ALSDL-L Flexible Ventilation Duct with Thermal and Acoustic Insulation
ALSDL-L
ALSDL-L Flexible Ventilation Duct
The thermally and acoustically insulated ALSDL-L duct protects air in ventilation systems from cooling down, while also acting as a sound attenuator due to its additional perforation. Constructed from an Aluduct base with 25 or 50 millimeter insulation and an aluminum-polyester jacket, it is ideal for use with supply air plenums, valves, and in quick recuperation system installations.
