ACS 25/15 Framefix Channel & 4000 Range Ties

ACS Framefix™ is designed to allow an outer leaf of a cavity wall constructed from masonry to be tied to a light steel frame or another structural element through mineral wool using a suitable fixing. The system comprises of a number of elements that work together to create a high strength structural restraint assembly.

The channel itself is formed from Ultra Steel allowing higher capacities than plain steel channels. Along the channel are a number of pre-punched holes which are spaced at close centres to allow the fixing point to be selected depending on the application. For light gauge steel frames the smaller hole is designed to be used with ACS high thread self drilling fixings. All ACS fixings used with Framefix™ systems are supplied in stainless steel based upon independent reporting and testing by leading

industry consultants Sandberg LLP.

At each fixing point, a composite, high compressive strength sleeve is located to provide a high capacity fixing detail at even the largest of insulation thicknesses used on modern construction sites.

Once fixed, ACS 4000 range wall ties can be positioned at any point along the channel to suit the coursing of the masonry panel.

Features and benefits:

• Austenitic stainless steel, 1.4301 (304) grade.
• UKCA / CE+UKNI marked.
• Lucideon tested.
• Masonry - channel tie.
• 2700 mm standard length.
• Compression sleeves.
• Stainless steel fixings (extended lifespan when compared to zinc-coated alternatives).

Compression Sleeves:

The ACS Framefix™ system is supplied with compression sleeves which correspond to the thickness of the insulation specified. The tubes are designed to ensure that the compressive strength and stability of the channel tie system are both achieved and maintained by preventing the channel deflecting into and compressing the insulation during installation, and whilst under normal load. The tubes are manufactured from a fire-resistant composite material with thermal conductivity of 0.600 W/mK. Sleeve lengths should be selected to correspond with insulation thickness.
