Marley Eternit has brought several decades and millions of square metres of expertise in supplying fibre cement tunnel linings to an enhancement of their popular Glasal cladding panel.
Glasal T is an improvement to the standard autoclaved panel already used in underpasses and tunnels such as the Limehouse Link in London and in Belgium, China, South America and Malaysia. It has been in development for 18 months and successfully tested in the re-lining of the Mont Blanc tunnel.
Original 7.5mm Glasal was so well suited to the particularly onerous task of lining tunnels, with their corrosive atmospheres and the increasing demands of cleaning, that further enhancement has been simple.
The Glasal T panel has an extra protective coating in addition to the double mineral paint layer already applied, to make it completely impermeable to the atmospheric conditions that necessitate frequent mechanical cleaning of the 1,220mm-wide panels.
Lightweight with a semi-matt mineral enamel finish, Glasal panels are colourfast and easily meet the current European (EN 13501-1 A2-s1-d) and British Standards (Class 0) with regard to the limit of flame spread.
Optically flat, Glasal panels allow perfect diffusion of light and eliminate glare and dazzle which could be dangerous to drivers. Available in a range of mineral-enamelled colours, they typically reflect up to 87% of light rays, reducing the operator’s reliance on artificial light.
