Whitepaper

In a new whitepaper, ROCKWOOL examines all the key factors which are contributing to fire risk in flat roofs and addresses how specifiers and roofing contractors can help to mitigate these.

‘Flat Roofs: Managing Fire Risk in the Fifth Façade’ will help you to understand: 

  • Fifth façade and fire risk
  • The real cost of roof fires
  • Roofs and regulations

Fifth façade and fire risk

The roof is one of the most vulnerable parts of the building envelope when it comes to fire risk. The whitepaper explores some of the most common causes of roof fires, including:

  • Arson
  • Hot works
  • Fire spread
  • Plant failure
  • Lanterns / fireworks

The real cost of roof fires

While Approved Document B of the building regulations sets minimum performance standards to ensure the safe passage of exit for building occupants, it does not provide any design guidance on how to protect the integrity of the building. Where fire takes hold within a building and can be contained, damage to the property and contents can often be minimised. This is not the case when fire spreads to the roof. Using high profile case studies, the whitepaper delivers insights into the wider socio-economic impact of roof fires and offers guidance on how these can be prevented.

Roofs and regulations

Introduced to Approved Document B in 2019, BROOF (t4), is the recognised fire classification which assesses spread of fire but is not a measure of combustibility. This has led to some industry confusion in relation to achieving regulation compliance in flat roofs – particularly where non-combustible insulation should be used as part of fire compartmentation in the building spaces below.

Going into technical detail, the whitepaper provides expert advice on how to navigate regulation compliance and shares best practice guidance on futureproofing building performance.
