Straw as part of wall

[Guest David]

Hi 

Can someone please give me advise on the picture attached. This is the construction of a flat wall in a small purpose built block of flats. This is like straw construction with a skim over the top. The flats are on a stay put policy and I’m pretty sure there needs to be 60 minutes compartmentation for a stay put in flats. Will these wall last for 60mins, or are they dangerous? Any information welcome

Doesn't look convincing.....

It is called Stramit Board and was used about 40 years ago search the web for more info.

Thanks Tom!

Never seen it before - you should get 30 minutes Fire Resistance from a intact panel according to the manufacturers..

David needs to check out where it is being used also what is the the fire resistance of the construction between each flat and the common areas.

Which walls are constructed with stramit, is it the inernal walls or the external walls of the flat and does any any walls expose the straw.
