The art of building with Air


Jan. 2010

Brief history... Inflast Project: “New methodologies for Design and Manufactoring of Inflated Structures� Finished: November 2000 Objective: Apply inflatable technology developed in the aerospace industry into the civil and architectural field. Therefore we created in 2001 Buildair moved by the market technology transfer

AirTecture Buildair is a company specialized in offering solutions for shaping space. Our goal is to offer the most advanced engineering, design and manufacturing technologies in inflatable structures We invite you to learn more about Airtecture, “the art of building with air�. 3

Integral Space Solucion • Design, engineering, and fabrication of inflatable structures. • Integral solution for your space: flooring (platforms, carpeting,

etc) air conditioning and decoration of your inflatable structure.

• Illumination: There are various and new ways to illuminate your inflatable structure from inside its tubes, granting greater notoriety and beauty.

• Calculation of membrane structures (textiles), using methods of finite elements, considering the fluid- structure interaction, in order to estimate wind effect.

Very High Security level We use treated fabrics with at least a flame retardant M2 Classification (UNE 23.727) Our structures are made of a very strong but light fabric. If it is intentionally cut the constantly working air-turbines provide stability to the structure and the repair kit allows our customer a quick fix to these situations. Even if the damage was great, the structure is quite light (300gr/m2 apx.) and it would rarely compromise the security of the visitors.

+ Advantages Security: A Light structure based on air, ensures the highest levels of safety to its users. Support: Our Engineers and Architects elaborate a technical memory of each inflatable structure, which is approved in the corresponding professional college, in order to enable or facilitate the legal permissions to locate your event in public emplacements, and guarantee our client the fulfilment of effective regulations. Flexibility: with our inflatable structures, size is not a restrictive factor. They can be created of any dimension. For a greater flexibility we make them by modules, which can be divided to create independent smaller spaces. Portability: Ease of transport and storage. The structures fold down into smaller modules from: 656 ft2 to 6.5 ft2 Easy to assemble: Minimum effort required to assemble and disassemble. Specialised staff is not necessary to inflate the structures. Silence: The inflating system consists of silent turbines of continuous low-pressured air, which are settled inside tubes. Independence. Additional infrastructure is not required on site. Protection: Very good levels of thermal and acoustic insulation. 8

An Inflatable Structure - The inflatable building is formed by low pressure tubes, aligned parallel to each other forming a "rib-cage" structure. - Structural stability of the inflatable structure is guaranteed both lengthwise by the support of the lateral air tubes, and crosswise through the internal pressure in the tubes.

Architectural Design With our technology, form and size have no limits. We have designed and produced inflatable structures bigger than 2.000m2.

Our inflatable structures are completely customized to meet the wishes of our customers, having in mind functionality and the objective or idea that our client wants to communicate. 11
