The structure covering membrane is the barrier between the environment and the commodity inside. This attribute is so important that Rubb uses only the best quality materials with high specifications and proven lifetime performance. We would expect the cover to last a minimum of 15 years, extending up to 30 years depending upon use and location.

Single skin is the normal industry standard which provides virtually no insulation properties. It is usually specified when used as an unmanned warehouse or storage facility.

Double skin and insulation is unique to the Rubb group of companies and has been specifically designed to provide more acceptable working conditions for front-line aircraft hangarage and vehicle maintenance workshops, in both hot and cold conditions. The outer skin insulation and inner skin are all welded into one Keder track.

Keder

Keder is the component that secures the PVC skin to the metal structure. This material is widely used in the commercial tent and marquee market but because of the forces involved and the need to install and operate in arduous conditions, we have developed an enhanced version to our specifications, with large weld area and less friction.

Blackout

Normal fabric has three layers: a polyester woven fabric inside PVC coating on both sides. This setup is ideal for commercial applications where minimal light transmission will come through (strong sunlight). In some military applications this is not acceptable and for this reason an upgraded formulation with an additional black layer has been adopted and used on the outer skin of all EFASS structures. This provides full blackout capabilities.
