LOFT INSULATION, EAVES, PURLIN...etc.....HELP!!!

Hello all.... :D

After looking at various pieces of information I have finally decided I need to post something.

I am insulating my loft. Not a giant loft and I have no intension of converting it to anything other than storage space. The only thing is, before I board it I need to lay the insulation (roll). Now this is easy enough, but the 'Purlin' (I learnt that word recently ) seems to be in the way of insulating up to the eaves. There is a gap of around 3 feet from the eves to the purlin board. Yes, I said board..!!

Now, I'm not overly up on loft construction and what I have read is that purlins are the vertical beams coming from the roof to the joists. However, I seem to have a massive 4" thick piece of wood running the length of the loft stopping me from insulating behind it. I can't even get behind it. As the joists continue behind it there are also some intermediate battens, so if I were to push some insulation through under it would stop way before it reached the eaves (I know to leave a gap by the eaves).

Pics show the big board which runs from all to wall, the intermediate battens behind the purlin (which I photgraphed by putting my hand through the gap, sorry about the spider :shock: !) and an image I made up (to scale) with dims of the joists etc.

Any ideas on how to insulate this area would be appreticated. Was thinking about loose fill or King Span but again, it's getting it in there!

Many thanks...

pimpslider,
Can only suggest vermiculite - shovel it over the top of the board and spread it out as best you can.

Yeah, I've been looking at 'Warmcel 100'. Was thinking about just getting some piping or something like guttering and tipping it over the top. Blooming annoying. Who designs these things?!?!?!
