What is the opening?
It is the determining factor of the visibility and protection of UV rays of this type of fabric. Technically, the degree of opening is defined as the percentage of the total area of a fabric occupied by pore or hole.
The influence of the degree of opening with sun protection is related to the passage of light into a room allowing greater or less transparency in the tissue. The opening, the thickness and the color of the fabric influence the heat absorption and this is fundamental when it comes to the consumption of both air conditioners and heating, since the screen fabric favors the considerable saving of energy.
Here we present an orientation guide of how would be the different degrees of Opening in the Fabrics of the Rolling Blinds of Screen.

When no-drill Venetian blinds are the right choice
This type of Venetian blind works especially well on PVC or aluminium windows, as well as in rented properties, where a reversible installation that leaves no marks is a priority. Because they are fixed using non-invasive systems, they integrate neatly into the window frame without altering its structure, making them a logical alternative to traditional Venetian blinds when drilling is not desired.
From experience, they are particularly suitable for spaces such as kitchens, home offices or rooms with changing orientations, where the ability to tilt the slats provides a level of control that more static solutions cannot offer. They are also a practical option when avoiding any permanent intervention is important—something many customers appreciate over time.
In addition, installation without invasive tools brings a benefit that is often valued later on: the ability to remove or replace the blind easily. It’s common for customers who initially look for a temporary solution to keep it for years once the right system has been chosen.
What to consider before choosing them
This is where most questions arise. As with any no-drill solution, the final result depends on whether the system is compatible with the window and with how the space is actually used. Not all window frames have the same thickness, and not all rooms involve the same level of daily handling.
When configured correctly, no-drill Venetian blinds provide effective light control and a stable day-to-day solution. In other situations, it may be worth considering alternative options within the range—especially when greater thermal insulation, a different type of integration into the window, or a different response to direct sunlight is required. Being clear about this before making a decision helps avoid adjustments or changes later on.
In some cases, customers considering no-drill Venetian blinds also look at other non-invasive light-control solutions. For example, no-drill roller blinds can be a good option when a simpler operation or a continuous fabric is preferred; no-drill pleated blinds may work better if tighter integration into the window or improved thermal performance is a priority; and made-to-measure curtains are often chosen when a more decorative finish is the main goal. Understanding these alternatives doesn’t mean ruling out Venetian blinds—it simply allows for a more informed comparison and a better final choice based on real use.
