Bentonite Clay Foundations with habitable spaces must be protected from moisture intrusion. Bentonite clay is a type of clay that has unusual qualities of cohesion and sealing when exposed to moisture. Used as a waterproofing membrane at a fountain wall, it can provide an impermeable barrier to moisture intrusion from the soil. It cannot be ripped, punctured, or cracked. Bentonite clay can also be used under slabs. It is found naturally in South Dakota, Wyoming, and Montana and is mined for its unique qualities. Glazing Glazing Glazing is the process of installing glass in a window frame. It can also refer to the glass that has been installed through the glazing process. Compare and contrast storefront, curtain wall, and window wall systems. Storefront: a non-load-bearing, single-span glazing system that sits within the building structure and spans from slab to slab. Storefronts are often limited to a height of 10' and are mostly used at the ground floor, but they can be placed at the upper levels of low-rise buildings. Curtain wall: Non-load-bearing glazing system that "hangs" outside of the building structure and can span up to 20' (or even further with reinforcement). Curtain walls are appropriate for use in the higher floors of tall buildings, and because curtain walls often hang outside of the building structure, they can span between floors. Window wall: a non-load-bearing glazing system that spans from slab to slab, similar to storefronts. Unlike storefronts, window wall systems are rated for use in upper floors and can provide a look similar to curtain walls at a lower cost. Weathering Steel Also called corten. Weathering steel is a steel alloy that is designed to form a protective oxide coating as it weathers. Cor-ten stands for corrosion and tension. Ice Damming When warm air rises out of a heated space into an unheated roof and there is snow on the roof, the heat melts the snow and the water runs down the roof to the eave and gutter, where it cools and turns to ice, forming a dam where more water collects and leaks into the walls and ceilings of the building. Areas most susceptible to ice damming include roof eaves and valleys. USCPSC USCPSC The United States Consumer Product Safety Commission is an independent federal agency that serves to protect the public from products that may be unsafe due to risk of fire, mechanical failure, chemical exposure, or electrical malfunction. Float Glass A sheet of glass made by pouring molten glass onto a sheet of molten metal, usually tin. Also called annealed glass. Float glass is very smooth and free from distortions. Laminated Glass A type of safety glass consisting of two or more pieces of glass with layers of polyvinyl butyral resin sheet interlayers. It is good for security because the plastic interlayer holds the glass together instead of shattering. Laminated glass is also a better sound protector than regular glass, due to the inner layer. Spandrel Glass Spandrel Glass Spandrel glass is glass that is designed to be opaque and is used where vision glass is not desired, such as in a building curtain wall façade, where the glass will need to cover the features of the building at the floor and ceiling or columns. Low-E Glass Low-E or low-emissivity glass has an extremely thin (a few atoms' width) layer of metal on the surface that selectively reflects and transmits certain wavelengths of the electromagnetic spectrum. Long wave heat radiation is not transmitted but visible light is reflected. Low-E glass is often used in insulated glass units. Reflective Glass Reflective glass is coated with a very thin layer of metal with the primary purpose of reflecting radiative heat. Tempered Glass Glass that is heated to a high temperature (about 1200º F) and then quickly cooled. The heating and cooling process creates compressive stresses on the outer surfaces and tensile stresses on the inside. It is about four times stronger than float glass of the same thickness. When breaking, tempered glass shatters into many tiny pieces instead of dangerous shards. Tempered glass cannot be cut, so it must be formed in the desired size
