Why Choose BS EN 17990:2025?

In the modern world, energy efficiency is not just a trend but a necessity. Buildings that are well-insulated and energy-efficient contribute significantly to reducing carbon footprints and lowering energy costs. The BS EN 17990:2025 standard is an invaluable resource for architects, engineers, and construction professionals who aim to design and build structures that meet the highest standards of energy efficiency.

This standard ensures that the materials used for creating airtight layers are tested for durability under conditions that mimic real-life indoor environments. This means that the adhesive tapes and masses you choose will perform reliably, maintaining the integrity of the building's thermal insulation over time.

Benefits of Compliance

Adhering to the BS EN 17990:2025 standard offers numerous benefits:

• Enhanced Energy Efficiency: By ensuring airtight layers, buildings can significantly reduce energy loss, leading to lower heating and cooling costs.
• Improved Indoor Air Quality: Airtight layers prevent unwanted air infiltration, which can carry pollutants and allergens into the building.
• Long-term Durability: The standard tests the longevity of adhesive materials, ensuring that they maintain their performance over time.
• Environmental Responsibility: By reducing energy consumption, buildings contribute to a more sustainable future.

Who Should Use This Standard?

The BS EN 17990:2025 is ideal for a wide range of professionals in the building and construction industry, including:

• Architects and Designers
• Construction Engineers
• Building Inspectors
• Energy Consultants
• Facility Managers

Conclusion

Investing in the BS EN 17990:2025 standard is a step towards ensuring that your building projects meet the highest standards of thermal insulation and energy efficiency. By following this standard, you are not only enhancing the performance and sustainability of your buildings but also contributing to a greener planet.

Stay ahead in the industry by integrating the principles of the BS EN 17990:2025 into your projects. Ensure that your buildings are not only compliant but also exemplary in their energy efficiency and environmental impact.

BS EN 17990:2025

This standard BS EN 17990:2025 Thermal insulation and energy economy in buildings. Method to determine the durability of bondings with adhesive tapes and adhesive masses for the establishment of airtight layers under climatic conditions representative for indoor environments is classified in these ICS categories:

• 91.120.10 Thermal insulation of buildings

This document specifies methods to determine the durability of bondings, prepared by means of adhesive materials (e.g. adhesive tapes and adhesive masses), for the establishment of airtight layers under climatic conditions representative for indoor environments based on test methods with and without ageing. The methods provided in this document require at least 120 days for aging and are therefore not suitable for a short time evaluation nor can they be applied to in-field testing. This document excludes test methods for external weathering or UV exposure, even though this might occur during the construction phase. The following typical applications are distinguished: - bonding of the overlap of flexible airtightness layers; - bonding of flexible airtightness layers to construction products and penetrations; - establishment of airtightness layers by means of sheet materials and adhesive tapes. This document does not apply to test methods for: - pre-compressed sealing tapes and sealing profiles which will be mechanically secured; - butyl-based adhesive tapes or adhesive masses; - sheet joints of wood-based panels or gypsum plasterboards with adhesive masses or filler systems; - bondings of bitumen membranes or of bitumen membranes to construction products; - bonding of self-adhesive membranes; - adhesive masses from reels. Adhesive masses from reels are cured viscoelastic adhesive masses, which are used in the same field of application as adhesive masses. The tack is not addressed. It does not allow any conclusion on the durability of a bonding.
