ROCKWOOL® Ductslab
BSI Kitemark
Certificate type
Thermal insulation for rectangular, square and circular ductwork.
Application
In order to regulate temperature within heating, ventilation and air conditioning systems insulation must be applied. ROCKWOOL Ductslab can provide the thermal insulation to these HVAC systems as well as cold water storage, feed and expansion tanks. This solution is acoustically absorbent and A1 non-combustible to deliver peace of mind.
Description
Ductwrap is a lightweight and flexible insulation roll faced with reinforced aluminium foil.
Ductwrap is suitable for both circular and rectangular ductwork. This solution is recommended for service temperatures of up to 230˚C. The thermal insulation solutions are often applied to air conditioning, warm air and extractor ducts, located in plant rooms, boiler houses or externally.
In addition to its thermal properties, the mineral wool insulation delivers acoustic performance which can be desirable for applications to ducts that carry gases, fluids or particle solids at high velocities. The use of ROCKWOOL Ductslab can also significantly improve the level of environmental sound, for a far more pleasant working environment.
