The PIRALU ducts
Piralu®
is a panel of pure embossed aluminium preinsulated with a Polyisocyanurate (PIR) foam and used in the
construction of ducting for air distribution in heating, ventilation
and air-conditioning systems (HVAC).
With these Piralu® pre-insulated panels an extremely high quality ducting can be
achieved, as a direct result of the combination of the aluminium and of excellent
insulation (PIR). This combination also provides and excellent internal air quality
(IAQ), a fine external finish, longlife material, lightweight and easily transported,
manipulated and constructed.
