Sun Screen UV Opening Factors

We will clarify in this article what influences and what the opening factor means and depending on what you should choose the opening factor of your sunscreen blinds fabric.

How to decide the opening factor of your blinds?
Screen fabrics are manufactured with different opening factors. 1, 3, 5 and 10% also exist in higher factors that are very little used and not very functional.

Screen fabrics are fabrics made for use in sun protection (UV) when this fabric is made it is made with thousands of interwoven threads to form a uniform fabric, the separation between the threads determines what degree of light will pass, that is from 1 to 10%.

In addition to the solar control, the percentage of opening of the fabric is also the one that will define how much is seen from the outside towards the room, from zero visibility with 1%, silhouettes 2 meters away with factors 3 and 5% and a little visibility from outside the inside with the 10% factor.

In all cases, outward visibility is preserved, more or less clearly depending on the opening factor. (The opaque image represents the Black Out fabric)

Opening Factor

Choice of rooms.
For Bedrooms:
InUNITEC we believe that the ideal for the bedrooms is to install Double Roller, that is, Sun Screen UV + Black Out, however, the budget is not always enough to finance this since the value of the curtain is almost doubled, or simply not we like that the rooms are completely dark, the best alternative to keep the budget under control and have the privacy that a bedroom need is to choose a low opening factor of 1%, maximum 3% if only a Sun Screen UV curtain will be installed, if the Choice is Double Roller the recommendation will definitely be Sun Screen UV 5% + Black Out.

For: Living / Dining / Living Room / Study / Kitchen
The choice here is very simple, factor 3 or 5% is perfect for these rooms, they eliminate visibility from the outside 2 meters away, the amount of light that enters is appropriate to keep the environment naturally illuminated.

Selecting a 1% opening factor for these rooms does not make much sense, it eliminates a lot of light entry and forces the lighting to turn on very early. (take into account energy savings).

We don’t mention 10% in our analysis, this opening factor looks really beautiful! the blinds are very beautiful and the transparency is perfect, however, very few places lend themselves to this choice, the windows will have to be internal, interior gardens, swimming pools, offices on high floors. This factor allows that from the outside it is seen in detail inwards more than two meters away, they are beautiful but not very functional for our taste.

Consider in your analysis the economic factor, we will leave this information for you to learn more about the blinds you are thinking of buying.

The values of your sunscreen blind fabric according to the opening factor range from the cheapest to the most expensive in the following order.

5% – 3% – 1% and 10%. yes, 10%! The latter despite being the biggest opening factor is the most expensive of the entire line.
