EJOT UK has released the first range to what will be a complete family of high performance SIPs fasteners. The Yorkshire based manufacturer has an industrious R&D team at the hub of its operation and with a multitude of speciality fasteners already in place to fix rainscreen envelope components to structural panels – the natural progression was to create a range specifically to secure SIPs to substrate.

EJOT’s first release, ‘SIPstimber’, includes a fastener to secure SIPs to timber, plus a version designed for fixing panel to panel. Key to development was the team’s aim to arrive at a common diameter – in this instance 7mm. EJOT’s Technical Manager, Brian Mack explains; “we wanted a common diameter to work efficiently across a range of fastener lengths. A larger diameter is proven to yield high pull-out strength and shear values, creating a positive clamping effect”.

EJOT has determined fastener lengths to correspond to the depths of all main SIPs being currently installed. A positive recess affords installers to drive the fastener cleanly and securely via a torx T30 bit. Manufactured using case-hardened carbon steel to DIN EN ISO 10666, the SIPStimber JT2-SP2-7 range is organically coated for 1000 hour corrosion resistance.
