GREENHOUSE GLAZING
Polycarbonates
(PC) are a group of thermoplastic polymers containing carbonate
groups in their chemical structures. Polycarbonates used in
engineering are strong, tough materials, and some grades are
optically transparent. They are easily worked, molded, and
thermoformed. Because of these properties, polycarbonates find
many applications. Polycarbonates do not have a unique resin
identification code (RIC) and are identified as "Other", 7 on
the RIC list. Products made from polycarbonate can contain the
precursor monomer bisphenol (BPA). Glazing, which derives
from the Middle English for 'glass', is a part of a wall or
window, made of glass. Glazing also describes the work done by a
professional "glazier". Glazing is also less commonly used to
describe the insertion of ophthalmic lenses into an eyeglass
frame.
Common types of glazing that are used in
architectural applications include clear and tinted float glass,
tempered glass, and laminated glass as well as a variety of
coated glasses, all of which can be glazed singly or as double,
or even triple, glazing units. Ordinary clear glass has a slight
green tinge but special colorless glasses are offered by several
manufacturers. Glazing can be mounted on the surface of a
window sash or door stile, usually made of wood, aluminium or
PVC. The glass is fixed into a rabbet (rebate) in the frame in a
number of ways including triangular glazing points, putty, etc.
Toughened and laminated glass can be glazed by bolting panes
directly to a metal framework by bolts passing through drilled
holes.
Glazing is commonly used in low temperature solar
thermal collectors because it helps retain the collected heat.
