Interlock Aluminum Wall Cladding Uses Identical Panels and Coating as Its Lifetime Roofing System

Delta, Canada – July 8, 2026 / Interlock Roofing Ltd. /

DELTA, British Columbia – July 7, 2026 – Interlock Roofing Ltd. has expanded its product offerings to include Metal Siding and wall cladding panels, bringing the same heavy-gauge aluminum construction used in its lifetime roofing systems to a building’s exterior walls. The new panels share the same Alunar Coating System, profiles, colors, and trims as Interlock’s roofing line, enabling a home’s roof and walls to carry a unified, color-matched aluminum finish.

Interlock has established its standing in the industry through aluminum roofing engineered to last the life of a structure. By applying that same material system to vertical surfaces, the company now allows a home’s roof, chimneys, dormers, gables, and walls to share a single aluminum composition. This approach removes the compatibility concerns that can arise when roof and wall products originate from separate manufacturers, and it simplifies both installation and warranty coverage across every exposed exterior 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.”

The Metal Siding line is available in four architectural profiles – Slate, Cedar Shingle, Shake, and Standing Seam – which can be combined within a single color family. Panels are finished with the Alunar Coating System, a multi-layer architectural coating incorporating Cool Roof infrared-reflective pigments that reduce solar heat gain on walls. Non-combustible aluminum construction carries a Class A fire rating (available), a practical consideration in wildfire and ember-zone regions.

Because aluminum does not absorb moisture, the Aluminum Wall Cladding panels will not rot, warp, or crack through repeated freeze-thaw cycles. The factory-baked finish resists chalking and fading, eliminating the need for repainting over the product’s service life. The system also resists insects and coastal salt-air corrosion. Four-way interlocking panels install over most existing wall substrates through certified installers and require no painting, sealing, or staining after installation. The aluminum is largely recycled in content and approximately 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.
