Should you Tilt your Blinds Up or Down for Better Heat Control?

Tilt Your Blinds Up or Down

When looking for the perfect window treatment for your windows, you are often spoilt for choice. There are countless options to choose from for both shades and blinds. Blinds have unique functionality that allows them to tilt their slats up and down for light control. This is one of the main reasons for choosing blinds over shades.

Blinds, Slats & How They Function

Blinds have individual horizontal slats that can be tilted, lowered or raised depending upon your need while shades generally consist of one continuous piece of material that cannot be tilted. They are either raised or lowered to match your requirements. For blinds, there is a lift cord that has strings that are connected to the bottom of the window and are pulled by a cord. If the cord is pulled then the bottom of the blind is pulled up high and if the cord is released then the blind moves down. The blinds must be aligned correctly before they can be lifted. Once the cord is lifted or lowered there is a mechanism for the lift cord to remain stationary. Most blinds have slats that are always parallel to each other and are equidistant from each other. At the same time, all slats can be turned in the same direction.

When the slats are turned such that they are parallel to the window and are all touching, the light from outside gets blocked. If you turn the slats in such a way that they are perpendicular to the window, they allow light to pass through them. There is a rod that helps to rotate the slats up and down. You will find that there are three sets of strings that pass through every slat. While the middle string helps to lower and raise the blinds, the two strings help form a ladder that has a slat on each rung of the ladder.

Blinds Slats Tilted Up or Down

For Privacy
When the blinds are tilted up they allow better light control in the room. It gives you better privacy. When the blinds are tilted down, they could look pretty aesthetically but they provide less privacy as it creates larger gaps between the slats.

For Heat Control for Summer
How you turn your blinds and how the slats are positioned also determines how energy efficient your blinds are for your rooms. Tilting the slats can have different effects on energy preservation and light control in the house. During summer you have the sun rays beating down hard. It heats up everything exposed to it. If your windows are kept open or if window coverings are not positioned correctly then it allows warm air to enter the house and increase the temperature inside. If you are using air conditioners then these have to overwork and use more energy to keep the interiors cool. During summer to keep your homes cool you turn the slat upwards. It will reduce heat gain inside the house and help you control heat better.

When the blinds are tilted upwards, the heat tends to flow upwards towards the ceiling. This is especially prominent on blinds with rounded or curved slats (such as on aluminum blinds). This is the best blind position for summer during the day.

You can tilt the slats down during the hot summer nights to allow warm air to escape into the cool nights and thereby help reduce your cooling costs.

Heat Control for Winter

In winter it is the other way round. You have heaters working round the clock to keep your home warm and cozy to escape the freezing cold outside. If your blind slats are not closed, it will cause warm air to escape outside. This will lead to loss of energy as heaters have to use greater amount of energy to warm up your house. During these months you need to tilt the slats down. When the slats are tilted down the top edge of the blinds is turned down and the rounded side faces the room. This allows the warm air near the ceiling to flow down to where it is needed.

It is not enough that you get the perfect pair of shades for your windows that will help to improve the energy-efficiency of the house. How the blinds are positioned and tilted at different times of the day and during different seasons will ensure optimal utilization of its energy-efficient qualities.
