Window film installer FilmShield UK has applied some 2,400m<sup>2</sup> of high performance solar security film to the interior of the sealed units that make up the glass facade of the Northern Rock?s Solar House complex in Sunderland. The external surface of the glazed units incorporate thousands of solar energy absorbing tiles that act as individual solar panels, absorbing solar energy and converting it into electricity for the building. Internal conditions were uncomfortable due to a build-up of absorbed solar heat and high levels of visible glare. These problems were solved using the company?s high performance solar control window film.
