or place the drapery against the ceiling. Then seal the drapery at both sides and overlap it in the center. You can use Velcro or magnetic tape to attach drapes to the wall at the sides and bottom. Taking these steps will further reduce heat loss.
What is an insulate cellular shade?
Insulated cellular shades are made of pleated materials that are designed to fold up, accordion-like, usually at the top of the window, but sometimes at either the top or the bottom. Insulated shades contain one or more air layers in a honeycomb cross-section. Some can be adjusted from the top, from the bottom, or both.
How much energy is lost through windows?
About 30% of a home's heating energy is lost through windows. In cooling seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat. Window coverings can help with this energy loss and lowering energy bills. The exact savings will depend on the type of attachment, the season, the climate, and how the attachment is used. In addition to the window coverings, storm windows with low-e coatings and/or multi-layer glazing are effective at improving thermal performance of windows and reducing solar heat gain.
How do cellular shades get their name?
For manufacturing cellular shades, multiple layers (such as two or more) of fabrics are pleated together for forming cells or channels. Since these air chambers look like honeycombs, they get their name, honeycomb blinds, and shades.
What is the best blind for privacy?
If you are looking for blinds that, apart from better insulation, also provide greater privacy – then cellular shades would be the right choice. They are better equipped to block out light more efficiently as compared to other blinds. This becomes possible because of the multiple layers they have that effectively block out light which means it is difficult to look through these blinds from outside. For an additional level of privacy, select the double cell option with blackout or room darkening fabrics.
What is honeycomb blind?
Honeycomb blinds (also called cellular shades) are the preferred choice for many due to the advantages they provide, ranging from better insulation to privacy and light control. However, they do have their own disadvantages that you need to know about before actually purchasing them for your home.
How many pockets are there in cellular blinds?
Cellular blinds and shades can have one, two, or three pockets or cells in every layer. If there are more cells, there will be higher number of air layers and you will be getting better insulating value. But, these will be costlier than blinds that have fewer cells in every layer.
Why is it so hard to clean honeycomb blinds?
Difficulty in Cleaning. Over time, honeycomb blinds will get dusty and dirty, making it necessary to clean them. Cleaning these cellular shades can become a problem because of their honeycomb structure. It can be tricky to properly clean each and every cell in the cellular blind.

R-Value Is the Most Common Insulation Rating.
What is R value?
R-Value Is the Most Common Insulation Rating. Basically, R-value measures how well a material reduces energy (heat) gain or loss. It’s a measure of thermal resistance, used most commonly with building and construction materials. The higher the R-value, the more energy you are saving!
What is the openness factor of solar shades?
What you’ll want is solar shades with is to choose the right “openness factor.”. The lower this number is (range from 1% to 14% openness), the more light the shades reflect out. A 1% openness factor, for example, means 99% of natural light gets blocked out.

What does R value mean in blinds?
“R-Value” measures the resistance of a particular material to heat flowing through it. The higher the R-value of any given insulator, the greater its heat resistance. Blinds with lower R-values don’t insulate as well.
How to calculate R value?
To calculate the R-value of a given material, a test is conducted inside a heat flow meter apparatus . The material is placed between a cold and hot plate. Heat then flows from the hot to cold plate via conduction, convection, and radiation, and the testing device measures the flow of all three. The R-value is then calculated after the test completes.
