>Here is a further update on the fire at Whyalla. Lance Kairl is a straw
>bale builder based in South Australia and has done some great straw bale
>If any of you have some ideas please let Lance know:
>Lance is on: sabale@...
> My two bobs worth would have been to have left the render alone and
>not touch it after the fire but to have cooled the external render down
>with water. However having not been there I do not know how much damage
>was done to the render before the fire services got there. As the New
>Mexico fire test showed the charred portion of the bales acted as a
>barrier/sealer to the rest of the fire penetraing further into the bales
> ie a 2" wall of charcoal.
>So if the walls could have been cooled down before any render was broken
>off then........?? Always 20 20 vision in hindsight. As for the repair
>Water damage; Whyalla has little or no rain so the bales should dry out
>in time and the hot weather we have had should speed that up. So I
>would wait a while before any one agrees to the Insurance mob's request
>to replace all water damaged bales. Again I am not on the scene so I
>can only summise.
>As for repairing the smoke damaged render well I do not know but surely
>we could use something a little more friendly such as a breathable
>substance such as Grimes's water repellant? The areas that need re
>rendering well here I would go with an earthen render but then we would
>have to match the rest of the building which has a great colour to it
>from the original render.
>Anyhow to those that responded to the first news about this attempt to
>burn down the Buddhist SB here is a first hand report. IMHO SB has won
>out here as any other building would have surely burnt to the ground.
>However I am pretty one eyed about these things as you all well know.

> 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.
>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
> the wet straw may Spontaniously Combust, in a day, week, month.
> 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
> low tec solution to this problem?
> If you have any pearls of wisdom out there feel free to suggest them.
