EWI Pro Metal Hammer Fixings are used to secure insulation boards to a wide range of substrates. They are ideal for external wall insulation systems and help ensure a strong durable fixing.

These hammer fixings are suitable for concrete brick and other masonry substrates. If you are unsure about substrate strength it is recommended to carry out a pull test before installation.

They can be used with EPS XPS and Mineral Wool insulation boards making them suitable for most EWI applications.

Yes the fixings feature a plastic-coated metal pin which helps limit thermal bridging and maintain consistent thermal performance across the insulation system.

A recess allows the fixing head to sit flush within the insulation layer. This ensures a smooth surface for basecoat application and avoids surface irregularities.

• Drill a perpendicular hole and clear debris

• Create a countersink recess

• Insert the fixing so the plate sits level with the insulation

• Hammer in the pin

• Insert a thermo dowel cap

• Check the fixing is secure and sealed

Quantities depend on the project design and wind load requirements. A typical EWI installation uses between 6 and 8 fixings per square metre but always follow system specifications or engineer guidance.

Yes these fixings are designed for use with EWI and ETICS systems and provide strong reliable anchoring in approved substrates.

You only need a drill appropriate drill bit and a hammer. A router or insulation cutter is required to create the recess for flush installation.
