Talk:Sandwich panel

incorrect article
This article appears to be an inaccurate advertisement for certain parties.

Aluminum composite panels were not invented by the claimed reference. Aluminum (composite) honeycomb panels, in their modern-day form, were invented in 1948, by Steele, et al, and were around much longer before that in various other forms (see links), and were certainly already around before the claimed invention date of the article.

 * This article is not, primarily, about honeycomb panels. Those are complex, expensive and high performance, mostly used for aerospace. The panels described here are much simpler, cheaper and used for architecture. Andy Dingley (talk) 12:33, 29 December 2017 (UTC)

time references
"20 years ago" and "40 years ago" are relative terms which, as time goes on, are less and less accurate. This means this document is doomed to failure of inaccuracies, if it is not already. If an unknown date or year of invention is known, then use the decades term, as "in the 1970s" I use wikipedia to find data, not to have to go somewhere else to find the data to fix someone else's mess, as such I won't be fixing this. ~AeSix 96.254.154.61 (talk) 20:31, 6 August 2013 (UTC)
 * This is one of the most common problems with Wikipedia articles. It would probably be a nice feature in the editor to have it filter relative dates and yield a warning message ;-) --BerlinSight (talk) 18:54, 9 August 2013 (UTC)

number of tiles in Spaceship Earth
The picture text says ''Epcot's Spaceship Earth is an example of the use of ACP in architecture. It is a geodesic sphere composed of 11,324 ACP tiles.''

Its article says 11,448, and neither of those have sources marked (at least not directly on that info). Is either of those the right number? 85.76.169.72 (talk) 23:18, 18 September 2015 (UTC)

corrupted references
It appears many references have been corrupted. For example, an older version of the page has a link to coroplast.com which goes to coroplast.com, but in the current (2017/01/29) version goes to "batiplac.com". Indeed, most external reference go to the same one page at batiplac.com. — Preceding unsigned comment added by 50.0.151.153 (talk) 20:17, 29 January 2017 (UTC)
 * Thanks. Seems someone had reverted this likely spam [//en.wikipedia.org/w/index.php?title=Sandwich_panel&diff=next&oldid=757141350] Nil Einne (talk) 06:02, 16 June 2017 (UTC)

Review
These panels are everywhere, in many hidden forms. The many recent changes to this article suggest a review and restructuring may be in order.

Suggest integration or merger of structural insulated panel and/or metal faced insulating sandwich panels, for example. Protozoon (talk) 13:48, 17 June 2017 (UTC)

Precast Concrete Sandwich Panels
This article doesn't mention sandwich panels composites with concrete. An example composite is 80cm concrete, 290 cm insulation Polyurethane and then 80cm concrete. The concrete column at each end of a panel can be load bearing and it also often has a load bearing beam running across it. — Preceding unsigned comment added by B0ef (talk • contribs) 08:08, 11 October 2019 (UTC)
