FRP PET foam sandwich panels.

key features

Composites elements: 14 decorative ceiling cowlings, measuring 2 x 12m each, with an innovative metal-effect coating, comprising 192 composite internal panels designed to be fixed to the main trusses of the roof structure.

Why composites: composites allowed the installation of large decorative elements that could be suspended from the existing roof structure.

Weight

FRP provided the appearance of metal without the associated weight and cost.

Cost

Producing these elements from metal would have necessitated roof structure reinforcement, significantly increasing project costs.

Strength

The parts are decorative and not under any external load, but producing double curvature composite parts of 26m x 12m in size require them to be as light as possible, whilst also being self-supporting.

Durability

The parts were designed to withstand environmental conditions and were robust enough to prevent damage during transport.

Maintenance

No maintenance is required for the composite parts. Metal alternatives would have required regular inspections to check for degradation.

LCA/Environmental Impact

Using traditional materials would have required additional support, regulation, installation equipment, and maintenance. This composite solution was less challenging and had a reduced environmental impact.
Fire, Smoke, Toxicity : this was the first example of sculpted chrome-finished panels that are fire-resistant to BS 476 Part 7 Class 2.
