Description

Reflecta™ Guard Plus
High-Performance Reflective Insulation for Roofs & Walls

 

Reflecta™ Guard Plus is a premium, Australian-made reflective insulation designed for diverse applications including roofing and wall systems. Featuring advanced dual-layer reflective aluminium technology, Reflecta™ Guard Plus offers superior thermal insulation, effective condensation control, acoustic insulation, and unmatched durability suited for commercial, residential, and industrial projects.

Why Choose Reflecta™ Guard Plus?

Exceptional Thermal Performance

Reflecta™ Guard Plus achieves outstanding thermal insulation performance, delivering Total R-Values of:

 

  • Roof: 3.1 (heatflow inward), 1.2 (heatflow outward)

 

  • Wall: 1.9 (both inward and outward)

 

  • Floor: 2.1 (heatflow inward), 2.7 (heatflow outward)

 

These high-performance ratings significantly improve comfort, enhance energy efficiency, and reduce energy costs.

Advanced Moisture and Condensation Management

With low vapour permeability (0.0090 µg/N.s), Reflecta™ Guard Plus is classified as a Class 2 Vapour Barrier, effectively preventing condensation-related problems such as mould, structural deterioration, and costly repairs.

Robust Weather Protection
Reflecta™ Guard Plus acts as a reliable water barrier, safeguarding building structures against moisture penetration, ensuring long-lasting durability and structural integrity.
High Strength & Extra Heavy-Duty Performance
With Extra Heavy-Duty ratings in edge tear resistance (TAPPI T470) and tensile strength (AS 1301.448s), Reflecta™ Guard Plus is built for maximum durability, reliability, and strength in demanding installation conditions.
Effective Acoustic Insulation
Reflecta™ Guard Plus delivers additional acoustic insulation, reducing noise by up to 10 dB in a 1/3 octave band, enhancing indoor comfort.
Easy Installation and Handling
Supplied in convenient rolls measuring 1.5m wide by 20m in length (30m² total coverage), Reflecta™ Guard Plus ensures easy handling, precise installation, reduced waste, and labour savings.
Safety and Durability
Reflecta™ Guard Plus features a low flammability index (≤5) and conductive surfaces (caution required near electrical installations). Additionally, it is fibre-free and fully recyclable, ensuring safer and environmentally-friendly installation practices.
Compliance and Safety

Reflecta™ Guard Plus meets Australian Standards AS/NZS 4859.1 and AS/NZS 4200.1, recognised by National Building Codes (NCC 2019 & 2022).

 

  • Electrical Conductivity: Conductive (exercise caution around electrical fittings).

 

  • Flammability Index: Low (≤5).

 

  • Emittance Values: Reflective Silver Side 0.03, Antiglare Side 0.05.

Warranty

Warranty Cover

GIBS warrants the products listed below against manufacturing defects for 15 years from the date of installation. The products are also warranted on delivery to meet the applicable GIBS product specifications and the standards stated in the relevant GIBS technical literature.

Conditions

This warranty applies only where the product remains unaltered, has been correctly stored and handled, and has been installed by a suitably qualified tradesperson in accordance with GIBS installation instructions and technical information current at the date of installation.

Claims

A warranty claim must be submitted to the supplier from whom the product was purchased, together with proof of purchase and sufficient details and evidence of the fault and its extent. The supplier must forward the claim to GIBS. All expenses incurred in making a claim under this warranty are borne by the claimant.

Remedy and Liability

Where GIBS accepts a valid warranty claim, GIBS may, at its option, repair, rectify or replace the affected product. GIBS’ liability is limited to the replacement cost of the defective material, reduced proportionately according to the part of the 15-year warranty period that has expired.

The warranty applies only to the original building project and is limited to the GIBS product found to be defective.

To the extent permitted by law, GIBS gives no other express or implied warranty in relation to the product, including its fitness for a particular residential or commercial application other than its published recommended use. Subject to rights that cannot lawfully be excluded, GIBS will not be liable in contract, tort, negligence, strict liability, breach of statutory duty or otherwise beyond the obligations stated in this warranty.

Exclusions

  • damage to other products used with a GIBS product, or damage resulting from the installation of those products;
  • claims relating to another manufacturer’s product;
  • damage arising from recommendations made by a GIBS representative concerning other products, materials or combinations of products;
  • damage caused by the installation or assembly of the GIBS product;
  • incorrect installation or incompatibility with other materials or products;
  • use of the product for applications or purposes outside its intended or published recommended use, including uses outside the building and construction industry;
  • damage caused by aggressive chemicals, incompatible metals, immersion in water, chemically treated or green timber, storm, tempest or other events beyond GIBS’ control; or
  • normal fair wear and tear.

 

The buyer is responsible for determining the suitability and compatibility of other products, materials, or the environment of the installation site used with GIBS products and should obtain independent advice where appropriate.

Transfer and Change of Use

This warranty applies only to the original project and application and is not transferable. A change in building ownership or in the purpose or use of the building will cancel this warranty unless GIBS is notified beforehand and confirms that the warranty remains valid for the proposed use.

Australian Consumer Law

This warranty is provided in addition to other rights and remedies available under law.

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
