Pergola / August 25, 2018 / JulietteHughes
Depending on the type of fabric used these pergolas may avoid the transmission of heat which could cause fading or damages to the roof. A tough and durable fabric that may usually be used in the making of the sails of a boat can also be used to filter ultraviolet rays and other harmful natural elements such as sunlight and heavy rain so that people can enjoy their investment for a long time. Comparative Study of Roofing Materials for a Pergola Permanent structures like metal roofs are difficult to change but they can be repainted. Fibreglass and clean plastic materials may change colour after a period but they can be discarded and new ones can be installed easily.
Plastic and Fibreglass Another variation of roofing for pergolas includes using plastic or fibreglass. The advantage of these options is that they are lightweight and inexpensive. They may also be easily cut to size and allows the light to filter in depending on the colour of the roof. They also protect the pergola from the harsher elements of the weather including the rain and snow. Also ultraviolet radiation may be reduced when using these two options. Although plastic may not be a green choice Fibreglass can be manufactured from recycled materials. Polycarbonate Polycarbonates are thermoplastic polymers which can be easily moulded and has a high impact resistance along with other advantages such as heat resistance ease of shaping flame retardancy and toughness.
To paint a pergola for lasting protection it is important to follow the traditional procedures such as preparing the surface which include removing old paint using sandpaper to permit absorption and applying preservative towards the end of the painting. Preparation of the surface is very important before painting as it decides how much time the effect of painting will last. Any remnants of oil or dirt on the surface of the wood should be removed thoroughly. Using sand paper with 50-60 grit create an appropriate surface for good absorption of paint. If the wood is more than two weeks old or if it had been lying outside in rain sanding brushing and cleaning becomes essential.
