Curtain walls by Palladio SpA – Economic solutions for sophisticated glass and steel architecture
Technical research into curtain walls is constantly developing. Pursuing maximum transparency and lightness in a curtain wall project does not mean renouncing safety and high heat and sound insulation performance, rather, when the architect chooses steel, by nature strong and flexible, these features are guaranteed and can be used as the basis of the project and totally relied upon.
In terms of strength, steel plays a very important role as a material more than most others able to adapt to needs of low maintenance, easy installation and simplicity of use, all essential factors in the construction site to respect the budget and ensure speedy operations. The tubular steel profiles used for the Palladio Spa curtain walls, the considerable thickness of the steel plate used to make the profiles, mean the final product is extremely strong while the supporting section size is reduced to a minimum, while the correct combination between profiles and seals is essential to guarantee the correct water, air and wind tightness. When joining the steel profiles and seals using silicone mixtures, the first rule is to ensure the seal is memory retaining even after repeated cycles of shrinkage and expansion and anti-age tests, which prove the unaltered properties of the structure throughout its life cycle. The system of seals acts as a spacer between metal profile and glass, allowing the different materials to dilate separately, but with the same loads and hygrothermal factors in the site. The series of profiles offered by Palladio Spa gives a wide choice ranging from the use of T-section profiles, to tubular profiles with dovetail grooves, which have the dual advantage of strengthening the supporting section and providing easy anchorage along the length of the profile, with no further work required. There are then the commercial profiles with a screw-in slot for fixing the seals and glass. The aim is to be economic, fast and easy to assemble on site, low maintenance, and total guarantee of unaltered characteristics of the curtain wall over the years.
