When homeowners, contractors, builders, and remodelers evaluate exterior cladding, durability is usually one of the first questions on the table. That is especially true when the choice is between wood, fiber cement, or a newer composite alternative like ASCEND® Composite Cladding.
Wood can deliver a warm, authentic look, but it often brings maintenance concerns. Fiber cement has earned a strong reputation for durability, but homeowners may still weigh the upkeep, finish maintenance, and long-term appearance questions that come with the material.
ASCEND gives the market another option: a low-maintenance composite cladding system that delivers the look of real wood while helping reduce worries around moisture and upkeep.
That makes the cladding conversation more practical. Will it hold up to weather? Will the color last? Will the finished wall look clean not just on day one, but years down the road?
To answer those questions, we spoke with Ryan Gibson, Senior Business Director of Vinyl, Composites and Metals, about how ASCEND is engineered and what durability means in today’s home exterior applications.
Q: When people ask whether ASCEND Composite Cladding is durable, where do you start?
Ryan Gibson: I start with the idea that durability is never one feature, it is the result of how the whole cladding system is engineered, from the material formulation to the panel structure to the way it performs once installed.
ASCEND uses composite construction, built around exclusive (GP)² Technology, which combines glass-reinforced polymer with graphite-infused polystyrene. The polymer component contributes strength while the polystyrene backing supports thermal performance and adds structure behind the panel, helping it to feel solid and substantial on the wall.
Think of it like the way a vehicle is engineered: the outer body is designed for stability and protection, while the materials beneath help manage comfort and performance. In ASCEND, that layered approach is also supported by “protective ingredients” such as UV stabilizers, impact modifiers, weatherable pigments, and flame retardants.
The same system-level engineering carries through to installation as well. Features like a reinforced nail hem, self-aligning lock design, and integrated backing help panels install efficiently while contributing to the strength, rigidity, and clean finished appearance homeowners expect over time.
ASCEND Composite Cladding continues to earn industry recognition for its premium design and proven performance, including a 2026 Good Housekeeping Home Reno Award for ASCEND 12″ Board & Batten.
Q: How does ASCEND stand up to moisture?
Ryan: ASCEND is designed to help avoid moisture-related problems because its composite materials are non-absorbing. The panel does not rely on paint, caulk, or surface treatments as its primary moisture defense; the resistance is built into the material itself.
There’s also an advantage behind the panel: ASCEND’s integrated foam backing creates slight separation between the cladding and the weather-resistive barrier, producing a natural rainscreen effect that helps manage incidental moisture.
For homeowners, that means an exterior that shrugs off rain, humidity, and changing seasons. For contractors, builders, and remodelers, it means fewer worries about finish issues after the project is complete.
ASCEND uses non-absorbing materials that help prevent rotting, warping, shrinking, and swelling, while its integrated backing creates a natural rainscreen effect behind the panel to help manage moisture.
Q: What role does wind resistance play in cladding durability?
Ryan: Wind resistance tells you how well the panel, lock, and fastening system work together under pressure. In high winds, you need a system that can stay secure at the attachment points.
ASCEND is engineered with a polymer-reinforced nail hem that gives the panel added rigidity along the fastening edge and helps protect against fasteners pulling through the material under load. Paired with a self-aligning lock design, it helps the product stay securely engaged across the wall, which can contribute to a more efficient installation process as well.
Wind resistance is also supported by profile-specific testing measured in psf, or pounds per square foot. PSF measures how much wind pressure a wall surface can resist. ASCEND 7″ Plank is tested at 53 psf with nails at 24″ on center and 1-1/4″ penetration. ASCEND 12″ Board & Batten is tested at 52 psf with nails at 12″ on center, 65.3 psf with nails at 8″ on center, 66.4 psf with staples at 12″ on center, and 120.9 psf with staples at 8″ on center.
The higher the number, the lower risk of blowoff in storms. That gives builders and contractors a clear path to match the installation approach to the project’s wind-load requirements. Those results also reinforce that ASCEND’s wind performance comes from more than the panel face. It is tied to the reinforced nail hem, the (GP)² construction, and the way the product is properly fastened as a complete system.
An added benefit is that the nail hem fasteners are hidden, so there are no nail heads to touch up with paint—homeowners can get the crisp, uninterrupted look they want.
A reinforced nail hem adds strength along the fastening edge, helping ASCEND panels stay securely attached under wind load while keeping fasteners hidden for a cleaner finished look.
Q: Is ASCEND impact resistant?
Ryan: ASCEND is engineered to resist everyday impacts that can happen around a home or jobsite. Some cladding products rely mainly on thickness or surface finish, but ASCEND builds toughness into the material formulation itself. The formulation includes impact modifiers that help the cladding resist dents and dings while maintaining the right balance of rigidity.
That balance is important because a panel that is too stiff can become more vulnerable to cracking under impact. If it is too flexible, it may not deliver the sturdy-looking appearance you expect. ASCEND’s impact modifiers work within the broader (GP)² formulation to help it stand up to contact while maintaining its shape, and ASCEND 12″ Board & Batten has been tested at greater than 35 in.-lbs. impact resistance. For added homeowner confidence, ASCEND’s warranty also includes coverage for damage caused by hailstones up to 1″ diameter for qualifying claims.
Q: How does ASCEND protect against fading?
Ryan: Our cladding uses weatherable pigments to help deliver fade resistance, including darker colors, and the warranty offers non-prorated fade protection within 3 Hunter Delta E units. For homeowners, that means the color story is supported by a measurable fade standard and not just a promise that the product will look good, which is an important distinction: durability is about resisting damage and helping maintain the look the homeowner originally chose.
The lower the Delta E, the less visible the color change. ASCEND includes fade protection within Delta E 3, compared with fiber cement’s typical Delta E 4 allowance.
Q: What about fire-rated performance?
Ryan: ASCEND includes flame retardants as part of its engineered formulation and has achieved a Class A fire rating for both flame spread and smoke developed.
As always, local code requirements and project-specific conditions matter, so be sure to review the applicable product documentation and installation requirements for your market.
Q: What warranty coverage does ASCEND offer?
Ryan: The product is backed by a lifetime limited warranty for the original homeowner, with transferable coverage that can continue for future owners. That speaks directly to the appearance and durability that buyers tend to care about the most, including coverage related to manufacturing defects and finish performance like blistering, corroding, flaking, and peeling under normal use and service.
Q: What is the main takeaway for homeowners, contractors and builders?
Ryan: ASCEND Composite Cladding is durable because it is engineered as a system. The material formulation, insulating backing, locking design, weatherable finish, and accessory package all contribute to dependable performance.
That is the ASCEND durability story: engineered construction you may not see from the curb, but you can appreciate every time the exterior continues to look the way it should.
