Iso-Brick Method of Installation
| |
|
|
| 01. Aluminium base profile is lined and leveled and mechanically fixed
around perimeter of building (to provide horizontal alignment, to close
off void and to provide bottom drip detail). |
|
 |
| |
|
|
| 02. Preformed corner units and window jamb/head/cill units are fixed to
the substructure, followed by the main standard panels (these being
cut to suit infill dimensions on site using a diamond bladed portable
cutter). |
|
 |
| |
|
|
| 03. Fixing of each panel is by both adhesive gunned onto rear surface of
the panel where required and by mechanical anchors (minimum 9No. fixings
per standard wall panel, using factory determined pre-made fixing points
- although this may be increased for multi storey buildings and to suit
wind loadings). Panels are also packed and shimmed off substrate as
necessary to provide line and level where required. |
|
 |
| |
|
|
| 04. Foam injection is then used to seal the adjacent panels using pressurised
polyurethane foam, which fills the moulded recess incorporated around
the edges of each panel. Any site cut panels are routered on their cut
edges to form a new recess edge condition. |
|
 |
| |
|
|
| 05. To achieve the full bond for stretcher coursing at junctions between
the vertical panels, alternate course brick tiles are supplied loose
and are adhered to bridge between the adjacent panels using ISO-BRICK
2 part polyurethane adhesive. Any necessary pre-bonded tiles requiring
removal from cut edges of infill panels are removed on site using a
portable cutter and/or boulster with the tiles being prised off. |
|
 |
| |
|
|
| 06. Finally, the panels are mortared using special pointing mortar
which would be supplied with the system, applied via a pointing gun
or hand pointed application and tooled to form the desired joint profile. |
|
 |
Note: The incorporation of thermal movement joints for overcladding
projects will be required to coordinate with any existing movement joint
positions to brick/blockwork behind, this is achieved by forming a back
to back aluminium profile detail. For new build projects please consult
NBS for specific details relating to the various forms of substructure.
