Kingspan / Insulated Panel Store - Fire ratings

[jeli]

So, jumped through the planning application and now falling foul of building regulations.

 

In the plans was for a 6.6m x 3.3m garden room, within 1 m of the boundary. This would be using Kingspan quadcore and Coldstore panels. I.e. one of their kits.

 

Kingspan data sheets mention the panels are tested on the internal face and meet b-s1-d0 classification. Kingspan sneakily don't declare the external face rating, so I've reached out on email to ask as per the datasheet recommendation. Unfortunately, over the phone the question could not be answered.

 

Has anyone else been down this rabbit hole before with Kingspan and building regs. 

 

Building regs are advising the materials need to be inherently non combustible which these panels apear are not.

 

Thanks!!

I think we all know how much we can trust Kingspan datasheets. 🔥

Non combustible means A1 fire rated only. Kingspan products as a petrolium based product will not be A1 fire rated no question. Only bricks, blocks, plaster, many mineral wools, steel will be A1. How about a steel shed with mineral wool insulation and plasterboard linings

Rigid rockwool and cement fibre-board, with suitable top, edge and joint detailing?

Or build it from concrete blocks.
