Structural benefit of steel doors

Benefits of Steel Doors

Durability
Window Mart’s Steel Entry Doors are created for durability. Each door features a unique door skin that uses stiles to form a j-bend edge. This specialty manufacturing technique creates an exceptionally sturdy door with superior resistance to delamination.

Strength and Security
Our doors are designed to be both visually appealing and remarkably strong. Each door utilizes a full-length steel reinforced wood lock block to provide enhanced security while also allowing for the versatility of a wide selection of hardware mounting options.

Energy Efficiency
Doors are notoriously known for energy loss. Our steel doors utilize 100% CFC-free polyurethane foam to insulate your home and provide superior performance to every specification — including an impressive R-value and U-value.

Questions to ask when choosing steel doors:

What makes steel doors a good choice for Canadian homes?

Steel doors are strong, secure and durable, making them ideal for Canada’s weather extremes — from frigid winters to warm summers. Their construction resists warping and cracking, and insulated cores help keep your home comfortable year‑round.

How do steel doors compare to wood and fiberglass doors?

Steel vs Wood: Steel offers stronger security and better resistance to moisture and temperature swings — with minimal maintenance — while wood needs regular sealing and care.
Steel vs Fiberglass: Fiberglass resists dents better and can mimic wood grain, but steel provides superior security and are typically sold at a lower price point.

Are steel entry doors energy efficient?

Yes — quality steel doors have insulated cores and tight weather sealing that reduce heat loss and help maintain stable indoor temperatures, which can lower heating and cooling costs.

Do steel doors improve home security?

Absolutely. Steel doors are inherently strong and hard to breach, especially when paired with multi‑point locks and reinforced frames — giving you protection that’s tough to match with other materials.

Can steel doors resist Canadian weather?

Yes. Steel doors are designed to withstand harsh weather, resist moisture damage, and stay solid through freeze‑thaw cycles, making them well‑suited to Alberta, Saskatchewan, BC and Ontario climates.

Are steel doors noisy or drafty?

No — with proper insulation and weatherstripping, steel doors can provide excellent thermal and sound insulation, helping reduce drafts and outside noise.

Are steel doors noisy or drafty?

No — with proper insulation and weatherstripping, steel doors can provide excellent thermal and sound insulation, helping reduce drafts and outside noise.

Do steel doors require maintenance?

Steel doors are low maintenance — requiring only occasional cleaning and inspections of weather seal and hardware. Unlike wood, they don’t need regular refinishing or sealing.

What’s the expected lifespan of a steel door?

With quality construction and proper installation, steel doors can provide decades of performance — often 20–30+ years — without major repairs.

Can steel doors be painted or refinished?

Absolutely — many steel doors have finishes that can be repainted if you want to refresh the look or update your home’s exterior style.

Do steel doors look “cheap” or plain?

Not at all. We use High-Definition Embossing technology. This allows us to press deep, rich panel designs into the steel that mimic the shadow lines and character of traditional high-end wood doors. You can choose from classic multi-panel styles to sleek, modern minimalist designs that boost your home’s curb appeal instantly.
