Quadzero™ is a high performance, foil-faced, mass-loaded vinyl noise barrier, offering superior acoustic transmission loss and low spread of flame surface covering.
Quadzero™ was developed to meet market noise reduction requirements in the domestic, commercial, industrial and OEM sectors.
To achieve this high performance, the Pyrotek engineering team developed Quadzero™ to be dense, thin, strong, tear-resistant and highly flexible. These properties give the product high transmission loss throughout the various weight ranges.It complies with British and international fire and building codes for low spread of flame.
Stiff lightweight panel constructions, such as plasterboard, drywall, plywood and hollow core walls, typically have coincidence dip resonance which allows noise to transmit through a construction. The coincidence dip is dependent on the material’s stiffness and thickness and occurs at the point where the sound transmitted through the structure matches the natural frequency of the panel.
Quadzero™ shifts the coincidence dip to frequencies limiting its impact, thereby maintaining the performance of the product. The thin, dense mass Quadzero™ barrier reflects and absorbs the transmission of sound through walls, ceilings and floors, reducing the critical frequencies generated from mechanical equipment, engine noise and electronic audio devices.

Posted in:Bradford Supertel™ is designed as internal insulation for HVAC ductwork. It also has many applications as a general insulation product to enhance both thermal and acoustic performance.
Bradford Supertel is manufactured from a resilient engineered glasswool insulation blanket 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.
Supertel™ has been designed as a thermal and acoustic internal lining for all air conditioning duct work or may be used for other thermal and acoustic applications where high insulation performance is required at minimal thickness. Supertel™ comes in a range of thicknesses that meet the performance requirements as set out by the NZ Building Code.
Typical HVAC applications include:

Bradford Multitel™ is a low density lightweight insulation used for externally lining duct work.
Bradford Multitel is manufactured from an engineered glasswool insulation blanket typically faced with a reinforced foil. 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.
Multitel is a versatile flexible insulation material that is designed for the economic external insulation of heating, ventilating and cooling ductwork. Multitel™ comes in a range of thicknesses that meet the performance requirements as set out by the NZ Building Code.
Typical HVAC applications include;
Glasswool Multitel is fixed externally to duct work.
