acoustic properties of building materials for noise control

acoustic properties of rubber and plastic. the known materials are vinyl, neoprene etc. these materials are used to make low cost economical acoustical devices. but their use is almost considered limited. they can be used as mechanical isolators for floating glass, by preventing vibrations of the diaphragm to be transmitted to the walls. read more:

what are the advantages and disadvantages of wood? - quora

benefits of wood. 1. thermal properties: wood needs virtually doubly quantity of warmth energy than stones and concrete; equally, thrice of energy is required for heating or cooling steel. 2. acoustic properties: sound energy loss as a results of friction is additionally considerably low in woods owing to its lightness and structure. 3.

mechanical properties: wood lumber versus plastic lumber

thus, although it is inferior to wood in several mechanical properties, for some structural or semi-structural functions, plastic lumber and thermoplastic composites are alternatives to wood lumber. in addition, the use of high-aspect-ratio fillers and specific fibre orientations are effective ways to produce thermoplastic composites with mechanical properties that are closer or similar to those of wood.

plastic lumber possibilities - green building solutions

as a substitute for treated lumber, plastic lumber products resist insects, rot, moisture, and many chemicals. there are two different types of plastic-lumber productsthe composites wood products made from a mix of plastics and natural fibers and the wood-like products made solely from plastics.
