95WW Series Window Wall

Hybrid unitized window wall system (hybrid between window wall and unitized curtain wall) combining the components of the 5000 and 85WW Series.

This system allows for installation from the inside of buildings with anchors embedded in the concrete that allow for deflection of the slabs, such as the 5000 Series, in addition to allowing for the replacement of glass from the inside in case of breakage.

Unitized architectural product made from extruded aluminium of 6063-T6/T54 minimum alloy with polyamide thermal break. Assembled by rolling and crimping with a shear test of minimum 400 kg. Typically used for the continuous facade area on large buildings.

This product is designed as per rain screen principle, with a pressure equalization chamber to prevent water infiltration.

  • Window wall allowing the installation of double or triple sealed units
  • Insulated Glass Unit (IGU) options: 25mm (1”), 32mm (1 ¼”) and 38mm (1 ½”).
  • Specification of the glass or a spandrel panel at the professional’s choice

All sealed units are installed from the inside with a mechanical snap-in air barrier and water barrier moulding.

Spandrel glass or aluminum panel combined with 20-gauge galvanized steel insulated back pan with interior fire stop and smoke seal (at slab edges only).

All LESSARD® leaves can be integrated into this product without sub-assembly.

Each unitized frame is connected to the others without a sealant. All air and water tightness assured by a dry EPDM or silicone gasket.
