Key facts & Challenges

The Dolphin School is a two form entry primary school for approximately 420 children currently underconstruction in Montpelier Bristol. The new school facility will provide further space to the existing school, with the construction taking place on the site of a former engineering works, within the grounds of the current school. With close neighbouring residential properties and the existing school within feet from the live site, Weather Defence met the necessary requirements for this challenging project.

Installation phase

Weather Defence is an Euroclass A1 Non- Combustible external sheathing board which is the highest classification for reaction to fire, for a building product. Weather Defence being non-combustible reduces the potential for the horizontal spread of fire between adjacent properties, especially on this project where properties are only several feet away from the new building. With technical support from a Siniat Technical Specification Manager, the solution of combining Weather Defence with a Siniat 15mm A2 rated Internal Universal board, BAM achieved a 60 Minute fire rating for the through wall, which met the criteria recommended by the District Fire Officer, to reduce potential horizontal spread of fire.
