Product Conditions

  1. Visual Quality
    Warranty applies to IGUs free from visual defects beyond acceptable limits defined in AS 4666 and AS 4667 at the time of manufacture.
  2. Laminated Glass
    Delamination or edge separation within laminated components is covered, except within 20mm of the glass edge.
  3. Post-Processing Exclusion
    Any IGU that undergoes further cutting, edge-working, film application, or modification after delivery is excluded from warranty coverage.
  4. Customer-Supplied Glass
    If glass is supplied by the customer, it must meet Novatec’s specifications and relevant Australian Standards. Written confirmation may be required.
  5. Delivery Acceptance
    By accepting delivery, the customer confirms the IGUs were received in good condition and free from visible defects.
  6. Handling & Environment
    The customer must ensure IGUs are protected from:
    • Contact with corrosive materials or chemicals
    • Prolonged exposure to moisture
    • Extreme temperatures exceeding 70°C
    • Radiation beyond normal sunlight
  1. Installation Requirements
    IGUs must be installed in accordance with AS 4666, ensuring no prolonged moisture contact at the glass edge.
  2. Sealant Compatibility
    Glazing sealants must be compatible with the IGU’s edge seal system and any laminated components.
  3. Exclusions
    Warranty is void if:
    • IGUs are improperly glazed
    • Damage results from external events (e.g., impact, natural disasters)
    • The product is used outside its intended scope or specification

Thermal Breakage & Heat Soak

  1. Thermal Risk Management
    For coated or tinted solar-absorbing glass, a thermal assessment is recommended. The customer is responsible for:
    • Requesting assessments and heat soak treatments in writing
    • Accepting recommendations to mitigate thermal breakage risks
    • Ensuring damaged or shelled glass is not installed

Note: Spontaneous breakage due to inclusions (e.g., Nickel Sulfide) is not covered. Heat soaking reduces but does not eliminate this risk.

Colour Variation

  1. Glass Colour Tolerance
    Minor colour variations may occur due to differences in raw materials or manufacturing conditions. Customers should consider this when ordering glass for visually sensitive applications.

Inspection Rights

  1. Field Inspection
    Novatec reserves the right to inspect any IGU subject to a warranty claim, in accordance with relevant Australian Standards and consumer law.

Defect Tolerances for Glass (Australia)

Glass quality in Australia is assessed according to standards such as AS 4667, which outline acceptable visual defects and inspection guidelines. These standards ensure safety and clarity for architectural and decorative glass applications.

Visual Defects and Tolerances

  • Scratches and Marks
    Must not be visible from 3 meters away when viewed through the glass under normal daylight conditions.
  • Bubbles / Seeds
    • Bubbles less than 1mm are not considered defects.
    • A single bubble between 1mm and 5mm is acceptable if there is no more than one per 1.6m².
    • Bubbles larger than 5mm are not permitted.
  • Chips
    On framed edges, chips up to 5mm deep are acceptable if the panel will be framed.
  • Defect Accumulation
    Four or more defects within 200mm of each other are considered a defect.

Inspection Guidelines

  • Viewing Distance: Inspect glass from 3 meters away.
  • Lighting: Use natural daylight, avoiding direct sunlight.
  • Position: Glass should be vertical, viewed perpendicular to the surface.
  • Viewing Area: Exclude a 50mm wide band around the edge for certain defects.
  • Panel Characteristics: Tolerances depend on size and type of glass, as per AS 4667.

Examples:

novatec glass 41
  • Scratches – Lines visible on the surface. 
  • Bubble / Seeds – Small round imperfections inside the glass. 
  • Chips – Missing fragments on the edge. 
  • Defect Accumulation – Multiple small defects clustered together.

DGU Defects: 

Acceptable Defects in IGUs (AS 4666 Guidelines)

Inspection is done from 3 meters away, under natural daylight, with glass viewed perpendicular to the surface. The outer 10–15% of the glass (secondary vision area) is more lenient than the central primary vision area.

  1. Scratches & Marks
    • Must not be visible from 3 meters in normal daylight.
    • Fine hairline scratches that disappear at this distance are acceptable.
  1. Bubbles / Seeds
    • < 1mm: Not considered a defect.
    • 1–5mm: One bubble per 1.6 m² is acceptable.
    • > 5mm: Not permitted in the primary vision area.
  1. Dust / Debris inside cavity
    • Small particles that are not visible from 3 meters are acceptable.
    • Large or clustered debris is considered a defect.
  1. Condensation
    • Temporary condensation during extreme weather is acceptable.
    • Persistent condensation inside the cavity indicates seal failure and is not acceptable.
  1. Chips on Edges
    • Up to 5mm deep on framed edges is acceptable if hidden by the frame.
  1. Defect Accumulation
    • Four or more defects within 200mm of each other is considered a defect.

Not Acceptable

  • Cracked panes.
  • Seal failure causing fogging or moisture ingress.
  • Bubbles larger than 5mm or multiple bubbles in the primary vision area.
  • Scratches visible from 3 meters.

Laminate Defects:

Accepted Defects (AS 4667 & Laminated Standards)

  • Bubbles <1mm in diameter.
  • One bubble between 1–5mm per 1.6m².
  • Slight haze or roller wave distortion not visible from 3m.
  • Edge slip up to 3mm between layers.

Not Accepted

  • Bubbles >5mm or multiple bubbles in primary vision area.
  • Delamination or edge separation beyond 6mm.
  • Foreign inclusions or contamination.
  • Persistent optical distortion visible from 3m.

  • Visual Defects – Minor haze or slight roller marks (often acceptable if not visible from 3m). 
  • Air Pockets – Irregular trapped air between layers (usually acceptable if very small and not clustered). 
  • Accepted Haze – Light haze within interlayer that does not impair vision from 3m. 
  • Not Accepted Inclusion – Foreign particles or large bubbles inside the laminate (always considered a defect).
