Upstand Board
| BEWI Upstand Boards are designed to deliver thermal insulation for upstands in flat roof constructions, commonly used in inverted roof systems. Their primary role is to insulate parapet upstands and minimise cold bridging, helping to maintain the thermal integrity of the building’s internal envelope.
Manufactured from mineral wool insulation, factory-bonded to an external-grade, high-impact fibre-cement facing board, BEWI Upstand Boards ensure durability. They are engineered to provide a robust, weather-resistant, and impact-resistant finish. |
Key Benefits

Application Fields
BEWI Upstand Boards provide a non-combustible, impact and weather resistant thermal insulation for use on low level inverted roof parapet upstands, including to and across compartment walls.
Low level installation to meet standard thermal break requirements is 150mm above the finished roof level or 300mm above the bottom surface of the inverted roof insulation. Should the roof designer specify installation beyond standard thermal break requirements the board height should not exceed 1100mm.
The application of this product should always be confirmed by the Building Control Authority responsible for the project.
