Coimbatore mornings and evenings bring mosquitoes — particularly during and after the monsoon. uPVC windows with integrated mosquito mesh let you keep the windows open for airflow without letting the mosquitoes in. The mesh isn't an afterthought bolted onto the outside — it's built into the window frame from manufacture, with its own track parallel to the glass sashes. Glassterr manufactures uPVC windows with integrated mosquito mesh at our Pannimadai factory using SS304 stainless steel mesh (rust-resistant, fine enough for mosquitoes while still letting air flow). The mesh slides independently of the glass sashes, so you can have any combination of glass open/closed and mesh in/out of the way.
Mosquito mesh for uPVC windows uses a fine stainless steel mesh (SS304 grade for rust resistance) stretched over a uPVC frame that slides on its own track parallel to the glass sashes. The mesh frame is the same width as the window opening and slides horizontally to either side, so when you want the mesh in place you slide it across to cover the opening; when you don't, you slide it to one side and tuck it against the frame. The mesh aperture is fine enough to stop mosquitoes (typically 1.5mm × 1.5mm) but still lets air and reasonable light through. Mesh integration adds 1 track to the window frame design, so the overall section is slightly deeper than a non-mesh window.
It reduces airflow somewhat — typically 20-30% less than no mesh — but the trade-off is overwhelmingly worth it during mosquito season. For bedrooms especially, the airflow reduction is much less important than the mosquito blockage.
Stainless steel lasts 20+ years; fibreglass and plastic mesh start degrading from UV and humidity within 3-5 years. The price difference at purchase is small but the longevity gap is huge. We use SS304 stainless as standard. If you specifically want fibreglass mesh for some reason (lower cost), we can do it but don't recommend it for Coimbatore conditions.
Yes — casement mesh is fixed to the inside of the frame on removable clips (since the sash opens outward). You can pop the mesh off when you need to clean the window. Mesh on casement is slightly less convenient than on sliding (because it's not on a track) but works fine.
From inside, the mesh is barely visible when properly tensioned — it looks like a very fine grey screen across the opening. From outside, it's slightly more visible but still subtle. Modern mesh is finer and less visually intrusive than the old wire-screen looks people remember from older homes.
Typically ₹2,000-4,000 per window for sliding window integrated mesh, slightly less for casement. For a whole 3BHK home with mesh on 12-15 windows, expect ₹30,000-50,000 added to the total order. For mosquito-prone properties, it's almost always worth it.
