Profile Closures

Profiled closures are available for all profiles. They are available in narrow tip (for going under the profile) or a wide tip (for fitting over).

A printable bulletin is available at: BPC01 Profiled Foam Closures.
Extract:
"The NZMRM Metal Roof and Wall Cladding Code of Practice recommends profiled foam closures
only where required for weather tightness. This typically occurs around windows of wall cladding.
Acceptable Solution E2/AS1 says profiled foam closures should not be used at the eaves."

As they restrict the free movement of air, their use should be restricted to where they are required for weatherproofing and appearance (such as scribers under window jamb flashings) or for maintaining positive internal pressures, such as in a building with a managed internal environment. Profiled closures should be of closed-cell type, rather than bitumen impregnated.

In marine areas, corrosion is likely to initiate under apex flashings and under the eaves overhang, regardless of whether profiled foam is used. A high fronted spouting is the best protection against eaves corrosion. (See Eaves Flashing)
