Product Details

RockAir is a ROCKWOOL stone wool product for roof insulation. It is manufactured from molten natural rock spun at high speeds into soft, fibrous mats with numerous air pockets, providing excellent thermal and acoustic insulation properties.

Key Features of RockAir Insulation

  • Thermal Insulation: Stone wool has low thermal conductivity, effectively reducing heat transfer from the roof into the building.
  • Acoustic Protection: The open-cell structure with porous air pockets provides high sound absorption and noise reduction.
  • Lightweight: RockAir is a low-density stone wool insulation weighing only 1.5 kg/m², making it safe and cost-effective for structural requirements.
  • Water Repellent: Designed for under-roof installation where water exposure is possible, this insulation is developed to be non-hygroscopic, allowing water to evaporate naturally.
  • Eco-Friendly: Made from rock, it can be recycled or disposed of via landfill, where the material will naturally decompose.
  • Fire Protection: All ROCKWOOL insulation models are tested as non-combustible materials according to EN13501-1 standards.

Product Size: 1200 x 5000 mm

What is ROCKWOOL RockAir?

RockAir is a high-quality stone wool product from ROCKWOOL. Made from natural volcanic rock spun into highly flexible fibers, it is designed to be lighter than general industrial models. This makes it easy to install in residential buildings, offices, and factories while maintaining international standards for fire and thermal performance.

 

Key Features That Set RockAir Apart

  1. Superior Thermal Comfort

With a low thermal conductivity (k-value), RockAir blocks solar heat hitting the roof from entering the building, significantly reducing internal temperatures and saving on air conditioning electricity costs.

  1. Acoustic Excellence

The uniform density of the stone wool fiber structure reduces external noise, especially the sound of rain hitting metal sheet roofs.

  1. Fire Resilience

The most prominent feature of ROCKWOOL stone wool is that it is non-combustible. It can withstand temperatures exceeding 1,000°C without producing toxic smoke, increasing evacuation time and preventing the spread of fire in emergencies.

  1. Environmentally and Occupant Friendly
  • Sustainability: Made from natural rock and 100% recyclable.
  • Durability: Does not degrade over time, is not a food source for termites or insects, and does not develop mold.

Applications

RockAir is designed for versatile use in modern construction:

  • Roofing: Installed under metal sheets, roof tiles, or ceilings.
  • Drywalls: Inserted into gypsum or wooden wall cavities for room partitioning and soundproofing.
  • Office Buildings: Used in building renovations to improve energy efficiency.

 

Professional Installation Guide for RockAir

For maximum efficiency, install according to the following steps and safety standards:

Preparation Steps

  1. Ensure the installation area is dry and clean.
  2. Wear basic protective equipment such as gloves, masks, and long-sleeved shirts (to reduce direct fiber contact).

Under Purlin Installation Steps

  1. Measurement: Measure the gaps between roof purlins.
  2. Cutting: Use a knife or saw to cut the insulation 1-2 cm wider than the gap to ensure a tight friction fit and prevent thermal bridges.
  3. Securing: For high roofs, use wire mesh or insulation hangers for support to prevent long-term sagging.
  4. Joints: Ensure that joints between insulation sheets are as tight as possible.
