DAS Vision of inflatable structures. http://dassarl.e-monsite.com/ When it comes to inflatable products, many people think of bouncy castles, parade floats or dancing tubes used for advertising. But the world of air-supported structures, or inflatables, extends far beyond the use of entertainment and advertising to industrial, military, architectural and aerospace applications. Whether they’re used as a portable shelter or a payload landing on Mars, air-supported structures offer numerous benefits over traditionally built alternatives. Typically, inflatables are a more elegant engineering solution because they are simple by design . In addition, they require fewer mechanical parts, and they pack tightly and take up very little volume.” Inflatables provide some eco-friendly benefits as well. DAS http://dassarl.e-monsite.com/ . “In today’s world when energy and its conservation are in the forefront of development, inflatables offer a low-energy production alternative to comparative products. This advantage is growing by the use of recyclable fabrics, water-based coatings and low-energy fans and blowers.
Expanding applications DMSTM (Double Membrane System) is Duol innovative solution with specially designed air pockets which greatly reduce energy consumption. DMSTM comes with three variants. Standard DMSTM provides thermal insulation of 3.05 W/m2K, while DMS PlusTM provides thermal insulation down to 1.74 W/m2K and E-DMS PlusTM down to 1.43 W/m2K (measured by independent test institute). DUOL DMSTM DMSTMthermo (Double membrane system without thermal bridges) is available for best thermal insulation. Standard Duol membranes are UV resistant, but with use of a special lacquer finish like PVDF TiO² this resistance is even better, which increases the material's quality and lifetime
DURABILITY / LIFE EXPECTANCY In DUOL double membrane systems, the replacement of the membrane is not required and the life expectancy is extended to 40+ years based on tests, experiences and existing projects. NATURAL LIGHT As both membranes are highly translucent, the use of a lighting system is not required during the daytime, which leads to big savings on electricity. FIRE RESISTANCE All membranes are fire retardant, certified by the following certificates: M2/NFP 92-507, TEST 2/NFPA 701, CSFM T19, B1/DIN 4102-1, BS 7837, B1/0N0RM B 3800-1, M2/UNE 23.727, VKF 5.3/SN 198898 and others. RIGIDITY With mechanical resistance and specific porosity design, our fabrics provide excellent dimensional stability, structural strength and wind protection. Thanks to the DUOL expanded double membrane system, the DUOL domes are very rigid and vandalism resistant. In case of anydamage to the outer membrane, the inner membrane will remain air tightand retain its pressure and stability. STORM PROTECTION A DUOL dome has an automatic safety back-up system, which controls the air dome pressure and stability in case of storms and high winds. SNOW The shape of the air dome is designed to withstand local weather conditions. A totally flat surface and lacquered finish, ensures that the snow slides off the air dome. CONDENSATION Thanks to excellent insulation, achieved by the DUOL expanded double membrane system, there is no condensation inside the air dome. ENVIRONMENTAL COMMITMENT Lightweight and durable, Duol fabrics are also 100% recyclable. DUOL implements an advanced membrane coating, which is selfcleaning to preserve a perfect white colour membrane for many years and for many dismantling and assembling procedures. AESTHETIC PERFECTION Duol membrane technology guarantee that DUOL air domes are objects of admiration among visitors and the local community and are places where people love to gather. YOUR BENEFITS: • High and consistent transparency & luminosity • Whiteness, visibly cleaner surface • Greater resistance to chemicals • Lower cleaning costs • Ecologically friendly due to reduced energy consumption and water usage for cleaning • Folding of the membrane doesn't cause damage to the coating materials. This offers easy storage of the membrane during seasonal removal. Transparent membrane Playing indoor while having a 360 degreespanorama view. Attractive design from inside and outside: The transparent air domes offer an indoor view while catching views from people outside. Duol transparent membrane offers, best on the market, 64% lights transmittance. Due to the high transmittance of daylight, lighting costs can be reduced which in turn will contribute to saving energy.
The SpaceDomeTM insulation system developed by Duol is the only air-dome insulation system to efficiently reduced all three types of heat transfer: conduction, convection and radiation. It is made from high-tech materials developed for space technology with the lowest thermal conductivity of any solid material. The SpaceDomeTM has a better thermal performance than the standard double membrane system. With theSpaceDomeTM system, air dome heating and cooling costs are reduced to the level of a conventional building, which is an outstanding achievement.
The Duol DMSTM membrane system provides resistance to harsh climatic conditions and ensures high heat insulation. For maximum energy savings, DMSTMThermo and SpaceDomeTM insulation system are available. Duol heating units safely and efficiently heat the air structure to the desired temperature and humidity. The Air conditioning system is also available and is custom-designed for each project’s specific requirements.
What to consider The fabrics, coatings and finishing of inflatable products all contribute to their successful operation. In terms of selecting materials: • • • • • • • •
Tensile strength in both warp and weft of the fabric Tear and rip resistance to reduce accidental damage Coating adhesion to the fabric under all conditions of operation Weathering resistance and the ability to easily clean, including resistance to UV degradation, abrasion resistance and retention of physical properties after long periods of exposure Suitability of the material for joining techniques, which retain the full strength of the base material and integrity and properties of the coatings Pliability and flexibility to prevent damage during packing, storage and handling, as well as ability to shape conform to applied pressures and forces Fire-retardant properties and flame spread resistance to meet fire and safety codes Translucence or opacity, along with insulating properties as the application require
Coatings, meanwhile, contribute to an inflatable’s pliability, weather resistance, durability and color/opacity.
Growing bigger As technology continues to evolve in the world of inflatables, so will the markets and opportunities.
“The need for reliable, lightweight and compact shelters that can be rapidly loaded and deployed will be ever growing,” . “Inflatable products are the only things that meet these requirements.” For support, pressure, cushioning and space filling, inflatables are a great solution. With a world that is always looking for ways to reduce cost, what materials are less expensive than an air-filled inflatable?
