>  John , have posted this message to a Stawbale users Group,
>  The extent of (lack of )damage to the building has NOT impressed some, and

>has ( impressed ) others. In This instance there was more dammage done by WATER/

>Fire Services than by fire.
> Perhaps we need to devise an efective technique for extingurishing smoldering

>within a bale wall?

> Arson attack on the Strawbale Budhist Temple at Whyalla on Tuesday 7/3/00.

> A stack of jarrah flooring provided a large ammount of fuel,
> The resulting heat generated from this ment that fire tranfered thru the render

>into the wall cavity.
> As The fire test info states the direction of travel was along Joins in bales

>and up and down the joins.Some damage to render on the top of the bale wall

>when fixing roof sheets may have created a chimney effect within the wall.
Air
>getting in from 
> fine cracks in render, at wall floor junction and window  / door junctions

>fueled the smoldering within the wall.
>
>Most air entering the wall was obviously from under the timber 
> bottom plate , as smoldering burnt DOWN ( yes Down as well as up  in the wall)

>much to amazement of Fire Services. In two places top timbers of bottom plate

>was burnt thru , dinner plate size holes.

> Insurance Loss Adjuster was concerned about the ammount of water poured into

>the wall , and his enquiries suggested that

> Not an risk they ( THe insurer ) wanted to take however small.

> the Decission; remove all of the damaged / wet SBwall and rebuild. Wall section

>involved 6ml x 4mh .

> The questions I have are to do with;
>      There has been masive smoke dammage, staining inside and 
>   outside render, Loss Adjuster wants to paint a Stop Stain Sealer on walls

>, then possiably re-render with thin colour coat.
>   The Temple was built on an Eco City site , with a high earth friendly bias.

>
> Is there a Earth friendly stop stain product?
> If so is it Breathable, as both int. / ext . need to be done?
> Are any of the Chemical sealers Breathable?
>
> A good OLD tradesman ( plasterer) suggested a mix of 1:1
> fresh green cow manure and cement as a wash on wall just prior
> to re- rendering, I believe it works , is there any confirmation of this out

>There, as its not me who needs convincing?
>
> The other Question relates to creating an expansion joint
> where the new and old renders will meet when we replace the 
> dammaged wall section; Again Loss Adjuster is going for the Technical Fix
,
>a two pack  product, can any one suggest a good

> If you have any pearls of wisdom out there feel free to suggest them.
