Mammoth Duct Liner is designed to absorb noise and thermally insulate HVAC ducts.
The polyester liner ensures the reduction of sound transfer along the duct and that air of the desired temperature is delivered at the outlets. Mammoth® Duct Liner comes in a plain white sheet or a white sheet with a black face. Mammoth Duct Liner is a semi rigid board made in New Zealand from 100% thermally bonded polyester fibres. The polyester conjugate fibre used is crimped giving excellent durability.
Mammoth's acoustic range also includes Wall Sections, Wall Blankets, Bafflestack and Panel Absorber insulation.[/vc_column_text][/vc_column_inner][vc_column_inner width="1/2"][vc_gallery type="flexslider_slide" interval="3" images="6893,6892,6891" img_size="540x390" el_class="productzoom-icon"][/vc_column_inner][/vc_row_inner][vc_row_inner content_placement="middle" el_class="properties-section" css=".vc_custom_1735012328445{padding-top: 100px !important;}"][vc_column_inner width="1/2"][vc_single_image image="8618" img_size="full"][/vc_column_inner][vc_column_inner width="1/2"][vc_column_text el_class="image-width-text-content"]
Product Properties
Mammoth Duct Liner (previously NOVAhush) is supplied plain and can have perforated foil or plain foil applied.
Independent testing shows that Mammoth Duct Liner gives exceptional performance at the low end frequencies (125 - 500 Hertz).
Absorbs fan drumming noise and reduces speech transference from room to room between air conditioning outlets.
The thermal qualities eliminates the need to insulate the exterior of the ducting.
Mammoth Duct Liner will not shed particles (fibre fall-out) or delaminate under high air flow velocities - ensuring the airstream remains clean.
Assists in absorbing noise to create a quieter environment.
The product is not conducive to fungal bacteria growth.
Unaffected by moisture, Mammoth insulation will continue to perform once dried out.
Mammoth is moisture, mould and mildew resistant.
When installed to the manufacturer’s instructions it will remain in place ensuring the thermal effectiveness of the installed system.
Safe, non-itch, odourless and non-toxic - no precautions are required for handling the product.
Lightweight and easy to handle - can easily be cut using wide blade craft knives or specialised insulation saws.
Heat bonded - no glues or binders that can break down so it won't sag or settle over time.
Red List Free - no formaldehyde or pesticides added.
NZ Green Building Council approved.
Long lasting, Mammoth insulation is performance warranted for 50 years (T&Cs apply).
Mammoth 100% insulation products have an Ozone Depleting Potential (ODP) of zero.
Mammoth products are made in a zero waste production process and are fully recyclable.
Manufactured by InZone Industries Ltd, NZ's first and only Toitū net carbonzero certified insulation manufacturing organisation.
Materials composed entirely of polyester are regarded as non-corrosive and are exempt from testing. Alkalinity of pH 7.8.
Vermin Resistant
Not a food source for vermin (and not treated)
