b"Installing Sound Control WindowsWindows and doors have always been center to the separation of the outside environment and the inside living area, but the benefits have usually been limited to cold, heat, sun, rain andother weather related variables.Exterior noise is becoming more of a focus when improving homes because noise pollution becomes more of a problem as areas become built up and traffic and other transportation caused noise is being identified as harmful.The trend began from two sources. One has been the need tohelp homes built around airports to insulate the living areasfrom the noise of big jets taking off and landing. The other hasbeen the unexpected benefit of improving glass technologieseither by multiple panes for energy efficiency or lamination forprotection against impact breakage.TYPES OF SOUND CONTROL GLAZING Sound travels through windowsand doors via air infiltration(think of an open window ver-sus a closed one) through theunit and due to vibrations inthe window's glazing and framecomponents. To reduce soundtransmission, improvementscan be made to include weatherstripping to reduce air infiltra-MONOLITHIC GLASS LAMINATED GLASS tion, using multiple panes ofglass and other materials ofvarying thickness, and evenadding a storm window (insideor out) to create an additionalbarrier.So, interrupting the sound pathby interrupting air flow, or vibration path or decreasingASSYEMTRICAL GLASSLAMINATED INSULATING GLASS sympathetic vibration by increasing the space betweensurfaces or making touchingsurfaces of unequal thicknessare the most effective methods.Singularly they can make a dif-ference.
