Composite doors are expertly engineered using a blend of high-performance materials, typically featuring a solid timber or high-density foam core wrapped in a tough, weather-resistant outer layer such as glass-reinforced plastic (GRP). This unique construction combines strength, durability, and visual appeal—making them a popular choice for both modern and traditional homes.
Superior Security
Composite doors are built with strength in mind. Reinforced frames, solid cores, multi-point locking systems, and anti-snap cylinders come as standard. These features offer outstanding protection against forced entry, often meeting or exceeding recognized security standards.
Long-Lasting Durability
Unlike timber, which can warp or rot, or uPVC, which may fade or crack over time, composite doors are built to withstand the elements for years. Their tough outer skin resists dents, scratches, and weathering—retaining their good looks with minimal upkeep.
Thermal Efficiency
Composite doors deliver excellent insulation. Their dense cores and tight seals help prevent heat loss and reduce energy bills. Many options feature low U-values, making them suitable for energy-conscious homeowners.
Low Maintenance
Say goodbye to sanding, painting, or staining. Composite doors only need a quick clean with soapy water now and then to stay in top condition.
One of the standout features of composite doors is the wide range of styles and finishes available. Whether you're after the timeless charm of a cottage-style door or a sleek, contemporary panel design, there’s a composite door to suit your taste. Choose from:
Woodgrain or smooth finishes
A full palette of colours, including popular greys, greens, blues, and classic whites
Glazing options like frosted, decorative, or clear glass
Hardware in chrome, gold, black, and brushed metal finishes
Thanks to customisation options, you can create a door that perfectly complements your home’s architecture.
Beyond appearance, composite doors allow you to tailor functional features to your needs. You can add:
Side panels for wider entrances
Spy holes or door knockers for enhanced usability
Designer handles and letterboxes
Matching internal and external colours
Each door is made to measure, ensuring a perfect fit and optimal performance from day one.
Most composite doors arrive prehung in their frames, fully fitted with locks and hinges, making installation straightforward. Reputable suppliers typically offer long warranties—often around 10 years—covering structural integrity, locking mechanisms, and colour stability.
While composite doors generally cost more than standard uPVC options, they offer greater value over time. Their durability, energy efficiency, and minimal maintenance help offset the higher upfront cost. Think of it as an investment in your home’s appearance, security, and comfort.
Whether you're upgrading your front entrance or looking to improve insulation and security, composite doors deliver across the board. Their combination of strength, beauty, and low maintenance makes them a standout choice for homeowners who value quality and design.
Explore the range of composite doors available from trusted suppliers and discover how a well-designed front door can transform your home, both in looks and performance. Feel free to view our complete range at www.plasticbuildingsupplies.com

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work” Jason Wright | ![]() |
