What are Composite Doors?
Composite doors are modern entrance doors constructed by combining several materials, each chosen for its specific properties. Unlike traditional doors made solely from timber or uPVC, composite doors feature an engineered timber or foam-filled solid core for robustness and thermal efficiency. This core is encased in a durable, weather-resistant outer layer, often made from glass-reinforced plastic (GRP), which mimics the appearance of wood but resists warping, cracking, and fading over time.
The result is a door that offers the best attributes of every material used, outstanding security, excellent energy efficiency, and long-lasting good looks. Composite double glazed doors also incorporate advanced multi-point locking systems and toughened safety glass, further enhancing their security and insulation properties. Available in a wide range of designs, colours, and finishes, composite doors can complement both modern and traditional homes, making them a popular choice for homeowners across the South East.
Are composite doors secure
Our composite double glazed doors in Berkshire come packed with advanced features designed to keep you and your loved ones safe:
- Toughened safety glass: Every door unit includes internal toughened glass panels, protecting against impacts and intrusions.
- Internal beading: The glazing on our composite doors is securely fitted from the inside, adding another layer of security and making it near impossible for panes to be removed from the outside.
- Multi-point locking: All doors are installed with reinforced multi-point locking systems, reducing the risk of forced entry.
- PAS 24 compliant options: For additional reassurance, we offer PAS 24 enhanced security options, rigorously tested to meet recognised industry safety standards.
- Durable outer skin: The high-impact resistant GRP skin not only protects against the elements but also adds real strength and durability.
- Anti-snap cylinders & security hinges: Fitted as standard, these components deter and resist common techniques used by intruders.
- Custom security upgrades: If you have specific needs, we are happy to discuss even more advanced secure composite doors solutions for your property.
Choosing SK Double Glazing Ltd means choosing a level of security that truly protects your home, family, and possessions.

Questions about composite doors
What is a composite door?
A composite door is made from multiple materials, typically including a timber core, uPVC, fibreglass and reinforced frames. This combination offers excellent security, insulation and durability compared to single-material doors.
Why choose a composite door over uPVC?
Composite doors are more robust, energy efficient and secure than standard uPVC doors. Their solid core construction provides superior insulation, longevity and a choice of modern or traditional designs for your home.
Are composite doors secure?
Yes. Our composite doors in Berkshire include toughened safety glass, reinforced frames, multi-point locking, internal beading and can be supplied with PAS 24 compliant security for maximum protection.
How long do composite doors last?
With quality installation, composite double glazed doors can last 20 years or more. SK Double Glazing Ltd provides a 10-year insurance-backed guarantee with every composite door installation.
Can I customise my composite door?
Absolutely. Choose from a wide range of colours, finishes, glazed panel styles and hardware to create a modern or traditional composite front door that matches your property.
Do composite doors require maintenance?
Composite doors need very little maintenance. Simply wipe them down occasionally with a damp cloth. They do not warp, flake or require painting like timber doors.
