Everything depends on the requirements of the space
When we want to choose a solar protection solution, the following question may arise: is better an interior roller blind or an exterior one? The short answer is that it depends. Neither is better than the other.
These systems are not only different because of where they are installed, but because they respond to different requirements. To understand this, we will analyse different cases and which aspects one or the other performs better.
Solar radiation, a decisive factor
One of the main reasons for choosing one option or the other is the level of solar radiation. When light passes through the glass, part of that energy remains inside in the form of heat. Once inside, that energy is more difficult to control.
In response to solar radiation, both blinds behave in different ways:
This is the biggest difference between both systems. The interior blind is a better solution if what we want is greater light control and improved visual comfort. On the other hand, the exterior blind is better if what we are looking for is to control the sun, not the light, and for it to act as a thermal barrier. If this is our main priority and what the space requires, it is the most recommended solution to choose.
Stability and resistance, what defines exterior systmes
When installing an exterior blind, we encounter different factors compared to interior ones. It must withstand demanding conditions such as wind, continuous exposure to the sun or temperature changes.
This is where we want to introduce one of the best exterior systems that Enrollatech can offer: ZIP guides.
ZIP guides
Systems with ZIP guides allow great fabric stability, thanks to the presence of side guides into which the fabric fits. This provides multiple advantager over other exterior systems, such as:
- Better wind resistance
- Permanently tensioned fabric
- No side gaps
ZIP guide systems are, ultimately, a more reliable solution when facing demanding weather conditions. In addition, since the fabric is fully guided, we achieve better light control and greater privacy.
Visual comfort and interior blinds
Exterior solutions have the advantage in thermal control, but interior blinds have a strong point in their favour: visual comfort.
They allow greater light control, making it possible to adjust the amount of incoming light. They also provide better visibility towards the outside.
For everyday use, interior blinds are a much more manageable and flexible solution.
In this article, we talk more about visual comfort and in which aspects a roller blind can improve it.
When to choose each solution
Combined solutions
There are projects where both solutions can be combined. This is not an unusual case and can lead to extremely functional solutions. We can use a ZIP guide system for thermal control and combine it with screen blinds, allowing us to control light more precisely when this takes priorioty over thermal control.
Combining solutions allows us greater control under all types of conditions.
There is no universal solution: each has its function
At Enrollatech, we will never talk about solutions that work for everything, because we know they do not exist. The choice will always depend on the space and its requirements.
When we understand in which situations each system is applicable, there is no room for error. The final decision must be made with technical criteria so that the system works as it should.
