Current Situation and Solution: Application of Sail Canvas Awning in Modern Architecture
The Hypar canvas canopy is an optimal architectural solution, especially suitable for projects requiring structural simplicity. By taking advantage of the tension of the reinforced canvas stretched across multiple points, this solution creates relatively wide spans, providing a large shade area and ensuring ventilation for the space below. High adaptability allows the canvas canopy to be applied to a variety of modern architectural projects.

Technical Requirements Analysis & Solution Context
Architectural projects today often seek roofing solutions that not only ensure protection from the effects of weather, but also meet aesthetic criteria, optimize space and construction costs. Traditional roofing is often heavy, limited in span capacity and requires complex support structures. This context creates a need for a lightweight, flexible solution that can be uniquely shaped and easily integrated into the overall landscape, while ensuring safety and effective drainage.

Technical Solutions
Flexiiform's sail canvas canopy solution uses the Hypar (hyperbolic paraboloid) structure, one of the typical structures of Tensile Membrane Structure. The structure and technical characteristics of this solution are described in detail below:
Hypar structure and operating principle
The Hypar structure is simple in construction, consisting of a canvas section that is calculated and arranged into high and low points, creating a characteristic three-dimensional shape, similar to a sail. This is a stable and durable roof structure, with the ability to withstand large loads from rain and snow. Modern engineering technologies allow for the precise calculation of the required tension, helping to maintain a solid structure while creating the perfect shape desired by the design.
Technical and material advantages
The canvas canopy with sails offers three outstanding advantages:
- Natural light: The membrane fabric is translucent, ensuring the ability to shield the building from the effects of harsh sunlight and UV rays, but still allowing natural light to diffuse well and evenly into the space below.
- Light-weight: The sail canvas canopy weighs only one-thirtieth of the weight of traditional constructions, significantly reducing the load on the foundation structure and support frame.
- Safety: With its elastic properties and tensile structure, tensile fabric roofing can prevent objects from falling from above by bouncing them off the roof surface, minimizing the risk of breakage compared to hard materials such as glass or corrugated iron.
Common types of tarpaulins used for sail structures include coated tarpaulins (such as PVC/PES coated with PVDF) and mesh tarpaulins. Coated tarpaulins are woven and coated on both sides, while mesh tarpaulins have small gaps between the interwoven yarns, allowing more light to pass through, and are often used for swimming pool covers or other indoor/outdoor areas that require shade from the sun and rain.
Notes in design and construction
To optimize the ability to shield and ensure technical efficiency, the roof shape depends largely on the influence of the current state of the building and existing trees. The load-bearing frame system can utilize the structure of existing buildings (concrete beams or columns) to minimize material costs. In particular, the roof slope needs to ensure easy drainage of rainwater and avoid water stagnation, with a reasonable slope usually not less than 7 degrees compared to the horizontal plane parallel to the ground. For large structures, a separate solution is needed for roof areas that are not steep enough to maintain flat tension.

Results and Performance Evaluation
The sail canvas canopy has been widely used and brought high efficiency in many outstanding projects. For the rooftop garden spaces of commercial centers, the canopy has a unique and novel shape, large span but simple load-bearing structure to increase the usable space. For outdoor walkways or walkways of buildings, hospitals, schools, the sail canvas canopy helps optimize space, while combining translucent materials to create beautiful shadow effects. In the lobby areas of buildings, commercial centers, schools, hospitals, the sail canvas canopy creates an impressive and modern reception space.
