Key Products


The FABROCK™ series was engineered specifically to stand up to the rigors of fabrication. FABROCK comes in a variety of formats, densities and dimensions, making it easy to cut, bend, split, wrap or compress. Higher air flow resistivity means better sound attenuation. FABROCK is also fire resistant, water repellent, sound absorbent; and ideal for sound dampening, across a wide range of frequencies.

Applications: Designed for fabricators and OEM equipment, for advanced products for a wide range of industries like Fire/Acoustic Doors, Office Interiors, Insulated Packaging, Appliance, Transportation, HVAC and more. 

Benefits: Fire resistant, Water repellent, and Sound Absorbent

Manufacturer: ROCKWOOL


Not only is CONROCK a key component in any assembly for fire walls or zero lot line applications, it will also provide incredible sound attenuation for a quiet environment. With similar fire performance to CONROCK, CONROCK 60 has superior acoustic properties and can be easily fabricated for use in a variety of OEM applications. CONROCK 60 is classified as a rigid board and has excellent acoustical dampening properties. Because of its density and non-directional fibre orientation it dissipates sound waves to create a quieter environment.

Ideal Applications: Insulated Metal Panels, Structurally Insulated Panels (SIPs), Acoustical Panels, Cold Rooms, Clean Rooms, Theatres, Sound Studios, Schools Auditoriums/Gymnasiums, Churches, Acoustical Partition Walls, Roadside Walls and Insulated Concrete Panels

Benefits: Non-combustible, Sound Absorbent, Moisture resistant, Easily fabricated, Stable long-term thermal performance, and Dimensionally stable.

Manufacturer: ROCKWOOL


CAVITYROCK is a semi-rigid, mineral wool insulation board designed for exterior cavity wall and rainscreen applications.

CAVITYROCK is non-combustible and fire resistant, and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. Approved for use in many NFPA 285-compliant designs, it is an important component of fire-resilient exterior wall systems when used as a continuous insulation. CAVITYROCK also offers long-term thermal efficiency, moisture control and acoustic performance – improving the energy efficiency and comfort of buildings. Choose mono-density insulation in thicknesses up to 2” or dual-density in thicknesses of 2.5” to 6”.
