Thermal blinds are available in a range of different styles – from roller blinds, vertical blinds and even Venetian blinds. They are a brilliantly effective way to ensure every room in your house is the correct temperature.
Thermal roller blinds are a great asset when it comes to retaining heat inside a room. They are constructed with a layer or multiple layers of thermal material which helps prevent heat loss. However, they will only be effective when they are down, so you'll need to have double glazing as well.
When installed inside the window frame, vertical blinds effectively create a seal on the window that can prevent the hotter or cooler air against the window from circulating in the room. The insulating qualities of the vertical blinds depend entirely on the materials used to make them.
How effective are thermal blinds? Thermal blinds can be extremely effective depending on the type of window and how they are installed and used. The blind will need to be down to be the most effective, so there are no gaps around the edges that lets the warm air escape.
The small gaps in between each slat in Venetian blinds and vertical blinds allows warm air to escape, reducing insulation capabilities.
In general, the lower the U-Value, the less heat loss. Therefore, you are looking to reduce the U-Value of your windows when you install thermal window blinds. In general, a standard double glazed window would have an approximate U-Value of around 2.8 – 2.9.
Blinds made from high quality thermal fabrics are the ideal option for keeping the heat in your home, blackout blinds by their nature tend to be a thicker fabric so if you don't want to go down the route of specific thermal blinds, blackout might be your next best choice.
The simple answer to whether roller blinds cause condensation is this: no. This is because the roller blind is excluded on a pedantic technicality. The technicality is this: a roller blind can't cause condensation because it doesn't produce moisture or heat.
The answer is 'yes', certain types of blinds will trap a layer of air between the fabric and the glass, helping to keep out the cold coming in from your windows. Professionally fitted blinds can be an energy efficient way to keep the heat in and the cold out.
The insulating qualities of real wooden blinds are fairly well-known in terms of their ability to keep the heat on the desirable side of the operation (i.e., the outside in summer and the inside in winter).
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.
But what's the difference between blackout and thermal curtains? In short, blackout curtains are primarily designed to blackout a room by reducing the amount of light that can enter through the window. Thermal curtains, on the other hand, are primarily designed to reduce heat loss from a room's windows.
Blinds with the specially treated thermal fabric prevent heat escaping from your home during winter and reflect solar heat during summer keeping your living space cool. Thermal blinds are great all year round, plus, they are inherently blackout – so they will give you the privacy you need.
Vertical Blinds in fabric or vinyl are the perfect solution for large windows. It reduces heat gain up to 45% when the blinds are closed.
Increasing the temperature in your room, particularly overnight and in the winter, will prevent the build-up of condensation on your windows and walls. This is because condensation occurs when water condenses on a cold surface.
Blinds can't cause condensation due to the fact they do not produce moisture or heat.
A combination of high indoor humidity and a cool outdoor surface collects condensation on the inside of the glass. High outdoor humidity (especially in the morning) and rain can also cause windows to fog up on the outside.
Let's start by clarifying what a 'Thermal Blind' is, for us, it's a blind that is specifically designed to help either trap heat in your room, preventing it from escaping, or to help keep your home cooler in the winter by reflecting sunlight away from your window.
Cellular shades, or honeycomb shades, are one of the most energy efficient window coverings you can buy. They use a series of honeycomb-like cell pockets to trap air around your windows, keeping your rooms warm in the winter and cool in the summer.
Cellular Shades
Cellular shades have the highest efficiency value, making them one of the best choices for window treatments in your home. For optimal light control and thermal performance, opt for the top-down bottom-up style, which allows you to control the amount of sunlight shining in throughout the day.
The best types of blinds that help keep cold out are the ones made from fabric. The ones with slats such as venetian blinds are better for the summer as they allow heat to escape in between the slats. Honeycomb blinds are a type of fabric roller blind that are great insulators as well as sun blockers.
The closer a blind or shade is to the window, the better it will perform as an insulator, so an inside mount blind or shade will provide the most protection from cold drafts.
Closing window blinds can also save energy in the winter. During cold winter nights, heat is lost through windows. Closing the blinds adds some insulation to the windows, reducing heat loss during cold periods. Some blinds also reflect heat back into the room.
