Interlock Launches Aluminum Metal Siding & Wall Cladding: Same Lifetime Panels, Coating & Colors as Its Roofs

Delta, Canada – July 7, 2026 / Interlock Roofing Ltd. /

DELTA, British Columbia — July 7, 2026 — Interlock Roofing Ltd. has expanded its product line to include aluminum metal siding and wall cladding, extending its lifetime aluminum roofing system to a building’s exterior walls. The new panels are formed from the same heavy-gauge aluminum, finished with the same Alunar Coating System, and offered in the same profiles, colors, and trims as Interlock roofing, allowing a home’s roof and walls to share one color-matched aluminum finish.

Interlock has built its reputation on aluminum roofing engineered to last the life of a structure. By applying the identical material system to walls, the company now lets a home’s roof, chimneys, dormers, gables, and walls share one aluminum composition. This eliminates the compatibility questions that can arise when roof and wall products come from different manufacturers and simplifies both installation and warranty coverage across every exposed surface.

“Homeowners already trust our aluminum roofing to protect their home for a lifetime,” said Scott Plumptree, Director of Marketing, Interlock Roofing Ltd. “Extending that same panel, coating, and color system to siding means the entire exterior performs to one standard and reads as one intentional design.”

Interlock metal siding is offered in four architectural profiles — Slate, Cedar Shingle, Shake, and Standing Seam — which can be combined within a single color family. The panels are formed from heavy-gauge aluminum and finished with the Alunar Coating System, a multi-layer architectural coating with Cool Roof infrared-reflective pigments that reduce solar heat gain on walls. Non-combustible aluminum construction carries a Class A fire rating (available), an advantage in wildfire and ember-zone regions.

Because aluminum does not absorb moisture, the panels will not rot, warp, or crack through repeated freeze-thaw cycles, and the factory-baked finish resists chalking and fading, so the cladding never requires repainting. The system also resists insects and coastal salt-air corrosion. Four-way interlocking panels install over most existing wall substrates, fitted by certified installers, and require no painting, sealing, or staining over their service life. The aluminum is largely recycled in content and roughly 95 percent recyclable at end of life.

Interlock metal siding and aluminum wall cladding are available across the United States and Canada through certified local installers, for both new construction and re-cladding projects. Recent installations include custom homes in Whistler, British Columbia.
