Associated Materials Innovations (AMI) is expanding its ASCEND® Composite Cladding line with a full suite of color-matched accessories engineered to help contractors make full-system installs more efficient and visually unified. Launching just in time for peak siding season, the new J-Channel, trims and outside corner post profiles create a high-end finish with no caulking, sealing or painting required. Now available to order, ASCEND accessories are a professional-grade solution for worksites navigating today’s labor crunch.

Edge it. Trim it. Elevate Every Detail.

Offered in a wide range of classic and contemporary colors—including recent arrival Cape Cod Gray— the new accessories are color-matched to ASCEND 7″ Plank and 12″ Vertical Board & Batten cladding that enhances exteriors from edge to edge. They also match in performance, with pro-focused features like longer lengths, durable construction and lightweight handling. Available SKUs include:

• J-Channel – 12′ lengths, 32 pieces/carton, available in all 21 colors.
• 3.5″ Trim and 5.5″ Trim – 16′ lengths, 10 pieces/carton, available in seven colors.
• 3.5″ Outside Corner Post – 12′ lengths, 10 pieces/carton, all colors.

The ASCEND line delivers exactly what pros are asking for: an inspired aesthetic paired with high-performance materials and complemented by crew-ready construction. The new accessories are available just in time for the busy summer building season, giving contractors and remodelers a solution to streamline their siding jobs and delight homeowners.

“ASCEND is already known for performance, visual appeal, and working the way pros like it to,” said Ryan Gibson, business director for vinyl and composite cladding at AMI.  “With these new accessories, we’re extending that same standard of excellence to every edge, corner and transition so installers can maintain momentum, stand out with a polished finish and earn more positive reviews.”

Built on the same technology platform that powers ASCEND’s lightweight, weather-resistant composite panels, the new accessories are designed for longevity, low maintenance and simplified on-site use. By offering a full system—from panels to trim that don’t require sealing, caulking, painting or any special prep or tools—contractors can sell the total exterior and deliver a cleaner, more consistent finish.

Building professionals appreciate efficient installations and products that look premium without complicating the process, and that’s why ASCEND is built to reduce complexity while raising the bar for what a cladding system can do.
