Heritage-sensitive composite doors and timber-effect aluminium frames
Our heritage-sensitive composite doors are designed to maintain the charm of traditional Horncastle and surrounding conservation properties while offering all the benefits of modern materials. Timber-effect aluminium frames replicate the warmth and grain of real wood but without the ongoing maintenance. This makes them ideal for listed buildings or character homes looking to enhance energy efficiency and security while staying true to their architectural roots.
Homeowners can choose from a variety of authentic finishes, including oak, mahogany, and painted heritage tones. Each composite door is built for long-term performance, offering:
• Weather-resistant, warp-free construction
• Advanced insulation and thermal retention
• Multi-point locking systems for peace of mind
• Customisable glazing, panels, and hardware to match existing features

Timber-effect finishes that suit listed properties
Our composite doors feature authentic timber-effect finishes, offering a refined aesthetic suitable for listed and period homes. Using advanced surface texturing, these finishes replicate the look and feel of natural wood, allowing property owners to enjoy the visual appeal of timber with none of its upkeep demands.
Available in a variety of traditional colours and grain patterns, these finishes can be paired with decorative glazing, classic door furniture, and bespoke mouldings. The result is a truly bespoke entryway that blends harmoniously with any heritage façade while offering the performance of a modern composite system.
Secondary glazing-compatible options for conservation requirements
For listed and conservation properties where full frame replacement may be restricted, we offer secondary glazing-compatible composite door systems. These solutions provide enhanced energy efficiency and acoustic performance while retaining the original exterior appearance.
Our systems are designed to integrate seamlessly with existing openings and feature ultra-slim profiles for minimal visual impact. Combined with discreet aluminium framing and high-performance seals, they offer a practical and compliant option for improving comfort and efficiency in heritage homes without breaching planning conditions.
