Jet Stream Max
Jet Stream Max is a soft, granulated mineral wool thermal and acoustic insulation, manufactured in selected North American plants by melting and spinning a blend of inert, natural minerals. It has all the advantages of glasswool batting materials without the inherent installation disadvantages, so achieves superior installed performance. It is the only formaldehyde free, non-combustible, clean and durable blown insulation that has been used to insulate New Zealand roof attics since 1995. |
Jet Stream Max installerPremium quality Jet Stream Max forms a consistent white layer similar to cotton wool in accessible roof attics. It eliminates energy wasting gaps, joints or vented cavities between the insulation and lining common with blanket or batting.
Total (installed) thermal effectiveness of Jet Stream Max is superior to batting or blanket, as it covers the full ceiling – including over and under timber joists – without joints, gaps, thermal bridging, or vented cavities commonly found between linings and batting or blanket insulation.
Batting or blanket materials need at least two layers to achieve the same installed thermal effectiveness of Jet Stream Max that only requires simpler installation of the design thickness and weight.

Underfloor Insulation
|
Mammoth Modern Insulation
Underfloor insulation warms your home by reducing draughts and heat loss. Heat loss through an uninsulated floor is estimated at 12-14%* and, if you have sufficient crawl space under your floor, adding insulation is a cost effective way to create a warmer, healthier home. Mammoth underfloor insulation is made from 100% polyester fibres and does not deteriorate with moisture resistant and unlike polystyrene insulation won't affect electrical wiring.
