Profile: W P L (UK) Ltd. specialize in the design, manufacture and installation of louvres, brise soleil and architectural mesh facade systems. Our external range of solar blade profiles provide the architect and specifier with the option to use either flat blade profiles or hollow section profiles generally referred to within the industry as aerofoil sections. The aerofoil blade sections offer a massive choice of profiles from elipses to diamond geometric shapes. Our extruded aluminium louvre systems are designed to span mullion centres of 1000 and 2000mm depending on site location. Blades are snapped into position by locating the rear louvre upstanding into the mullion clip socket. The front blade is snapped into position by an integral forced spring locking action between the node and the clip cantilever lug.
