The complete choice of Vista movement ties wall ties and exactly where They can be suitable for use is outlined inside our web site publish ‘Movement Ties’
The ties work by corkscrewing into brick, block and concrete, providing a mechanical deal with that grips Every wall layer. A small pilot gap is necessary for installation into all masonry substrates other than aerated concrete.
These variety of programs secure cavity walls to overhead buildings, whilst accommodating vertical motion and therefore are made use of along side one way sliding ties or two way sliding ties.
Thor Helical cavity ties are manufactured in a variety of lengths and diameters. These exceptional cavity wall ties Possess a patented precision engineered helix that interlocks flawlessly To maximise general performance.
NCMA and the companies disseminating this specialized facts disclaim any and all responsibility and liability for that precision and the application of the data contained With this publication.

As the first North American — primarily based corporation to embrace the obstacle, we’re leveraging our dual passions of support and innovation to satisfy this field’s unique needs.
Normal anchors are shown in Determine 3. The shapes and sizes of those common anchors have progressed in excess of many years and fulfill the “constructability” criterion. All the anchors check here revealed are already tested Along with the resulting capacities demonstrated in Table one.
Even though They're hidden here from sight following construction, wall ties play a pivotal job during the properties stability.
The above tie-duration direction is for cavity walls with 110mm bricks. Make adjustments for walls with a hundred mm metric bricks.
When usual ties and anchors are thoroughly embedded in mortar or grout, mortar pullout or pushout will not likely normally be the controlling manner of failure. Specification for Masonry Buildings calls for that connectors be embedded a minimum of one½ in. (38 mm) right into a mortar bed of sound models. The expected embedment of unit ties in hollow masonry is this kind of which the tie have to lengthen completely over the hollow units.
Larger core diameter presents larger torsional potential, resulting in a lot less deflection because of “uncoiling” underneath load.
The VE4 light-weight duty housing tie is our normal Variety four tie as well as Neutras variety are minimal thermal conductivity wall ties.
Added assessments are essential for adjustable anchors of various configurations and for just one piece anchors. Proprietary anchors also are out there. Brands of proprietary anchors should furnish test data to doc comparability with industry-analyzed anchors.
