Single Doors

Customise your design with heritage-style single doors, featuring flexible transom and bar layouts. Whether you want a classic grid pattern or larger panes with fewer bars, we can tailor the sightlines and transom heights to suit your space and style.

French Doors

Our French door sets include a handle block on the primary leaf, finished with your choice of hardware. The secondary leaf can be configured with or without a matching handle — giving you full control over symmetry, function, and finish.

Configurations & Side Panels

Our aluminium external doors can be paired with matching side panels, toplights, or fixed frames to suit larger openings. This modular approach allows you to create full-width glazed façades or balanced doorways that retain character while enhancing natural light and garden views.

For added functionality, you can also incorporate opening window sashes into the side panels — ideal for natural ventilation in kitchen diners, garden rooms, or heritage refurbishments.

External Doors for Internal Use

Our external steel-look doors aren’t just for patios and garden rooms — they can also be installed inside your home to create stunning room dividers or feature entrances. If you’re happy with either a 3 cm standard threshold or 15 mm low threshold, this option opens up a world of design possibilities.

By choosing an external-grade system indoors, you’ll enjoy:

Superior acoustic performance – double glazing helps reduce noise transfer between rooms.

Full functionality – including the option for working lever handles on the slave door.

Industrial elegance – slim aluminium sightlines with a timeless steel-look finish.

However, if you prefer purpose-built internal doors with ultra-slim thresholds, you can view our dedicated Internal Doors range here.

Features

Part M Threshold

For added accessibility, our 33mm outer frame is available with a 15mm low threshold. Meeting Part M regulations, this option provides easy of entry for those who require it.

Ramps can be included inside and out for ramped access.

Polyamide Thermal Break

Our thermal break technology provides enhanced thermal performance, ensuring your home is thermally efficient all year round.

Combined with high performance glass, our range of doors meet the latest DOC L building requirements.

All master doors come equipped with secure, multi-point locking tested to the latest safety standards.
