Composite Doors vs uPVC Doors — Which Is Right for Your Scottish Home?
If you're replacing your front or back door, two options come up more than any other: composite doors and uPVC doors. Both are popular, both are widely available — but they're very different products with different strengths.
What Is a Composite Door?
A composite door is built from multiple materials bonded together — typically a GRP outer skin, a timber or foam inner core, and a uPVC or aluminium frame. The result combines the appearance of solid timber with the weatherproofing and low maintenance of modern plastics. Solidor, one of the brands we stock, use a 48mm solid timber core — giving their doors a weight and solidity that's immediately noticeable.
What Is a uPVC Door?
A uPVC door has a hollow uPVC frame filled with steel reinforcement. They're lighter than composite doors and typically less expensive. Modern uPVC doors have improved enormously — they're far more thermally efficient and secure than older versions — but they still don't match the solidity or aesthetics of a quality composite door.
Security
Both can be fitted with high-security multi-point locking. The key difference is the door itself — a composite door's solid core is significantly harder to break through than a hollow uPVC door. For a front door, we'd always recommend composite over uPVC if budget allows.
Insulation
Composite doors generally outperform uPVC for thermal insulation, particularly those with a solid timber core. That said, modern uPVC doors with good weatherseals still perform well — the gap is narrower than it used to be.
Appearance
This is where composite doors win convincingly. The GRP outer skin replicates the appearance of real painted timber — deeply convincing at close range. uPVC doors, despite improvements, still look like plastic up close. If kerb appeal matters, composite is the better choice.
Price
uPVC doors are generally less expensive than composite doors. However, the gap is often smaller than people expect, and the long-term benefits of composite — better security, insulation, appearance and durability — often make the extra investment worthwhile.
Which Should You Choose?
For most Scottish homeowners replacing a front door, we'd recommend a composite door. For back doors or utility areas where appearance is less important, uPVC can be a cost-effective choice.
