About XPS Insulation
Extruded Polystyrene XPS is a modern insulating material with fantastic thermal properties, good moisture resistance and high strength. This extruded polystyrene (XPS) board is a high density board that can be used for various applications on buildings, including DPC insulation, extending concrete windowsills or providing insulation backing where EPS is not suitable to use. The material has a smooth closed-cell surface ready for use.
These XPS boards can be used on timber, masonry and system build properties, as well as for tile hanging and as the base for a wide range of rendering systems.
- Reduces the risk of water penetration
- Compact and robust

Preparation for XPS Insulation
Use a protection mat to prepare the property before applying the insulation to the DPC.
Try to use a hot knife or hot wire cutters to minimise mess.
Application of XPS Insulation
The XPS insulation boards should be installed in accordance with a project plan or a brief prepared by the architect. The boards – if being applied to the area below the DPC or attached to the substrate – should be glued on with a quick drying mortar or adhesive (see EWI-225 Premium Basecoat).
After having been fixed to the area below the DPC or on the sills (when left to dry), the work area should be covered sufficiently to prevent water penetration or exposure to UV light.
When set and ready, apply the basecoat or mortar ready to sink into the fibre glass mesh. Once this has been installed, the substrate is ready for the application of the top coat.
Clean-up of XPS Insulation
Easy to sweep up or hoover.
