Acoustic Testing

Ensatec’s experience in measuring noise and in defining the characteristics of all kinds of acoustic insulation elements guarantees suitable evaluation of designs for avoiding acoustic contamination.

ENSATEC holds ENAC accreditation Nº 288/LE652, according to the criteria expressed in UNE-EN ISO/IEC 17025 regulations for in situ testing in buildings.

It’s currently testing Laboratory aerial noise insulation testing of building components according to UNE-EN UNE-EN ISO 10140-2

As a body with solid experience in this field,ENSATEC played an active role in Technical Building Code acoustic research group (CTE-HR),within the regulatory framework of the Code Application Document for protection against noise (CTE-DAC-HR) and in communicating the implications the changes in regulations have had on the specifications on acoustic conditions in comparison with those of the previous regulations for buildings subject to the basic building code (NBE-CA88).

ENSATEC is a member of AECOR, Spanish Association of Acoustic Quality, a national technical non-profit association, comprising over 130 companies and professionals specializing in acoustics in building, industry or the workplace.

Thermal Testing

The Thermal Laboratory of ENSATEC, complements the services of the Enclosures Laboratory and Materials Laboratory, carrying out tests of

  • Thermal transmittance in a stationary system (Hot Box) of windows, frames, curtain wallings.
  • Thermal transmittance finite element simulation, of windows, doors, constructive elements, enclosures and curtain wallings.
  • Thermal conductivity of insulating materials

Thermal calculations made with the most up-to-date software and methods that allow you to perform a thorough thermal analysis in order to improve the performance of your product.

With extensive experience in the enclosure sector, the thermal laboratory service seeks to optimize the design of enclosures and accessories and achieve the maximum performance, required by the most demanding standards as PASSIVHAUS

Fire Testing

The ENSATEC facilities allow analysis of a material or system’s behaviour when tested for resistance and reaction to fire under its characteristic usage conditions.

European regulations, expressed through the specific regulations of member countries, defines the conditions the materials, systems and spaces must meet to guarantee users’ safety in the event of fire and which include several eventualities:

  • Propagation of the fire, both inside and outside the building.
  • Safe evacuation of the occupants.
  • Installation of detection, monitoring and extinguishing systems.
  • Fire-fighters intervention.
  • Structure fire-resistance.

The department specialises in testing construction materials‘ reaction to fire and the fire resistance of walls, doors and closure elements. ENSATEC is a member of AELAF (Spanish Association of Accredited Fire Laboratories) and a member of the Normalisation Technical Committee CTN-23.


The tests for determining fire resistance of walls and fire-doors are designed to check and test the requirements of solidity and insulation they must meet, as well as ensuring the functionality of the fire-doors self-closing mechanismswhich guarantee their safety.

  • Fire resistance tests for doors EN 1634-1, BS 470-20/22
  • Fire resistance tests for non-loadbearing elements.EN 1364-1, BS 470-20/22
  • Fire resistance tests for building hardware
  • Extension application reports (EXAP reports)


ENSATEC, accredited by ENAC, has a specialist fire department equipped with the most advanced installations adapted to meet the new European standards in construction materials (Euroclases).

  • Non-combustibility test
  • Single Burning Item Test (SBI).
  • Ignitabilty test. Single-flame source test
  • Radiant panel test
  • Determination of the gross heat of combustion
  • Extension application reports (EXAP reports)
