Airtightness

[nod]

Just thought I’d share 

I’ve been sent drawings for a job (58 Houses)  to quote for the starting around Easter The spec is quite unusual 

Traditional build Brick and Block 

Internals are first sprayed with a pink liquid for airtightness Then all block walls are gypliner then insulated 

Then three layers of 15 soundblock 

Each layer acoustic sealed around perimeter all joints tapered Third layer skimmed 

 

I’ve just had an air test on ours 2 No special measures Pretty much what we do each day on sites 

Just thinking as I prepare this very expensive quote Is this all necessary 

Ive dabbed insulated boards on the perimeter walls Which in my humble opinion would be just as good and a fraction of the cost 

 

I’m pretty sure these will be local Authority So I suppose cost isn’t an issue 

[Mr Punter]

That sounds mad.  Why the soundblock?

 

Plumber and sparky will do their utmost to mess these up.

There in blocks of four 

Housing associations tend to go a bit mad but this takes it to another The pink spray is probably going to be expensive also
