5 line walls ?

Well, It seems this function is somewhat dependant on which country we live
in. As it's nearly always raining here in the U.K. All of the domestic
market builds with 300mm approx. wide cavity walls. Both leaves of masonry
with a clear cavity of 50mm is required under our building reg's. Then our
thermal values are bumped up a bit with partial insulation within the
cavities, say 35mm wide insulation boards held in position with retaining
ring type cavity wall ties. We also use insulation blocks as well on the
inner leaf some of the time as well.

So, we could do with five line walls for the cavity walls we draw just for
the insulant, which is all the time with the domestic market.
Even our timber frame houses have a 50mm clear cavity off the timber frame &
then is usually clad externally with face brick or block render.
