Sistemas Técnicos del Accesorio y Componentes (STAC) is a leading Spanish company in the design, development, and manufacture of technical solutions for architectural enclosures. With more than 500 professionals and a consolidated presence in over 80 countries, the company combines innovation, quality, and sustainability across all its processes.

*STAC uses a wide variety of technical materials in the design and manufacture of its solutions*

Production centres are located in Padrón and Catoira (Spain), with more than 72,000 m2 of facilities where all phases of design and production are carried out. These plants manufacture hardware and accessories, polyamide and PVC insulating profiles, EPDM gaskets, and a wide range of thermoplastics.

By bringing together these product ranges, STAC has become one of the few companies in Spain capable of acting as a comprehensive supplier for any systems integrator. The company also operates its own lacquering facilities and has an internal department specialising in moulds and machinery, enabling complete control over the entire manufacturing chain and ensuring maximum quality at every stage.

For sealing gaskets, STAC employs EPDM with high resistance to weather, ozone, and deformation, along with other thermoplastics tailored to specific applications

STAC uses a wide variety of technical materials in the design and manufacture of its solutions. In the field of insulating profiles, it primarily uses polyamide (PA66) reinforced with 25% fibreglass, as well as recycled versions of this material (PA66-25GF RE), which significantly reduce environmental impact. For sealing gaskets, STAC employs EPDM with high resistance to weather, ozone, and deformation, along with other thermoplastics tailored to specific applications. Hardware and accessories are manufactured from materials such as zamak, aluminium, technical polymers, and stainless steel, ensuring strength and durability.

With more than 20 years of experience, the company offers comprehensive technical services, supporting architects, engineers, and builders through every stage of a project – from defining tailor-made solutions to on-site advice, material optimisation, specialist training, and after-sales support.

Its innovative spirit is reflected in the development of products that combine high technical performance – strength, durability, insulation, and low maintenance – with a flexible aesthetic approach, offering a wide range of finishes and customisation options.

In terms of sustainability, STAC promotes circular economy and carbon footprint reduction initiatives through the use of recycled materials, efficient industrial waste management systems, and environmental certifications that ensure minimal environmental impact.

*Headquartered in Padrón, Spain, STAC has always maintained a global vision*

These certifications, validated by independent organisations such as Bureau Veritas, demonstrate the company’s commitment to excellence, transparency, and environmental responsibility:

ISO 9001:2015 – Guarantees a quality management model focused on continuous improvement, process control, internal audits, and customer satisfaction.
ISO 14001:2015 – Ensures efficient environmental management committed to protecting the environment.
ISO 14021:2016 – Confirms that the RE and RE+ range products contain a minimum percentage of recycled material, verified by Bureau Veritas.
Environmental Product Declaration (EPD) – Available for HITEP and PA66 thermal break profiles with 25% fibreglass. These EPDs, Type III according to ISO 14025, assess the entire life cycle of the product and are registered in the International EPD System.
Cradle to Cradle – Certifies that products are safe, circular, and responsibly designed across all stages of their life cycle.
EcoVadis (Committed Label) – Recognises strong sustainability management based on environmental, social, and ethical criteria.

Headquartered in Padrón, Spain, STAC has always maintained a global vision. It operates subsidiaries and offices in Portugal, Morocco, Poland, Türkiye, Mexico, and the United States, thereby strengthening its international distribution and service network.

The company also actively participates in major international trade fairs, showcasing its full potential at events such as The Big 5 (Saudi Arabia), Fensterbau (Germany), Batimat (France), Eurasia Window Fair (Turkey), and BAU (Germany).

STAC’s extensive experience and technical expertise have enabled it to contribute to landmark architectural projects worldwide, reinforcing its position as a trusted strategic partner in delivering solutions for modern architecture.
