This time it is about knowing the intumescent ring/collar, a piece that allows compliance with the Technical Code in its Fire Safety chapter.
Thanks:
Fire Department of the Provincial Council of Zaragoza. They have devoted themselves to learning about the informative purposes that are the objective of these videos, and more so with regard to Fire Safety.
Mr. José Cifuentes Montoya "Maestro Cifu", with whom sharing a coffee in the morning is always a pleasure, a friend who shares the enthusiasm for dissemination. (If it doesn't help me, I won't even do the assembly myself).
Mr. Oscar del Pico, brother who helped me with DIY and who is an infinite source of inspiration.
Mrs. Ana Carranza, who has been left without going out to dinner for a hamburger with the Dyper potatoes that she likes, because I have spent the budget on the plasterboard and the profiles.
K-Flex, who gave us the test rings and thanks to that Ana has only gone one month without a hamburger instead of two or three months.
To you who see it, because without you... what is this for?
