GUIDE
Curtains in large window sections
Large windows provide wonderful light and spaciousness – but can also present challenges with heat, glare, and privacy. A good curtain solution can therefore be particularly important during the sunny and warm months of the year when the sun is strong. In glazed conservatories or rooms with panoramic windows, the temperature can quickly rise, and strong sunlight can also affect the interior. In addition to sun protection, many also want to be able to screen off for privacy when needed – something that often becomes extra important in rooms with large glass surfaces.
There are several practical options that work well for large windows, such as vertical blinds, roller blinds, and curtain panels. In this guide, we review good choices for curtain solutions for large windows and help you find the right one based on your needs and conditions.
How to choose the right curtain solution for large windows
Large windows place different demands depending on both the design of the window and the feeling you want to create in the room. The best solution for your windows depends on several factors, but there are some general guidelines that can be good to keep in mind when choosing curtains for large windows:
- Do you want to reduce heat and glare? Choose vertical blinds or roller blinds that effectively block out the sun.
- Do you want a soft feel and to frame the window? Choose curtain panels for a cozy and stylish expression.
- Do you want to be able to black out? Choose a sun protection or curtain in blackout fabric – preferably as a combination solution if you want to be able to vary the light input.
- Do you have tall windows? Choose a solution that is easy to operate, such as vertical blinds or a motorized curtain solution.
- Do you want to maintain the light input? Opt for thinner curtains that softly shade, or roller blinds in screen/light-filtering fabric.
- Do you have angled windows, so-called raked windows? Choose vertical blinds.
Below, we will go through vertical blinds, roller blinds, and curtain panels in more detail, so that you can more easily find the solution that suits your large windows.

Vertical blind
Vertical blinds are a sun protection specifically designed for large window sections. They are excellent for panoramic windows and are also a popular choice in conservatories where the walls largely consist of glass and you want to reduce heat gain and adjust privacy as needed.
With vertical textile slats that can be angled, you can easily vary the light, and when you want to open up completely, you can slide the slats to the side so that the window is clear. Vertical blinds are available with both screening fabric that allows light through and with blackout options for easy light regulation.
If you want to read more about measurements, installation, and fabric selection, you can find it in our in-depth guide on vertical blinds.

Curtains
Curtains are an excellent choice for large window sections, especially when you want to create a soft and cozy feel that frames the window.
Our curtains can be custom-made up to 7 meters in height, making it possible to use curtains even for very tall windows. Curtains on curtain tracks are also a good choice for wide window sections, as they can be built and adapted to any width to create a seamless curtain solution over large areas. You can also hang several panels next to each other to achieve an even and uniform look across a wide window section.
Choose curtains based on function: sheer curtains are a good choice when you want to maintain light entry while also providing soft privacy. In bedrooms or rooms where you want to block out light, blackout curtains are more suitable. For a flexible solution and an extra hotel feel, you can also combine double curtains.

Large roller blinds
Roller blinds are a stylish and practical sun protection solution that are particularly well-suited for large window sections, as several models can be made extra wide and tall. With different roller blind fabrics, you can easily adapt the solution to your needs – whether you want more privacy, to reduce glare and heat, regulate light, or be able to blackout the room.
The fabrics are divided into three main groups based on their function:
Screening fabric: lets in daylight but reduces direct sunlight.
Screen: a transparent fabric that reduces sunlight and heat gain.
Blackout: blocks out light and darkens the room, for example in bedrooms.
Roller blinds can also be advantageously combined with curtains in large windows, for a flexible overall solution that is both practical and attractive.
Common questions about large window sections
Vertical blinds or roller blinds - which one should I choose?
When choosing between vertical blinds or roller blinds, it mainly depends on the window's dimensions and which function is most important to you. For extra large windows, vertical blinds may be a better choice as they can be custom-made in larger sizes than many roller blinds. If, on the other hand, you want more freedom of choice in fabric – for example, screen fabric that can reduce heat and glare without blocking the view – roller blinds are often a good option.
Which curtains are best suited for large window sections?
Which curtains are best suited for large windows depends on how much light and privacy you want to control. Most of our curtains can be custom-made up to 7 meters in height. Choose sheer, thinner fabrics if you want to maintain light while still getting soft privacy, or thicker fabrics if you want to block out more. For wide window sections, curtains on tracks are a good choice, as you can adjust the width and hang several panels next to each other for a uniform and seamless look.
How do I reduce heat gain from my large windows?
To reduce heat gain from large windows, a roller blind with screen fabric is an effective choice. The screen fabric helps to block the sun and reduce heat, while maintaining both the view and natural light.
Which solution is best for a glazed outdoor room?
In a sunroom with large glass sections, vertical blinds are often one of the best choices. They are suitable for wide areas and make it easy to vary between fully screened, partially open, or fully open positions – so you can control light, privacy, and heat as needed.
Which sun protection is best for slanted windows?
For sloped windows, vertical blinds are often a good choice, as they can be adapted to the window's angle and provide flexible shading even when the window is not straight. Feel free to contact us and we will help you find a complete solution that suits your measurements and conditions.
What's the best way to black out large windows?
To best darken large window sections, you need to choose blackout fabric or material. Keep in mind that different solutions may let in varying amounts of light from the sides depending on design and installation. For more effective darkening, you can combine several options, such as blackout roller blinds together with blackout curtains.
How do I get privacy without blocking out light?
To gain privacy without blocking out light, you can choose sheer curtains or sun protection with screening fabric or screen fabric, which let in daylight while still providing privacy. Remember that privacy is often perceived as a greater issue in the evening when you have the lights on indoors and it's dark outside. For more privacy, even in the evening, you may need to complement with a denser fabric or material – or a blackout solution if you also want to block out the light.
What should I consider when I have high windows?
For tall windows, it is most important to choose a solution that is easy to operate, especially if you want to be able to switch between open and closed modes frequently. A motorized solution controlled by remote control or app is a convenient option, and vertical blinds can also be practical when you want to easily regulate the light. For curtains, a corded track system is a good choice, as you can open and close without pulling the fabric itself.
Can I order extra-wide curtains for my large windows?
You can order curtains with a maximum width of 268 cm per length. For wide window sections, you can instead hang several lengths side by side, preferably on a curtain track, to create an even and seamless curtain solution across the entire surface.
How do I measure for a solution for my large windows?
How you measure for large windows depends on the solution you choose, such as vertical blinds, roller blinds, or curtains. To get the correct measurements, we recommend that you follow our measuring guides for each product, which provide step-by-step instructions tailored to the specific blind solution you are ordering.
