Doors are among the first touch-points a client or homeowner interacts with. They help define the feel of a space even before someone sets foot inside. But beyond visual appeal, high-quality doors also:
With that in mind, let’s break down the key door types available and which situations they’re best suited for.
Fiberglass doors continue to gain popularity for modern homes. They offer the look of real wood without the risk of warping, swelling or weather-related deterioration.
Best application: External entry doors, high-traffic areas, humid climates.
Hollow core interior doors are a go-to for many builds because they deliver a clean look at an affordable price point.
Benefits of hollow core doors
Best application: Bedrooms, wardrobes, and other low-noise interior areas where affordability is a priority.
Iron doors aren’t just secure — they’re visually striking. With bold profiles and customisable designs, they’re ideal for premium builds where the entryway is a focal point.
Best application: Modern luxury homes, upscale renovations, or properties requiring extra security.
For homeowners who value privacy and acoustic performance, solid core doors strike an excellent balance between cost and quality.
Best application: Home offices, bedrooms, or any space requiring privacy or peace and quiet.

Q1: Are fiberglass doors better than wooden doors?
Fiberglass doors offer better moisture resistance and require far less maintenance than wood. However, wood still provides a natural, premium look for high-end projects.
Q2: Do hollow core doors last long in high-traffic homes?
Hollow core doors are ideal for low-to-medium traffic areas. For busy households or rental properties, solid core or engineered-wood doors may offer better durability.
Q3: Can iron doors be customized?
Yes. Iron doors are highly customizable in terms of size, design, and glazing, making them ideal for statement entryways in modern homes.
Q4: Which interior door is best for sound reduction?
Solid core interior doors provide better acoustic insulation than hollow core models and are often used for bedrooms and offices.
Q5: Are modern doors energy efficient?
Yes, particularly fiberglass and insulated steel doors. Their construction often includes thermal breaks and weather-tight seals to minimize energy loss.
