Non-combustible upstand board launched

In what it dubs its ‘latest step to help specifiers and contractors mitigate fire risk in the fifth façade’, Rockwool has launched HARDROCK UB34, a non-combustible insulation solution specially designed for parapet walls and upstands on flat roofs.

The stone wool insulation specialist says it has created UB34 to provide a robust, thermally efficient upstand insulation board that is also non-combustible in case of fire. Combining a dense 50 mm slab of Rockwool stone wool insulation, bonded to a rigid 6 mm fibre cement board, the system is impact and weather-resistant.

Rockwool explained: “Thanks to its stone wool core, HARDROCK UB34 has been fully tested and classified as Euroclass A2-s1, d0 – making it suitable for use on buildings over 18 metres high that are affected by the ban on combustible materials.”

UB34 helps specifiers and contractors mitigate fire risk by providing a durable, non-combustible insulation solution compliant with the latest guidance for buildings over 18 metres high,” said Will Wigfield, Product manager – Building Envelope, at Rockwool UK. “A purpose- designed solution, it is easy to install – and its stone wool core provides an excellent thermal performance.”

Compatible with a range of flat roof systems, including single-ply and inverted,

HARDROCK UB34 is manufactured with a Rockwool base slab which has thermal conductivity of 0.034 W/mK, helping to reduce thermal bridging through roof upstands.
