Our SoundTITE Optical Grade Acrylic Windows can provide up to 115% better thermal resistance than a single pane of glass.
Glass: 5 to 6 btu/hr/sq ft/°F, according to CRC Handbook of Chemistry
Acrylic: 0.7 to 1.7 btu/hr/sq ft/°F,according to Handbook of Plastics (indicates that acrylic is up to 8 times more thermally insulating than glass)
U-value of .48 in combination with single pane window, as determined by John M. Yellott Laboratories, Arizona, in tests performed.
Heat loss reduction of 412.5 btu/hr/ft sq (from 687.0 to 274.5) when applied to single pane window. As determined by Architectural Testing Inc., York, PA, in tests performed.
Our SoundTITE Optical Grade Acrylic Windows are 17 times stronger than a single pane of glass.
Which means that they are virtually shatterproof
Our SoundTITE retrofit double glazing can reduce noise by 70% through your existing window
Sound Transmission Class (STC rating) is used to measure the resistance to noise that will pass through a partition. The STC Rating can improve from 28 (Dual 1/8" glass panes with 3/8" air space) to 41 when SoundTITE is added. The effective sound transmission reduction is over 70% (Particularly effective in 250-4000 Hz range) As determined by Acoustical Systems, Austin, TX NVLAP Lab Code# 100286-0, ASTM-E90 Test AS-TL2739.
Ultraviolet light waves between 300 and 355 reduced by 99.1% when passing through acrylic sheet and UV light waves between 360 and 375 reduced by 66.2%. As determined by DSET Laboratories, Inc., Phoenix, in tests performed.
Virtually all air infiltration is eliminated.
A SoundTITE window air infiltration is rated at less than .01 cfm/lineal foot crack space, compared to DOE standard for storm windows of 2.0. Tested with 25 mph wind equivalent at The Associated Laboratories , Dallas, using ASTM E-283 test method. Similar results at the John M. Yellott Laboratories.
What is an STC Rating?
STC stands for Sound Transmission Class.
STC ratings are a standardized way to measure how much sound is stopped by a specific material.
The STC rating is the average amount of noise stopped at 18 different frequencies, measured in decibels.
What is the STC Rating on my existing single pane windows?
For single pane windows, the average STC Rating is 26. By comparison, the STC rating of a typical interior commercial wall (filled with R-13 Insulation), is 43.
Understanding the STC Scale:
STC ratings are a logarithmic scale similar to the earthquake Richter Scale - Each number is exponentially higher than the one before. A 10 db increase in an STC rating is equivalent to a 50% decrease in noise.
For example: A window with a single pane of glass has an STC rating of 26. A solid core door has an STC rating of 36. (A difference of 10 db) Which means the solid core door would reduce noise 50% better than the window.
Is 100% Noise Reduction Possible?
SoundTITE Windows cannot eliminate 100% of the noise, but sound can be reduced by 70%. In some cases less noise will be coming through the SoundTITE Windows than the walls.
Brand New Energy Efficient Dual Pane Windows will not Stop Noise:
A dual pane glass window might be great for energy efficiency, but it will have little effect on noise reduction.
SoundTITE Windows can be mounted with a variety of configurations:
