Description
Natural Wool Insulation
Woolen insulation from Terra Lana outperforms fiberglass insulation in nearly every aspect. Some of the key advantages include:
- A natural wool product that is cost-effective, safe, and eco-friendly.
- Using sheep’s wool ensures it is a naturally sustainable and renewable material.
- There is no danger to your health and it breaks down naturally at the end of your home’s life.
- Most of the wool used is recycled waste wool from carpet and textile manufacturers.
Natural Wool Insulation vs Fibreglass Insulation
Whichever way you look at it, natural wool insulation is a superior product.
Natural Wool Insulation
Breathes
Yes. Actively warms cool spaces by adsorbing moisture and releasing energy. Cools warm spaces by releasing moisture and absorbing energy
Condensation
Wool absorbs and desorbs moisture thus helping to prevent condensation.
Safe to Install
Yes. Non-irritant, non-allergenic, non-toxic. Can be installed with bare hands.
Durable
Yes. Wool’s crimp and fibre scales enable it to maintain it’s loft and effectiveness over time.
Filters toxins
Naturally traps substances like nitrogen dioxide, sulphur dioxide and formaldehyde.
Biodegradable
Yes. Decomposes naturally and safely.
Low embodied energy
Yes. Only a small amount of energy is required for production.
Fibreglass Insulation
Breathes
No. Man made fibres do not breathe.
Condensation
Fibreglass fibres do not absorb and desorb moisture.
Safe to Install
Fibreglass requires protective clothing, including gloves.
Durable
No. Fibreglass inslation tends to break down/slump over time, reducing it’s effectiveness.
Filters toxins
Breathes
No. Man made fibres do not breathe.
Breathes
No. Man made fibres do not breathe.
Breathes
No. Man made fibres do not breathe.
Thermal Insulation – How It Works
Thermal Insulation stops the movement of heat. Heat likes to move from warm zones to cool zones as it tries to even the temperatures in both areas. This means in winter the hot air inside your home tries to escape outside where it is colder. In summer hot air tries to move inside where it is cooler.
About 10% of a home’s heat can be lost through the floor, 24% through the walls, and a whopping 42% through the ceiling. Thermal Insulation provides a barrier to stop this heat loss.
Typical heat loss from an uninsulated house
Most thermal insulation products make use of air because still air is such a good insulator. Terra Lana thermal insulation works by trapping millions of tiny pockets of air inside it. This trapped air is held still and not allowed to move to create an extremely effective barrier to heat transfer.
Tested & Proven
Terra Lana’s ceiling insulation, wall insulation, and underfloor insulation products were developed and tested by the Wool Research Organisation of New Zealand (WRONZ, now AgResearch) a world authority on the treatment and processing of wool.
Terra Lana’s core products have been appraised by the Building Research Association of New Zealand (BRANZ). Terra Lana produces other products in the range with different sizes and R Values but all are manufactured using the same raw materials and manufacturing
