The Membrane

Membrane fabrics are available in a variety of colours, weights and levels of translucency and are flame retardant and treated for resistance to UV, cold crack, mildew and chemical pollutants.


Available qualities of membrane fabrics range from the basic acrylics for temporary structures to state of the art quality fabrics for permanent structures.
Warranties are available up to 20 years depending on the quality of the fabric's top finish and the fabrics in general outperform these warranties.

Inner Liner

An inner liner fabric provides insulating and acoustic characteristics by itself and the way the inner liner is attached to the outer membrane, hanging loose (not stretched) enhances insulation value and acoustics even more. The fabrics we use reduce sound waves instead of reflecting and the result is a “hushed” atmosphere without echo effects, which allows for crisp, clear sound travel for conversation or when addressing a group or an audience.


The liner fabric also has great light dispersing properties which combined with the indirect light system results in a very cost effective, pleasant light that spreads evenly over the courts or field covered by the dome.


The lower part of the inner liner is usually coloured for a good ball visibility.

100% Dielectric Welded Construction

Dielectric welding of the fabric by use of radio frequency is recognized as the highest quality seaming. RF welding creates a durable water tight seam with strengths exceeding that of the fabric itself. 100% of the seams in our air supported structures are dialectically welded to ensure complete architectural integrity.


Anchoring System

A foundation is needed to overcome the uplift of the building, created by the building’s internal air pressure


We use an aluminium extrusion “channel,” integrated in the reinforced concrete grade beam for anchoring the membrane. This is a very airtight system and also the fastest, easiest system for seasonal put ups and take downs of domes.


Cables are added to larger domes and to domes in high wind load areas.


Insulation

In structures that require temperature control you can consider insulating your air structure to reduce heating and cooling costs, as well as to make your dome environmentally friendly.


Lighting System

The lighting system is usually included in the dome package. Depending on the application, we can offer both a hang light and a stand light system or a combination for your air-supported structure project. Upgrading to a LED lighting system will usually be payed back in a short time.

The indirect light is reflected by the internal liner with light dispersing properties to provide an even, pleasant level of lighting for the required activity and with adding direct light we can also deliver a light system allowing for television broadcasting.

A skylight system, bringing in filtered daylight, reduces and sometimes eliminates the need for daytime lighting, which can save considerably on running costs of the facility.
In more moderate climates or for seasonal structures a translucent membrane can be considered for maximum saving on energy for lights. 

 

Inflation Equipment, Heating and Cooling

In most situations inflation equipment for air domes will consist of fans; a primary fan for normal use and a back-up system of a second blower usually combined with a self-start generator to ensure the dome’s safety in the event of equipment or power failure. This back-up system will also kick in to remain the pressure in the dome in case of damage to the membrane.


Heating and cooling (AC) equipment can be added to the dome package to create a comfortable indoor environment year round and the equipment is custom built to accommodate specific dome size and climate requirements. 

 

Dome Access and Egress

We use revolving doors in combination with a personnel airlock to get people in and out of the door without compromising the internal air pressure and our emergency doors are specially designed centre-balanced doors coming with the appropriate emergency exit signs and lighting.


A vehicle airlock makes access to the dome easy for bringing in larger equipment.


Seasonal Buildings

The design of a seasonal building has a few small additional considerations. The size of each dome section is smaller for easier handling, fabric selection is a consideration and the anchoring system should be totally concealed. We will design these features in from the start for seasonal applications.
