## Summary description

THERMAFLEX THERMAWOOL 28/20 is a mineral wool thermal insulation in a 1 meter roll (DWZ). Designed for thermal and acoustic insulation of pipes, ducts or equipment, it provides fire-resistant, non-combustible fibrous insulation with stable thermal performance. Suitable for commercial and residential HVAC, plumbing and industrial applications where mineral wool pipe insulation is required.

## Long description

THERMAFLEX THERMAWOOL 28/20 mineral wool in a 1 m roll (DWZ) is a fibrous thermal insulation product designed for pipe, duct and equipment insulation. The product combines mineral wool's inherent fire resistance and stable thermal performance to reduce heat loss and limit noise transmission in HVAC, plumbing and industrial installations. Supplied in a roll format, the insulation is suitable for cylindrical surfaces and can be cut to length for specific applications.
Advantages
Mineral wool composition provides non-combustible insulation with consistent thermal resistance across a range of operating temperatures. The roll format allows for flexible installation around pipes and irregular surfaces and facilitates on-site cutting and shaping. The material offers combined thermal and acoustic performance, and it maintains dimensional stability and long-term insulation properties when installed correctly.
Suitable for
Thermal insulation of hot and cold water pipes in residential and commercial buildings
Insulation of HVAC ducts and mechanical equipment to reduce heat loss and noise
Industrial piping systems requiring fire-resistant insulation
Renovation projects where preformed rigid segments are impractical
Key specifications
Material: mineral wool (stone wool)
Format: 1 meter roll suitable for wrapping around pipes and ducts
Thickness/profile: 28/20 (nominal dimensions describing roll geometry and wall thickness)
Thermal performance: stable thermal conductivity typical for mineral wool insulation used in building services
Fire performance: non-combustible fibrous insulation
Acoustic properties: reduces noise transmission along pipes and ducts
How to use
Measure the length of pipe or duct to be insulated and unroll the THERMAWOOL to the required length. Cut the roll with a suitable knife or insulation cutter to match the diameter and length of the service. Wrap the mineral wool around the pipe or duct ensuring full contact and consistent coverage, then secure the insulation with bands, tape or cladding as appropriate for the application. For joints and terminations, ensure tight fitting and use suitable sealants or collars if required to maintain thermal continuity and fire performance.
Usage recommendations
For optimal performance, select a thickness and installation method compatible with the operating temperature and environmental conditions of the installation. Use protective outer cladding or vapor barriers where condensation, weather exposure or mechanical damage is possible. Follow local building regulations and safety guidance for handling mineral wool, including the use of gloves and eye protection during cutting and fitting.
