Sika Sarnafil waterproof roofing membrane was specified for a £8.8 million new build school in Llandudno Junction, North Wales.
The new Primary School, is set to replace two older primary schools as part of the 21st Century Schools Initiative. The modern design includes spacious classrooms, nursery facilities, playing fields and community space, to accommodate an increased capacity of 420 pupils.
Designed by Ainsley Gommon Architects, the newly established community primary school also needed to blend into its rural surroundings, it was also important that the school building was built with a range of sustainability strategies, such as the use of sustainable materials and installation of green roofing and solar panels.
Due to its location on a greenfield development that rises steeply to the south east, with much of the flat land set aside for the sports field and games area, the main school buildings had to be accommodated on a slope.
Ainsley Gommon Architects devised a split level solution, with a large curved teaching wing following the natural contours of the site. This was then linked via a corridor to a ‘Community Hub’ that includes the main hall, offices and meeting rooms.
An adhered Sika Sarnafil waterproofing membrane was chosen – G410-15ELF Lead Grey – thanks to its ability to emulate the standing seams on a metal roof with Décor Profiles, creating the same aesthetic appeal.
The curved, pitched roof was a challenging installation, but AAC Waterproofing Ltd were up to the job, supported throughout the process by the Sika Sarnafil Technical Team.
The architect chose a 900m2 sedum and wildflower roof which was loose laid with Sika Sarnafil root resistant membrane.
The building is targeting a BREEAM Excellent rating, due to its fantastic sustainability credentials, including natural ventilation, harnessing passive solar gain, photovoltaic panels, and the thermal performance of the roof build up with its A+ rated Sarnafil membrane.
