We have noticed a growing trend online for our competitors to boast a thicker product as a superior product. We are going to dispel that myth. The thickest vinyl/PVC you will find on the market is typically found in PVC pipe. PVC pipe can be in excess of 1/4 inch thick. If you have ever looked at a PVC pipe that has been left outside for a year, you will notice that it has yellowed or turned brittle. That is due to the lack of impact modifiers and TI02/Titanium Dioxide. Just because a vinyl fence profile is thick does not mean that it will hold up to the elements.
