Your proposal for the equivalent term for England?

 

The regs are much the same but the big difference is needing complete submission and  sign-off before commencement. A very good thing in such cases, avoiding false starts 

 

What we are missing is any drawings; so it's impossible to advise on fire requirements.

Hi,

The cement board idea could actually be a good one as it is A1 fire rated therefore non-combustible.

 

 Firegaurd fire suppression coating would not need to be used on the wooden frame or trusses. The total cost of the cement board is almost the same as Firegaurd coating.

 

If I use the cement board to completely line the internal walls and ceiling of the garage. This would create a box of 6mm cement board that would protect the wooden frame and roof trusses from an internal fire and ensure it’s stability in the event of a fire as well as transfer of fire from the inside of my garage to another. It would also not require an unprotected area calculation as part of the design plan submission.

 

if the metal exterior cladding is A1 rated this also will be enough to pass regs. Anything less that this rating will require unprotected area calculations. I’m waiting on the manufacturer of the proposed metal cladding confirming its fire rating specifications.

 

The double skin could also open up the possibility of non flammable insulation between the layers in the gaps in the stud partition walls and above the ceiling making the garage far more usable in the winter.
