Insulation solution
Class O Armaflex materials have been selected to provide both thermal and acoustic insulation for air conditioning ductwork as part of a major restoration project at the Belfast City Hall.
Class O Armaflex materials have been selected to provide both thermal and acoustic insulation for air conditioning ductwork as part of a major restoration project at the Belfast City Hall.
Existing ductwork had not been designed to accommodate the thickness of modern insulation, which provides better thermal efficiency, and the mechanical droning sound generated by the air-handling units needed to be addressed.
The application of 1716m2 Class O Armaflex materials has successfully resolved both the thermal and acoustic problems. Internally lining the ductwork walls with 25mm thick Armaflex insulation has ensured that energy saving targets were achieved, while noise propagation generated by low frequencies through frame resonance has also been reduced to an acceptable level.
