APEX is an innovative new siding system that improves upon virtually every single critical area of siding and trim performance and aesthetics.

APEX is made with Ultrex®, a patented pultruded fiberglass pioneered by Marvin®, that through a proprietary manufacturing process has been incorporated with an integrated acrylic finish.

This unique process provides APEX siding with its unmatched strength, high moisture and impact resistance, and bold, rich colors that resist fading and don't require painting. The sum of which gives your home a truly distinctive look and enduring beauty.
