Ensuring a building’s roof is waterproof, on top of being structurally sound, is critical to the success of any building project. This course examines rapid curing, polymeric liquid-applied waterproofing membranes for roofing and other demanding applications. Discussions include the history of PMMA, PMMA system components and characteristics, the installation process, and the versatility of PMMA products.

One of the most complex and least understood areas where fire can propagate is at the perimeter of a multistory building. Fire can spread not only from floor to floor via the edge-of-slab/curtain wall intersections but also along the exterior building enclosure where untested, combustible components are often installed. This program outlines best design practices for providing fire protection for building occupants per ASTM E2307 and ASTM E2874.

Architectural metal fabric is a dynamic interior and exterior material used to create beautiful and functional façades, balustrades, and screening for a wide variety of commercial and public structures.

It also discusses how coatings and graphics technologies can be incorporated into metal fabrics to enhance branding and visual identity.

Creating a quieter, more comfortable building starts with a focus on windows and doors, the weakest links in the building envelope for sound transmission. This course covers the elements of sound, the metrics used to measure sound attenuation, and the glazing and installation options best suited for an effective sound control strategy.

Paving products comprise an important part of both the functionality and aesthetic of exterior spaces, including urban plazas, streetscapes, walkways, patios, and amenity spaces. This course provides an overview of architectural paving and segmental retaining walls (SRWs) as two primary applications of hardscaping products in these spaces. The course introduces architectural paving and its components, manufacturing, and products and then focuses on the benefits, construction, and available types of SRWs. Case study examples of both architectural paving and SRWs are provided to engage and inspire learners as to the applications, functionality, and aesthetic possibilities of hardscaping products.

Fluid-applied resinous coatings have the ability to meet the performance demands of spaces as varied as aircraft hangars, surgical suites, and high-end restaurants.
