Know your WiWA© score

Eternia’s aluminium windows and doors have a high degree of customisation available.

• You can customise your windows and doors with the colour and finish of your choice.
• You can customise your windows with high-performance glass if you’d like, to keep out loud noise.
• You can get a window customised to a WiWA© score that is the best fit for your home. WiWA© certifications verify that windows have been tested to meet international parameters for air permeability (a measure of how well sealing keeps out elements like heat, dust and noise), water pressure (how well your windows can keep out heavy rains) and wind pressure (how well windows can withstand heavy wind loads, including cyclones).
