Ties for Thin-Joint Blockwork
Staifix-Thor Helical TJ2 Wall Tie
Thin-joint construction prevents the use of traditional cavity wall ties requiring embedment in 10mm joints and coursing between the inner and outer leaves. The joints in the inner leaf of blockwork are reduced to 3mm or less by the use of special thin-joint mortar.
The TJ2 wall tie is ideal for thin-joint blockwork and other applications where the joints in the inner and outer leaves are not aligned. It is hammered directly into aerated concrete blocks, through insulation material, and is built into the bed joints of the outer leaf of brickwork.
This tie meets the requirements of PD 6697 as a type 2 or 3 tie depending on the block used and the cavity width:
|Block Strength N/mm2||50 / 75 / 100mm Cavity||125 / 150mm Cavity|
|2.8 - 4.0||Type 3||Type 3|
|7.0 - 10.5||Type 2||Type 3|
The black Staifix TJ Clip is designed for use with TJ2 wall ties.
For thin-joint to thin-joint separating walls use the Staifix HRT4.
|205mm for 50mm cavities|
|230mm for 75mm cavities|
|255mm for 100mm cavities|
|280mm for 125mm cavities|
|305mm for 150mm cavities|
Following recent fire tests at BRE Global, Ancon is pleased to confirm that its innovative basalt-fibre, low thermal conductivity wall ties, Teplo-BF and Teplo-L, offer 120 minute fire resistance, making them suitable for buildings of any height.
After a string of Awards successes for the Teplo range, the new Teplo-BF low thermal conductivity wall tie has been shortlisted in the ‘Best Innovation in Insulation” category of the 2016 Build It Awards.
