General information Basic information on installation of an external wall insulation system. 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 in the appropriate manner. Observe the correct application temperature and the given building moisture. The lowest application temperature (with the exception of Sto QS products) is 5°C. • Doors, windows, shutter boxes and horizontal covers (e.g. window sills) must be in place before beginning sealing work. • The required materials are to be...

General information Sto-Turbofix: PL) foam bonding adhesive for the StoTherm Classic external wall insulation system, incorporating tongue and groove insulation boards. • Simple, compact equipment • Rapid preparation time • Good adhesion on virtually all substrates • Light insulating boards for bonding purposes (mass/weight of • Initial set at 10-15 minutes. Over-coatable after only 2 hours • Saves space on the site and scaffolding during storage and • No cleaning of mixing machinery Sto-Turbofix accessories • Flexible 1.5m hose with angle piece and valve • Safety goggles • Gloves, overalls &...

Insulant Insulating boards as tongue and groove system Using insulating boards with a tongue and groove detail minimises the finishing work on the installed surfaces through rasping. This detail reduces post expansion of the PU adhesive. (e.g. grinding notches on insulating boards). Tip Protect polystyrene rigid foam boards from UV radiation and damp. Do not use damp or wet insulating boards. Bonding of insulating boards Adhesion problems may occur if the polyurethane bonding foam is left exposed for too long on the board. The boards should be pressed onto the substrate immediately after applying...

Assembly of the Sto-Turbofix system Connect Sto-Turbofix cylinder and Screw Sto-Turbofix hose loosely onto the Turbofix cylinder, then turn the corner valve to the side and tighten with a spanner, taking care not to overtighten the nut. After connecting the components, fix the hose to the handle with a cable tie. Lock foam gun in safe mode Before screwing the hose and the foam gun to the cylinder, the foam gun must be locked in safe mode. To do this, turn back the adjusting screw on the rear of the foam The technical specifications and information on the products n the technical data sheets and...

Preparation Assembly of the Sto-Turbofix system 3 Connect hose to gun Fix hose by hand to the underside of the foam gun. Then tighten with a spanner, taking care not to overtighten the connection. Safety information The cylinder is pressurised. If it is handled incorrectly or damaged, foam may issue from the cylinder in an uncontrolled manner, soiling objects and persons in the surrounding area. The following rules on handling the cylinder should therefore be observed: 1. Do not jerk the hose connected to the cylinder. Under no circumstance should the cylinder be lifted or carried by the hose....

Preparing the Sto-Turbofix system Sto-Turbofix should be shaken from time to time in the course of application, in order to control consumption. This will also keep the foam quality constant. Open cylinder and foam gun Open the yellow valve on the top of the Sto-Turbofix cylinder slowly, checking the area of the Sto-Turbofix connection for Before commencing application, turn the adjusting screw for controlling the pressure on the rear of the foam gun slowly forwards (adjusting as necessary during application). The technical specifications and information on the products n the technical data sheets...

Fixing the insulating boards Applying PL) bonding foam to the insulating boards Apply a bead of bonding foam all around the edge of the boards, enclosing additional • Bonded proportion of board (contact surface area) > 40 % • Keep the foam as close as possible Installing the insulating boards Install insulating boards from the bottom upwards with tight butted joints, setting them back at the corners of the building. Note: The insulating boards must not be knocked against the wall The technical specifications and information on the products n the technical data sheets and approvals must be observed...

Fixing the insulating boards Even surface, adjustment An even insulating board surface is achieved by using tongue and groove insulating boards and adjusting the position of the boarding by pressing briefly within the workable time (10 minutes). In order to avoid subsequent expansion during interruptions in the installation process (e.g. breaks in work), the installed insulating boards should either be fixed in position by mechanical means or adjusted a spirit level after approx. 10 minutes. The technical specifications and information on the products n the technical data sheets and approvals...

Fixing the insulating boards Preparation for reinforcement After installation of the insulation, the surface is to be checked carefully to ensure it can receive render. Cracks and marks on joints resulting from thermal bridges can be avoided in this way. 1 Checking the insulating boards Before applying the reinforcement, verify that the insulating boards have been jointed and rasped level over the entire surface. Do not apply the reinforcement until the PU bonding foam has hardened – and after 2 hours at the earliest. 2 Closing joints Close open joints with Sto PU filler foam or strips of insulation...
