FILT3RS is a platform that disseminates knowledge about a broad understanding of types of openings and filtering devices that connect our buildings from the interior to the exterior. It wants to promote the design of windows, balconies, covered balconies and its filtering elements, such as shutters, blinds and lattices, in order to achieve the variety of possibilities required by our climates and our habits to control the relationship between the interior and the exterior.

NEWS AND TRENDS

Filt3rs turns three years old and its aim has been gradually defined. Its success is highly remarkable (from 4 to 8000 visits per month, with over twenty thousand visited pages). This diffusion encourages promoting the platform as a way to make public my concerns about the control of interior/exterior relations in architecture. In these lines I will develop these issues, linking some contributions in our gallery.

Micro perforated sheets and slats

Today I want to draw your attention on micro perforated sheets and slats. It is a solution that tries to combine solar protection and outward views. It might not seem a good solution, since while more perforation improves the view of the exterior; it also reduces the solar protection. However, the brain can reconstruct the image with little information, if it is widely distributed. For this reason, sheets with about ten percent of drillings give sufficient visibility to the outside, almost completely preventing the entrance of direct sunrays.

When the perforations are very small, about a couple of millimetres, the thickness of the sheet starts to matter. It is because this thickness blocks the sunrays for certain angles of incidence. Solar protection can be really efficient, as in these examples [567557445504474375257251058].

In the following cases [542528530325] it can be seen that the perforation is excessive, with little improvement of vision range and less efficiency of solar protection.

A unique wrapping   

Lattice filters allow covering all the building with a single material, satisfying the schematic minimalism. This builds elementary boxes with a surprisingly universal attractive. Boxes wrapped in meshes, perforated plates or all kinds of lattices are spread around all latitudes, hiding the diversity of materials that lie behind them. [547 - 548 - 491 - 151 - 200 - 135]
