The Optimum range represents the ideal starting point for homeowners and architects seeking a bespoke-quality entrance door without compromise on specification.
Across 21 designs, the Optimum collection delivers refined exterior aesthetics, precise engineering, and excellent thermal and acoustic performance — all at a price point that makes genuinely high-quality entrance doors accessible. Each door is available across three profile systems: CarbonCore Aluminium for maximum durability and weather resistance; Aluminium Clad Timber, which combines a timber interior with an aluminium exterior for a warm internal aesthetic and low-maintenance outer face; and full Timber for those who prefer the character of natural wood throughout.
Every Optimum entrance door is engineered for airtight installation, with multi-point locking as standard and a choice of premium handle systems and glass specifications. The range spans a wide variety of designs — from clean contemporary flush formats to doors with defined panel sections and partial glazing — providing a versatile selection for different architectural contexts, from modern new builds to traditional residential elevations.

Choosing your entrance door is one of the most impactful decisions in any home project. The Optimum range was designed with precisely this in mind — offering enough design variety and specification depth to suit a wide range of architectural styles, while maintaining the manufacturing consistency and quality control that defines the Zakuna product programme.
Whether you are replacing an existing front door, specifying for a new build, or sourcing doors for a development project, the Optimum range delivers with confidence.
All Optimum entrance doors are available in an extensive range of RAL and bespoke colour options, with the ability to specify different exterior and interior colours — a particularly useful feature when the door connects a coloured exterior with a neutral internal hallway. Hardware options include a comprehensive selection of handles, locks, and smart access systems.
