ZILTEN: French manufacturer of exterior joinery

A brand born from a culture dedicated to the front door

Founded in 2005 in Corrèze, Zilten immediately positioned itself in a clear niche: offering entrance doors with a distinctive style. Initially focused on aluminum, the brand developed a strong aesthetic identity, based on contemporary lines and meticulous finishes.

In 2007, Zilten joined the CETIH group, a French industrial specialist in building envelopes and energy solutions. This integration provided it with a structuring industrial and technological foundation , while preserving its core identity: remaining an expert in entrance doors, without diversifying into all other joinery products.

"Our mission is to make the front door a fully-fledged architectural element."

Over the years, the product range has expanded to include steel, wood, and then PVC. Zilten now covers five materials, in line with the needs of single-family homes, both for new construction and renovation. This evolution is a continuation of CETIH's expertise, which boasts over 50 years of experience in joinery and innovation in entrance doors.

CONSULT THE STRATEGIC FILE

A multi-material range to meet the needs of every project

The Zilten catalog features over 200 models. The collections are available in contemporary, traditional, or fully customized versions. The goal: to meet the diverse architectural styles and technical constraints of construction projects.

Aluminium: performance and modernity

Aluminum plays a central role in the brand's DNA. Lightweight and strong, it allows for clean lines and large glazed surfaces. Aluminum doors benefit from advanced technical designs, with a focus on thermal insulation , dimensional stability , and durability.

Steel: robustness and insulation

Steel doors, available in standard or custom sizes, are fully customizable. Colors, glazing, hardware, accessories: every element can be adjusted.

These models offer good performance in thermal and acoustic insulation , meeting the challenges of comfort and reducing energy consumption.

"The front door must protect against both cold and noise, while also reflecting the style of the home."

Wood and PVC: modularity and eco-design

The wood and PVC ranges emphasize modularity. Bending, moldings, decorative glazing, finishes: the possibilities for adaptation are numerous.

Some wood collections, such as Nativ, exemplify an eco-conscious approach, combining aesthetics with attention to environmental impact. Wood brings a warm and authentic dimension, suitable for traditional or heritage projects.

Aluminum/wood composite: the technical compromise

Hybrid models combine the advantages of both materials. Aluminum provides protection on the exterior, while wood structures the interior. This solution aims to reconcile performance, durability and ease of use.
 

Design as a signature

At Zilten, design is not just a marketing ploy. It structures the brand promise. The models are distinguished by graphic glazing, sophisticated textures, and a wide range of colors.

The front door thus becomes an element that enhances the facade . It contributes to the architectural identity of the dwelling. Solid, semi-glazed, or fully glazed, each configuration integrates into a comprehensive design.

Customization goes beyond aesthetics. Choosing the security level, glazing type, and accessories allows the door to be adapted to the site's constraints. Adding fixed side panels or transoms further expands the design possibilities.

"Choosing a front door is as much about pleasure as it is about functional need."

Innovation and performance at the heart of the strategy

Integration into the CETIH group strengthens the innovation dynamic. Several milestones mark this trajectory:

• post-formed steel door since the 1990s;

• concept of a one-piece aluminum opening in 1995;

• steps to measure the environmental impact of doors from 2009 onwards;

• creation of the Nativ door in 2010;

• launch of the UNIK personalisation concept for wooden doors in 2017.

These developments reflect a continuous search for added technical and environmental value . The targeted performance levels cover thermal insulation, acoustic attenuation, safety, and durability.

A high-performance front door limits heat loss. It helps improve interior comfort and control energy consumption. It is also a strategic point in terms of security.
 

A partner in new construction and renovation projects

Zilten primarily targets single-family homes. The solutions offered adapt to existing dimensions in renovation projects or to specific configurations in new construction.

The brand positions itself as a partner to installers, tradespeople, and specialist distributors. The breadth of the product range makes it easy to meet the constraints of each construction site: atypical dimensions, required performance levels, architectural style, or budget.

In the ecosystem of building and housingThe front door occupies a strategic position. It constitutes a thermal interface, a security element, and an aesthetic marker.
 

An entrance that has become an identity marker

With more than 200 models and five materials, Zilten occupies a specific position: that of a manufacturer focused on the front door as an architectural object.

The combination of design, personalization, and performance meets the current expectations of building owners and professionals. In a context where the quality of the building envelope influences comfort and energy efficiency, the front door becomes a strategic choice.

At the crossroads of aesthetics and technology, Zilten offers a rich field of expression for designing a protective, durable entrance that is consistent with the identity of each home.
