Keep your home cooler in summer with heat-resistant window decoration

Sunny days are wonderful, but indoor temperatures can rise quickly. Rooms with large windows or lots of sunlight can become uncomfortably warm during summer. That is why many people look for ways to keep their home cooler without immediately investing in air conditioning.

Did you know that the right window decoration can play an important role in this? By reducing sunlight and heat directly at the window, indoor temperatures are easier to control.

But which window decoration actually helps reduce heat? And what should you consider when making the right choice? In this article, we explain how heat-resistant window decoration works and why pleated blinds are often a smart choice for summer.

How does heat enter your home?

On warm days, the sun shines onto the glass of your windows. This causes the glass to heat up and transfer warmth into the room. The larger the window surface, the greater the effect of solar heat gain on the indoor temperature.

Does window decoration help against heat?

Yes. Almost every type of window decoration offers some degree of heat protection. Window decoration creates an extra layer between the window and the interior space. This helps block part of the heat before it spreads through the room.

Which window decoration offers the best heat protection?

The heat-resistant effect differs per type of window decoration. This is mainly determined by the material and by how closely the window decoration fits against the window frame.

Fabric-based window decoration, such as pleated blinds and roller blinds, offers better insulating performance than products made of wood or aluminium. Fabric creates a more closed layer in front of the window, making it harder for heat to enter the room.

The fit against the window frame also plays an important role. Window decoration that is placed tightly in or onto the frame leaves less space for warm air to pass around the product. This helps maintain the insulating air layer between the window and the window decoration. Framed window decoration fits more closely against the frame than free-hanging window decoration. As a result, fewer gaps are created and the insulating effect is improved.

Heat-resistant window decoration from KeJe

Would you like to keep indoor temperatures under better control during warm summer days? KeJe offers various types of window decoration that help keep heat outside and contribute to a comfortable indoor climate.

Splendid Pliss

The Splendid Pliss is one of KeJe's most heat-resistant window decoration products. This pleated blind is integrated into an aluminium frame that is mounted onto the window frame without drilling or screws. Thanks to this installation method, the window decoration fits tightly against the window, leaving hardly any gaps for heat to pass through.

This pleated blind is easy to operate thanks to its integrated operating bar. You can adjust the blind from top to bottom as well as from bottom to top. This allows you to create the ideal balance between daylight, privacy and heat protection.

Fixed Window Plissé

The Fixed Window Plissé works according to the same principle as the Splendid Pliss, but is permanently installed with drilling and screws instead of being magnetically attached to the window frame. Thanks to the fixed installation, the Fixed Window Plissé fits tightly against the frame and remains securely in place. This makes it particularly suitable for sloping roof windows, where you want to regulate both daylight and heat effectively.

Day 'n Night

The Day 'n Night combines two fabrics in one system, allowing you to switch easily between different positions. For example, you can choose a combination of translucent and blackout fabric. Thanks to the integrated operating bar, you decide how much daylight enters the room and how much heat you want to keep outside. This makes it easy to adjust the window decoration to the time of day and your personal preferences. This pleated blind is also installed without drilling or screws and is securely attached to the window frame with an aluminium frame and magnetic tape.

In-frame roller blind

An in-frame roller blind is also a good choice when you want to keep heat outside. Because the roller blind is tightly integrated into an aluminium frame, it fits neatly against the window frame and leaves hardly any openings for heat to pass through.

Combined with blackout fabric, the roller blind forms an extra insulating layer in front of the window. This reduces direct sunlight and helps keep the room cooler on warm days. At the same time, you enjoy a sleek, neatly finished system that fits perfectly against the frame.

Which fabric offers the best heat protection?

In addition to the system itself, the choice of fabric also affects the heat-resistant performance of your window decoration. For the best insulating effect, blackout fabric (C fabric) or DUO fabric (D fabric) is often chosen.

Blackout C fabric blocks almost all light and therefore offers the highest level of heat protection. DUO fabric also has strong insulating properties but allows more daylight through. This makes it ideal for rooms where you want to reduce heat without losing natural light completely.

Which fabric is best depends on the room and your personal preferences. Are you looking for maximum heat protection and blackout? Then C fabric is often the best choice. Do you want to combine insulation with pleasant daylight? Then D fabric offers an excellent balance between comfort and natural light.

Can heat-resistant window decoration help save energy?

Yes. Because heat-resistant window decoration helps keep indoor temperatures lower, the need for fans or air conditioning may decrease. Insulating window decoration is not only useful in summer. During colder months, the extra insulating layer also helps retain warmth indoors for longer. This means that well-chosen window decoration contributes to a comfortable indoor climate all year round.

Choose the right window decoration for a cooler home

Would you like to protect your home better against summer heat? Then the right window decoration is a smart investment.

Framed pleated blinds in particular offer a strong combination of heat protection, insulation and living comfort. By choosing blackout C fabric or insulating DUO fabric, you get the most out of the heat-resistant properties of your window decoration.
