Norwood Mini by MAC Metal Architectural captures the pared-back elegance of Scandinavian narrow-strip cladding in pre-painted galvanized steel. At 3.4" exposure, it creates a refined, high-density plank pattern that stands on its own or combines seamlessly with the 5.38" Norwood profile for fully customizable mixed-width facades. The same TEXTURAL III & IV matte paint system, beveled anti-siphoning edge, and hidden-fastener system as Norwood — available in 15 colours across Wood Grain and Metallic collections.

About Norwood Mini

MAC Norwood Mini is a narrow 3.4" pre-painted galvanized steel siding panel that shares the same beveled anti-siphoning profile as MAC's standard Norwood plank — built in a smaller footprint. The anti-siphon geometry prevents water from being drawn up and behind the panel by capillary action, a common failure point on narrow-plank steel cladding in high-rainfall or coastal environments.

Norwood Mini is purpose-built to pair with the full-width Norwood plank (5.38"), creating a two-plank Scandinavian-inspired horizontal facade with intentional rhythm between narrow and wide boards. Available in 15 standard MAC colours, it installs with no exposed screws. A vented soffit version of Norwood Mini is also available for continuous soffit runs that need to breathe. MAC's standard paint warranty covers all colour options.

Available at Pro Materials in Newmarket, Ontario, supplying contractors, builders, and homeowners across York Region, the GTA, and Ontario. All products are available on a quote basis; contact us for wholesale pricing and current availability.

Installation Guide

Wood Collection panels come in 6 plank variations per colour (numbered #1–6 on the back). Install in random order — never follow numerical sequence to avoid a wallpaper effect. Boxes come pre-mixed; each box contains 12 × 12-foot planks = 41 sq. ft.
Norwood Mini (3.4" exposure) can be combined with Norwood (5.38" exposure) on the same wall to create varied Scandinavian-style mixed-width strip patterns. Calculate the combined layout before starting installation.
Store panels indoors in a dry, well-ventilated area. If outdoor storage is necessary, place away from direct sunlight and extreme temperatures — heat causes the protective film to adhere more strongly, making removal difficult. Cover with a tarp.
Do NOT install over ZIP System Insulated R-Sheathing or similar dual-composite panels — insufficient rigidity causes movement, deformation, and oil canning under varying weather and sun exposure.
Install Starting Strip (M10D) using a laser level or chalk line, 3" above the base of the wall. Secure with one screw first, verify level, then fasten fully. For vertical installation, replace M10D with M50D drip strip — no starter strip required.
Use MAC Anticorrosion screws (A059.250 wood screw or A060.250 K-LATCH self-drilling) every 16" or 24" o.c. in the center of pre-punched holes. Drive with moderate contact only — do not overtighten. Screws must not exert upward or downward pressure on the panel.
Remove the protective film from panels before installation where possible to allow visual inspection of quality as work progresses.
Check alignment every 3–4 panels. If a furring strip section is not aligned, leave a small gap between the wall and the furring strip rather than forcing the panel — prevents excess pressure and oil canning.
Leave 1/8"–1/4" expansion gap between panel lengths at all longitudinal joints. On walls over 30 ft., install vertical expansion molding; on multi-storey structures, install horizontal transition molding at every floor.
For inside corners, install QJ Trim M22D and slide the panel end into the molding, leaving a 1/8" gap for expansion. For outside corners, install M20D (with integrated J Trim) before proceeding with panel installation.
Cut panels using the MAC Guillotine designed for Norwood siding, metal snips, or electric shears. Electric saws and angle grinders are NOT covered by MAC warranty.
Notify your supplier before installing more than 144 sq. ft. (2 boxes) if any product issue is discovered during installation to ensure warranty coverage is preserved.
