..to get an insulation uvalue done for a build I'm going undertaking. It is a full renovation of a property that's been vacant 12 years along with an extension. Full property size will be circa 180 meter sq. 4 bedrooms. Please see drawing attached. Will be looking to insulate underfloor and internally slab all walls. I just want to work out uvalues when all included sich as windows l, attic, underfloor, slab etc. Thanks, Mike
