SEMI UNTIZED SYSYTEM
Semi-unitized systems combine some of the advantageous features of both
stick and unitized curtain
wall systems. Unlike stick systems, where glass delivered to the construction site on its own, each
piece of glass is pre-bonded into
a smaller metal cassette that is eventually locked into a larger frame on site.
As a result, on-site assembly includes connecting metal-to-metal frame components, mediated with
gaskets, which is fast and safe.
It also precludes the need for site-applied structural silicone. “Nobody really likes working with
structural silicone on site; it does
happen, but when you can avoid it, you should,” Simmons said. “Structural silicone is always best
done in climate-controlled factory
conditions by experienced technicians.”
