Application
ISO+ (Insulated Flexible Duct) is a range of fully flexible thermally insulated ducting, which has been specially designed for the HVAC market. The ISO+ range has been developed to minimise the heat gain or loss resulting from the temperature difference between the air flowing in a duct and the surrounding air. The vapour barrier prevents condensation forming on the outside of ducts carrying air at lower temperatures than the surrounding air.

Construction
ISO+ consists of one of the ALU+ innerducts, 25 mm thick fibreglass insulation and is covered with either a vapour barrier outerjacket or one of the ALU+ ducts.
The JACKET+ used is either a spirally produced multi-layer Aluminium/Polyester Laminated Construction or a Metalized Polyester Jacket.
Since all the individual components of the ISO+ products are assembled at the production plant, you can make your own combination you need for your application. Already a selection has been made as described underneath.
Options for fiberglass: yellow, red, white.
