A few test programs run i 2004 at acknogledged institutions, where straw walls were tested for fire - only a 30 minute test, insulation properties and mould growth, lead to a small publication with some guidelines on how to do a "safe" SB wall, has opened all doors since. <br> <br>Regarding fire in Poland and certification, I wonder, if it is a certified BALE you need, or a fire test of a wall assembly? The bale in it self is obviously not giving fire resistance, but the section with render is. Here in Denmark, 30 mm of clay or lime render, gives you a 30 min fire - accept, only because that was the only test the SB organisation could afford at the national institute for fire testing. That can give us similar complications on larger/public buildings were higher degrees of fire safety is required., as the Polish face.</div> <div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)">And then how is it..<br>We all follow the same engineering codes (<span class="" style="">EuroCode</span>), but we have national building codes (regulations). If a fire test of 60 or 90 minutes was carried out in one European country or in a collaboration between several countries, would it not benefit all European countries?

But in situ construction does not require certification of each material. BUT yes indeed, I can face the same problem with carpenters and contractors, who are not always willing to take the responsibility of using non-certified materials, and that can be straw bales as well as under roofing etc. - But that is not because of an official requirement, that is because they end up with a responisbility that some feel insecure about. - And thus I only work with those who have the common sense to see that this works if they do it well.</div> <div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)"><br>I agree Herbert, it is very important to go down the road as the French, rather then going for a certified bale - VERY IMPORTANT :))</div> <div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)">Cheers</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(103,78,167)"> Caroline</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/3/5 asbn <span dir="ltr"><<a href="mailto:asbn@baubiologie.at" target="_blank">asbn@baubiologie.at</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div style="word-wrap:break-word">Hi to all balers outside<div><br></div><div>A great THANK YOU for your answers, it helps a lot!</div><div><br></div><div>As I thought (and feared), the certification in a country</div><div> * gives safety to carpenters (if they use these certified bales) and helps them with their responsibility.</div><div>* but seems to start a parallel process, that uncertified bales will be forbidden with the argument, </div> <div> that there are certified bales available on the market (even when they are not available).</div><div><br></div><div>In Austria we have a situation now, where only skilled builders (and that means with a special education and qualification)</div> <div>are allowed to take responsibility for a building, and even if I want my own responsibility,</div><div>I cannot take it as a self-builder without these special qualifications, even for a small experimental building.</div> <div>This situation stops innovation, as only prooven and tested techniques (and materials) are allowed.</div><div><br></div><div><div>I agree, that this supports "industry" and bigger companies, which are able to afford tests and certification processes.</div> </div><div>And in long terms it stops all self-builders from building on the basis of experience, long known knowledge and tradition.</div><div><br></div><div>I personally think therefore, that establishing a national building code - like in France - is the much better way as a certification process.</div> <div>Although I know, that it is much more work and needs much more effort than a (simple) test and quality management.</div><div><br></div><div>And my personal recommendation: If you think about a certification in your country, nevertheless (which is not my first choice), </div> <div>do it like FASBA in Germany or (with restriction) the GrAT in Austria do,</div><div>try to find a non-profit organisation, which makes a mobile certification on bales of your choice, independently from the season of the year,</div> <div>otherwise you always depend on the amounts of certified straw bales, a company has stored.</div><div><br></div><div><div> <span style="text-indent:0px;letter-spacing:normal;font-variant:normal;text-align:-webkit-auto;font-style:normal;font-weight:normal;line-height:normal;border-collapse:separate;text-transform:none;font-size:medium;white-space:normal;font-family:Verdana;word-spacing:0px"><div style="word-wrap:break-word"> <div><div>yours sincerely</div><div>Herbert</div><div class="im"><div>-----------------</div><div>asbn - austrian strawbale network</div><div>3720 Ravelsbach, Baierdorf 6</div><div>Tel. 02958-83640</div><div><a href="mailto:asbn@baubiologie.at" target="_blank">asbn@baubiologie.at</a></div> <div><a href="http://www.baubiologie.at" target="_blank">www.baubiologie.at</a></div></div></div><div><br></div></div></span></div></div></div><br>____________________________________________________<br> European strawbale building discussion list<br> <br> Send all messages to:<br> <a href="mailto:Strawbale@amper.ped.muni.cz">Strawbale@amper.ped.muni.cz</a><br> <br> Archives, subscription options, etc:<br> <a href="http://amper.ped.muni.cz/mailman/listinfo/strawbale" target="_blank">http://amper.ped.muni.cz/mailman/listinfo/strawbale</a><br> ____________________________________________________<br> <br> <br> <br></blockquote></div><br><br clear="all"><div><br></div>-- <br><div>Caroline, Tahir, Noah</div><div><br></div>Friland 11, 8410 Rřnde, Denmark, tlf.
