DUOL

Every component in DUOL air dome benefits from 20 years of

experiences and high investment in R&D.

DUOL engineers the structure to meet the same code requirements

established for permanent buildings. All DUOL’s constructions are

produced according to the European standard EN 13782.

This standard specifies safety requirements which need to be observed at

design, calculation, manufacture, installation, maintenance, operation,

examination and testing of mobile, temporary installed tents more than 50

m2 ground area. The content of this European Standard collects the

different existing national regulations and guidelines as far as possible.

DUOL’s final product is certified with ISO management system 9001 as

well in compliance with standard EN 13782, means we keep in all

calculations reserve as requested with this standard.

DUOL EXPERTISE

We manufacture, install and maintain the products

we sell. We are not simply “brokers,” selling

components manufactured by others and relying on

a disconnected group of vendors to perform the

follow up and warranty services demanded by an

air, frame or tension structure.

Our manufacturing experiences, best quality

materials and ISO 9001 production quality

guaranties you best product warranty of its kind.

Duol DMS Plus (Double Membrane System

Plus) is innovative solution which greatly reduce

energy consumption.

It is designed for extreme climate conditions, for

temperature range from -50 to +70 Degrees.

Facts are confirmed in a practice, too. DUOL

has installed domes of own production from artic

circle to the desert.

Exceptional cleanability - long term dirt resistance.

Membrane is UV resistant.

All membranes are fire retardant, certificated by 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

Exceptional luminosity. No artificial lighting is required during daytime hours. When interior lights

are used at night, the fabric‘s high gloss interior finish top coating will reflect indirect lightening in all

directions.

DUOL DMS PLUS

Thanks to excellent insulation, achieved by

DUOL double membrane system, there is no

condensation phenomenon inside the air

dome.

Long term durability thanks to a superior top

coat thickness and high tearing resistance

and tensile strength. Replacement of the

membrane is not required and the life

expectancy is extended to 40+ years, based

on tests, experiences and existing projects.

DUOL DMS PLUS

Air generator works with two functions. Air inflating

guarantees the stability of the dome; furthermore it provides the

normal living/climate conditions inside the dome by mounted

heat exchanger, heating the air before to be inflated into the dome.

DUOL heating-ventilation System is completely automatically-

controlled.

The unit could be designed also in mobile variant.

AIR GENERATORS

Improved modulating system (35% saving approximately)

Smart energy-saving mode

In calm conditions, blower units operate at only 50% capacity,

greatly reducing running costs.

Optimized combustion, thanks to condensing chamber

Reduced hot air stratification

Mounted on anti-vibration basis - quiet under 64 dbA (-30%)

Special insulated sandwich panels resistant to extreme low

temperatures

The inner ambient of the dome is lighted by proper quantity of the halogen lamps in two different

modes: directly or indirectly. At direct lighting the lamps are mounted on the membrane to give light

on the sports field directly, at indirect lighting the lamps are installed on the metal poles and light up.

Illuminating power is calculated according the dome function.

LIGHTING SYSTEM

Highly durable, low

maintenance

Energy efficient

Eco-friendly

High optical efficiency and

precise lighting control

Natural spectrum light

Housing made of steel, dust

and moisture resistant

It is many possibilities, how to connect the membrane to the

concrete beam.

The rings with peg crossed by a metal tube or grounding anchor

with metal tube are used for temporary assembling – seasonal

use of the dome.

For permanent assembling the anchoring is done by metal profiles.

The anchors are mounted in to the concrete beam in a distance 1m,

around the perimeter.

The anchoring in some situation could be done also by auger

anchors, without any concrete foundation. Auger anchors are

grounded directly to the ground in the depth of 2mt.

With DUOL advanced anchorage system air loss around the base

perimeter is greatly reduced providing savings on inflation.

ANCHORING SYSTEM

Intellergy

Intellergy (Intelligent Energy Control) is a DUOL innovative system which enables constant real-

time supervision of the air domes activity and vital technical data with alarming.

INTELLIGENT ENERGY CONTROL

Duol heating units safely and efficiently heat the air structure to the

desired temperature. Humidity inside the structure is controlled by DUOL’s

innovative heating-ventilation system.

DUOL Duol DMS Plus guarantees resistance to harsh climatic conditions

and ensures the highest temperature isolation.

Air Conditioning is available as well, and will be custom designed for each

project’s specific requirements.

ALL WEATHER COMFORT

DUOL air domes are located around the world in a variety of

climates. DUOL air supported structures are designed and

engineered to withstand most of unusual weather conditions and

natural disasters.

INNOVATIONS

DUOL is the leader in air supported structures because of our large technological advantages

resulting from 20 years experiences and high investment in R&D. Every DUOL air supported

structure incorporates the latest innovations in design, membrane system, air management,

lightening system and electrical systems to provide the ultimate in efficiency, safety and comfort

for our clients.

One of DUOL most important innovation in year 2011 is new insulation system – SpaceDomeTM. SpaceDomeTM is made using the

aerospace materials which technology experts consider to be best insulation material ever invented. SpaceDomeTM allows five times

better thermal performance in comparison to standard double membrane system. With this DUOL's achievement air dome heating and

cooling dome costs can be reduced to the level of a conventional building, which is outstanding achievement.

QUICK ASSEMBLING

DUOL own production facility

enables us to design,

manufacture and install turnkey

structures in a matter of weeks

after design approval.

Installation is simple, quick and

cost effective and for smaller

domes takes only 1-2 days.

QUICK ASSEMBLING

MINIMUM INVESTMENT - MAXIMUM RETURNS

DUOL air supported structures are revolutionary structures offering unparalleled cost benefits

over conventional construction methods. Cost of design, manufacture, site preparation and

installation are all a mere fraction of those of conventional construction. Unlike traditional

structures, Duol structures also require less paper work.

AIR DOMES

SEASONAL STRUCTURES

Quite often it is profitable to have the air structure in place only for wintertime activities and remove

air dome during the summer months.
