ColourLine, an option with FAKRO DEF flat roof windows, enables outer cladding to be specified in any RAL colour from the Classic Palette, says the manufacturer.
Whether used to blend with a green roof, terrace landscaping or tiles on pitches up to 15°, thermally efficient glazing units provide an installed U-value as low as 0.76 W/m² — ideal for Passivhaus construction. White PVC interiors are suitable for bathrooms and wetrooms, while windows from 60×60 to 120x220cm are said to have a glazing area up to 16% greater than many windows of comparable size on the market. All can be installed with an XRD upstand to add 15 cm height.
