Revealed: a widely used kind of combustible cladding has never passed a large-scale test #ukhousing

High pressure laminate (HPL) cladding, which is not made of aluminium and was not used on Grenfell Tower, is made from combustible materials.

The government’s official guidance, on one interpretation which the government has supported, says combustible cladding must be subject to a large-scale test, or a British Standard (BS) 8414 test, before being used.

HPL cladding is found on tower blocks around the country, and yet a spokesperson for the Building Research Establishment, the only place in the UK that conducts BS 8414 tests, said: “None of the cladding systems that have passed a BS 8414 test include a high pressure laminate.”

A system using HPL cladding has failed at least one BS 8414 test, as insulation company Kingspan has revealed. The firm has posted a series of test reports online, including one from a failed test of its K15 insulation combined with Trespa’s HPL rainscreen board, conducted in 2002.

Some in the cladding industry have argued that the government’s interpretation of its official guidance is inaccurate, saying it advises that combustible materials can be used in cladding, as long as they have a Class 0 surface spread of flame, which some HPL products achieve.

A spokesperson for the Ministry of Housing, Communities and Local Government, when asked about this, directed Inside Housing to an advice note on the government’s website.

This reads: “It is important that the right combination of products has been installed and maintained correctly, to ensure they adequately resist the spread of fire over the wall to the standard required by current building regulations guidance.”

Arnold Tarling, a chartered surveyor at Hindwoods, told Inside Housing: “I’ve been saying, we’re only talking about ACM cladding, not about all the other cladding.

“I could take you to five properties straight off and that’s just in Southwark and Lewisham. It’s pretty daft. The thing with high pressure laminate is, they make these fancy patterns, but how do you get fire breaks in? They often don’t have straight lines, they have curvy, wavy lines.

“They’ve got a fire risk, [even though] it won’t spread as quickly as polyethylene does.”

Never Again campaign

Never Again campaign

In the days following the Grenfell Tower fire on 14 June 2017, Inside Housing launched the Never Again campaign to call for immediate action to implement the learning from the Lakanal House fire, and a commitment to act – without delay – on learning from the Grenfell Tower tragedy as it becomes available.

One year on, we have extended the campaign asks in the light of information that has emerged since.

Here are our updated asks:

GOVERNMENT

  • Act on the recommendations from Dame Judith Hackitt’s review of building regulations to tower blocks of 18m and higher. Commit to producing a timetable for implementation by autumn 2018, setting out how recommendations that don’t require legislative change can be taken forward without delay
  • Follow through on commitments to fully ban combustible materials on high-rise buildings
  • Unequivocally ban desktop studies
  • Review recommendations and advice given to ministers after the Lakanal House fire and implement necessary changes
  • Publish details of all tower blocks with dangerous cladding, insulation and/or external panels and commit to a timeline for remedial works. Provide necessary guidance to landlords to ensure that removal work can begin on all affected private and social residential blocks by the end of 2018. Complete quarterly follow-up checks to ensure that remedial work is completed to the required standard. Checks should not cease until all work is completed.
  • Stand by the prime minister’s commitment to fully fund the removal of dangerous cladding
  • Fund the retrofitting of sprinkler systems in all tower blocks across the UK (except where there are specific structural reasons not to do so)
  • Explore options for requiring remedial works on affected private sector residential tower blocks

LOCAL GOVERNMENT

  • Take immediate action to identify privately owned residential tower blocks so that cladding and external panels can be checked

LANDLORDS

  • Publish details of the combinations of insulations and cladding materials for all high rise blocks
  • Commit to ensuring that removal work begins on all blocks with dangerous materials by the end of 2018 upon receipt of guidance from government
  • Publish current fire risk assessments for all high rise blocks (the Information Commissioner has required councils to publish and recommended that housing associations should do the same). Work with peers to share learning from assessments and improve and clarify the risk assessment model.
  • Commit to renewing assessments annually and after major repair or cladding work is carried out. Ensure assessments consider the external features of blocks. Always use an appropriate, qualified expert to conduct assessments.
  • Review and update evacuation policies and ‘stay put’ advice in the light of risk assessments, and communicate clearly to residents
  • Adopt Dame Judith Hackitt’s recommended approach for listening to and addressing tenants’ concerns, with immediate effect

CURRENT SIGNATORIES:

  • Chartered Institute of Housing
  • G15
  • National Federation of ALMOs
  • National Housing Federation
  • Placeshapers
