Buyer's guide

Types of exterior doors: materials and styles compared

Your front and exterior doors handle security, energy efficiency, weather and first impressions. Choosing the right material and style pays off in all four. Here are the main exterior door types and how to pick.

Key takeaways

What to consider before you choose

Security

Entry doors should be solid and paired with quality locks and strong frames. Steel and solid fibreglass resist forced entry best.

Energy efficiency

Insulated cores and good weatherstripping cut drafts and bills — a drafty door wastes heat all winter.

Maintenance

Wood needs refinishing; steel and fibreglass are lower-maintenance, though steel can dent and rust if damaged.

Looks and light

Glass inserts and styles affect light and curb appeal — balance looks with privacy and security.

FAQ

What's the most secure exterior door?

A solid steel or heavy fibreglass door paired with a quality deadbolt and a strong frame offers the best security against forced entry.

Steel or fibreglass door — which is better?

Steel is more affordable and very secure; fibreglass is lower-maintenance, resists dents and can mimic wood. Both are energy-efficient.

Do exterior doors improve energy efficiency?

Yes — an insulated door with good weatherstripping cuts drafts and heating bills. A drafty old door is a common source of heat loss.
