Redlands Rosemary Plain Tiles in Classic Red have been installed as part of a new £3.6 million tiger enclosure at ZSL London Zoo.
The enclosure, which will house critically-endangered Sumatran Tigers, includes both outdoor and indoor accommodation for the animals; with the indoor being a refurbishment of what was originally a stork and ostrich house. The aviary was originally built in 1897 and needed retiling as part of the building work done to bring it back into use as part of Tiger Territory.
Architect Michael Kozdon, of Wharmby Kozdon Architects, commissioned the Rosemary Plain Tiles in Classic Red because of their aesthetic suitability for the refurbishment of the roof: The original tiles were natural clay and Redland had the nearest match to this. I have specified Redland tiles before for other projects and in this case they really suited the conditions of the roof.
With the roof pitched at 35°, Rosemary Plain Tiles were ideal for the job as they are suitable for use from a minimum roof pitch of 35°.
Rosemary Plain Tiles are often commissioned for refurbishment because the range of colours available mean they fit with many types of vernacular.
The project involved a traditional style of fixing with mortar. Arris hip tiles were also specified. Arris hip tiles, available in all Rosemary Classic plain tile colours and usable from a roof pitch of 35°, were an ideal accompaniment. Tile-and-a-halves were used to maintain bond and provide a neat cut finish.
Jerry Sullivan, Managing Director of Allard Construction, who installed the roof, said: I feel Redland have always offered a quality product; in my 30 plus years working with pitched roofing products I have always noted Redland as a premium brand. The technical support offered by Redland staff gives me peace of mind and ensures my clients confidence in the product.
The whole roof has been designed and engineered to withstand 50 year event weather conditions. Rosemary Plain Tiles have the advantage of being extremely resistant to the freeze thaw process and meet all the requirements of BS 5534: 2003, the code of practice for slating and tiling. The installed roof tiles for this project, including the junctions between them, are guaranteed for weather- tightness for fifteen years after their installation under the terms of the Redland Guarantee.
The 2,500sqm tiger enclosure will be open for the public in spring 2013.
