عربيAmong tensile membrane structures, the most commonly used material is polyester coated with polyvinyl chloride (PVC). It offers exceptional strength, durability, transparency and weatherability. It is suitable for both permanent and temporary applications, satisfying a variety of project needs and design demands.
PVC Membrane is manufactured from a woven polyester fabric coated with a polyvinyl chloride (PVC) coating and an additional PVDF (lacquer) coat. These top-coatings help to increase the membrane's resistance to fire and UV rays, as well as improve its strength, flexibility and weatherability.
Different manufacturers use a combination of these Top Coats, varying in thickness and translucency to suit specific project requirements. For example, a single coat of PVDF would be ideal for introducing colour and print to a structure, while a multi-coat of PVDF is preferred to achieve superior longevity in harsh environments or for projects that are expected to remain unobstructed for long periods.
Self-cleaning Property:
The surface of the PVC membrane is protected with a protective coating such as PVDF (polyvinylidene fluoride). The coating prevents dust from falling on the surface of the structure, which allows natural rainwater to clean the membrane, reducing maintenance needs and keeping the membrane bright and brighter for longer.
Energy Savings:
The white coating of the PVC membrane has excellent reflectivity and emissivity, which significantly reduces radiant heat gain and helps to keep building interiors cooler in warmer climates. It also keeps the light in the room diffuse and slow-scattered, allowing for natural daylight to illuminate the space.
