Exsulite® Frequently Asked Questions

Please read our frequently asked questions (FAQs). If your question is not answered here please let us know through our contact page.

What is Exsulite?

Exsulite is a cavity wall cladding system suitable for residential and multi-residential construction projects. It can also be used as a remedial facade system for renovation projects when used as a direct fix system.

What experience does Exsulite have in Australia?

At Dulux® AcraTex® we’ve been designing specialist finishing systems for new construction for over 3 decades protecting some of Australia‘s landmark architecture and infrastructure projects and working with Substrate Supply Partners to deliver total piece of mind with appropriate coatings specifications. EIFS is not new to AcraTex – in fact as a founder in the Acrylic Texture market over 30 years ago, AcraTex was a pioneer in the use of EIFS systems designing and installing systems specifically for Insulation benefits as originally used in Europe. AcraTex Exsulite has been a brand of Dulux for over 25 years.

How is it different from other walling systems?

EIFS (External Insulation & Finishing Systems) offer efficient installation and high thermal efficiency with strength and durability delivered by a fibreglass reinforced high impact strength multi-layered coating system.
The Exsulite (EIFS) System is a fully integrated (single supply source from cladding right through to external coating) giving you total peace of mind when installed by an Exsulite Trained & Registered Installer.

Why is Exsulite superior?

Exsulite is backed by Dulux and is installed by Exsulite Trained & Registered Installers for total peace of mind.

How is it installed?

The Exsulite Trained & Registered Installer installs the system once the building framework, whether timber or steel is in place. Installation detail is defined in the Exsulite Specification & Installation Manual in conjunction with the relevant Exsulite Construction drawings. A Certificate of Installation issued by an Exsulite Registered Installer provides peace of mind that the system as built meets design specification. Exsulite Registered Installers can be verified by their Exsulite Registration Card and Registration Number.

What QA systems are in place?

A Certificate of Installation is offered following project completion ensuring all proper installation processes have been followed. A Certificate of Installation issued by an Exsulite Registered Installer provides peace of mind that the system as built meets design specification. Exsulite Registered installers can be verified by their Exsulite Registration Card and Registration Number.

Is it fire resistant?

Exsulite-EPS is rated to BAL29 (Bushfire Attack Level 29), suitable for use in High Risk areas as defined in Australian Standard “AS 3959 : Construction of Buildings in Bushfire Prone areas”. AS 3959 divides bushfire prone areas into six bushfire attack levels (BAL), based on the severity of the building’s potential exposure to ember attack, radiant heat and direct flame contact as follows:

BAL-LOW – very low risk
BAL-12.5 – low risk
BAL-19 – moderate risk
BAL-29 – high risk
BAL-40 – very high risk
BAL-FZ – extreme risk (Flame Zone)

Exsulite-Kooltherm® is rated to FRL (Fire Resistance Level) of 60/60/60 to Australian Standard “AS 1530.4  : Fire Resistance Tests of Elements of Building Construction”. FRL is reported by 3 numbers eg 60/60/60 representing a pass at 60 minutes in all three FRL test indices of  structural adequacy/integrity/insulation and FRL60/60/60 rating meets the requirement for Fire Separating Walls (or party walls) as defined under Part 3.7.1 of the BCA.

Compliance to standard is relative to the Specification & Installation of the Full System as detailed in the relevant System Certification.

Is it certified?

Exsulite and Exsulite-Kooltherm are CodeMarkTM certified as fully integrated Building Systems in compliance with the Building Code of Australia (Volume Two, Class 1 and 10 Residential Buildings). Exsulite-Kooltherm is also certified for Multi-Residential External Walls to NCC (Volume One, Class 2 to 9 buildings). An Exsulite Certificate of Installation from a registered Exsulite Installer provides peace of mind that the system “as built” meets Design Specification.

Compliance to standard is relative to the Specification & Installation of the Full System as detailed in the relevant System Certification.

How water resistant is it?

Exsulite Systems are CodeMark certified for compliance with the BCA including Weatherproofing Performance. Integration of design, components and installation is critical in ensuring long term performance which is why Exsulite is designed as a total system from Exsulite Vapour Permeable Building Wrap right through to Exsulite Weatherproofing Finishing Systems.

Compliance to standard is relative to the Specification & Installation of the Full System as detailed in the relevant System Certification.

How does it perform for thermal efficiency?

The Exsulite-EPS Thermal Facade System offers a high insulation performance up to R4.9. Subject to system specifications.
The Exsulite-Kooltherm Thermal Facade System offers a high insulation performance up to R7. Subject to system specifications.

How do I order it?

Your architect or builder will order the total Exsulite system including all panels and fixings from Dulux AcraTex or an approved distributor.
