Specifications

Before the Chase EPS External Wall Cladding System
can be installed, all wall framing must be constructed
and detailed to comply with the relevant regulations.

The placement & detail of correct installation of con-
trol joints is the responsibility of the Designer, Archi-
tect & Builder.

Good cladding system building practice typically
requires expansion joints every 6-8m and at each
floor level (eg, 3m high).

Control joints should correspond with control joints
of the building structure. This is typically at all weak
or stress points and at all joints between different
building substrates.

‘Articulation Relief Joints’ of the render coating are
also recommended for the control of cracking/hair-
line fractures. Articulation Joints should be installed
vertically in line with the sides of doors, windows &
openings, as well as in areas where the EPS section is
less than 300mm in height (eg, above/below window
& door heads).

These should be installed by forming or cutting a ‘V’
groove to a depth of at least 50% into the render base
coats without penetrating the mesh layer. This groove
is to be reproduced as a visible line in the texture coat.

Again, it is the responsibility of the Designer, Architect
& Builder to ultimately determine the most appropri-
ate approach for the specific project.

All facets of the design, supply and correct installation
of penetrations in the cladding system, e.g. windows,
doors etc., are outside the scope of the Chase EPS
External Wall Cladding System. The Designer and
Builder must ensure that the building, including all
drainage holes and integral flashings in all
penetrations will prevent the ingress of rain water
behind the EPS panel and will drain to the outside of
the building.

Variations in the strength, stiffness, straightness
and squareness of the wall framing will affect the
cladding system and must be checked, and rectified
as necessary, before any cladding installation can
begin.

In all cases the Chase EPS External Wall Cladding
System may only be installed in accordance with
this manual on steel or timber wall framing with a
maximum stud spacing of 600mm.

5.1 Installation to Achieve Bushfire Attack Level (BAL 29)

In order to achieve BAL 29, The complete Chase EPS External Wall Cladding System must be used.

The System must be installed in accordance with this manual and be comprised of a precise group of specified
materials to meet the Bushfire Attack Level standard as tested (AS1530.8.1-2018). This includes 50mm, 75mm
or 100mm Chase panel; Chase aluminium U-shape (boot) or L-shape, aluminium starter channels (required
where the bottom edge of panel is unprotected); Chase fixings and washers, Chase 160 g/m

fiberglass mesh,

Foam Sealant, window flashing tape, Chase Render (2 coats @ 3mm each), Chase Texture, Sealant- Bostik
Fireban One (by Builder).

Prior to Installation

1. Ensure the wall frame is square, level and
plumb;

2. Check that the stud spacing does not

exceed 600 mm;

3. Ensure panel edges that are parallel to the

studs are supported so that fixings can be

applied between 50mm to 150mm from the

panel edge as required;

To achieve this requirement, additional

framing and/or back blocking may be required
