			<![CDATA[Greetings All!<br /><br />Just found this forum -I'm normally too busy to spend too much time on th'interwebnet.  Am slighty obsessively fascinated by eco & green stuff in building. I'm an Air Test Engineer and happy to share knowledge. <br /><br />Cheers <img src="/newforum/extensions/Vanillacons/smilies/standard/bigsmile.gif" alt=":bigsmile:" title=":bigsmile:" />]]>

			<![CDATA[Sorry Peeps, I've been awfy busy :-/   replies in order...<br /><br />DarylP, I'm used to covering the UK and channel islands, I'll go where I'm paid to but I'm based in east Anglia.<br /><br />JamesIngram, I'm BPEC certified as a "competent Person" to test, balance and theoretically install MVHR but to get it put in, you'd do better to speak to the big boys in that particular business as that's not something I've done...yet...<br /><br />Gotanewlife, if you knew me you'd know how redundant that question is<img src="/newforum/extensions/Vanillacons/smilies/standard/shamed.gif" alt=":shamed:" title=":shamed:" /> lol<br /><br />Andrew Hugman, worst score for a New Dwelling is about 27.3 as I recall, worst quantifiable score for a commercial was 32!! (even better, this was a building Factors, specialising in roofing airtightness products!!!)  Worst for an existing dwelling test was 19.6 reduced to 5.9 on next visit after advice.  It's very rare for advice to actually be followed, so I was super-proud of that one <img src="/newforum/extensions/Vanillacons/smilies/standard/bigsmile.gif" alt=":bigsmile:" title=":bigsmile:" /><br /><br />My humble apologies all, for taking so long.  I'm going to set GF as one of my home tabs now so I don't forget I'm on here!]]>

			<![CDATA[Hi bot de paille, I've never felt anything coming through the surface of OSB even at -100Pa decompression, the problem usually lies with the joins, junctions, angles and edges, as it does with any sheet material without a membrane behind it.  If I were feeling paranoid about future performance, I'd slap a coat of PVA on it!]]>
