XtremeTrim® Reveal Trim System

Sustainable, durable, non-combustible, lightweight, easy to use, for interior or exterior use—that’s XtremeTrim®. Available in primed (ready to paint), color match, and anodized finishes.

Architects are concerned about the longevity of the products they specify. While galvanized trims are initially less expensive, they do not perform as well as aluminum in the long run.

All sidings can allow water to penetrate and need a cavity/drainage system, make sure your experience is a positive one by specifying TamlynWrap® behind the siding.

How XtremeTrim® works

While we design all our reveal trim with drain dams for vertical runs and shingle fashion for horizontal reveal trim profiles, its primary design is for aesthetics.

Drainable TamlynWrap®

TamlynWrap's unique design removes at least 100 times more bulk water from a wall versus standard housewraps. This is achieved through the gap created by 1.5 mm spacers bonded to a high performance housewrap.

XtremeBlock Mounting Blocks

XtremeBlock has been uniquely designed to maximize moisture movement away from the envelope of the structure while offering a pleasing appearance. Lightweight, easy to install, primed - ready to paint or prefinished to match the siding color.
