Product Description

About Ultratel™ 48kg/m³ Enviroduct HVAC Range

Bradford Ultratel™ is designed as a high performance internal insulation on HVAC ductwork . It also has many applications as a general insulation product to enhance both thermal and acoustic performance.

Bradford Ultratel™ is manufactured from a rigid engineered glasswool insulation typically with an appropriate facing. The blanket is manufactured by spinning  molten glass, containing up to 65% recycled content, into fine wool like fibres. These are bonded together using a thermosetting resin. The product can be identified by its golden appearance.


Ultratel™ is designed to provide high performance internal insulation of heating, air conditioning and cooling ducted systems. Ultratel™ delivers superior sound absorption and attenuation due to its higher density and rigid properties.
