Aluminum Trim by XtremeTrim®

Aluminum Trim - While we design all our reveal panel trim with drain dams for vertical runs and shingle fashion for horizontal reveal trim profiles, its primary design is for aesthetics. XtremeTrim® reveal panel system will not stop water from penetrating the surface of the cladding. The primary insurance of moisture mitigation for the building envelope is your house wrap or a drainable housewrap. Other options are to use skin venting along with your house wrap. We recommend that you consult your manufacturer for best practice application when installing our reveal trim with their siding. As all building professionals know, water is the most significant factor in the premature deterioration of buildings, and proper steps should always be taken to protect the envelope.

Leakage paths exist at any opening in the wall surface, whether intended or unintended. Joints between materials and around windows and doors, vents, cracks, and porous surfaces are all potential entry points for water. This is why all roof parapets must be properly sealed with flashing membrane and all windows and door openings flashed in shingle fashion.

All XtremeTrim® aluminum trim profiles do not form a moisture management system. The architect, builder, designer and contractor are responsible for designing and installing a code compliant building envelope. Below are the code minimum requirements.
