[Equest-users] Storefront and Curtainwall

[Peter Hillermann]

To All,

 

I'm about to answer my own question. The ASTM E283 is the maximum allowable
air infiltration for a weather tight system. The 0.06 CFM is a not to exceed
number. What the vendor will typically write is follow ASTM E283 to make
sure the system does not exceed 0.06 CFM of air infiltration. Its testing
pressure differences across the building envelope.

 

So the answer to my own question is 0.06 CFM is fine.

 

Thanks,

 

PETER HILLERMANN

To All,

 

Does anyone know what a good number of CFM is for air leakage in storefront
and curtainwall systems. At the moment I am being told 0.06CFM and as an
uneducated window system person I have no idea if that is appropriate. This
is tested against a ASTM E 283 at a test pressure of 6.24 psf, which for me
might as well have been written TYDOISJLAKHJSDMNKAPOD.

 

Thanks,

 

PETER HILLERMANN
