There are five main pane types: (--59) Toughened outer pane (--34) Obscure glazing, toughened outer pane (- -73) Toughened outer pane with clear and clean coating and laminated inner pane for additional safety (--60) Improved U-value and greater noise reduction. Toughened outer pane with clear and clean coating and laminated inner pane for additional safety (--65) Triple glazing, lowest U-value and noise reduction. Laminated inner pane with clear and clean coating on toughened outer pane Further details on these and other panes are provided in Section In addition, to suit the specific requirements of any particular project, there is a wide range of alternative pane variants. Dual sealed insulating unit Dual sealed insulating glass unit. 2. Spacer of stainless steel. 3. Desiccant, ensuring that there is no internal condensation in the cavity between the glass layers. 4.

5 Glazing options For optimum performance VELUX recommend use of --73 or --60 glazing variants. (--59) (--34) Standard --59 Pane This standard glazing comes with a toughened outer pane. In winter, it reflects 60% of the heat normally lost through glass, back into the room. During the summer, it works in reverse by reflecting excessive heat from the sun to help prevent the room from overheating Obscure Panes Combines standard glazing with the inner pane obscured. This makes it ideal for bathrooms as it provides privacy without reducing the amount of natural light. (--73) (--60) --73 Pane An improved version of our Standard --59 Pane, this glazing comes with a toughened outer and laminated inner pane. This makes it ideal for windows that are positioned above head height. As well as giving you extra protection against breakage, it has improved noise reduction, compared with --59 Pane. It also comes with our clear and clean outer coating, which helps the window stay cleaner for longer. Ideal for highlevel applications, which are hard to access Pane As with the --73 Pane, it comes with a laminated inner for extra protection. The added benefit of the --60 Pane is that it offers even better energy efficiency and noise reduction. It also comes with our clear and clean outer coating, which helps the window stay cleaner for longer. Ideal for high-level applications, which are hard to access. (--65) --65 Pane Triple glazed giving the lowest U-value and greater noise reduction. As with the --60 pane, it comes with a laminated inner for extra protection. The --65 pane also comes with our clear and clean outer coating, which helps the window stay cleaner for longer. Ideal for high-level applications, which are hard to access. We also have additional glazing options, which are available for special requests. Section VELUX Group Products q Insulating glazing units
