The quality of ALUTECH systems is confirmed by DTA and QB French certificates

13-07-2021 news

In order to confirm the compliance of ALUTECH products to international standards, the Group regularly undergoes tests in accredited research centers in the CIS, Europe and the USA. We are pleased to announce that the high quality of ALUTECH aluminium profile systems has once again been confirmed by the authoritative European certification body such as CSTB, France.


The DTA (Document Technique d'Application) is a technical assessment of the suitability of specific products for the French market. This document allows the manufacturers of windows made of ALUTECH profiles to market the ALUTECH system in France without performing quality assurance tests that are quite expensive.

The first stage was the certification of ALUTECH ALT W62 window system with thermal break. The DTA certification for ALT W72 thermal insulation window system is planned for the future.

The DTA test program includes:

  • AEV test — air permeability, water resistance, wind load resistance,
  • mechanical wear resistance test — 10,000 opening and closing cycles (tilt and turn mechanism);
  • air permeability test with thermal shock cycles and deformation measurement at 75 °C.

Obtaining test reports is only one step in the complex DTA certification process. After passing the tests, a specialized group of experts representing different fields of activity (general customers, architects, design offices, technology controllers, contractors, research centers, laboratories, regulatory centers, etc.) reviews the company file (test reports, unit layouts) and decides on compliance with DTA requirements.

Therefore, the DTA certification opens new horizons for ALUTECH profile systems that have previously proven their worth in many projects on the French market.


QB is a mark of quality, performance and reliability of products and systems used in construction on the French market. The products with this mark possess technical specifications that have been certified by an independent and reputable organization (e.g. certification body CSTB or its partners).

AluminTechno first received QB certification in 2017. Now we announce that AluminTechno has successfully passed another QB certification audit. This entitles ALUTECH to display the QB logo on aluminium profiles in the future.

QB certification process involves the following steps:

  • providing a profile file,
  • test program elaboration,
  • selection of representative samples to be tested,
  • testing of products in accredited laboratories,
  • production audit,
  • conformity certificate issuance,
  • annual audit.

After successfully passing the tests and audits, manufacturers are authorized to display QB logo on products, packaging and in marketing materials. Periodic audits and monitoring of the manufacturer are then carried out.

We are certain that the DTA certification and the renewal of the QB certificate prove that the quality of ALUTECH profile systems meets the strict requirements of the French market and open up even more opportunities for both the holding and its partners.
