What types of wall ties are there?
Type 1 Wall Ties
Type 1 wall ties are a heavy Duty wall tie, designed to be used in high rise, public and commercial buildings. Its innovative shape and design gives it superior strength and must meet requirements stated in DD140: Part 2. The ACS 2000 range wall tie is designed to exceed these requirements and can be used within buildings of any height throughout the UK. Its innovative, unique design gives it superior strength and its shape and fine micro coating ensure moisture is not transmitted across the body of the tie.
Type 2 Wall Ties
Type 2 wall ties or general purpose wall ties, join together two masonry/blockwork leaves. Designed for use on domestic or small commercial buildings up to 3 storeys or 15 meters in height. Type 2 wall ties can be used in cavities up to 100mm.
Type 3 wall ties
Type 3 wall ties are a basic duty wire design which are ties to tie two masonry leaves together. These wall ties can be used in commercial or domestic buildings up to 15m in height providing the wind speed is limited to 25m/sec. As a general rule, ACS recommend opting for either a type 2 or type 4 wall tie due to their increased compatibility and availability.
Type 4 wall ties
Type 4 wall ties are a light duty wall tie which is used to join together two masonry leaves. Designed for use on domestic homes up to 10 meters in height. Type 4 wall ties are suitable for cavities up to 100mm and must meet standards outlined in BSEN 845-1.
Channel ties work in conjunction with ACS Axis channel, cast in channel and frame fix channel. Channel ties have a dovetail design which matches our channel perfectly whilst being compatible with other brands. A channel tie is designed to restrain masonry brickwork to either the concrete slab, timber or steel frame
Movement Wall Tie
A movement wall tie is used in conjunction with a debonding sleeve, these can either be a frame cramp or a flat bar wall tie. Used over movement joints the specifically designed sleeve has a viewing window ensuring a 10mm gap is achieved. One side of the tie is fixed, the other side sits within the debonding sleeve, the shape of the sleeve and the tie allows for free lateral movement as required. The debonding sleeve is embedded into the mortar restricting movement to the 10mm requirement
Frame cramps are a type of wall tie used with an in-situ structure of either concrete, steel or wood. The frame cramp is usually fixed at 225mm intervals ensuring the new masonry structure is correctly supported and fixed to the structure. Transfix tape is commonly used as this ensures the correct spacing of frame cramp wall ties.
Column Wall Ties
Column wall ties are used to fix masonry to steelwork. The intuitive design eliminates time-consuming drilling and bolting of frame cramps. The design allows for variations in coursing and can be used on various profile types of steel column.
Timber Wall Tie
Timber wall ties are used to fix masonry to timber frame structures. Suitable for use on buildings up to 5 storeys or 15 meters in height and designed for use on cavities up to 100mm. Timber wall ties must meet type 5 requirements and BS5268-6.1 standards.
Two part ties (TPT) are a heavy duty wall tie which exceeds type 2 wall tie requirements BE EN 845-1 up to a 250mm cavity. Thereafter, meeting the requirements of a type 3 tie BSEN 845-1 up to 350mm cavity. Designed for use in longer cavities that range from 150mm and above. The TPT is easier to install than a one-piece product as the inner section is installed to the inner leaf and then the outer section is installed during the construction of the outer leaf. Longer wall ties have a tendency to drop due to the weight of the product, once the mortar has set the tie should not be bent to accommodate the outer leaf coursing.
Clasp ties are designed to fix masonry to steel. A tech screw is fixed directly to the steelwork with a neoprene isolation sleeve to prevent any bi-metallic corrosion or reaction
Acoustic wall ties
Acoustic wall ties are designed to reduce the noise transfer by minimising the vibrations between external and internal brickwork partitions. A high-quality rubber shim isolator absorbs vibrations which cause noise to travel. Acoustic wall ties are available in postfix and cavity wall tie variations
Remedial Wall Ties
A remedial wall tie is used to replace old failing wall ties or when the installation of wall ties have been omitted or incorrectly installed. There are various types of remedial wall tie due to different types of construction.
Resin fix anchors are used where the inner leaf of blockwork is likely to crumble during the fixing process, instead of compressing the block, the resin allows the anchor to be fixed without pressure.
Mechanical fix anchors are used when the inner leaf of blockwork is suitable and strong enough to be compressed without compromising the structure of the block.
