When it comes to curtain walling, we liaise directly with the building contractor, who will hand the architectural plans over to us. We specify the requirements of every curtain walling system we do because we have to be 100% accurate with the calculations for the inertia values. As more architects are designing for larger sized glass, this becomes even more important – the bigger the glass, the higher the potential wind loads. We have to show proof of our calculations to be able to demonstrate the system will not be prone to twisting, buckling or any other potentially dangerous failure. We also have the right mechanical lifting equipment for any of our installations, another reason why we install what we supply.
