D_F WINDOW - COLOURLINE VERSION

The type F is equipped with an energy-efficient, triple DU6 glazing unit. The external glass 6mm thick is toughened while the internal glass is laminated and anti-burglary P2A class. Should the pane crack, shards of glass do not pose a danger but remain on the laminate film. Heat transmittance co-efficient for the whole window is U=0.88 W/m2K (to EN 12567-2). The window is also available to order with a quadruple U8 glazing unit. Heat transmittance co-efficient for the whole D_F DU8 window is U=0.76 W/m2K (to EN 12567-2). Such excellent parameters make the window suitable for use in energy-efficient and passive buildings.
