This topic includes information related to design and construction of entrances. Entrances are opening where access to the interior is allowed to a structure or space from the exterior. Entrances may be manufactured glass panel, wood or metal and have operable mechanics such as automatic, revolving or pivoting. Certain applications may require pressure resistant or specific door characteristics.

This topic includes information related to folding doors and grilles installed during construction. Folding doors and grilles are manufactured solid panels, fabric or grilles. They open and close like an accordion along a top and/or bottom guide. They are commonly installed in locations where spaces need to be divided.

This topic includes information related to access doors and panels installed during construction. Access doors and panels provide access through a floor, wall or ceiling to concealed spaces that commonly contain systems of a structure. Doors, panels and frames are manufactured products.

This topic includes information related to vents installed during construction.  Vents provide air movement and ventilation for a variety of spaces within a structure.  They are not mechanical, rather they rely on the passive principles to cool a space.  Vents should also prevent the undesirable elements, such as rain, snow and debris from entering into a space.  Spaces that are typically ventilated in a residential structure include the attic and crawlspace.

This topic includes information related to special function glazing installed during construction.  Special function glazing offers glass with specific characteristics for applications that require additional protection or unique construction.

This topic includes information related to vinyl windows installed during construction. Vinyl windows are budget friendly, durable windows that offer various design options for both new and replacement installations.

This topic includes information related to coiling doors and grilles installed during construction. Coiling doors and grilles are manufactured from materials that offer the ability to mechanically or manually coil. Coiling doors and grilles are commonly installed in counter, garage and storefront applications.

Roof decking pavers have created new opportunities for otherwise lost and unusable spaces.  Roofs and decks now have the ability to be functional, attractive exterior pedestrian plazas and living environments.  Pavers can be installed on roof decks and promenades, terraces, balconies, patios, plazas, arenas, roof gardens, and even on mechanical access walkways.  Roof decking pavers come in a wide variety of colors, finishes and textures.  Because of it's durability and strength, concrete is the primary material used to produce roof decking pavers.

Modified bituminous roofing systems are available in two materials which are commonly used today for low-sloped roofing applications: Atactic Polypropylene (APP) and Styrene-Butadiene-Styrene (SBS). The primary purpose for both of these materials is to provide the weatherproofing cover for the roof assembly. Crude bitumen is a hydrocarbon created naturally from petroleum, and modified bitumen is a blend of other organic materials with a polymer additive of either atactic polypropylene or styrene butadiene styrene. Atactic polypropylene is a plastic additive that gives rigidity and tear resistance to the final product, and styrene-butadiene-styrene is a rubber additive that gives more resilient benefits. These blends are then applied to a base material of polyester or fiberglass. Sheet asphalt paving (mastic asphalt concrete) makes up the majority of bituminous products used in the U.S. Even though bitumen is sometimes referred to as tar or tar-like in its consistency, it is not to be confused with tar. Tar is a product manufactured from coal and is not used as a part of this roofing system.
