Alpha Clad can supply an array of spacer systems, designed to offer optimum
performance for a multitude of cladding specifications.
From traditional bar and bracket spacer system for standard ‘U’ value built up roof and vertical wall cladding
applications to specialist deep roof construction and horizontal cladding systems, Alpha Clad can specify the product
most suitable for your application. A selection of options is listed below:
For further information beyond the scope of this web-site please contact us direct where we can discuss your
specific requirements and offer advice on the exact cavity depths necessary to meet your ‘U’ value requirements.
• Bar and Bracket Spacer System:
A spacer system developed to replace the ‘zed and ferrule’ systems used within early built up insulated roof and
vertical wall cladding constructions. As regulations called for more onerous ‘U’ value compliance, deeper
constructions became necessary and the zed & ferrule approach became structurally unstable. The bar and bracket
system was the industry’s solution. This grid-tite system comprises an ‘L’ shaped bracket of chosen depth, complete
with thermal break pad on the base, which twists into a profiled spacer bar. Typically the spacer brackets are set at
1m modular centres along the spacer bar suiting the cover width of the lining panel. However, bracket centres can
be reduced where extreme wind loadings dictate.
Scaling in 10mm increments this spacer system is generally used to create cavites between 60-220mm deep.
• Deep Bar and Bracket Spacer System:
We are seeing ever increasing demands for systems that exceed current thermal transmission requirements with
design ‘U’ values lower than 0.14W/m2K. To cater for these design stipulations, Alpha Clad can supply spacer
systems as deep as 400mm. These systems are installed in a similar way to the ‘L’ shape bracket and bar systems
but comprise a bracket that is structurally superior. Due to the amount of insulation necessary to comply with these
designs it is recommended that the internal lining is supplied in 0.70mm steel using a profile at least 32mm deep.
This allows roof constructions to be fully ‘lined out’ prior to placement of spacer system and insulation quilt, thus
creating a working platform.
• Horizontal Cladding Spacer Systems:
Bar and bracket systems are exceptionally strong when subjected to compression and tension forces. However,
whilst they can be installed in a vertical plane to accept horizontal wall cladding they are relatively weak in ‘shear’.
Alpha Clad can offer advice on how to overcome these issues when utilising the above system types or alternatively
design bespoke systems consisting of vertical zed spacers secured to strong in-plane shear brackets. These are
easy to install and as with all systems, calculations can be provided to confirm the load of the wall is adequately
distributed and withstood at all connections.
