Trex Composite Fence Sound Test
When Trex Seclusions® wood composite fencing was first brought into production in 2005, Trex® wanted to make sure that they had a more superior product to the common dog-eared composite fences that were being manufactured. In December 2006, the Trex Company sent their fence product to York, PA to have it tested for its sound barrier quality. In a sound barrier test, the product is placed inside well insulated walls using three layers of 5/8” gypsum board. The wall cavities are filled with R-13 fiberglass insulation. The perimeter and seams get sealed with acoustical sealant.
A total of five microphones are used and tested before placement behind the fence panel. After the fence panel is in place, the microphones are strategically placed behind the fence panel to catch sound from one end of the panel to the other. Because air temperature and relative humidity affect sound, those tests were also performed and monitored during sound testing.
The test company used a hertz range from 80 on the low end up to 5000 on the high end. By using a wide range of frequencies, this assists in the testing accuracy of its final score. Trex Seclusions® wood composite fencing can block up to 95% of direct sound.
Knowing this, the state of Utah and the Department of Transportation installed over 17,000 linear feet of Trex Seclusions® along a light rail project. In most areas the fencing is 12’ tall. Try doing that with any other wood composite fence product on the market today. In Florida, they are in the works to get Trex Seclusions® approved for their light rail project. In Colorado, there is a 40 mile project going on to fence the perimeter of an HOA. No matter your application, keep the noise out and install Trex Seclusions® wood composite fencing.
