Cases and Solutions

Over the years, both the Technical department and sales consultants at RIAS have handled numerous advanced, and very interesting, assignments.
We are happy to demonstrate some of these solutions to give an idea of the scope we can offer in terms of advisory services.

The North Sea Museum - a complex solution

When the North Sea Museum in Hirtshals suffered a fire in 2003, one of the subsequent tasks was restoring the huge Oceanarium's windows. RIAS was involved in this major project.

Three of the eleven acrylic panes in the Oceanarium were so damaged that they had to be replaced. The remainder were cleaned and renovated.

The large size of one of the panes (4.8 x 6.1 m and 270 mm thick) was a particular challenge. Eight of the existing panes could be reused, and RIAS was involved in the cleaning and polishing of the acrylic.

Cast acrylic is the obvious material for such large sizes, particularly for aquarium windows, as the pressure from the water is huge. The benefits of acrylic include the fact that it is as clear as glass, weighs very little despite the large dimensions, is easy to clean and maintain and provides a very high degree of unbreakability, as demonstrated by the fire in Hirtshals: Only three of the eleven panes had to be replaced due to damage, which is impressive when you consider the intense temperatures they were exposed to.

The work of installing the large acrylic pane in the Oceanarium is closely monitored by RIAS' technical department.

Vestervig aktivitetscenter (community centre)

In spring 2005, RIAS was involved in a project with Vestervig community centre. More light was needed in the activity hall and this was achieved by producing a large skylight strip.

The material chosen was Riatherm, clear polycarbonate sheets. A total of thirty 16 mm thermal sheets were fitted using section system 2. The vast majority of the sheets were 5390 x 980 mm.

The picture on the left shows the roof from inside the corridor located between an existing and a newly-built hall in the community centre. More light was needed - and this was achieved using Riatherm sheets.

On the right you can see the entrance section with the clear thermal sheets.

The picture below is the front of the building, facing the car park and the road. Skylight strips have been positioned round the corners in the building.

Gigantium, Ålborg

One of Denmark's largest projection screen installations can be found at Gigantium in Ålborg.

Both screens are 4 x 3 m in size, made up of two 2 x 3 m sheets. The material is extruded acrylic sheet, Plexiglas XT RP, grey and 3 mm thick.

Behind each screen are 4 projectors.
