A New Recommendation – Party Wall Insulation
The 9.93 update includes a new recommendation which will be displayed on the EPC.
In instances where the party wall type is input as “cavity masonry, unfilled”, it is likely to produce
a recommendation. This would make identifying the appropriate type of party wall even more
important.
As per RdSAP Convention 3.16: The primary method of identification is from a view of the
party wall within the loft space. With brickwork, solely stretcher bonds indicate cavity
construction while stretchers and headers indicate solid wall construction. A solid blockwork
wall has blocks laid flat; the pattern looks like stretcher bond but the unit size is much larger.
