K-flex K-ROCK ALU mineral wool insulation with aluminum jacket 30 x 60 mm, 1 m stick

K-flex K-ROCK ALU mineral wool insulation with aluminum jacket 30 x 60 mm, 1 m stick is a tubular thermal and acoustic insulation designed for pipes and equipment. It combines a non-combustible mineral wool core with a tough aluminum outer jacket to deliver fire-resistant thermal protection, sound attenuation and mechanical durability in HVAC, plumbing and industrial installations.

Advantages

The mineral wool core provides high-temperature stability and fire resistance while offering good thermal performance. The aluminum jacket protects the insulation from moisture, mechanical damage and external contaminants and facilitates easy cleaning. The tubular shape and 1 m stick length enable straightforward installation on straight pipe runs and offer a neat finish with reduced on-site cutting time.

Suitable for

• Thermal insulation of hot and cold water pipes
• Acoustic insulation to reduce pipe-borne noise
• Fire-resistant insulation in HVAC ductwork and plant rooms
• Industrial piping and equipment requiring mechanical protection

Key specifications

• Material: mineral wool core with aluminum outer jacket
• Shape: tubular section (pre-formed pipe insulation)
• Dimensions: 30 mm inner diameter / 60 mm outer diameter profile
• Length: 1 metre per stick
• Core properties: non-combustible, high temperature resistance, sound absorption
• Jacket properties: corrosion-resistant aluminum, easy to clean, mechanical protection

How to use

Select the correct diameter and length for the pipe run, then open the pre-formed tubular section and fit it around the pipe, aligning the split along the underside where possible. For continuous runs, butt adjoining sticks together and seal seams with appropriate high-temperature tape or approved sealant compatible with aluminum jackets. Ensure joints, bends and fittings are insulated by cutting and shaping pieces to maintain continuous coverage. Follow local building codes and safety guidance for working near heat sources and during installation in confined spaces.

Usage recommendations

For optimal performance, verify compatibility of sealing materials with aluminum jackets and use mechanical fastening or aluminum-compatible tape at joints. Inspect installed insulation periodically for jacket damage or moisture ingress and replace compromised sections to maintain thermal and fire performance.
