If fire is held to the vinyl, it will burn. But as soon as the source of the fire is taken away, the vinyl will self-extinguish. Yellowing and fading in vinyl products are due to the sun's ultraviolet rays. This amount of TiO2 is more than sufficient to prevent breakdown from the sun's ultraviolet rays. Heritage's vinyl formula exceeds the industry standards to guarantee you a lifetime fence or deck.
All materials expand and contract with hot and cold temperatures.
Impact modifiers add flex to Heritage Vinyl so that the product will give instead of crack or splinter like wood. Only under extreme circumstances will Heritage Vinyl crack. Heritage Vinyl flexes as a safety measure. This is especially important for Ranch Rail fences that contain beloved horses and other valuable livestock. Heritage Vinyl is a maintenance-free product.
