The Aquadyne Living Wall by Cityroofs UK Ltd was tentatively launched in 2008 but completely re-designed with Halfen technology and experience for 2009. A living façade reducing the impact of solar gain upon a structure. The solution employs lightweight supporting structures designed by Halfen, a hydroponic irrigation system supplies sufficient nutrients and water through the Aquadyne system to support plant growth. The soilless solution is designed to incorporate rainwater harvesting, photovoltaic's and possible edible food sources.

The toothed lips of the HZA-PS channel match the teeth on the HZS T-bolt providing an adjustable connection with a secure mechanical interlock, which enables a reliable fixing for longitudinal loads as the connection is less reliant on torque and friction to resist slip.

Key features include:
Higher and more reliable longitudinal capacity Hot rolled channel ensures better dynamic performance Welded "I"-anchors provide stronger connection, deeper embedment and improved dynamic performance

The HZA-PS anchors are designed for improved performance in cracked concrete and are suitable for crack widths of up to 1.5mm.

Available in both carbon steel and hot dipped galvanized or in A4 stainless steel - the channel is designed to meet most requirements.

To meet increasing demand Halfen - the name for cast-in channels, have launched their FRS Frame Restraint System for economical restraint of external masonry back to steel studwork.

The FRS system comprises of standard 2.7m lengths of 25/14 channel with pre-drilled holes to allow simple fixing back to the studwork, self drill fasteners and special ties designed to provide a secure fit within the lips of the channel.

In order to maximise effective and economical use of the channel, fixing centres are at 110mm - which allows the channel to be cut onsite without excessive channel overhang past the last fixing, avoiding unnecessary wastage.

Ease of installation and flexibility are further increased by the FRS self-drill fasteners which can accommodate 30-100mm of rigid insulation board and can be fixed into steel studwork up to 6mm thick without the need for pre-drilling.

The special Halfen FRS ties are available in various lengths ranging from 100-200mm with a choice of bonded safety end or plain end with a plastic sleeve for debonding.

The full range, including all technical data is available on a new datasheet available from the Halfen website: www.halfen.co.uk/FRS

Halfen's SBC steel balcony connection system provides an economic and practical method for connecting steel balconies to concrete frames. The system comprises two main components.

The SBC anchor assembly which is cast into the reinforced concrete slab.
The SBC bracket which is bolted on to the assembly and unlike some other systems, enables the masonry or cladding to be completed before installation of the balconies.

Key features

• Easy to install
• Convenient slab edge connection
• An efficient method of connection. Steel balconies can be bolted on to the front plate after the brickwork or cladding has been completed.
• Thermal separation of the bracket.
• Easy to finish and seal around the bracket body
• Horizontal and vertical adjustment.
