Introduction
1.1 Chase EPS External Wall Cladding System
Chase EPS External Wall Cladding System, is a systematic, lightweight polystyrene cladding with a visually
appealing rendered finish that can be installed direct fix or via a cavity system (EPS, timber or steel battens).
This technical information & installation manual is designed for use by builders & installers to provide all the
relevant information about how to install the system to meet Building Code of Australia (BCA) requirements.
The National Construction Code 2019 (NCC) – Building Code of Australia, Volume 2 for Class 1 & 10 buildings is
a performance based code. Chase EPS has been extensively tested & is certified to meet the performance
requirements prescribed by the code:
• Structure: (P2.1 Structural stability and
resistance to actions)
Tested and appraised for serviceability and
strength under wind loads up to:
o AS 4055 Wind Class N4 for 75mm
minimum thickness panels, and N3
for 50mm thickness panels;
o AS/NZS 1170.2 serviceability wind
pressures Ws= +0.82kPa & -1.23kPa,
and ultimate limit state wind
pressures of 3.42kPa for minimum
75mm thickness panels and 2.03kPa
for 50mm thickness panels.
• Weatherproofing and Dampness: (P2.2.2
Weatherproofing, P2.2.3 Dampness) Tested
and appraised for resistance to moisture from
the ground and the penetration of water.
• Bushfire Prone Areas (P2.7.5)- Tested and appraised
in accordance with AS1530.8.1:2018, for Bushfire
Attack Level exposure up to 29 kW/m
2
(BAL 29) .
• Fire : (P2.3.1 Fire Separation)
Chase EPS External Wall Cladding System is
combustible as defined by the NCC 2019 BCA
Volume 2 and must not be located less than
900mm from boundaries or 1800mm from
another building, as defined in 3.7.1.3.
• Energy Efficiency: (P2.6.1 Building).

2System Summary
5
The Chase EPS panel, screwed through breathable
builders paper to the external wall framing, is
finished on-site with the Chase render system. This
incorporates Chase fibreglass mesh embedded into
an initial base coat of Chase EPS render, followed by
a second base coat layer and finished with Chase
tintable texture.
Optional :
• Chase primer (tintable) – The primer assists in
adhesion of the texture coat;
• Chase membrane (tintable) – The membrane
will assist in prolonging the life of the system
(particularly texture) as a whole.
Chase EPS panel is lightweight making for easy
handling and installation while also providing a
continuous thermal barrier to the heat and cold.
The Chase EPS External Wall Cladding System provides
the appearance of a rendered masonry wall without
the increased site preparation, cost and time of high-
mass construction. It is designed to be installed on
parapets and bulkheads which allows the designer
the freedom to achieve various finishes on the same
façade.
External wall cladding system selection and design
for any building, must be made by a person who
understands all the relevant local and national building
requirements, the technical aspects of the product and
its proper use.
Product installation must be carried out by a
tradesman under the direction of a Registered Builder
who both understand the technical information and
method of installation of the system.

System Summary
Chase EPS External Wall Cladding System consists of M Grade expanded polystyrene directly screwed or
installed via a cavity system, to either steel or timber wall framing through breathable wall wrap.
The system is very versatile due to the capability of both direct fix or a cavity system and is designed to be used
in residential construction. Examples of applications include external walls, parapets, bulkheads, fences and
columns.

2.1 Benefits
Chase EPS External Wall panels are
available as a standard size of 2400mm
x 1200mm with thicknesses of 50mm,
75mm and 100mm.
Chase EPS benefits include:
Energy efficient construction by
continuous insulation over the framing;
Versatility to satisfy different
architectural forms;
Lightweight for quick and
cost-effective installation;
Weatherproofing, durability,
impact & moisture resistance;
External Insulation & Finish System
(EIFS) is a well-known system for
builders and renderers.
Chase EPS External Wall Cladding System is designed
for Australian conditions. This method has been used
successfully for many years in Europe. EIFS is a
lightweight system that has design flexibility that
provides peace of mind.
Chase EPS External Wall Cladding System is versatile, light weight and
energy efficient and has been designed for Australian conditions.
