DESCRIPTION
Rockwool board insulation is a type of rigid insulation made from spun mineral wool, which is derived from a mixture of volcanic rock and slag.
It is known for its high thermal resistance, soundproofing capabilities, and fire-resistant properties, making it a popular choice for insulation in a wide range of applications.
ROCKAL Boards are especially rigid than other ROCKAL Rockwool products and comply with ASTM C-612.
APPLICATION
- Wall insulation - Used to insulate both residential and commercial buildings, rockwool board insulation provides a continuous layer of insulation in walls, improving the overall energy efficiency of the building.
- Roof insulation - It is used to insulate roofs, including pitched and flat roofs, to prevent heat loss and reduce energy costs.
- Floor insulation - Rockal Rockwool board insulation is also used to insulate floor systems, particularly in commercial buildings where soundproofing is important.
- HVAC systems - Rockal Rockwool board insulation is commonly used to insulate heating and cooling ducts, reducing heat loss and improving energy efficiency.
Facing
ROCKAL Rockwool Boards can be non-Faced or faced with reflective vapor barrier material (Reinforced Aluminum Foil FSK) or Kraft Paper, fiber glass tissue BGT or BGF.
Advantages
- Fire resistance - Rockal Rockwool board insulation has excellent fire resistance, making it an ideal choice for areas where fire safety is a concern.
- Soundproofing - Rockal Rockwool board insulation provides excellent soundproofing properties, making it a great choice for noisy areas like theaters, recording studios, and multi-unit dwellings.
- Durability - Rockal Rockwool board insulation is long-lasting, durable and does not deteriorate over time, making it a cost-effective solution for insulation.
- Moisture and mold resistance -Rockal Rockwool board insulation is resistant to moisture and mold growth, making it a suitable choice for areas with high humidity or damp conditions.
- Environmentally friendly - Rockal Rockwool board insulation is made from sustainable and renewable materials and can be recycled, making it an environmentally friendly choice.
- Easy installation - Rockal Rockwool board insulation is easy to install, making it a popular choice for both contractors and DIY enthusiasts.
