THE IMPACT TEST
Providing one of the toughest sidings on the market today s a result of the Dura™ Technology Process. More specifically, it envolves using proven premium ingredients and our exclusive DURA™ impact modifiers. First an impact test is performed at 73º F (23º C). Then the siding is frozen to 32º F (0º C), to stimulate 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 150%.

THE SHEAR TEST :
To ensure your siding withstands the test of time, a shear test is performed. Both the shears and siding are frozen to 14º F (-10º C) 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.

THE FLEX TEST :
A flex test bends the siding almost 180º to ensure you get a tougher, longer lasting siding. What's even more striking about this test, is that it is performed at 32º F (0º C) to ensure our siding maintains its structural integrity under the harshest weather conditions.
