When it comes to building or renovating a property, selecting the best doors for home isn’t just a finishing touch — it’s a decision that impacts performance, security, aesthetics, and long-term value. Whether you’re a professional contractor sourcing products for residential projects or a homeowner planning a new build, choosing the right interior doors, fiberglass doors, or iron doors requires a balance of design insight and technical expertise.

At Spire Building Supplies, we’ve spent years providing best-in-class doors to builders and homeowners across the country. Our commitment to quality materials, trusted brands, and expert advice allows us to guide you toward doors that don’t just look good — they perform beautifully for years to come.

Why Choosing the Best Doors Matters

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:

• Improve energy efficiency
• Increase property value
• Add a measurable layer of security
• Enhance the user experience inside the home
• Reduce long-term maintenance costs

With that in mind, let’s break down the key door types available and which situations they’re best suited for.

Fiberglass Doors – Style Meets Durability

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.

Why builders choose fiberglass doors:

• Resist moisture, heat and humidity
• Low maintenance and easy to clean
• Highly customisable in terms of colour and finish
• Excellent energy efficiency
• Cost-effective for large-scale projects

Best application: External entry doors, high-traffic areas, humid climates.

Hollow Core Interior Doors – Lightweight & Cost-Efficient

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

• Lightweight and easy to install
• Budget-friendly for multi-unit builds
• Available in a wide range of styles
• Perfect for spaces where sound control is not a top concern

Best application: Bedrooms, wardrobes, and other low-noise interior areas where affordability is a priority.

Iron Doors – Security With Timeless Appeal

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.

Notable advantages:

• Outstanding structural strength
• Long-term durability
• Suitable for custom or oversized entry openings
• High resale and curb appeal value

Best application: Modern luxury homes, upscale renovations, or properties requiring extra security.

Solid Core Interior Doors – Added Sound Control

For homeowners who value privacy and acoustic performance, solid core doors strike an excellent balance between cost and quality.

Why they’re worth considering:

• Greater sound insulation
• Added weight enhances the “premium” feel
• More resistant to dents and impact
• Better at keeping heat where it belongs

Best application: Home offices, bedrooms, or any space requiring privacy or peace and quiet.

Frequently Asked Questions – Best Doors for Home

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 customised?
Yes. Iron doors are highly customisable 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 minimise energy loss.
