A lifetime of durability begins with Royal's Dura Technology, which is engineered into a material that's considerably thicker than industry standards. No wonder it's the first choice for durability. Any installer will see the structural advantages and performance features of this sturdy and practical innovation. Your end product and practical innovation. Your end product will be a crisper, cleaner and tighter fitting siding. It's an easier way to a more secure finish.

Shear Test Shears and siding are frozen to 14F (-10C), siding is then cut into sections to ensure your vinyl siding maintains its rigidity under severe weather conditions. To ensure your siding withstands the test of time, a shear test is performed.  Both the shears and siding are frozen to 14F (-10C) then the siding is cut into sections.  The purpose of this test is to ensure your vinyl siding maintains its rigidity under the most severe weather conditions. Flex Text Siding is bent almost 180 degrees at 32F (0C) to ensure it maintains its structural integrity and superior durability under the harshest weather conditions. A flex test bends the siding almost 180 degrees to ensure you get a tougher, long lasting siding.  What's even more striking about this test, is that it is performed at 32F (0C) to ensure our siding maintains its structural integrity under the harshest weather conditions. Impact Test An impact test is performed at 73F (23C) and again at 32F (0C) to simulate harsh weather conditions, ensuring our vinyl siding exceeds ASTM standards. Royal performs an impact test at 73F (23C).  The siding is then frozen to 32F (0C), to simulate harsh weather conditions and a second impact test is performed.  This results in a vinyl siding product that exceeds the ASTM industry impact standards by an average of 158%.
