What standard is referenced for low temperature flexibility testing for SAF?

ASTM C765 or D1970

The key performance attribute for adhesion is:

a general function

Maintaining a reliable moisture seal.

The attribute ‘compatibility’ refers to;

Information required for maintaining a secure bond to various substrates

The key performance attribute for treatment of penetrations is:

The flashing should maintain water resistance at penetrations.

What is the key performance requirement set forth by ASTM E 2112 for flashing materials

In what circumstances can mill-finished aluminum flashing be used:

When fully concealed.

What is the minimum thickness for metal for head flashing?

26 ga or 0.040" (40 mils)

Why should aluminum be separated from other metals in flashing assemblies?

To prevent galvanic action and corrosion.

What standard is referenced regarding installation of windows in masonry construction?

FMA/AAMA 200

In window openings in masonry walls, where and when should FAF be installed per FMA/AAMA 200
