CSTB QB for window profiles

From 2022, the Xelter product line of the Sirmax Group, a leading manufacturer of high performance thermoplastic compounds, will be certified by CSTB QB. This production line is dedicated to window profiles for the Building & Construction sector. This important recognition confirms the quality and reliability of our materials, guaranteeing superior performance in the construction sector, with particular emphasis on safety, durability and efficiency

CSTB QB certification is a quality mark issued by the Centre Scientifique et Technique du Bâtiment (CSTB), an internationally recognised body for the evaluation of materials for the construction industry. QB certification is specifically aimed at materials and components used in applications such as windows, doors and facades, and attests to their compliance with European standards in terms of safety, performance and reliability.

For Sirmax, the CSTB QB certification for the Xelter S line of window profiles is a validation of our commitment to producing materials of the highest quality, perfectly suited to ensure maximum performance even in extreme environments, and confirms our leadership in the field of thermoplastic compounds for the construction industry.

With the CSTB QB certification, the line of Xelter S thermoplastic elastomers for window profiles has passed all physical and chemical tests, ensuring high performance for key building industry requirements, including:

• Thermal and acoustic insulation: these materials are designed to provide excellent thermal insulation, improving the energy efficiency of buildings and reducing their consumption. Advanced acoustic insulation provides greater living comfort by reducing external noise.

• High temperature resistance: the aim is to maintain structural integrity even in high temperature environments, ensuring consistent performance over time, whether in intense heat or extreme cold.

• Durability and stability: The materials used in the Xelter S range are designed to resist ageing, mechanical stress and the most severe weather conditions, ensuring a long product life.

• Fire safety: CSTB QB certified window profiles meet strict safety standards, helping to protect buildings in the event of fire and reducing the risk to occupants.

CSTB QB certification confirms Sirmax's position as a benchmark for innovation in the plastics industry.

Window profiles made from Xelter S material are used in a wide range of applications, including residential, commercial and industrial buildings, due to their superior properties in terms of insulation, durability and safety. The company's ongoing commitment to research and development enables it to offer state-of-the-art solutions to meet the needs of a market increasingly focused on energy efficiency, safety and sustainability.

The Xelter S TPE family is not only synonymous with high performance. Sirmax sees sustainability as a pillar of its value proposition and is committed to producing materials with a low environmental impact. Xelter S uses technologies that promote recycling and resource efficiency. This helps to create more sustainable buildings with a lower environmental impact. The result is safer, more efficient and greener buildings.
