Thin Coat Render Corner Bead
This is the most popular type of bead when installing thin coat render systems. The corner bead consists of a rigid PVC 90-degree angle, with two ‘wings’ of fibreglass mesh (100mm and 150mm).
The corner bead gets embedded on all external corners of a render only or external wall insulation system within the cementitious basecoat layer.
The purpose of the corner bead is twofold, firstly it helps provide nice accurate 90-degree corners on a building. The thin coat corner bead also helps protect the corner against impact damage.
The corner bead is 2.5m in length. It is completely embedded within the basecoat layer, so unlike monocouche corner bead, will not be visible once the render system has been finished.
The corner bead with mesh is also often used around windows and doors to strengthen that area.
