Cembrit is pleased to announce that it we have received another approval from the British Board of Agrément (BBA) for our building board range Windstopper Extreme, providing peace of mind to specifiers who choose to use Cembrit’s non-combustible fibre cement sheathing boards on their projects.
What is certified?
This Agrément Certificate Product Sheet(1) relates to Windstopper Extreme, fibre-cement boards for use externally as sheathing boards to new and existing buildings, providing temporary weather protection prior to over-cladding with a permanent façade rainscreen cladding. The boards can be used structurally when applied to steel-frame substrate walls. The boards are non-structural when applied to timber-frame substrate walls, providing racking resistance where required.
