The double glazed glass panel is made up of: 6mm toughened outer, a 90% argon filled cavity, with a laminated inner (inc. 1.5mm PVB interlayer). The inner pane thickness varies with rooflight size, see table on page 3. All double glazed units include a soft coat Low E coating.
The frame is extruded aluminium, with a powder coating (RAL 7016) to provide a premium appearance and highly appealing finish, and is thermally isolated to provide excellent thermal performance. The kerbs are manufactured from Lead & Cadmium free un-plasticised PVC rigid multi-wall extruded profile, with internal white finish. The Glass, PVC-U and Aluminium which comprise the product can be recycled at the end of useful product life.
Brett Martin Flat Glass achieves a Ud-value (defined in accordance with NARM NTD02) of 1.16 to 1.66 W/m2K and a centre pane U-Value of 1.1 W/m2K which exceeds requirements of Approved Document L of the Building Regulations.
Brett Martin Flat Glass units achieve a direct airborne sound insulation value of 38db (Rw). This value can be improved further by the fitting of a kerb acoustic pack. The acoustic pack is not available with vented or opening options.
Brett Martin Flat Glass units are suitable for flat roof applications with a pitch of 2O-15O. 2O is typical for a ‘flat roof’. If a roof is less than 2O, packers (not supplied) will need to be placed under the kerb of the unit or on the top of a builders upstand to raise to the minimum 2O. This is to prevent water ponding on the glass leading to rapid dirt build up. A minimum of 4O pitch is required for sizes where both the length and width are larger than 1650mm.
