"Insulate with Confidence
for Tomorrow, Today"


Rockwool Prime is a premium insulation product offered by Rockwool, a leading manufacturer of stone wool insulation solutions.


Rockwool Prime is specifically designed to provide superior thermal performance, fire resistance, sound absorption, and moisture resistance for various residential and commercial applications.


Here are some key features and benefits of Rockwool Prime:


  1. Superior Thermal Performance: Rockwool Prime insulation effectively reduces heat transfer through walls, floors, and ceilings, helping to maintain a comfortable indoor temperature year-round. Its high-density composition and unique fiber structure minimize thermal bridging, ensuring maximum energy efficiency and thermal comfort.

  2. Fire Resistance: Rockwool Prime is inherently non-combustible and can withstand temperatures up to 1,177°C (2,150°F). This exceptional fire resistance makes it an ideal choice for fire-rated assemblies and applications where fire safety is paramount, providing peace of mind and protection against fire hazards.

  3. Sound Absorption: With its dense and porous structure, Rockwool Prime effectively absorbs sound waves, reducing noise transmission between rooms and floors. Whether used in residential or commercial buildings, Rockwool Prime helps create a quieter and more comfortable indoor environment by minimising noise pollution.

  4. Moisture Resistance: Rockwool Prime is engineered to repel moisture and resist the growth of mold, mildew, and bacteria. Its hydrophobic properties make it suitable for use in damp or humid environments such as basements, crawl spaces, and exterior walls, helping to maintain indoor air quality and prevent moisture-related issues.

  5. Durable and Long-Lasting: Rockwool Prime is highly durable and resistant to compression, sagging, and degradation over time. Its robust construction ensures that it maintains its thermal and acoustic performance for the life of the building, reducing the need for frequent replacements and maintenance.

  6. Environmentally Friendly: Made from natural stone and recycled materials, Rockwool Prime is a sustainable and environmentally friendly insulation solution. It is free from harmful chemicals and volatile organic compounds (VOCs), making it safe for occupants and the environment.
