			<![CDATA[Due to a manufacturing size error I have a spare brand new window. It's good-quality 3G engineered timber from Greensteps, but it's also triangular so unlikely to conveniently fit in most projects.<br /><br />I hope someone can use this for something as it's way too nice to just throw away. GBF gets first refusal.<br /><br />It's in Cambridge.<br /><br />Dimensions:<br />2470mm bottom edge, 1090 LHS, 155 RHS, and 2644 top diagonal.<br />3G 40mm unit: 4(SC)-14A(T)-4FT-14A(T)-4(SC) 0.7W/m2k<br />Fixed light.<br />80mm timber surround, RAL1015 outside, 1013 inside (both approx 'cream')<br />Aluminium rain protection strip on bottom edge.<br /><br />This is actually the correct replacement, but gives you right idea. (this one is 1245mm tall - i.e 150mm taller than the duff one)<br /><a href="http://wookware.org/pics/house/extension/html/472-IMG_4314.JPG.html" target="_self" rel="nofollow">http://wookware.org/pics/house/extension/html/472-IMG_4314.JPG.html</a><br />And this is it fitted, square on: <br /><a href="http://wookware.org/pics/house/extension/html/474-IMG_4316.JPG.html" target="_self" rel="nofollow">http://wookware.org/pics/house/extension/html/474-IMG_4316.JPG.html</a><br /><br />email wookey@wookware.org]]>

			<![CDATA[That's not right. LHS is 1090mm, perpendicular to base rail, and there is a RHS vertical of 155mm. (So yes it's not actually triangular - it's a trapezium). Look at the pics. <br /><br />Whipping out my original drawings the answer to tony's question is 24 degrees (24.07)]]>
