Most of the vinyl pergola kits are made with 100 percent virgin vinyl. These vinyl materials are free from all issues and have the necessary thickness, tensile and impact strength and mono extrusion. They are available with decorative trim, decorative corbel ends, base trim, post capitols and post accents. They can withstand any type of weather conditions and need only a simple cleaning with a garden hose now and then. They are almost completely maintenance free. They are offered lifetime warranty and even if they are a little costlier than their counterparts, it is worth investing on vinyl pergolas. It is not surprising that they are favored by the majority of people.
