Promat PROMATECT-B reinforced calcium silicate board was used in many partly-exposed areas of the stadium. The lack of inorganic fibres and a water repellent silicone treatment to both faces make this Class 0, fibre-reinforced, medium density calcium silicate fire board ideal for this purpose.
A combination of 9mm thick Promat SUPALUX and 9mm thick Promat PROMATECT-HD was also used to create the most suitable fire protection solution for other areas of the stadium, such as semi-exposed wall linings which might be subject to both direct rain and impact damage. Promat PROMATECT-HD is a dense compressed building board manufactured from an autoclaved mixture of Portland cement, organic fibres and selected mineral fillers. The resulting board has high dimensional stability and considerable strength.
“This is a very complex building with lots of semi exposed locations,” says Peter Keenan, Promat Business Manager for Ireland. “As it was a rebuild project there were also numerous space limitations, and so being able to accommodate these by sourcing a variety of different fire protection products from a single specialist manufacturer was a significant advantage.“
The project saw the rebuilding of the famous Lansdowne Road Stadium – one of the oldest international rugby stadiums in the world – to create a modern new facility that can seat an audience of over 50,000 people.
The project architects were Scott Tallon Walker of Dublin. The main contractor was John Sisk and the sub contractor was Errigal Contracts, also of Dublin.
