What is the PortaScreen sash window screen made from?
The mesh of the screen is made from aluminium which means it is resilient, rust-free, fire-proof and doesn’t warp at high temperatures (it can withstand up to the heat of a match). Not only that, aluminium is a really light metal so the sash window screens are extremely light and easy to lift in and out of position. The frame is made from varnished wood and the corners are toughened to ensure the screen always keeps its shape.
