Compared to traditional steel and aluminum assemblies, this new generation of steel frames provides certain aesthetic benefits:<\/p>\n<ul>\n<li>narrower frames;<\/li>\n<li>sharp edges rather than rounded profiles;<\/li>\n<li>corner joints with no visible weld beads or fasteners; and<\/li>\n<li>flexibility to use back mullions of different shapes and sizes.<\/li>\n<\/ul>\n<p>Since manufacturers can now produce steel frames in long lengths and various complex shapes, design teams can select from hollow-, I-, T-, U-, and L-shaped mullions or custom profiles. Another option is to use the veneer connector to attach the curtain wall to glued-laminated (glulam) beams, I-beams, or round steel tubes, among other structural members.<\/p>\n<p>Advanced steel curtain wall systems use a \u2018steel veneer\u2019\u2014or glazing adaptor\u2014to overcome the challenge of fixed back mullions. This component can overlay onto nearly any modular back-mullion system, enabling it to receive glass or any other glazing material.<\/p>\n<p>To read the full article, click <a href=\"http:\/\/www.constructionspecifier.com\/masterformat\/an-advanced-frame-of-mind-next-generation-framing-for-energy-efficient-glazing\/\">here<\/a>.<\/p>\n<p>To read the other sidebar, click <a href=\"http:\/\/www.constructionspecifier.com\/masterformat\/an-advanced-frame-of-mind-the-window-to-wall-ratio-dilemma\/\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Using a roll-forming technique in which continuous steel coils are forced through dies and then laser-welded, manufacturers can produce steel window frame members in long lengths and various complex shapes. <\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[520,179,449,188,275,489,460],"tags":[616,613,614,617,618,615],"class_list":["post-2085","post","type-post","status-publish","format-standard","hentry","category-features","category-masterformat","category-uniformat","category-08-00-00-openings","category-08-40-00-entrances-storefronts-and-curtain-walls","category-b2010exterior-walls","category-b20exterior-vertical-enclosures","tag-aluminum-curtain-wall","tag-b2010-40fabricated-exterior-wall-assemblies","tag-curtain-wall","tag-energy","tag-high-performance","tag-steel-curtain-wall","entry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
