The front elevation of my house has a two "12 feet(height) x 3 feet(width)" windows where i was planning to make use of glass to close it. But i am having two minds here as whether to use complete glass or steel vertical rods or wpc ....Can you help me decide which material is much better (in terms of durability , climate independent, low maintenance and which looks good for the elevation) . You can also suggest any other material u know about .. Th photo uploaded will show a similar elevation where u can see the stairs visible ...i want to close it to prevent rain water from falling in
