Storefront Windows, Window Wall, Curtain Wall – What's the difference
Most architects believe they understand the differences among glazed opening framing systems. Published construction drawings and specifications indicate many individuals do not understand differences well enough to label openings correctly to coordinate with project specifications. Manufacturers know the differences because their literature segregates the various framing systems. MasterFormat®, the industry standard for specifications numbers and titles, includes specifications section titles for each system. MasterSpec, SpecText, and Speclink, the commercially available master specification systems, follow MasterFormat® and include separate specifications for each system. The reason: the systems are distinctly different - different performance, different applications, and different costs. Understanding the difference will help ensure drawing notations are coordinated with the specifications.
