What are day and night roller shutters and how do they work?
Day and night roller shutters consist of two layers of fabric that overlap and alternate in stripes - transparent and blackout. By moving the fabric relative to each other, you can easily adjust how much light should penetrate the room. When dark stripes overlap with transparent ones, daylight flows into the interior. When stripes of the same type overlap, you achieve partial or almost complete blackout. The big advantage is that the roller shutter does not have to be pulled out as a whole – you can regulate the light by simply moving the fabric.
This type of shading is very versatile: it is suitable for the living room, bedroom, kitchen and study. This way you will not only get the necessary privacy, but also the opportunity to adjust the atmosphere of the room according to the time of day.
The main advantages of day and roller shutters
The main advantages of these roller shutters include:
- Possibility of smooth regulation of the light in the room,
- maintaining privacy even during the day,
- modern appearance and clean lines,
- easy maintenance,
- possibility of installation without drilling (depending on the type of blind),
- they are suitable for both classic and plastic windows.
What to consider when choosing day and night roller shutters
The right choice of day and night roller shutters depends on several key factors. Be sure to pay attention to them.
1. Type of installation
As a first point, consider where and how you want to place your roller shutter:
- directly on the window frame (ideal if you want to keep the window sill free),
- in a niche (a clean solution for fitting the roller shutter into the space),
- on the wall or ceiling (suitable for French windows or larger areas, let’s say).
Our VERRA SEMI day and night roller shutter model allows for installation both in a niche and on the window sash. The advantage is the option with a cover, which elegantly hides the fabric roll, and the option with brackets for installation without drilling - ideal for rental apartments or for those who want a minimalist solution without interfering with the frame.
Today, the last-mentioned method is increasingly popular, where you attach the roller shutter to the window frame without drilling.
2. Control
The standard option is manual control using a chain. In most cases, you can choose whether the control chain for this roller shutter is on the left or right, which guarantees comfortable use regardless of the location of the window. For more demanding clients, a solution may be to control the roller shutter with a motor. Well, that is also available on the market. Then you can even control the roller shutters using your smartphone.
3. Colour and type of fabric
The colour and structure of the fabric affects not only the appearance of the roller shutter, but its functionality as well. In our offer you will find a wide range of decors - from neutral white, through natural shades to bold colours and patterns. It’s up to everyone what they opt for. When choosing, consider whether the fabric should rather match the interior or dominate.
Remember that fabrics for day and night roller shutters also differ in degree of light transmission. For the bedroom, select a fabric with a higher level of blackout, for the kitchen or living room, a more transparent option.
The right colour shade is therefore important for two reasons. First, it completes the overall aesthetic impression of the interior and also affects the amount of light that the blind lets into the room. So do not underestimate the choice of the roller shutter.
Lighter roller shutter colours are a better choice for smaller rooms, which dark roller shutters could make them appear even smaller and create a feeling of crampedness.
Also pay close attention to weight of the fabric. It is the weight in grams of the fabric, as well as its colour, that has a significant impact on how dark the room is. As a general rule, the higher weight of fabric, the less sunlight it lets in.
4. Dimensions and custom-made manufacture
A quality roller shutter should match the dimensions of your window. It is therefore ideal to buy a day and night roller shutter that is accurately made to measure, which of course allows for perfect coordination with each type of window - without overlaps, gaps or aesthetic compromises.
5. Maintenance and durability
Our day and night roller shutters are made of antistatic materials that repel dust and dirt. For routine maintenance, wiping with a damp cloth is sufficient; no special cleaning is required. The fabrics keep their colour and shape for a long time with no deformation.
When choosing, look for quality fabrics. In addition to poor workmanship, cheaper roller shutters pose a risk of lower quality materials. They can wear out a lot in a few years and then they do not look good. And none of us want a shabby-looking roller shutter at home.
