Composite Cladding

Composite cladding is exterior wall or soffit paneling made by engineering wood fiber and a polymer binder into a single material, commonly called WPC (wood-plastic composite). Some composite cladding, including Geolam’s Vertigo 5010, adds a co-extruded aluminum core to that construction for additional structural and fire performance.

At its base, composite cladding combines wood fiber with a polymer binder. Geolam’s composite uses polypropylene rather than PVC. Aluminum-composite variants add an anodized aluminum core, hot co-extruded with the wood-composite face in one continuous manufacturing process.

Compared to solid wood, composite cladding generally offers better moisture resistance, a longer service life and less recurring maintenance, since the wood fiber is engineered into a stable material. Aluminum-composite constructions add ASTM E136 non-combustible fire performance, which a standard solid composite typically doesn’t carry.

Durability depends on the construction and the manufacturer. Solid WPC is a proven exterior material, but its warranty terms and fire performance vary widely. Vertigo 5010 pairs a co-extruded aluminum core with a wood-composite face and is backed by a 10-year non-prorated limited warranty covering splitting, rot, and termite or fungal decay.

It depends on the specific product. Many standard composites carry only a flame-spread rating, or no fire testing at all. Aluminum-core hybrid composites, including Vertigo 5010, are tested non-combustible under ASTM E136, a stricter classification than a flame-spread rating alone.

Not automatically. Whether a composite cladding product is non-combustible depends entirely on its construction, specifically whether it includes a non-combustible core like aluminum. Ask any manufacturer for their actual ASTM E136 test report rather than assuming from the word “composite” alone.

Yes, that’s its primary application. Composite cladding is engineered specifically for exterior walls and building exteriors, where it needs to resist moisture, UV exposure, and temperature swings over years of use, performance requirements a raw, untreated wood board doesn’t meet on its own.

Yes, exterior wall cladding is the primary use case for composite panels, on commercial buildings, residential buildings, and institutional buildings alike. The same material is also commonly used for soffits and, on some profiles, interior feature walls.

Yes. Vertigo 5010 is designed for exterior rainscreen use. The installation guide recommends a drainage plane behind the boards to allow airflow and water drainage, so any moisture that gets past the cladding can drain and dry instead of sitting against the building.

Vertigo 5010 can be mounted horizontally, vertically or diagonally, directly over a code-compliant air barrier or onto furring strips. Geolam recommends a drainage plane behind the boards and advises against sealing the top or bottom of the wall so air can circulate. Boards are fastened with stainless steel screws at up to 24 in. on center, with a 1/8 in. gap at butt joints, and a color-matched J-trim can cover exposed screws on the final board.

It depends on the finish. If the wood-look surface is genuinely part of the composite, sanded rather than painted, no staining or sealing schedule is required. Vertigo 5010’s routine care is soap and water only, with no refinishing cycle to plan around.

Solid wood offers genuine, unengineered grain but requires ongoing staining or sealing and is prone to rot, checking, and insect damage without that upkeep. Composite cladding trades a small amount of that raw authenticity for engineered consistency, less maintenance, more predictable weathering, and, in aluminum-composite constructions, a non-combustible rating solid wood can’t offer.

Solid or printed aluminum cladding is inherently non-combustible and extremely durable, but reads as metallic and offers a wood look only through a printed or dye-sublimated coating. Aluminum-composite cladding like Vertigo 5010 combines both: an aluminum core for the same structural and fire performance, wrapped in a genuinely sanded wood-fiber face rather than a graphic applied to bare metal.

Yes, façade cladding is one of the most common applications for composite panels, on new construction and retrofit projects alike. The same profile typically works across a full facade system, from ground-floor storefronts to upper-story elevations.

Vertigo 5010 ships in four standard colors, Teak, Moleskin, Rosewood, and Ebony, stocked in the USA with no minimum order, plus two non-standard colors, Carbon and Bilinga, available as special orders with a 90-day lead time. All colors share the same sanded, wide-slat plank profile.
