Terra Lana Natural Wool Insulation

About Terra Lana Insulation

Terra Lana wool blend insulation gives superior performance with wool’s ability to ‘breathe’ making it a more efficient insulator. This means your home is warmer in winter and cooler in summer, healthier and more environmentally responsible.


  • Ceilings, walls and floors
  • New and retrofit
  • Residential and commercial buildings


The wool in Terra Lana natural wool blend insulation is a carefully selected mixture of clean, recycled fibre from textile mills and new sheep’s wool. The wool is blended with polyester melt bond fibre and thermally bonded to form a dimensionally stable structure. It varies in colour from light to dark grey and can be supplied in slab or roll form.


Can be ripped and fitted using bare hands without cutting tools. If cross grain cuts are required, heavy scissors, blade, or shears will suffice. Does not require stapling.


Natural Benefits

The complex design of wool fibre has properties and advantages you won’t find in synthetic insulations, offering real benefits to your home and environment.


  • Breathes
    The ability of wool to temporarily absorb atmospheric moisture helps warm cool space and cool hot spaces.As humidity is regulated this helps prevent moisture buildup, reducing condensation and moulds.
  • Healthier
    Being natural, our wool blend insulation is free of harmful substances and effects.As well as helping create healthier air space, wool also absorbs close to 100% of exposed toxins such as formaldehyde, emitted from common building and furnishing materials.
  • Safer
    Non-irritant, non-allergenic, non-toxic and odourless. Contains no harmful substances. Requires no protective clothing or masks to install.
  • Durable
    Maintains its loft with natural crimp and fibre texture and therefore will continue to entrap air for the lifetime of the dwelling.

    Literally absorbs noise from both outside the building and within the premises. Its high Flow Resistance rating means it is suitable for specialized sound control in a wide range of applications.
  • Eco Friendly
