Fire-Rated Insulation
Fire-Rated Insulation Products For Homes And Buildings
Fire-rated insulation products are supplied for use in building systems where improved fire performance and safety are required. These insulation products are commonly specified in residential, commercial, and industrial buildings to help limit fire spread while also contributing to thermal and acoustic performance.
Fire-resistant insulation is used in applications where insulation materials must maintain stability under high temperatures and not contribute to flame development. In regulated environments, fire-rated insulation plays a critical role in overall building safety and compliance.
This page focuses only on fire-rated insulation products, allowing buyers to select insulation materials designed to meet fire performance requirements.
How Fire-Rated Insulation Products Are Used
Fire-rated insulation products are supplied in batts, boards, or rigid formats and are designed for use within walls, floors, ceilings, and roof systems. When installed as part of a building assembly, fire-resistant insulation helps reduce the spread of fire while supporting thermal efficiency and sound control.
Fire-rated insulation is commonly used in:
- Wall and partition systems
- Floors and ceilings between occupied spaces
- Roof assemblies and service areas
- Commercial and higher-risk building applications
The suitability of fire-resistant insulation depends on building design, fire safety requirements, and applicable regulations.
For applications requiring the highest level of fire resistance, rockwool insulation is the preferred choice. Rockfibre stone wool boards are non-combustible, A1 fire-rated and specifically designed for fire-rated wall and ceiling systems.
Understanding A1 Fire-Rated And Non-Combustible Insulation
A1 fire-rated insulation refers to insulation products classified as non-combustible under recognized fire testing standards. Non-combustible insulation does not ignite, contribute to flame spread, or release significant heat during a fire.
A1 fire-rated insulation products are commonly specified in:
- Multi-storey buildings
- Commercial and public buildings
- Fire separation walls and floors
- Areas with strict fire safety requirements
Using non-combustible mineral wool insulation helps meet fire-resistance standards while maintaining insulation performance.
Types of Fire-Resistant Insulation Materials
Fire-rated insulation products are manufactured using materials designed to achieve high fire-resistance performance. Fire rating depends on both material composition and certified fire classification.
Non-Combustible Mineral Wool Insulation
Mineral wool insulation (stone wool) is widely used as fire-resistant insulation due to its:
- Fully non-combustible composition
- Very high temperature resistance
- Stable performance during fire exposure
Mineral wool products are commonly selected where maximum fire resistance is required.
A1 Fire-Rated Glasswool Insulation
Glasswool insulation products are manufactured and tested to achieve A1 fire-rated classification. When certified as A1, glasswool insulation is considered non-combustible and suitable for fire-resistant building applications.
A1 fire-rated glasswool insulation offers:
- Proven fire resistance
- Effective thermal and acoustic performance
- Lighter handling compared to mineral wool
Only glasswool products with certified A1 classification should be used in fire-rated applications.
Fire-Resistant Insulation Thickness And Performance
Fire-resistant insulation performance is influenced by:
- Insulation thickness
- Material density
- Application within the building system
Thicker insulation products can improve thermal performance while maintaining fire-resistant properties. Selecting the correct product depends on fire-rating requirements, insulation goals, and building design.
Fire-Rated Insulation Prices – What To Expect
Fire-rated insulation prices vary based on:
- Fire-resistance classification
- Material type and density
- Insulation thickness
- Product specifications
Fire-resistant and A1 fire-rated insulation products typically cost more than standard insulation materials due to their non-combustible properties and fire performance requirements. Product pricing is displayed on the product listings above and on individual product pages, allowing buyers to compare options based on performance and budget.
