Introduction

When homeowners say “siding” and contractors say “cladding,” they’re usually talking about the same thing: the protective exterior shell of a building. Whether it’s vinyl siding on a home in Whitby or ACM panels on a Toronto office tower, your exterior finish plays a major role in energy efficiency, durability, and overall curb appeal.

With rising energy costs and updated Ontario building codes, 2025 is the year where siding and cladding choices matter more than ever. Here are the top systems trending in the GTA and Durham Region right now.

1. ACM Panels (Aluminum Composite Material)

• Why it’s popular: Modern, lightweight, and stylish. Common in Toronto condos and commercial storefronts.
• Energy benefit: Works with continuous air/vapor barriers for superior insulation, lowering HVAC costs.
• Best use cases: High-rise towers, retail podiums, office buildings.

2. Trespa HPL (High-Pressure Laminate) Siding/Cladding

• Why it’s popular: Bold design, UV stability, and weather resistance.
• Energy benefit: Long-lasting thermal performance with low maintenance.
• Best use cases: Schools, hospitals, and public buildings across Durham.

3. Corrugated & Profiled Steel Siding

• Why it’s popular: Durable and cost-effective, especially for industrial parks.
• Energy benefit: Strong insulation when paired with vapor barriers and spray foam.
• Best use cases: Warehouses, logistics facilities, commercial plazas.

4. EIFS (Exterior Insulation and Finish Systems)

• Why it’s popular: Lightweight, versatile, and extremely energy efficient.
• Energy benefit: Continuous insulation reduces thermal bridging, which is key under Ontario’s 2025 codes.
• Best use cases: Hotels, mixed-use plazas, mid-rise developments.

5. Eco-Friendly & Emerging Options

• Examples: Bio-based siding, recycled composite panels, and BIPV solar façades.
• Energy benefit: Combine insulation with renewable energy or reduced carbon footprints.
• Best use cases: Projects targeting LEED certification or ESG investors.
