Best airtightness rating for brick and block

[SBMS]

For those self builders that went with traditional masonry/brick and block and aimed for high levels of airtightness, what was your ACH figure? Trying to get a sense of what’s achievable with careful detailing!

Most of the site houses I work on seam to aim for 2 It many years since I’ve actually seen an airtightness test being done Most are done as a desktop study 

We’ve built traditional)Solid) the last two times Our present home is extremely airtight and the one we are currently finishing should be the same 

When we are ready for sign off Probably six months after moving in We will tip up our 200 quid and get our pass certificate 

Get your house as airtight as possible But don’t take the corrupt testing to seriously Because Red Row and Barratts will hit a lower score than you without trying

Passivhaus standards can be met with any build method. So you achieve whatever you want.

.31 ACH.

 

It needs attention to detail mind you.
