In the aftermath of the Grenfell Tower tragedy in 2017, the construction industry has faced increased scrutiny regarding fire safety, particularly concerning external wall systems and cladding materials. A pivotal development in this area is the External Wall System (EWS1) form, introduced to assess and certify the fire safety of a building’s external components.
Understanding the EWS1 Form
The EWS1 form was developed to provide a standardized method for evaluating the fire risk associated with a building’s external wall system, including cladding, insulation, and attachments like balconies. While not a legal requirement, many mortgage lenders mandate an EWS1 assessment for properties, especially those exceeding 18 meters in height or featuring specific cladding materials, before approving loans.
The assessment categorizes buildings based on the combustibility of materials used:
- Option A: External wall materials are unlikely to support combustion.
- Option B: Combustible materials are present in the external wall system.
Each option has subcategories that further define the level of risk and the necessity for remedial actions.
The Role of Non-Combustible Materials in Compliance
In response to the heightened focus on fire safety, the use of non-combustible materials in construction has become paramount. Materials classified as A1 or A2 under the Euroclass system are considered non-combustible and are preferred for use in external wall systems to mitigate fire risks. For instance, in decking applications, materials such as aluminium and porcelain products offer non-combustible solutions. Aluminium decking provides a durable and fire-resistant option suitable for balconies and terraces. Similarly, our Vitrified Composite® is a wood effect decking system for waterproofed substrates, achieve A1 fire ratings, ensuring compliance with the latest fire safety regulations.
Challenges and Considerations
Despite the clear benefits of non-combustible materials, the industry faces challenges in implementation. The demand for EWS1 assessments has led to delays in property transactions, as qualified professionals are required to conduct these evaluations. Additionally, the discovery of fraudulent activities by some fire safety firms has further complicated the process, leading to increased scrutiny and the need for re-assessments in certain cases.
Conclusion
The introduction of the EWS1 form underscores the critical importance of fire safety in building design and material selection. For paving and decking companies specializing in non-combustible materials, this presents an opportunity to contribute to safer building practices and ensure compliance with evolving regulations. By staying informed about the latest developments in fire safety assessments and embracing the use of non-combustible materials, companies can play a vital role in enhancing the safety and resilience of modern constructions.
