In PONSICO s.c.p. took since 1988 working with the manufacturer of aluminium profiles and accessories ALUGOM and its representative in Catalonia ALUNORD. Within the series offered by that provider, find one of the sliding-type market economic series. As we can see in the photos above the framework is extremely simple, such as the one used at the beginning of the aluminum back in the 70s. Both the frame and leaf are cut straight, and instead incorporate brackets screws in the corners, which greatly lowers the final price. As we can see in the photo sheet in the dyno this item approves an afterthought in all specifications. This means we will not have the same efficiency as more higher quality series, but in any case we will have performance problems, and a load of glass in accordance with their capabilities, we will have door or window for a long time. However we recommend higher series as A-70, since for a little more money, rentabilizaremos our door or window in a few years, due to the difference in energy efficiency between the two. Inquire without obligation price and applicable to this series finishes.
