| Since
1988, Masa has been providing the definitive technological solution for
front daddings, obtaining the best quality and effectiveness |
|||||||||||||||||||||||||||||
| Each
of the elements which make up the masa system has been conceived to achieve
the maximum quality and efficiency, both technically and economically, so
that our products today fully satisfy a series of strict specifications
which masa has established as priorities since our firm first began operating
in the market:
Adjustment
of the level of the fixing in its three dimensions (x, y and z-axes),
without forcing the cladding panels. The
fixings designed by masa constitute an intermediate system between the
structure of the building and its facing, effectively facilitating ventilation
by means of an air chamber created between these two elements. Also, masa
fixings ensure a continuous insulation, which reduces the number of thermal
bridges while optimising the thermal inertia of the building. At the end of 19th Century-beginnings of 20th Century, a big technological advance took place in construction, when structural and outdoor skin functions were regarded separately for the first time. This change affected façades with stone skins. Amble walls made of a unique material (masonry fronts) were left behind because of the appearance of mechanised sheet skins of a few centimetres of thickness. From the aesthetic point of view, the new type of façades try to look like stone fronts that had been substituted and it was in that moment when a new need arose: the use of angle sections to achieve a better closing mechanism at the skin walls next to holding mortar. At that moment, angle sections were simple, as their main function was to prevent the sheets from knocking over. The most commonly used materials were constituted wire, carbon steel, galvanised steel... During the 70-80’s, all the pathologies of this kind of façades (such as damp, efflorescence, and the worst, sheet’s taking down) made the specialists think about the liberation of façades for the first time. Strong weather conditions, thermal changes with severe alteration of materials, stiff or retractable mortars with little adhesive conditions or even angle section that did not resist corrosion were other good reasons to explain the advance. Though new fronts were still dependant on the building’s structure and sometimes on the skin walls too, they had their own movement, thanks to its materials dilatations. On the same way, subjecting and joining systems gave a step forward too when both of them substituted mortars and started carrying out the functions of supporting elements. From that day on, they were made of corrosion proof materials for being exposed to all kind of weather conditions. Nowadays, fixing elements are a really consolidated constructive option due to two reasons: their independence from deformations and the great constructive tolerance between the structure/skin and the panelling. The
evolution of the fixing elements has always influenced any technical manipulation
of the stone, as the joint with the angle section must always be solid
and secure. The problems of traditional fronts have been solved by the establishment of this new generation of fronts. Regarding this subject, our firm’s contribution should always be taken. |
