For more than three decades, French manufacturer Minco has pursued a clear idea: a window should provide more than insulation, light and protection. It should also contribute to a healthier, more durable and increasingly circular approach to architecture.

Founded in 1990 and based in Aigrefeuille-sur-Maine, in western France, Minco specialises exclusively in hybrid joinery combining timber on the inside with aluminium on the outside.

The concept brings together two materials with distinct qualities. Internally, timber introduces warmth, natural character and strong thermal and acoustic performance. Externally, aluminium protects the structure from weathering, reduces maintenance requirements and provides extensive freedom in colour and architectural expression.

This combination has become the foundation of a broad product portfolio covering windows, entrance doors, sliding systems, pocket doors, curtain walls and certified passive-house solutions.

Minco manufactures around 120,000 units each year from approximately 33,000 square metres of production space. Its products are distributed throughout France through a network of around 1,500 professional installers.

Yet the company’s identity is defined less by scale than by the environmental principles guiding its product development.

Minco says its joinery is designed for complete disassembly at the end of its service life, allowing materials to be separated and recovered. The company also reports that 97 per cent of its production waste is reused or recycled, while the timber used in its conventional ranges originates in France and is PEFC certified.

In recent years, this strategy has moved beyond responsible sourcing towards material innovation.

The Recowood programme transforms timber recovered from building deconstruction into new engineered components for hybrid windows. A separate initiative, known as Fenêtre Reflet, uses aluminium offcuts to manufacture exterior frames, reducing the demand for new material.

Perhaps the most distinctive development is the Fenêtre Végétale, an eco-designed hybrid window using bamboo. Introduced as an alternative renewable material, bamboo has now been extended into Minco’s entrance-door collection, with 53 models available in the material for 2026.

The company has also integrated lower-carbon Oraé glazing across its standard window production, while launching services intended to extend the useful life of installed products rather than simply replacing them.

These developments reflect a broader shift within the construction industry. Environmental performance is increasingly being assessed not only through energy efficiency during use, but across the entire life cycle of a product — from material extraction and manufacturing to repair, reuse and eventual recycling.

Minco’s approach places the window within this wider debate.

Its hybrid systems can achieve thermal performance suitable for highly energy-efficient and Passivhaus projects, but technical figures form only part of the proposition. The company is also examining how products can store carbon, preserve resources, support biodiversity and remain serviceable for longer.

This is industrial manufacturing, but with an increasingly regenerative ambition.

For architects and construction professionals, the result is a product positioned between natural materiality and contemporary engineering. Timber remains visible where it contributes most to interior comfort, while aluminium provides resilience and architectural versatility on the façade.

More than 30 years after producing its first wood-aluminium windows, Minco is no longer simply promoting a hybrid material combination.

It is presenting a wider argument for how tomorrow’s building components should be designed: efficient in use, carefully sourced, repairable over time and recoverable at the end of their life.
