Just doing a big of research and costings for floor insulation.  These 'ere upstands, what's the crack with these.  would/did you buy them ready made width and height, or would you just take some 25/50mm insulated boards and cut/trim it to the height required then stick it in place.  Something is telling me that cut boards would be more cost effective and i'm looking for reassurance that its ok to do this (not frowned on).  Or is there a better way?

If your referring to up stands around the perimeter or doorways

You can make those up onsite 

Thanks @nod
