Frequently asked questions

All of Eternia’s aluminium sliding windows for balcony spaces can effectively keep out water leakages, as they are WiWA© certified for water pressure- a measure of how well the window can keep out heavy rains. Our aluminium sliding windows for balcony spaces can also withstand heavy cyclones (tested for wind pressure) as well as keep out noise, dust and heat (tested for air permeability).
