Stone Wool

“Exceptional A1 fireproof insulation with unbeatable price-to-performance. Known globally as Mineral Wool, Stone Wool, Earthwool, or Rockwool – the perfect solution for your needs!”

Description

“Stone Wool insulation, available in both board and blanket forms, is made from mineral rock fibers derived from volcanic basalt rocks and slag. During production, the raw materials are melted at high temperatures and spun into fibers, which are then bound together using a thermosetting binder to form rigid boards or flexible blankets. The boards offer durability and resilience, while the blankets are designed for easy application and flexibility. Both forms provide excellent thermal and acoustic insulation, making them ideal for a wide range of commercial and industrial applications.”

Application Area

Stone Wool Board
(Rigid & Semi-Rigid Panels)

Exterior & Interior Wall Insulation – Used in cavity walls, partition walls, and curtain wall systems for thermal and acoustic insulation.
Roof Insulation – Applied in flat and pitched roofs for heat retention and fire resistance.
Ceiling Insulation – Used in drop ceilings for soundproofing and thermal efficiency.
Fire Protection – Commonly used in fire-rated walls, doors, and enclosures due to its high fire resistance.
HVAC & Duct Insulation – Provides thermal and acoustic insulation in duct systems.
Industrial & Marine Applications – Used in factories, power plants, and ships for fire safety and thermal insulation.
Mechanical Equipment Insulation – Protects boilers, furnaces, and other high-temperature machinery.
Basement & Garage Insulation – Installed on walls and ceilings to improve energy efficiency.

Stone Wool Roll
(Flexible Blanket)

Loft & Attic Insulation – Ideal for laying between rafters and joists in attics.
Floor Insulation – Used under suspended floors to reduce heat loss and dampen sound.
Partition Walls & Stud Walls – Provides easy-to-install soundproofing and thermal insulation.
Pipe & Ductwork Wrapping – Flexible enough to wrap around HVAC ducts and plumbing pipes.
Metal Building Insulation – Applied in steel structures for sound absorption and temperature control.
Soundproofing in Recording Studios & Theaters – Used as an acoustic barrier in sound-sensitive areas.
Cavity Wall Insulation – Installed between wooden or metal frames in building structures.
