<p>An internal mobile screen device is disclosed for providing variable insulation, lighting, decoration, solar energy collection or solar radiation reflection. The device comprises mobile insulating strips inside transparent plastic cellular plates and is designed to solve problems of overheating below roofs generally in summer and to insulate said roofs in winter, while still allowing light to pass through said strips. An area of black strips is provided for solar energy collection. The device consists of a transparent plastic box in the form of double or triple wall cellular plates (2) in which the white or black insulating strips (1) can be moved by means of pulleys (4) and micromotors (5) to position the strip according to its purpose. A casing (7) collects hot air which is directed into a storage unit or used directly to heat another room. The device is intended particularly for use in all types of roofs or edging elements or verandas, private houses, agricultural and industrial buildings, and greenhouses.</p> |
