These pre-assembled units (typically one storey in height and one bay in width) are then transported to the construction site and lifted into position by crane.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Think of a unitized curtain wall as <strong>pre-fabricated building blocks<\/strong> for the facade.

transom profiles are cut, machined, and finished<\/li>\n\n\n\n<li>Frames are assembled into large sections (typically 2\u20133 modules wide)<\/li>\n\n\n\n<li>Thermal breaks, drainage systems, and gasket grooves are integrated<\/li>\n\n\n\n<li>Glazing may be partially or fully completed in the factory<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Transportation<\/h3>\n\n\n\n<ul
