The design of a pergola depends on the location. The pergola may be a gazebo, a building extension, an open terrace or a veranda with grapevines crossing a latticed town depending on the area, grade or direction of the sun. The roofing structure and shape of the roof on a pergola depends most importantly on the availability of direct sunlight and the geography and natural characteristics of the region. While pergolas were built using stone and brick pillars in previous times, modern designs use weather-resistant wood, like western red cedar or redwood coastline. Pergola roofs can range from a simple, flat, traditional roof, sophisticated curved roof, roof pitching, roof-top or gazebo roof style.
For centuries pergolas were typically used for adding a shaded walkway, for connecting pavilions or for a sitting area allowing the breeze and sun to filter through. This incredible addition to a home not only increases comfort but can also offer an attractive bonus to the home’s resale value. Any open space around the house can be used as a pergola invitation. Pergola structures have over the years been adapted to the area so that a wide variety of designs is available. The current designs focus most on the protection from harsh natural elements such as rain, snow and ultraviolet radiation, while traditional pergolas are mainly intended for beauty and comfort.
A variety of roofing materials are available. Depending on the size, design and structure, the choice of topping materials is determined. The construction’s long service life and robustness depend on the materials chosen for this purpose. Metals, plastic, fiberglass, polycarbonate, fabric etc. are currently used for roofing. The benefit of a metal roof is that it can be precisely fitted to the size and form of the structure. Metal roof The decision is also made by choosing metals like copper, aluminium or tin. Not only are metals easy to cut and shape, but they also offer excellent weather protection. They also have certain disadvantages, however, such as not allowing light into the area or allowing the temperature to get too hot within the zone.
Regarding translucent roofs (tam lay sang composite, rooflight, transparent panels,…), there are 2 popular materials: composite (fiberglass reinforced plastic, and
The roofing for pergolas is further modified by the use of plastic or fiberglass. These options are advantageous because they are light and cost-effective. They can easily be cut into size and filter the light according to the color of the roof. They also protect the pergola against harder weather conditions, including rain and snow. In addition, the use of these two options can reduce ultraviolet radiation. Although plastic may not be a green choice, it is possible to produce recycled materials from Fibreglass.
Polycarbonate Polycarbonates are easy to mould thermoplastic polymers that have high impact resistance and other benefits such as heat resilience, ease of shape, flame retardance and hardness. They can be used for different thermal transmission and transparency requirements. Polycarbonates are also well-known for their ultraviolet radiation protection. Polycarbonate can be made to withstand very specific and harsh environmental conditions in Australia with a wonderful combination of colours. Astrolite and Laserlite are the two most common brands in use.
