A1 Non-Combustible EWI Systems
Introducing breakthrough EWI systems achieving an A1 non-combustible fire rating.
An A1 rated fireproof insulation solution in the UK for building facades, exclusively available from Wetherby. The A1 System range sets new standards in external wall insulation fire performance.
The render system options are finished with Wetherby Heck ED Mineral Render finishing coat, which is ideal for use with stone wool insulation, providing great breathability. While the brick slip systems offer a durable real clay brick finish in a wide range of colour options.
To achieve an A1 rating, the system must be classified to EN 13501-1 using the following fire tests.
- EN 13823 SBI (Single Burning Item) – Used to determine the reaction to fire by exposing a flame to the system finish.
- EN ISO 1716:2010 – Bomb test. Each component of the system is ‘blown up’ to measure heat output (calorific value). All components must be A1.
- EN 1182 – xxxxx
