Who this guide is for
- Owners choosing an entry or patio door material.
- Anyone weighing security, maintenance and appearance.
- Homeowners briefing a door supplier.
Wood
Wood doors offer a classic, substantial look and can be refinished, but they need maintenance to handle weather. They suit households happy to care for them for the appearance.
Metal
Metal doors are valued for strength and lower maintenance, and feature in many secure entry designs. Appearance and thermal behaviour vary by product, so compare specific ranges.
Glass
Glass features in patio doors and glazed entry doors for light and views. Safety glazing and how it's framed and fitted are central, which makes specification and fitting professional decisions.
Composite categories
Composite doors combine materials to balance security, maintenance and appearance, and are a popular entry-door category. Products vary; compare specific ranges and follow manufacturer guidance.
Security as a planning topic
Security comes from the door, frame, glazing and locking as a system, plus correct fitting — not from material alone. Treat it as a planning topic to discuss with the supplier.
Weather exposure, maintenance and professional fitting
Match the material and finish to the door's exposure, weigh the maintenance you'll do, and use qualified installers — fitting affects both security and weather performance.

Common mistakes to avoid
- Choosing a door on looks without weighing exposure or security.
- Assuming material alone makes a door secure.
- Overlooking safety glazing in glass doors.
- Treating a category as one uniform product.

- Skipping professional fitting.
When to involve a professional
- Security depends on the whole assembly and correct fitting — professional work.
- Door fitting and weather-sealing must be carried out by qualified installers.

Frequently asked questions
Questions readers ask about this topic
Which exterior door material is most secure?
Security comes from the door, frame, glazing and locking as a system, plus correct fitting — not from material alone. Discuss it as a system with the supplier and use qualified installers.
Which door material needs least maintenance?
Generally metal and composite doors need less than wood, though it varies by product. Weigh maintenance against the appearance you want.
Are glass doors a security risk?
Not inherently — safety glazing and how the door is framed and fitted matter. Specify glazing with the supplier and use qualified installers.
