Thermal Performance & Warranty

R-values, U-values and comprehensive product warranties for long-term performance.

Thermal Ratings Explained

R-Value – Thermal resistance. Higher = better insulation.

U-Value – Heat transfer rate. Lower = better performance.

System	R-Value	U-Value
Standard Metal Roof	R-0.5	1.80
Insulated Panel 50 mm	R-2.3	0.43
Insulated Panel 80 mm	R-3.7	0.27
Insulated Panel 100 mm	R-4.6	0.22
Standing Seam + Blanket	R-3.0+	0.33

Product Warranties

Product	Warranty Period
Colorbond / Metal Roofing	20–30 years (perforation)
Insulated Roof Panels	15–25 years (core & finish)
Composite Cladding	15 years
Composite Decking	25 years
Standing Seam Systems	20–30 years
Accessories & Flashings	10–15 years

Warranties are subject to correct installation and maintenance. Full warranty certificates are issued with every order confirmation email.

What Is Covered

• Material defects and premature degradation
• Perforation due to corrosion (metal products)
• Delamination or core failure (insulated panels)
• Colour fade beyond published limits
• Structural performance under normal conditions

Extended warranty options available for commercial projects on request.

Acoustic Insulation Ratings

Sound reduction performance for commercial and residential applications where noise control is critical.

Key Acoustic Metrics

Rw (Weighted Sound Reduction Index) – Measures airborne sound insulation. Higher Rw = better sound reduction.

NRC (Noise Reduction Coefficient) – Measures sound absorption. Higher NRC = more absorption.

Our insulated panel systems can significantly reduce rain noise and external airborne sound.

Typical Acoustic Performance

System	Rw (approx)	Notes
Single skin metal roof	18–22 dB	Basic reduction
Metal + acoustic blanket	28–32 dB	Improved rain noise
50 mm insulated panel	30–34 dB	Good all-round
80–100 mm insulated panel	34–38 dB	High performance
Panel + acoustic liner	40+ dB	Specialist applications

Applications

• Schools and educational buildings
• Healthcare facilities
• Offices and commercial interiors
• Residential near transport corridors
• Industrial buildings requiring noise control

Detailed acoustic test reports available with commercial quotations.

Sustainable Roofing Materials

Environmentally responsible options that support green building certifications and long-term sustainability goals.

Sustainable Material Options

Recycled Content Metal
Many of our steel and aluminium products contain high percentages of recycled content and are 100% recyclable at end of life.

Cool Roof Coatings
High-reflectance finishes reduce urban heat island effect and lower cooling loads.

Long-Life Materials
Extended service life (20–40+ years) reduces replacement frequency and embodied carbon over the building lifecycle.

Environmental Benefits

Feature	Benefit
High recycled content	Lower embodied carbon
Fully recyclable	Circular economy support
Cool roof finishes	Reduced cooling energy
Durable coatings	Fewer replacements
Lightweight systems	Lower structural demand

Certification Support

Our products can contribute to:

• LEED credits (Materials & Resources, Energy)
• BREEAM assessments
• Green Star ratings
• Local green building schemes

Environmental Product Declarations (EPDs) and recycled content statements are available on request and are included with commercial order documentation.

Commercial Roofing Guide

Practical steps for selecting and specifying the right commercial roofing system.

1

Define Project Requirements

Building use, location, wind/snow loads, thermal targets, acoustic needs, fire rating and sustainability goals.

2

Select Roof Type

Standing seam, insulated panels or industrial trapezoidal profiles according to performance and budget priorities.

3

Check Thermal, Acoustic & Fire Data

Match R-value, Rw and fire classification to code and project requirements.

4

Review Sustainability Credentials

Request EPDs, recycled content data and cool-roof options where green certification is required.

5
