Radomes and lighthouses similar to those shown below have been constructed with both polyurethane and expanded PVC foam cores.
Radomes
Radomes manufactured by RGE Pty Ltd are currently in operation on Mt Barrow and Mt Wellington in Hobart. These radomes have been subjected to severe weather conditions for up to 20 years in some cases, with no adverse effects. These panels are required to withstand huge wind loadings, often in excess of 150km per hour, and extremes in temperature. The largest radome built to date is 8 metres in diameter.
"....The harsh nature of the Mt Wellington site and its environment, combined with the unique engineering solutions developed for both the design and construction of the tower surely elevated the project to a high level from the start. However, I believe the design approach, quality assurance methods and high achievements in fabrication and construction in often difficult and trying circumstances certainly enhanced its status. The radome is clearly a significant part of the tower. The design, fabrication and construction of the radome would not have been the success it is without the team spirit participation of RGE. I would like to thank you and your staff for the unerring assistance, through all phases from concept to construction, in achieving the most practical solution and a consistently high quality product...."
