Insulating panels are fixed to the wall using adhesive mortar.

Plastic capped fixings are driven through the insulating panels and around their perimeter into the wall to tie the panels securely to the wall.

Mortar is then applied over the insulating panels and the fixings.

An insulating mesh is then sunk into the mortar to hold the panels in position.

The mortar is sanded and painted with primer to prepare it for the render

The render finish is applied (available in any colour).
