Fireproof Insulation

Adaston provides specialist fireproof insulation installation services designed to enhance fire safety and improve the overall fire performance of buildings. We work with proven, industry-approved materials to deliver reliable passive fire protection for domestic, commercial, and industrial buildings, meeting all current UK building regulations.

What Is Fireproof Insulation?

Fireproof insulation is a type of fire resistant insulation used to limit the spread of fire and protect the structure of a building. Typically made from non combustible materials such as stone wool and mineral wool, it provides excellent fire resistance and insulation performance.

When professionally installed, fireproof insulation maintains its strength and integrity at high temperatures, helping to prevent flames and toxic smoke from spreading through walls, floors, and ceilings.

This type of passive fire protection helps maintain fire safety and compliance by protecting escape routes and structural elements. It is a vital part of any complete fire protection strategy, supporting the performance of other fire stopping products used throughout a building.

Non-Combustible and Fire Rated Materials

Adaston installs A1 non combustible insulation products sourced from leading manufacturers to deliver exceptional fire resistance and proven reliability. Our solutions include rock wool fire insulation, stone wool slabs, and mineral wool batts that are specifically selected for fire protection applications.

Rock wool insulation is a non combustible material derived from volcanic rock, melted and spun into durable fibres. When installed correctly, it provides outstanding fire resistance, producing no flaming droplets and minimal smoke. With a high rockwool fire rating, it ensures long-term protection for a variety of construction types.

Stone wool offers similar benefits, providing both thermal insulation and acoustic performance. It can withstand high temperatures without losing shape, helping maintain fire performance in walls, floors, and ceilings. These fire rated insulation materials meet the highest classifications of non combustible insulation and contribute to the overall passive fire protection of the structure.

Fire Stopping, Fire Barriers and Cavity Solutions

Effective fire stopping prevents the spread of flames and hot gases between compartments within a building. As part of our service, Adaston installs a wide range of fire stopping products, cavity barriers, and cavity stop socks that create effective seals around penetrations and voids.

Our fire barrier systems incorporate non combustible insulation materials to maintain the structural integrity of compartment walls and floors. Cavity barriers are designed to stop the passage of flames, heat, and toxic smoke through concealed spaces, helping ensure compliance with fire safety regulations.

Cavity stop socks and fire barriers are available in standard x 1200 mm slab sizes for efficient installation and complete coverage. These components are essential in cavity wall and floor systems, ensuring that fire protection and thermal insulation are maintained throughout the building.

Passive Fire Protection Systems

Passive fire protection is an integral part of any building’s safety strategy. Adaston delivers fireproof insulation as part of a wider passive fire protection service, providing systems that work automatically, without the need for activation.

By incorporating fire resistant insulation materials into the fabric of a building, we help ensure built-in fire resistance that enhances overall fire safety.

The materials we install have been tested for fire performance and meet the latest building regulations. Fireproof insulation materials like stone wool and rock wool provide inherent protection against fire spread and heat transfer. These systems support the performance of other fire stopping measures such as cavity barriers, ensuring that the structure remains stable during a fire event.

Fire Performance and Testing

Adaston specifies and installs fireproof insulation that has been tested under rigorous conditions to verify fire resistance and durability. Each product we use is subjected to fire tests that simulate real building fires to ensure compliance with UK standards.

Fire rated insulation achieves A1 or A2 classifications, meaning it is completely non combustible and will not contribute to fire growth. During testing, materials are assessed for resistance to high temperatures, production of smoke, and maintenance of insulation performance.

These extensive tests confirm that the non combustible insulation we install delivers long-term fire safety and thermal performance across a wide range of applications.
