Front doors are the first impression of any property, making the specification of a composite door a critical part of any home improvement project.
A composite door combines different materials, such as GRP, timber, and insulating cores, to deliver strength, thermal efficiency, excellent insulation, and aesthetic appeal.
Whether it’s a new build, renovation, or replacing old windows, a well-specified door ensures your clients receive a perfect front door that meets their needs.
At Doncaster Trade Windows, we help trade customers confidently specify composite doors that maintain your reputation for high standards and great service.
How to confidently specify leading composite doors for client projects
Selecting the right composite door requires attention to material, style, and performance. Trade professionals can use these considerations to guarantee a finished product that impresses every client.
Material consistency
Ensuring consistent quality is essential for any project. Our composite door range is sourced from trusted suppliers like DoorCo and Distinction Doors, combining high quality materials and robust construction for long-lasting results.
A wide range of colour options
Colour can define the overall aesthetic of a property. We provide a vast range of colours, from timeless whites and creams to bold blues, greens, reds, and realistic woodgrain finishes. This flexibility allows trade customers to match existing windows, doors, or other features, creating a harmonious look for each project.
Door styles and glass options
Our range of composite doors offers styles to suit any property, from traditional Signature doors and stable doors, to the modern nxt-gen range. Glass options, including triple-glazed, decorative, and laminated designs, ensure your clients’ favourite door style complements the rest of the home while providing security and thermal efficiency.
Hardware quality
Multipoint locking systems, durable hinges, and corrosion-resistant handles provide security and reliability. Specifying doors with high-quality hardware gives trade professionals peace of mind, knowing their clients will enjoy a secure and dependable entrance.
Lead times
Fast, reliable lead times are critical to project schedules. We work closely with trade customers to ensure orders are processed efficiently, and we provide clear communication on expected delivery times. For homeowners requiring full installation, we offer flexible scheduling and keep you informed every step of the way, so your project can proceed without delays.
Thermal performance and energy efficiency
Our composite doors feature foam or timber cores and insulated components to reduce heat loss and maintain energy efficiency. Products like the Distinction GRP doors or DoorCo GRiPCORE series provide excellent insulation, helping clients reduce energy costs while keeping interiors comfortable year-round.
