Good for you - I just hope you don't pull a gomberg some day.

Two points: 

1) Older houses aren't all that well sealed. 

B) New houses and buildings that have better sealing are being blamed for "sick 
building syndrome". 

The original poster was asking how to tightly seal a tank to reduce CO2 loss. 
Since the typical practice here is "more is better", I want to dissuade that 
person and others from going overboard. IMHO, trying to seal a tank is still a 
bad idea. YMMV. Do what you want; it's your tank.
