ASCEND Composite Cladding combines a glass-reinforced polymer surface with graphite-infused insulation to deliver authentic wood styling, an R-value up to 2.0, wind-load performance up to 180 mph and a Class A fire rating.
Premium Composite Cladding for Midwest Homes
ASCEND Composite Cladding Is an Impressive Alternative to Vinyl and Steel Siding
ASCEND® Composite Cladding combines authentic wood-inspired aesthetics with insulation, impact resistance, wind-load performance and an installation system designed for contractor efficiency.
What Makes ASCEND Different?
ASCEND is not conventional vinyl siding, fiber cement or steel siding. It uses proprietary (GP)2 Technology that combines a glass-reinforced polymer surface with a graphite-infused polystyrene core.
The outer surface is engineered to provide structural stability, impact resistance and a finished appearance that closely resembles painted or stained wood. The graphite-infused core adds insulation, rigidity and a more substantial profile.
That combination gives contractors a product positioned between traditional siding and more labor-intensive premium cladding systems.
ASCEND Technical Performance at a Glance
Up to 180 mph
Published wind-load performance with the required installation method and substrate.
Up to R-2.0
Thermal resistance from the integrated graphite-infused foam construction.
Class A
Manufacturer-published classification for flame spread and smoke developed.
21 colors
A broad palette of low-gloss, fade-resistant exterior colors.
Published ratings depend on the exact profile, assembly, substrate, fasteners and installation details. Confirm the applicable technical report for each project.
ASCEND Compared With Vinyl and Steel Siding
| Consideration | ASCEND Composite | Traditional Vinyl | Steel Siding |
|---|---|---|---|
| Construction | Glass-reinforced polymer surface bonded to a graphite-infused insulating core | Formed polymer panel; insulated versions are available separately | Formed metal panel; insulated systems vary by manufacturer |
| Published insulation | Integrated insulation with an R-value up to 2.0 | Depends heavily on whether an insulated backing is included | Depends on the complete wall assembly and whether separate insulation is used |
| Wind performance | Published performance up to 180 mph in qualifying assemblies | Varies significantly by panel profile, nail hem, lock and installation | Varies by panel gauge, profile, fastening and wall assembly |
| Impact behavior | Impact modifiers and glass reinforcement help resist everyday dents, dings and abrasions | Performance varies by panel thickness, formulation and temperature | Strong material, but visible denting may occur after certain impacts |
| Thermal movement | Engineered for lower expansion than conventional polymeric siding | Requires room for normal expansion and contraction | Metal also expands and contracts and must be installed for expected movement |
| Appearance | Deep 7-inch exposure, defined butt edge and wood-inspired texture | Broad selection of profiles, textures and price levels | Crisp lines and durable finishes with a distinctly formed profile |
| Field finishing | No painting, sealing, joint flashing, touch-up painting or routine joint caulking required by the standard system | Generally supplied with finished color and does not require painting | Supplied with a finished coating; damaged finishes may require approved repair procedures |
| Moisture absorption | Manufactured from non-moisture-absorbing materials that will not rot | Vinyl does not rot, but the wall assembly still requires correct water management | Steel does not rot, but cut edges, coatings and wall drainage must be handled correctly |
This comparison describes broad material categories. Vinyl and steel siding include many product grades and assemblies, so compare the published specifications of the exact products being proposed.
Why the R-Value Matters
ASCEND’s graphite-infused polystyrene core provides an R-value of up to 2.0. That insulation is integrated into the panel rather than installed as an unrelated layer.
Continuous exterior insulation can help reduce thermal bridging through framing members. It can also increase the interior surface temperature of the wall assembly during cold weather, although the actual whole-wall benefit depends on every layer of the construction.
ASCEND should not be presented as a replacement for all required wall insulation. Its R-value is an added component of the complete wall system.
Strong Wind-Load Performance
The reinforced nail hem and self-aligning stack lock contribute to published wind-load performance of up to 180 mph. That number is impressive, but it is not a promise that every installation will withstand every 180-mph weather event.
Wind pressure changes with building height, exposure, wall location, fastener spacing, substrate and local code requirements. Contractors must follow the installation guide and confirm that the tested assembly is appropriate for the project.
Class A Does Not Mean Noncombustible
ASCEND has a published Class A rating for flame spread and smoke developed. That is a meaningful surface-burning classification.
It should not be described as fireproof or noncombustible. A Class A rating addresses performance under a particular test method, while code compliance depends on the complete wall assembly and project conditions.
Installation Advantages for Contractors
- Lightweight panels are easier to handle than many heavier cladding alternatives.
- The self-aligning stack lock helps crews maintain consistent panel engagement.
- Standard installation does not require joint flashing, sealing, touch-up paint or joint caulking.
- The forgiving hang can help conceal minor wall irregularities.
- Coordinated trim and accessories help crews complete the exterior with a unified system.
“Easier” does not mean automatic. Contractors still need to follow the current installation guide for wall preparation, clearances, overlaps, fastening and water-resistive barrier integration.
Is ASCEND Better Than Vinyl or Steel?
ASCEND is not automatically the best product for every house, budget or architectural style. Quality vinyl siding can offer excellent value and a broad selection of profiles. Steel siding can provide strength, crisp lines and proven durability.
ASCEND becomes especially compelling when the homeowner wants a deeper wood-inspired appearance, integrated insulation, strong impact performance, less polymeric movement and efficient installation without the field finishing associated with some other premium cladding materials.
That combination—not one isolated specification—is why ASCEND deserves a place in a contractor’s premium siding presentation.
