## Long description

Rockwool Otulina 800 80/89 (DWZ) is a mineral wool insulation sleeve engineered for thermal and acoustic insulation of circular pipes. Made from stone wool, the sleeve combines heat retention, fire resistance and moisture tolerance to protect pipework in heating, plumbing and ventilation systems. The 80/89 size fits pipes within the specified diameter range and is produced for straightforward installation in commercial and residential applications.
Advantages
The mineral wool composition provides stable thermal performance and effective acoustic dampening while maintaining non-combustible behaviour. The sleeve resists moisture absorption and retains insulating properties over time. Its cylindrical shape and pre-formed geometry simplify fitting around pipes and reduce on-site cutting. The product is compatible with common pipe materials and supports energy efficiency by reducing heat loss.
Suitable for
Thermal insulation of hot and cold circular pipes in heating systems
Acoustic insulation to reduce pipe-borne noise in ventilation and plumbing
Fire-resistant insulation in mechanical plant rooms and service shafts
Insulation in residential and commercial buildings where moisture tolerance is required
Key specifications
Material: stone wool (mineral wool)
Shape: pre-formed cylindrical sleeve for circular pipes
Size: 80/89—designed for corresponding pipe diameters
Properties: thermal insulation, acoustic dampening, non-combustible
Moisture behaviour: low water absorption and moisture-tolerant
How to use
Measure the external diameter of the pipe to confirm compatibility with the 80/89 sleeve. Position the pre-formed sleeve around the pipe, aligning the split (if present) and ensuring full contact with the pipe surface. Where necessary, join sleeves end-to-end for continuous coverage and secure seams with appropriate tapes or mechanical fasteners recommended for mineral wool products. Ensure fittings, valves and flanges are either insulated with suitably shaped pieces or left accessible according to maintenance requirements. Follow applicable building codes and safety practices during installation.
Usage recommendations
Store rolls and sleeves in a dry, ventilated area prior to installation. When cutting or fitting, use personal protective equipment such as gloves, eye protection and a dust mask to avoid irritation from mineral wool fibres. For long-term performance, verify that joints are sealed and that the installation is not exposed to continuous liquid water. Consult local regulations for firestopping and service penetration sealing where required.
