Fakro DXW is a walkable, fixed (non-opening) skylight designed to safely support foot traffic. Designed to bring natural light into the space below through rooftop decks, green roofs, or other flat roof areas intended as walkable roof areas. The DXW skylight is equipped with DU6 reinforced glazing that supports up to 1,100 lbs of live load per 10 sq. ft. DU6 triple-pane glazing also provides excellent energy performance. The argon-filled double-chamber design and multi-chamber insulated PVC frame achieve a low U-factor of 0.22 (BTU/h·sq.ft·°F). Such a low energy transmittance keeps indoor temperatures stable year-round.DXW installation is straightforward: it sits directly on a roof surface and is waterproofed with a roofing membrane. It is suitable for flat roofs with a 0°-15° pitch and includes termination bars for roofing membrane installation.
