Introduction Sto-Rotofix Plus Sto-Rotofix Plus is an innovative fixing system for mechanically fixed external wall insulation systems onto masonry and cement particle board substrates. The Sto-Rotofix Plus system can be used with tongue-and-groove EPS boards or square-edged mineral fibre insulation boards. The Sto-Rotofix Plus unit combines the ease-of-use associated with ETICS anchors with the flexibility of a rail system. Features & Benefits • Provides a cavity behind the insulation board. Easily overcomes irregular or out of tolerance backgrounds. • Allows for post-installation...

Introduction General EWI installation advice Check the state of the substrate precisely and then select the appropriate fixing system for the external wall insulation system. The substrate must be pre-treated as appropriate to the system. Measure the correct temperature and given building moisture before application. The lowest temperature allowed for the application of most Sto products is 5°C. Sto QS products are available for winter working to a minimum application temperature of 1°C. • • • • • • • Before work begins, doors, windows, shutter boxes and horizontal covers (e.g. window...

Insertion of Sto-Rotofix Plus spiral plug into insulation Create a recess in the insulation For EPS insulation over 100mm thickness, we recommend using a countersink milling tool to create a recess in the insulation. For mineral fibre board (MFB), a recess is only recommended post-installation if the Drill a hole through the insulation Using the green jolley tool, drill a hole through the insulation board. This helps to reduce debris behind the cavity, which is especially important for MFB installation. Screw Sto-Rotofix spiral plug into Ensure the drill hole is free of debris, then screw...

Drilling into substrate Drill hole into substrate Using the correct drill bit, drill a hole into the substrate through the hole in the Sto- Rotofix Plus spiral plug. Use a drill stop to While the drill bit is turning, ventilate the hole several times. For cement particle board: Using a suitable drill with a 10mm HSS drill bit (without hammer action), drill through Use suitable drill with a 10mm hammer drill bit to suit length. Do not use the hammer drill function on hollow brick/block. For E1/E100 fixing into existing render: Allow 70mm into sound substrate + render The technical...

Placing the screw dowel Insert screw dowel Insert the appropriate screw dowel fixing into the plug by hand. Ensure the fixing is correctly placed using the appropriate Sto-Rotofix Plus positioning tool. If required, a hammer can be used on the Grey positioning tool For 120T/160T fixing into cement particle board and unrendered masonry. For EVE 100 fixing into rendered masonry or aerated concrete. Positioning tools The technical specifications and information on the products in the technical data sheets and approvals must be observed.

Fixing Sto-Rotofix Plus Screw fixing Screw and secure the fixing into the substrate using a suitable power screwdriver/drill with the Sto-Rotofix Plus Jolley tool. Do not secure the fixing if the wall The technical specifications and information on the products n the technical data sheets and approvals must be observed

Adjusting Sto-Rotofix Plus Align the insulation as required for the project using string lines. Max. 30mm with the Sto-Rotofix Plus green plug or max. 70mm with the Sto-Rotofix Plus black plug. We recommend that once insulation thickness exceeds 140mm, the Sto-Rotofix Plus black spiral plug should be used. Use square end of positioning tool (grey or red) to adjust fixing in/out. The technical specifications and information on the products in the technical data sheets and approvals must be observed.

Installation Finishing 8a Fill the recess For EPS insulation over 100mm, the recess gap can be filled using a Sto-Thermocap EPS pushed into place. For MFB insulation, where the recess is not normally formed, the gap behind the fixing can be filled with MFB offcuts or PU foam. For EPS/MFB 80/90mm, do not recess. Use PU foam to rectify minor holes generated by fixing/placement of Sto-Rotofix Plus units. 8b The technical specifications and information on the products in the technical data sheets and approvals must be observed.
