For trade installers, choosing the right composite door supplier can make a big difference to how smoothly a project runs. Reliable lead times, accurate specifications, competitive pricing and a good range of options all matter when you’re working to installation dates and customer expectations. 

At Boston Trade Frames, we’ve been manufacturing and supplying windows and doors since 1981. We provide supply-only composite doors directly to trade installers, with doors made to your client’s requirements and a choice of styles, colours, hardware and glazing options. Whether your customer is replacing traditional wooden doors, looking for a new front door or upgrading an existing entrance, we can help you find the right specification for the job. 

A composite door supplier built around trade needs

We know that every installation is different, which is why we offer a range of composite doors to suit different properties, budgets and customer requirements. 

We supply composite doors from established manufacturers including Solidor, DoorCo and Distinction, giving you access to different construction methods, colours, finishes and design options. This means you can offer your customers more choice without having to source different products from multiple suppliers. 

We can also help you work through the available specifications if you’re unsure which option is most suitable for your customer’s project. 

A wide range of composite doors

We understand that no two customers want exactly the same door. That’s why we offer a range of styles and specifications rather than a one-size-fits-all solution. 

Our composite door range includes products from Solidor, DoorCo and Distinction, giving you different options to discuss with your customers. 

Solidor doors feature a 48mm solid hardwood timber core, while DoorCo uses a high-density polyurethane foam core with a GRP outer skin. Distinction also uses a high-density PU foam core and GRP skin, alongside a range of finishes. 

This combination of materials gives you different options to consider depending on the project, whether your customer is looking for a traditional appearance, strong thermal performance or a modern finish.

Colours, internal finishes, glass and hardware

We know that personal taste plays a big part in choosing a new door, so we offer plenty of options to help you create the finished look your customer wants. 

Our composite doors are available in a wide range of colours and finishes, from timeless neutrals to bolder shades such as Chartwell Green. Woodgrain finishes can also complement the appearance of traditional wooden doors while providing the practical benefits of a modern composite door. 

We can also specify the internal colour of the door, with some ranges offering different colours inside and out. Solidor, for example, offers dual-colour inner and outer options, giving you more flexibility when matching the door to your customer’s property. 

We can also supply different hardware and glass designs to complete the look. Depending on the chosen range, options include handles, letterboxes and knockers alongside a variety of decorative glazing designs. 

Side panels can also be included as part of a made-to-measure specification, giving you more flexibility when designing a new entrance for your customer. 

Security features you can specify

Security is an important consideration when you’re installing a new composite front door, so we offer a range of security features depending on the manufacturer and specification. 

Our composite doors can include multi-point locking systems and high-security locking options, while some products can also be specified to meet recognised security standards such as PAS 24. 

For example, Solidor doors are compatible with Ultion 3-Star security cylinders and a range of smart lock systems. 

The exact security specification varies between products, so we can help you identify the appropriate options for your customer’s requirements before you place your order. 

Energy efficiency and composite door construction

Thermal performance is another important consideration when choosing a new composite door. 

We supply doors using different combinations of materials, depending on the manufacturer. Solidor uses a solid hardwood timber core, while DoorCo uses a high-density polyurethane foam core with a GRP outer skin. Distinction also uses a high-density PU foam core. 

These different construction methods can provide strong thermal efficiency alongside the durability and minimal maintenance expected from a modern composite door. 

If your customer wants to improve energy efficiency, reduce heat loss or potentially lower their energy consumption, we can talk you through the different options available. 

Turnaround times you can plan around

We understand that lead times matter when you’re arranging installation dates and coordinating other work on a project. 

Once you request a free quote and confirm your requirements, we aim to get back to you within 48 hours. Products can typically be delivered within 2–4 weeks of order confirmation, although the exact timeframe will depend on the product and specification. 

Because we supply doors to your client’s requirements, we’ll discuss the details with you before the order is confirmed. This gives you a clearer idea of the expected timeframe when planning your installation. 

Expert support before and after delivery

We believe good trade support should go beyond simply supplying the door. 

Our family-run team has extensive experience in the window and door industry, with owner and director Nigel Apps bringing decades of experience to the business. Nigel began his career as a joiner before moving into uPVC window manufacturing, giving us a strong understanding of the products and practical requirements involved. 

If you have a question about a product, specification or order, our team is available to help before and after delivery. We can also provide information about manufacturer warranties and help with queries relating to your supply-only order.
