[GSBN] Fire resistance test of an uncladded/ unplasted straw insulated wall (infill): Need informations

[Dirk Scharmer]

Hi,
FASBA is planning to do a 30 minutes fire resistance test (according to 
DIN EN 1365-1 and DIN EN 1363-1) of an unplastered straw insulated wall 
on october, 25th at MPA/ University of Braunschweig. I remember that 
there should have been one in Denmark in the past, is that correct? Or 
somewhere else in the world? We're hoping to reach REI30 without 
cladding.

Please help us with mailing details and test reports about fire tests of 
straw insulated walls which have been conducted without cladding 
anywhere in the world.
As we always did, we'll publish the test results.

We already conducted three fire resistance tests. One also with 8mm clay 
plaster which was 52min successful, but with that test we're determined 
to clay on the outside, and a certain manufacturer of clay...

The reason for the new test is, that we want to avoid discussions with 
authorities about the type of plaster, because they're insisting that 
we've to use only the already tested one (exactly!). Don't worry, we 
don't want to do uncladded straw walls, it's mainly for being to have 
lime plastered wall in REI30. REI30 is what we need for up to 3-storey 
buildings.
Currently we're building a 5-storey office building with straw insulated 
walls in Verden/ Aller in the near of Bremen. Therefore we ran tests 
with 5-7cm special clay and lime plaster. In the trailer for the new 
straw building film of Heidi Snel you can see pictures from that 
building beneath other projects:

Thank you!
