Introducing SteelBuilt Curtainwall™ Systems

Envision expansive window openings, with more glass and less frame. Imagine a curtainwall system that only requires frame profiles one-third the size of traditional aluminum systems.

Now that dream is a reality, with the new SteelBuilt Curtainwall™ Systems from Technical Glass Products (TGP). SteelBuilt Curtainwall Systems give you all the advantages of steel: greater strength, superior performance and improved aesthetics. Utilized throughout Europe for many years, SteelBuilt Curtainwall Systems have been tested to North American standards and are now available to open tremendous new design opportunities.

NARROW FRAME WIDTH	1–¾" (45 mm) face width vs. typical 2–½" face width of aluminum (SteelBuilt Curtainwall also available in 2–3/8” (60 mm width).
NARROW FRAME DEPTH	Narrow 5–¾" back mullion using the SteelBuilt Curtainwall system vs. a required depth of nearly 8 inches for a typical aluminum curtainwall system. (SteelBuilt Curtainwall Systems are available with internal reinforcements to further reduce required frame depths).
LARGE SPANS	20 foot span with no additional reinforcements required.
LARGE GLASS SIZES	Considerably larger glass sizes possible when comparing the same size frame profiles.
DURABILITY	Strength of steel profiles ensure long-term resistance to denting, scratching or deterioration. SteelBuilt Curtainwall systems can also include stainless steel cover caps for aesthetics or increased durability.
