Maperend render system awarded BBA Certification

Mapei has now received BBA Certification for its Maperend render system. 

Maperend is a thin coat render for use as a ventilated and drained exterior wall system onto timber and steel-frame buildings, and is directly applied to Knauf Aquapanel Exterior Cement Board. During the BBA assessment process, key factors tested include mechanical resistance and stability, and safety in case of fire - the system is rated A2-s1,d0, in accordance with BS EN 13501-1 : 2018. This classification applies to the complete Maperend colour range.   

During the rigorous assessment process, the render system was tested across several key areas, including its safety, quality and compliance for use on external facades and its suitability for use in exposure zones up to and including the ‘severe’ wind-driven rain index category.

Mapei also holds BBA Certification for its Mapetherm EPS and Mapetherm EPS PLUS EWI systems.  All EWI systems, according to the BBA, also comply with NHBC Standards 2021.
