Facade Design — Elizabeth Bishop

Stick systems come to site as a kit of parts, the mullions and transoms being the ‘sticks’. Stick systems can be less expensive than unitized or window wall systems but can also require more on-site labor. They are often used at ground floor entrance areas. The plan above shows a section through a stick system through two areas of vision glazing. The vertical section above cuts through the base of a stick system. Brackets connecting the system to the slab are shown with dashed lines. This sketch of a vertical section through a timber rainscreen shows the basic elements of the system: backing structure supporting brackets; brackets affixed to battens; battens fixed to timber boards. Proper ventilation and waterproofing are critically important, as is specifying the correct type of timber. ETFE pillows are a lightweight solution often used instead of glazing for roof lights or sometimes entire roof systems. Layers of ETFE can be used to achieve different performance requirements.
