Study Notes
Glass Types
- Low-iron glass transmits visible light while selectively reflecting longer wavelengths of radiant heat.
- Solid glass block units are impact-resistant and sometimes coated to reduce solar heat transmission.
- Hollow glass blocks are translucent, made by fusing two halves together with a partial vacuum inside.
- Laminated glass consists of two or more piles bonded under heat and pressure with interlayers of polyvinyl butyral resin that retain fragments if the glass is broken.
- Tempered glass is impact-resistant and used for safety reasons in certain applications.
- Heat-strengthened glass is reheated to just below the softening point and then rapidly cooled to induce compressive stresses in the surfaces and edges.
- Opaque glass is obtained by adding metallic oxides to the glass mixture.
Glass Coatings and Finishes
- Low-emissivity glass is created by depositing a material on the glass.
- Ceramic frit is fused to the interior surface of opaque glass to produce an opaque finish used for concealing structural elements in curtainwall construction.
Tile Types
- Ceramic tiles have a non-vitreous body and a bright matte or crystalline glaze.
- Porcelain tiles are small, made from porcelain or neutral clay, and can be glazed or unglazed for use on both floors and walls.
- Mosaic tiles are usually faced or back mounted on sheets to facilitate handling and speed up installation.
- Terra cotta tiles are made by the plastic method from natural clays and have highly colored opaque glaze.
- Body tiles are composed of the same ingredients throughout and derive their color and texture from the materials of which the body is made.
Glaze Types
- Bright glazes have a shiny surface, while matte glazes have a dull surface.
