Preparation
We highly recommend to use a hot knife or hot wire cutters, however, you can still use a standard knife or saw.
EPS Insulation Application
EPS insulation boards should always be installed in accordance with the manufacturer’s installation guidelines. This should cover design and all aspects of the application of the insulation. Initially, you can fix the EPS boards to the substrate (masonry or timber) by a mortar/adhesive or simply by mechanical fixings.
After fixing the board to an external wall, we recommend that you cover the boards with an outer layer. This can be either be the mortar basecoat or simply a netting covering to protect from excessive heat, moisture and UV exposure.
Before you apply the basecoat or mortar for the fibreglass mesh, you should rasp or sand down the top surface of the board to produce an abrasive surface. Once you’ve done this, the substrate is ready for the application of the fibreglass mesh. For further information, please download the full installation guide.
EPS Insulation Storage
Keep in a dry place, in the original packaging. Avoid excess heat or UV light exposure.
