Anticon™ Defined — Foil-Faced Glasswool Roofing Blanket
CSR Bradford Anticon™ is a continuous
glasswool blanket bonded to a polyweave-reinforced reflective foil on the underside. The product is rolled
out across roof purlins before the metal roof sheet (Colorbond, Trimdek, Kliplok) is fixed down — the foil
faces into the building, the glasswool body sits between purlin and sheet. Bradford’s product page describes the
application range as
“residential and commercial metal roof applications”.
Anticon is one of the few warehouse roofing materials that delivers four functions in a single product layer:
- Radiant-heat reduction — the foil face reflects radiant heat away from the building interior, the dominant heat-gain pathway through a metal roof in Brisbane summer.
- Conductive insulation — the glasswool body provides a measured R-value (R1.3 to R4.2 across the standard range) certified to AS/NZS 4859.1.
- Acoustic absorption — the glasswool absorbs the impact noise of rain on metal sheets, a meaningful benefit in Brisbane’s storm season for occupied warehouse spaces.
- Condensation control — the foil acts as a vapour barrier under the metal sheet, reducing the dew-point condensation that drips into bulk insulation and corrodes purlins over time.
Bradford rates Anticon for BAL 12.5-FZ bushfire performance when installed to specification —
relevant for warehouses in semi-rural fringes of South East Queensland. The product is manufactured in
Australia and carries current AS/NZS 4859.1 certification across the full variant range.
installs the standard Anticon range and Anticon High Performance variants across Class 5–9 commercial buildings
from Eagle Farm to
Yatala.
Anticon™ Variants by Thickness and R-Value
Anticon is sold by thickness — the R-value is a function of the glasswool depth. Variant selection is driven by
the Section J Total R-value target for your project,
the available purlin-to-sheet gap, and whether the project is a single-layer or combined-system specification.
Standard Anticon Range
| Thickness | Material R-value | Typical application | Indicative installed cost / m² |
|---|---|---|---|
| Anticon 60 | R1.3 | Light-duty sheds, carports, minimal-spec workshops | $13–$20 |
| Anticon 80 | R1.8 | Class 7b storage warehouses (with sarking), retail roofs, light commercial | $15–$25 |
| Anticon 90 | R2.0 | Mid-range warehouse roofs (combined-system) | $16–$26 |
| Anticon 100 | R2.3 | Commercial roofs targeting R3.0+ system with sarking | $17–$27 |
| Anticon 110 | R2.5 | Mid-spec Class 5/6/7b roofs | $18–$28 |
| Anticon 130 | R3.0 | NCC Section J Climate Zone 2 — primary spec (R3.0 + sarking R0.7–1.0 = R3.7+ system) | $20–$30 |
| Anticon 140 | R3.3 | Higher-target Section J / cold-climate adjacent | $21–$31 |
| Anticon 145 | R3.6 | Section J single-layer pathway (without sarking dependency) | $22–$32 |
| Anticon 175 | R4.2 | Maximum standard R-value — Climate Zone 7 applications, conditioned spaces | $25–$36 |
Anticon High Performance Range
Anticon HP uses a denser glasswool formulation to deliver higher R-values at lower thicknesses — useful when
purlin-to-sheet clearance is tight or single-layer Section J compliance is the design intent.
| Thickness | Material R-value | Why specify HP over standard | Indicative installed cost / m² |
|---|---|---|---|
| Anticon HP 100 | R2.5 | Same R-value as standard 110mm at lower thickness — useful for tight purlin clearance | $19–$29 |
| Anticon HP 130 | R3.6 | Hits Section J Total R3.7 as a single-layer system without sarking dependency | $22–$32 |

Costs are indicative installed ranges for typical Brisbane commercial roofs — final pricing subject to access, project scale and Section J specification.
When Anticon™ Is the Right Choice for Your Brisbane Building
Anticon is purpose-built for one application — the underside of a metal roof. It is not the right choice for
lined ceiling cavities, framed walls, or under-tile installations. The decision tree is straightforward:
if the building has a metal roof and the roof is being newly sheeted (or re-sheeted), Anticon is the default
Australian commercial specification.
Metal-Roofed Class 7b Storage Warehouses
The single largest application. Class 7b distribution warehouses, 3PL facilities, self-storage and bulk-goods
sheds across Wacol,
Yatala, and the
TradeCoast rely on Anticon as the primary roofing
blanket. Typical specification: Anticon 130 plus reflective foil sarking, hitting NCC Section J Total R3.7.
Class 8 Factory and Production Roofs
Class 8 manufacturing facilities, production plants,
and assembly sheds use Anticon to manage internal heat loads from machinery on hot days. Acoustic absorption
becomes important where staff work directly under a metal roof during summer storms — Brisbane records hail
events on tin roofs that make conversation impossible without acoustic treatment.
Class 5 / 6 Retail and Commercial Roofs
Showrooms, retail boxes, hardware stores and commercial light-industrial buildings with metal roof systems —
Class 5 office and Class 6 retail under Australian Building Codes Board
classifications. Anticon HP 130 is often specified here to hit Section J in a single layer without
relying on additional sarking.
Sheds, Workshops and Light-Industrial
Smaller-format buildings — engineering workshops, mechanical sheds, agricultural and rural-industrial structures
across the Moreton Bay corridor and outer-Brisbane
industrial fringes. Anticon 60 (R1.3) or Anticon 80 (R1.8) is typical for sub-Section-J-target sheds where
summer heat reduction is the goal rather than full commercial compliance.
Rain Noise Reduction on Metal Roofs
Brisbane’s storm season makes rain-on-metal-roof noise a recurring complaint in mezzanine offices, breakroom
areas and any occupied space directly under uninsulated tin. Anticon’s glasswool body delivers acoustic
absorption that meaningfully reduces impact-noise transmission. Thicker variants (130mm+) deliver more
acoustic benefit than thinner products.
Condensation Control in Humid Brisbane
Brisbane sits in NCC Climate Zone 2 — warm humid summer. Under-roof condensation forms when warm, humid
internal air contacts the cold underside of a metal roof in the early hours of a clear winter morning.
The water drips into bulk insulation, soaks framing timbers, and corrodes purlins. The Anticon foil face
acts as a vapour barrier between the conditioned space and the metal sheet — a Section J condensation
management measure that complements the bulk-insulation R-value.
How Anticon™ Achieves NCC 2022 Section J Total R3.7 (Climate Zone 2)
Under NCC 2022 Volume One Part J4D4,
a roof in Brisbane (Climate Zone 2) requires a minimum Total R-value of R3.7 for downward
heat flow — applied uniformly across all Classes 5–9 commercial buildings. There are two main Anticon
pathways to that target.
Pathway A — Anticon 130 + Sarking (Combined System)
- Anticon 130 material R-value: R3.0 (per Bradford datasheet)
- Reflective foil sarking system contribution: R0.7–R1.0 (depending on air gap, per AS/NZS 4859.1 framework)
- Combined Total R-value: R3.7 to R4.0 (system) once air-film and framing-bridge contributions are added
- Best for: standard-spec warehouse roofs where the additional sarking layer is straightforward to install
Pathway B — Anticon HP 130 Single-Layer System
- Anticon HP 130 material R-value: R3.6
- System contribution: air-film + minor framing contributions
- Combined Total R-value: R3.7+ (system)
- Best for: tight purlin-to-sheet clearance, single-layer specifications, projects without sarking budget, simplified Section J documentation
Pathway C — Anticon 145 (Standard, R3.6 Material)
- Anticon 145 material R-value: R3.6 (standard product, denser thickness)
- Best for: projects where standard product specification is preferred over HP, with adequate purlin clearance for the full 145mm depth
Pathway D — Anticon 175 (Maximum Standard R-Value)
- Anticon 175 material R-value: R4.2 (above the Climate Zone 2 target — useful for conditioned spaces, Climate Zone 7 projects, or future-proofed designs)
- Best for: high-spec conditioned warehouses, owner-occupied facilities seeking higher thermal performance than the NCC minimum
Important: Total R-value is a system value, not a material value. A material at R3.6 will not
automatically deliver Total R3.7 once thermal bridging through purlins, top-hat sections, and structural members
is accounted for. Insulation Guru Brisbane specifies to system targets per AS/NZS 4859.1 calculation and
provides post-install verification documentation suitable for Section J consultants
and builders at certifier hand-over.
Wacol targeting Section J Total R3.7, the standard
specification is Anticon 130 + sarking (Pathway A) at $20,000–$30,000 ex GST installed. Where single-layer
simplicity is preferred, Anticon HP 130 (Pathway B) sits in the $22,000–$32,000 range.
Anticon™ Plus the Insulation Guru System Stack
Anticon is the roofing blanket — but a complete warehouse insulation system pairs Anticon with bulk insulation
in lined-ceiling areas, sarking for combined-system R-value targets, and panel systems for cold-store zones.

(EPS-FR, PIR, XFLAM, Volcore options). Anticon covers the dry-store roof; panels cover the cold-store envelope.
For retrofit projects where the roof isn’t being re-sheeted, cellulose blow-in fills ceiling cavities without
opening up the building envelope. Made from recycled paper with borate fire/pest treatment — ideal for
warehouse-office retrofits where Anticon under the roof isn’t accessible.
closed-cell polyurethane). For projects specifying spray foam, Anticon HP 130 single-layer achieves equivalent
R3.6 with traditional, AS/NZS 4859.1 certified materials and an established CSR Bradford warranty pathway.
Anticon™ vs Spray Foam — Why We Recommend Bradford Over Polyurethane
Spray foam (open-cell or closed-cell polyurethane) is sometimes specified for warehouse roof retrofits.
Insulation Guru Brisbane does not install spray foam. For projects where spray foam has been specified, we
recommend Anticon HP 130 single-layer or Anticon 130 + sarking as equivalent traditional-material pathways.
| Attribute | Bradford Anticon HP 130 | Closed-cell spray foam (typical 75–100mm) |
|---|---|---|
| Material R-value | R3.6 | R3.6–R4.9 |
| System Total R-value | R3.7+ (Section J compliant Climate Zone 2) | R3.7–R5.4 |
| Standard certification | AS/NZS 4859.1 | Varies — manufacturer specific |
| Manufacturer | CSR Bradford (Australian, established 1934) | Various — chemistry-dependent |
| Acoustic absorption | Significant (glasswool body) | Minimal (closed-cell foam is acoustically reflective) |
| Condensation behaviour | Foil acts as vapour barrier; glasswool absorbs incidental moisture | Closed-cell impermeable — can trap moisture if compromised |
| Installation site impact | Dry install, low-VOC, no curing time | Wet chemistry, off-gas during cure, ventilation requirements |
| End-of-life | Glasswool recyclable (manufacturer take-back schemes) | Non-recyclable polyurethane, mixed-stream waste |
| Insulation Guru installs | Yes — primary specification | No — refer alternative provider |
Insulation Guru Brisbane does not install spray foam. For projects specifying spray foam, Anticon
HP 130 single-layer achieves equivalent R3.6 with traditional materials and avoids polyurethane chemistry on site.
Anticon™ Blanket vs Glasswool Batts — When to Use Which
Both Anticon and Knauf Earthwool glasswool batts are AS/NZS 4859.1 certified glasswool products from established
Australian manufacturers. They serve different parts of the warehouse envelope. The decision is driven by the
assembly: under the metal roof sheet vs above a lined ceiling.
| Decision factor | Bradford Anticon™ blanket | Knauf Earthwool batts |
|---|---|---|
| Installation location | Under metal roof sheet (over purlins) | In framed wall cavities or above lined ceilings |
| Format | Continuous roll-out blanket (limits cold-bridging) | Cut-to-fit batts (in framed cavities) |
| Foil face | Yes — polyweave-reinforced reflective foil | No — bulk insulation only (foil sarking added separately) |
| Acoustic on metal roof | Designed for rain-on-metal absorption | Not directly under metal — different acoustic role |
| Condensation control | Foil acts as vapour barrier under sheet | Requires separate sarking layer |
| R-value range | R1.3 (60mm) to R4.2 (175mm) standard; R3.6 HP130 | R1.5 to R6.0 (Knauf Earthwool range) |
| Best for | Class 7b storage, factory roofs, sheds, retail metal-clad roofs | Warehouse office areas, conditioned mezzanines, lined-ceiling fit-outs |
| Cost installed | $15–$32 / m² | $20–$30 / m² |
The Combined Specification
A typical Brisbane warehouse with attached office uses both. Anticon goes under the entire metal
roof sheet — across the warehouse floor, over the office area, over breakrooms. Knauf Earthwool batts
sit above the office lined ceiling for additional thermal performance in conditioned zones. Where polyester is
specified for amenities, Higgins R3.5 replaces glasswool above the lined ceiling. The Section J
verification pack documents the Total R-value across each zone separately.
Anticon™ Installation — Survey to Sign-Off in Four Steps
Senior installer measures roof area, identifies BCA class, confirms purlin spacing and clearance, screens
for asbestos on pre-1990 buildings, and reads from the architect’s Section J report (new build) or
generates the spec ourselves (retrofit). Anticon variant locked in at this step.
Order direct from CSR Bradford
via the GI Building Services supply chain. Lot numbers and AS/NZS 4859.1 batch certificates recorded for
the Section J compliance pack. Staged delivery so blanket isn’t exposed before sheeting.
Anticon rolled out across purlins, foil-side down, run continuously across joins with overlap to maintain
envelope continuity. Installed around your operational hours — pre-dawn, weekend or program-coordinated.
White Card holders, site-specific SWMS, full WorkSafe Queensland compliance.
Post-install verification: installed Anticon variant, Total R-value calculation, Bradford lot numbers, m²
coverage, deviations from spec. Suitable for certifier and Section J consultant hand-over. 12 months
workmanship defects period plus CSR Bradford material warranty terms.

| Warehouse roof size | Anticon 80 + sarking ($15–25/m²) | Anticon 130 + sarking ($20–30/m²) | Anticon HP 130 single-layer ($22–32/m²) |
|---|---|---|---|
| 500 m² (workshop / small shed) | $7,500–$12,500 | $10,000–$15,000 | $11,000–$16,000 |
| 1,000 m² (typical SME warehouse) | $15,000–$25,000 | $20,000–$30,000 | $22,000–$32,000 |
| 2,500 m² (mid-size DC) | $37,500–$62,500 | $50,000–$75,000 | $55,000–$80,000 |
| 5,000 m² (large DC / 3PL) | $75,000–$125,000 | $100,000–$150,000 | $110,000–$160,000 |
| 8,000 m² (greenfield distribution centre) | $120,000–$200,000 | $160,000–$240,000 | $176,000–$256,000 |
Anticon is most cost-effective when installed during new-roof installation (greenfield or roof-recover) — retrofit
under an existing metal sheet requires sheet removal and replacement, which is priced separately by the metal
roofing contractor. For retrofit projects where the roof isn’t being re-sheeted, see our
Knauf Earthwool glasswool ceiling insulation and
insulation removal pages.
