What Are Composite Doors?

Unlike traditional doors made from a single material (like timber or uPVC), a composite door is engineered using a combination of high-performance materials. Not only that, but those materials are selected specifically for their unique strengths. Indeed, this multi-layered construction results in a door that is stronger, more durable, and more efficient than its counterparts.

The anatomy of our composite doors typically includes:

  • Solid Core: At the heart of the door is a robust core, often made from high-density polyurethane foam or a laminated solid timber. This provides exceptional strength and acts as a powerful thermal and acoustic insulator.
  • GRP Skin (Glass Reinforced Plastic): The outer layers are made from GRP, the same material used to make the hulls of boats. This skin is incredibly tough, durable, and resistant to dents, scratches, and warping. It features a realistic woodgrain effect or a smooth modern finish that won’t fade, crack, or peel.
  • Reinforced Frame: The door slab is housed within a steel-reinforced, multi-chambered uPVC outer frame, ensuring a perfect, weatherproof seal and maximum structural integrity.

Furthermore, this intelligent “sandwich” of materials creates a door that offers the stunning appearance of timber without any of its drawbacks.

Why Choose Our Composite Doors?

Invest in a Door That Delivers More

Choosing a composite door from Multitrades Windows & Doors is an investment in your home’s comfort, security, and value.

  • Unrivalled Security: With a rigid solid core, a high-impact GRP skin, and advanced multi-point locking systems as standard, our doors are built to deter and withstand potential intruders. We prioritise your family’s safety above all else.
  • Exceptional Thermal Efficiency: The high-density insulating core significantly reduces heat loss, keeping your home warmer in the winter and cooler in the summer. This helps to lower your energy bills and reduce your carbon footprint. Our doors can achieve impressive U-values, meeting and exceeding building regulations.
  • Superior Durability & Weather Resistance: Engineered to withstand the worst of the British weather, our composite doors will never warp, twist, bow, or rot. The waterproof GRP skin ensures your door remains pristine through rain, wind, and sun.
  • Effortless Maintenance: Say goodbye to endless sanding, painting, and varnishing. A composite door simply requires an occasional wipe with a damp cloth to keep it looking brand new for years to come.
  • Stunning Aesthetics: From timeless traditional designs that replicate classic timber doors to sleek, contemporary styles for the modern home, we offer a design to suit every taste.
  • Excellent Sound Insulation: The dense core and airtight seals dramatically reduce the amount of external noise entering your home, creating a more peaceful and tranquil living environment.
