Window Wall

Products and Applications


Storefront and Entrances Window wall is defined in NAFS as, “A non-load-bearing fenestration system provided in combination assemblies and composite units, including transparent vision panels and/or opaque glass or metal panels, which span from the top of a floor slab to the underside of the next higher floor slab. NOTE: Window walls are available with separate or integral slab edge covers and can be fabricated from windows or curtain wall or storefront systems. Primary provision for anchorage occurs at head and sill conditions. Receptor systems can be designed as a part of drainage and movement accommodation provisions.”

Window wall “rests” on the floor below, and expands in the same direction as interior finishes, for easy interfaces at door openings and balcony slabs. Shear walls and changes in sill height are straightforward. Window wall can be installed in any sequence.

Window wall can be designed to look as much - or as little - like curtainwall as desired. Performance criteria are similar. Window wall made from window systems - like Wausau’s INvent™ product family - looks more “residential,” with expressed interior glazing beads, and framing sightlines interrupted by offsets. Optional beveled or profiled glazing rebates are available, while vents are integrated into framing. Structural silicone glazing is generally unavailable.

Window wall made from unitized curtainwall - like Wausau’s INvision™ product family - looks more “commercial,” with rectilinear mullion proles interior and exterior, and glazed-in insert vents. “Chicken head” starters are used at slab conditions. SSG is optional.
