Grenfell Tower block disaster

Someone posted earlier in this thread that the more expensive, less flammable cladding had been rejected in favour of the less expensive, more flammable one. The more expensive one costing a whole £2 a metre more than the cheaper one that was chosen. I wonder who went for the cheaper option, the contactor or the owners.
However if the building passed fire regulations apart from penny pinching had either one done anything wrong?

After completion the building was passed as safe?

There were obviously concerns by the reports earlier in the thread so it'd be a government legislation issue?

In the scenario you paint, blame has to ultimately rest with the legislators.
 
Is that a fact?

Or just something thats now been repeated so often it seems like a fact?

For a few years, I was on the board of a community housing trust which also undertook a major refurbishment programme. Improving the appearence of buildings was definitely an objective of the programme, although by no means the main one. The accepted view was that improving the appearence of the buildings would make them more appealing to residents and potential residents, increase occupancy rates, reduce vandalism etc. There weren't any wealthy properties near our flats and houses so obviously I can't comment on whether that had a disproportionate influence on the Grenfell Tower refurbishment.

There cannot be anything intrinsically wrong with wanting any property to look more appealing from the outside.
 
The building regulations state that for any building over 18m (about 6 floors) the fire resistant cladding must be used on the whole building.

It quite clearly wasn't used in this case, just a matter of finding out if it the wrong cladding was ordered by mistake or if it was a deliberate act to save money.

My cousin is in the cladding game and I was amazed when he told me the regs. I would've thought any building used by humans, let alone residential buildings, would need fire resistant materials no matter what the height

I may sound stupid here but surely someone has to ask why there is a choice in the first place?

Why is there a more flammable option?

Despite being more flammable, does it meet the regulations? If so and the cladding is at fault then the issue is with the regulations rather than the contractor surely?

Well that would change things quite dramatically.

I think the one used is banned in Germany and America on buildings over 3 floors.

I would have thought the less flammable one would be used on factories, warehouses etc. I.e building with good emergency exit, sprinkler systems etc and it be unlikely to have sleeping upstairs

To sum up - I'd suggest that there is nothing wrong with a less flammable one if on an appropriate sized building

That said, this is all assumption, I know nothing about cladding or building regulations.
 
There's all sorts of speculative nonsense around. One I can't get my head round is that an air gap acted as a funnel. If the cladding is primarily for insulation, how can a gap between wall and cladding open to the air do anything for insulation?

EDIT: see below for the answer.

Ventilation is needed in buildings - we need air for gas boilers for combustion purposes, to remove moisture from bathrooms etc.

We don't want to restrict the amount of air going in too much - some is needed. Where the air gap becomes a problem is when there is not stop gap between the floors, the air can travel up the building and act as a chimney/funnel.
 
If a local planning authority gets an application to use cladding on a new or refurbished building, it would normally be up to building regs to say what's legally permissible (how it looks would be a planning issue). I expect they would now turn it down unless non-flammable was specified and one thing central government could do immediately is say it's a material planning consideration (material as in one that matters not a consideration of materials).

Pretty sure that's a building control issue rather than planning, although they do go hand in hand tbf.

If there's an enclosed void it can aid insulation (cavity wall, double or even secondary glazing). If it's not enclosed, how can it possibly help insulation?

See my earlier post - any building above 18m must be clad in non-flammable cladding. This one was not.

The investigation will show where it's gone wrong.

What underpins all this is the council signing it off as okay - what checks were made by the council to ensure the non-flammable product was used on this building which is over 18m?

Were the council tricked into believing the non-flammable product had been used when it had not?

I am assuming that to look at the non-flammable and the flammable product look the same?

It will all come out in the wash

The RATE of airloss will be lowered using the cladding, not removed completely. If you reduce the amount of air loss you reduce the amount of energy you need to heat that air inside the property
 
Firstly, what a horrendous accident.Truly awful.

This tragedy is a game changer for the current fire regulations.

As our modern day society evolves we learn and adapt as we go along.Unfortunately, almost every generation witnesses an incident on a major scale and we all rightly demand answers.
We have all seen that over the last 5 years or so , external cladding of both new and old buildings has become more and more common and i'm afraid this is very much another " state of the art" moment for the construction industry. Multi coloured cladding systems are everywhere, look around.
Let us also get this straight right now , cladding a building in Alucobond panelling is by no means a cheap option.
On the contrary, it is a bloody expensive way of redressing the external fascade of a structure.

The report which has been actioned will highlight all the mistakes and very hard lessons will be learnt by all.
The fire service were there in 6 minutes but it seems they could not get close enough to the source of the fire to prevent its rapid spread. I believe this will be a significant focus of the enquiry . Did the fire get of control too quickly or were the service ill equipped or hampered in their attempts to contain the spread. It will all come out.

The biggest issue now for the construction industry to debate is whether its attempts to refurbish 1960's and 70's concrete structures is the way forward. They are an eyesore on the landscape and the logic behind redressing them is sound in my opinion. The means of escape for the buildings did work , they did there job.

Putting a new skin on the building would appear to have caused this sickening tragedy.
