External wall insulation is a system: adhesive, board, reinforcing layer and finish. The adhesive and the render are often the same product, used in a different mix, and the glass-fibre mesh makes the layer strong enough to take movement.
The substrate decides the fixing: masonry and concrete carry the boards on adhesive, while a weaker or uneven wall needs mechanical plugs as well. Always finish with a render that is made for exterior use, so the facade stays water-repellent.
