In the market we have many types of sun protections to use on windows; fabric curtains, awnings, blinds… etc. But as we will see throughout the article, the Blinds that we use in the carpentry of our houses, possibly one of the best solutions we can adopt.
As anecdotal data and a bit of history of this type of lattice, they have their origin in the 18th century, in Persia, where a piece of cloth was used to cover doors and windows blocking the passage of light and dust. Its name derives from the French word persienne, which means, from Persia.
