Novum Structures, a globally recognised specialist marine contractor in glass, steel and ETFE, has worked with Pyroguard to design a fire-rated, clear-view façade glazing system that is fully tested and accredited to meet A30 and A60 fire resistance criteria for use on cruise liners.

The innovative solution was developed for the Royal Caribbean Group and first used as part of its latest ‘Wonder of the Seas’ liner.

Pyroguard’s glazing system had to deliver exceptional fire resistance while maintaining a clear-view façade glazing system without obstructing frame elements.

A key engineering challenge was the curved configuration of the glazing system. Traditional curtain wall systems would have required extensive use of steel supports, significantly increasing the overall weight and obstructing passenger vision.

To address the design and weight challenges of the project, Pyroguard proposed the use of a butt-jointed glazing system. This provided a structurally efficient and lightweight solution that offers the necessary flexibility.

This approach also enhances visual clarity, light transmission and UV stability without compromising safety.

Pyroguard’s toughened fire-rated glass is designed to withstand fire exposure for up to 60 minutes. The installation consists of 280m² of 32mm thick glass comprising three layers of toughened safety glass with two active gel interlayers. The internal cavities of the profiles are filled with non-combustible insulating materials to minimise heat transfer, resist high temperatures and provide excellent insulation, effectively preventing the spread of flames, smoke and heat.

The glazing system is supported by a robust stainless steel profile structure, made from 1.4401 grade steel, which was selected for its superior corrosion resistance in marine environments.
