RocketClip Cladding

Number of RocketClips per m²

• A cross-joint is assumed to have a maximum centre-to-centre distance (up to max. 35 kg of cladding per m²) of 600 mm horizontally and 800 mm vertically, if using vertical battens in the RocketClips.


• For a single connection using horizontal battens in RocketClips, we recommend a centre-to-centre distance of 600 mm and spacing of 600 mm


• For cladding weights over 35 kg per m², please consult a Würth technical adviser

Mounting insulation panels and RocketClips

• Always position panels according to the manufacturer's specifications


• Position the insulation panel against the substructure (securing temporarily using adhesive foam is recommended)


• Drill a hole 10 mm in diameter at least 60 mm into the substructure. Choose the appropriate drilling method and type of core drill bit for the surface. A rotary hammer drill should always be used to drill into perforated bricks. Use a hammer or impact drill for solid bricks and concrete. Not applicable for CLT substructures.


• Clean the drill hole (blow out, brush, blow out)


• Push the RocketClip extension into the insulation panel until it cannot go in any further. Use a 20 mm flat drill bit to pre-drill a hole with a depth of 30 mm in the Multitherm wooden plate


• Push the specified SHARK UR® 10 plastic frame anchor into the RocketClip extension (not applicable for CLT)


• Secure the plastic frame anchor to the substructure with a bit extender


• The length of the anchor is the insulation thickness + 20 mm


• The anchor must be inserted at least 50 mm into the substructure


• Tighten the screw until the batten bracket visibly pulls into the insulation


• In accordance with the ETA approval for the SHARK UR® plastic frame anchor, the screw heads must be coated with corrosion protection spray after installation


• Push the plastic plug-in cap supplied into the extension to ensure a watertight and airtight seal


• Where necessary, install Belleville anchors as specified by the insulation panel manufacturer so that the insulation panel is always attached to the façade with a sufficient number of attachment points

Mounting wooden battens

• We recommend using treated wooden battens measuring 44x44 mm of at least quality class C18


• Mount the planed wooden battens in the RocketClips


• The slotted hole serves as a guide to help ensure level installation and is not suitable for mounting battens permanently


• Screw two of the specified stainless steel half round head screws (4x30 mm) into the small holes on each side
