Glossary I - N
I
Illuminated Awning: A lighting system placed behind the awning material causing it to be illuminated.
J
Jacquard Weave: The type of weave to be seen in damasks, brocades, trapestries, and other complicated cloths. Made n a Jacquard loom which provides mechanisms to control the action of each warp yarn individually, if necessary.
L
Lacing: This is the most traditional technique of attaching a fabric cover to an awning frame. Grommets are placed along the edge of the fabric cover. The cover is tied to the frame by lacing thin rope through the grommets.
Laminate: Laminated fabrics are made of two or more plies fused together under a combination of heat, pressure, and adhesives. Welblon, Herculite and Lam-A-Lite are examples of laminated fabrics.
Laminated Fabric: A three-layer fabric, normally constructed of a plastic top and bottom layer, and an intermediate scrim layer.
Lateral Arm Awning: These awnings resemble typical traditional triangular structures except they rarely have end fabric panels. They also include a manual or electric cranking system that allows the awning to be folded up or retracted against the wall.
Load: A load is anything that causes force to be exerted on a structural member. 1) Dead Load: This is the self-weight of the awning or canopy frame, fabric and hardware. This load must always be included with other design loads since it is always acting on the structure. 2) Wind Load: Basic wind load is a function of its wind speed. Basic wind pressure can be computed as the product of 0.00256 times the square of the wind speed (mph). 3) Snow Load: A load imposed on a structure from snowfall. Snow leads vary considerably from region to region. 4) Live Load: All changing loads exerted on a roof.
M
Malleable Iron: A cast ferrous alloy consisting principally of iron and carbon which is made stronger and ductile by heat treatment (annealing). The heat treatment removes the brittleness normally associated with most cast iron and adds resistance to breakage under heavy impact or distortion.
Mesh: Any fabric, knitted or woven, with an open texture, fine, or coarse.
Mildewproof: It is unlikely that any fabric can be rendered permanently mildewproof under all conditions."Mildew Resistant" is a more proper term. This usually refers to a treatment on a cloth with various non-toxic chemical compounds that poison or discourage the growth of mold and fungi. Effectiveness is directly proportional to the type of fungicide and the quanity of fungicide contained in the finished cloth(to the point of maximum potency). The treatment may be durable or non-durable.
Modacrylic: Generic name established by the Federal Trade Commission for "a manufactured fiber in which the fiber-forming substance is any long-chain synthetic polymer composed of less than 85% (but at least 35%) by weight of acrylontrile units, except when it qualifies as rubber".
Modulus: This is a measure that tries to explain how a fabric reacts when it tensioned and relaxed. It is used to expain things like snow and wind loads, elasticity, memory, stretch, and shrinkage.
Monofilament: A single filament of man-made fiber used as yarn.
N
Natural Fiber: Any organic fiber such as cotton, jute, manila, or sisal.
Non-Woven: Neither woven, knitted, nor spun. A material made of fibers in a web or mat held together by bonding agent.
Nylon: Any of a family of high strength, resilient synthetic materials, the long-chain molecule of which contains the recurring amide group CONH.
