[SystemSafety] Reynobond panelling

[Dominey, Alan (UK)]

Why do you think that Reynobond FR was utilised (as opposed to Reynobond PE).

Viewing the footage of the fire I would have thought it highly likely that the panels were the base range PE version as opposed to the "more expensive" fire retardant option . . .

There seems to be increasing concern about aluminium composite cladding as building material, e.g., https://www.theguardian.com/uk-news/2017/jun/22/tower-block-cladding-posing-danger-to-thousands-of-residents
. Obviously it is a major concern in the wake of the Grenfell Tower fire.

Many of the initial press articles were indirectly hinting that the panelling was the "cheap stuff", for example that polyethelene-core panelling was used instead of the mineral-wool-core version to save less than £5,000. It would be well to dispel this impression - I think it is mistaken.

Reynobond panelling is produced by a major company, Alcoa, and used throughout the world on large buildings. Reynobond is a registered trade mark in the US of Alcoa. Here is the marketing brochure:
https://www.arconic.com/aap/north_america/catalog/pdf/brochures/Reynobond_Brochure.pdf . It gives some specs, and illustrates six different attachment methods.

A key point is the way the panels are used, in particular the attachment. There is a short description here: https://www.arconic.com/aap/north_america/catalog/pdf/brochures/reynobond_fr.pdf
Note in particular 1.03A: "Shop drawings shall show panel system including attachment methods, joinery, sealing methods and accommodation of thermal movement. Details shall not be drawn less than one-half size."

Details of how to go about installing the panels are given in
