Testing: thermal images

  • Window installation with excellent sealing work

internally and externally.

  • No notable ingress of cold air or moisture into the

walls

  • The junction between the side and rear wall

(adjacent to the patio door) demonstrates almost no corner effect at all

  • A result of the interlocking block design and the

coating used to seal the surface.

“E4 at BRE is probably the most energy efficient example that we have seen in over 8 years of thermal imaging surveys.”

Natural Insulation The Positive Impacts

Insulation Priorities

slide-38
SLIDE 38

Common Natural Fibres

Annual production of commercially significant fibres >36 mmt p.a. (excl. Wood, straw, paper) = 60+ mmt CO2 sequestered

slide-39
SLIDE 39

What’s Good for Insulation

Need to be affordable and readily available

slide-40
SLIDE 40

What’s Good for Insulation

Fibres need to be fine

slide-41
SLIDE 41

What’s Special About Natural Fibres

Irregular Fine Durable Renewable

Individual properties provide performance but performance is enhanced when properties work together. For example: Fine fibre = high internal surface area combined with breathability = extremely large breathable surface = efficient moisture control. Renewable fibres = carbon sequestration combined with durability = larger carbon sink.

Breathable

slide-42
SLIDE 42

Breathability

  • Natural fibres bind water vapour through hydrogen bonding.
  • Unlike oxygen, nitrogen and CO2 in air, water molecules are polar meaning

they can bind charges sites on the natural fibre molecule.

  • No liquid water involved. Water is constantly bound as water of hydration

and released as water vapour (gas).

  • Process is driven by the fibre trying to achieve an equilibrium moisture

content (emc) with surrounding air

  • emc is achieved when fibre is not losing or gaining water
  • As relative humidity (RH) increases fibre needs to reach a higher emc and

vice versa. Water of Hydration Water Vapour

slide-43
SLIDE 43

Breathability

  • emc varies very little with temperature so its ability to absorb

and release moisture is almost entirely dependent on the RH

  • f the surrounding air.
  • E.g. @ 70% RH the emc of wool is 17% at 25oC and 5oC
  • Over the same temperature range the amount of water vapour

air can hold @ 70% RH falls from 16gm-3 to 5gm-3.

  • Since NFI uses fine fibres most of the activity is at the fibre

surface.

  • Combine with high internal surface area means efficient

capture and release of water since very little energy is taken to transport moisture from and to the fibre surface.

slide-44
SLIDE 44

Breathability

Air Temp Falls RH increases Fibre binds water vapour RH falls Condensation risk reduced

No liquid water involved

As RH increases natural fibre pulls RH away from dew point. This always happens below the fibre saturation point of the fibre

Variation in fibre diameter and length help absorb different frequencies. Absorption coefficient – fraction of sound energy absorbed by a material at a given frequency. 1 = 100%, 0 = 0%

slide-46
SLIDE 46

Heat

  • Thermal conductivity of natural fibre

insulation varies between 0.035 WmK-1 to 0.044 WmK-1.

  • Value varies little with moisture content up to

the fibre saturation point (approx 30% mc).

  • Makes insulation vary stable across a range
  • f humidities.
slide-47
SLIDE 47

Sustainability

  • Local.
  • Safe to handle.
  • Rapidly renewable.
  • Impacts are beneficial and vary depending on

product and source but all natural fibres sequester atmospheric carbon for their lifetime.

slide-48
SLIDE 48

Finally

  • Consider all your priorities.
  • Natural fibres are often the best answer.

Quick Guide; Design a) 75%+ of building failure is due to moisture. b) You cannot stop moisture getting into the building fabric.

  • Therefore you need robust measures aimed at

preventing it getting in, while accepting b).

  • And systems that regulate moisture at safe

levels within the fabric for when it gets in.

Quick Guide; Materials

  • Employ materials that are vapour open, and

can buffer and wick moisture.
