Sliding Mosquito Nets for Corlim.

Corlim needs a net that can be cleaned as well as one that keeps insects out. Mesh acts as a filter, and with the industrial estate nearby it clogs with dust; a sliding-frame net lifts out of its track and can be washed under a tap, which a fixed mesh cannot. That makes sliding frames the better choice for flats and row houses here, on bedroom windows and the balcony door. The low ground towards the river is humid and breeds mosquitoes through the rains, so homes on that side should screen every opening used after dark. This far from the sea, aluminium frames with fibreglass mesh hold up well.

• Flats in apartment buildings: sliding nets on bedroom windows and the door to the balcony, taken out and rinsed when dusty.
• Row houses near the river side: nets on the kitchen and bathroom ventilators too, because one open gap lets the mosquitoes in.
• Staff housing with swing doors: a pleated net on the main door, folding flat to the side when people come and go.
