			<![CDATA[I know that when I started building I was looking for insulated door blanks but it all proved too difficult so I went for expensive pre-made doors. And I know there have been various threads on here about making insulated doors. So I thought it worth while pointing out that I've just seen an ad in Passive House Plus for PHI-certified door blanks. I hope it's alright to post a link <a href="http://www.moralt-ag.co.uk/ferro-passiv.html" target="_self" rel="nofollow">http://www.moralt-ag.co.uk/ferro-passiv.html</a>  They're available in the UK from James Latham. I have no connection with either firm, just thought it was something worth making people aware of. Neither have I any idea of the prices.]]>

			<![CDATA[Invaluable intel - great. It's got to be OK to tell about finds like this.<br /><br />Bit mystifying.<br />2490 x 1150 x 98thk, can be trimmed by 10mm to all edges.<br />Then it says 'When trimmed by a maximum at the bottom (120 mm) ...'<br /><br />'Minimum distance for glass apertures on all 4 sides: 180 mm' - no info on how to finish the cut edge.]]>

			<![CDATA[The allowable trimming does seem a bit awry, and whilst they make a lot of the sales pitch stuff, if you dissect the construction, its an engineered timber frame with a solid insulation foam core and plywood exterior, and a bit of metal. All of that is within the capabilities of any laminating company with a press.<br />The bottom rail too does seem light @ 70mm, -- or maybe I've read the wrong thing? <br />I guess it's the certification that gives them the edge, but pure construction wise it' doesn't seem anything special.]]>

So to my mind the main difference is between available product and the possible capabilities of somebody who I may or may not be able to find (and didn't).]]>
