Glossary of Soundproof Window Terminology
the science of sound including its production transmission and effects.
AIR CONDITIONER ENCLOSURE:
an aesthetically appealing housing, made of wood, formica and glass, designed to reduce outside noise coming through an air conditioner when not in use.
the surrounding noise associated with any given environment.
the air space for acoustical and thermal containment between exterior and interior windows.
DOUBLE PANED WINDOW:
are two pieces of glass typically separated by a small amount of air or gas. Extra layers of glass are helpful in reducing noise and heating costs, but the overall benefits are not as good as a window system that has been designed for noise reduction.
DUAL PANE WINDOW:
see Double Paned Window above.
ENTRY DOOR WEATHER-STRIPPING:
a neoprene gasketing system, including an automatic drop saddle for door bottoms, installed around the perimeter of apartment/home entry doors to reduce noise and prevent air draft, dirt and odor infiltration.
is the outermost window, the one exposed to the outside air or elements.
using silicone caulking to affix glass into a frame to produce a secure seal.
HORIZONTALLY SLIDING PANELS:
framed glass or polished edge glass panels that slide from left to right and from right to left (side to side).
a window installed on the inside of an existing window to control noise, heat and dirt.
a transparent material, Polyvinyl Butyral (PVB), used in laminated glass (inserted between two layers of glass) which reduces noise, increases the glass’ safety and provides 99% UV protection.
two layers of glass permanently bonded together with a plastic interlayer between them; designed for greater sound reduction, safety, security and UV protection.
(registered trademark of the General Electric Company): one of many polycarbonate, UV stabilized glazing products available from GE; lightweight, security glazing material combines impact strength and abrasion resistance.
glass having a single uniform thickness.
any undesired, disagreeable sound, including any unwanted disturbances such as traffic sounds, street noise, car alarms, sirens, etc.
is muffling or eliminating sound.
is the removal of an existing window and replacement with a new high performance window.
the amount of solar energy that enters through a window.
the sealant of choice for structural and acoustical glazing and sealing.
SOUND TRANSMISSION COEFFICIENT (STC):
the ability of a material to minimize the passage of sound; defined as the ratio of the sound energy transmitted through a material to the sound energy incident on the material; (see sound transmission loss).
SOUND TRANSMISSION LOSS (STL):
the ability of a material to minimize the passage of sound; expressed in decibels (db) it is more commonly used than the sound transmission coefficient (STC).
are window systems that significantly reduce outside noise.
Starphire glass offers maximum transparency (5% higher Visible Light Transmittance than ordinary clear glass), High fidelity color transmission for an undistorted view, and Jewel-like brilliance and character.
framed glass or polished edge glass panels that are non-operable, but that can be easily removed from and reinstalled into the perimeter tracking system.
the regulation of warm and cool currents of air.
the horizontal dividing bar in a window which separates the top section from the bottom section.
ultraviolet rays emitted from natural sunlight, which cause oxidation and fading of colors on furniture, draperies, carpet and artwork.
a measure of heat transmission due to the air temperature difference from inside to outside.
VERTICALLY SLIDING PANELS:
framed glass panels that slide up and down.
