Wool is a natural fibre from a fully renewable resource and consequently the life cycle of Thermafleece has minimal environmental impacts. And whilst it's gives a K-value of 0.039 W/m.K which compares favourably with that of other fibrous insulants, it's pleasant and safe to handle and offers a range of additional benefits that derive from it's nature, particularly from the way in which it interacts with moisture....

Thermafleece does far more than simply insulate your building. In addition to its inherent thermal efficiency, it also:

• improves air quality
• provides acoustic insulation
• regulates air temperature
• regulates air humidity
• controls condensation
• has minimal embodied energy
• is safe and healthy to install and to live with
• is durable
• is recyclable
  

IMPROVING AIR QUALITY
Few materials have wools ability to obsorb indoor air pollutants, including those chemicals and Volatile Organic Compounds [VOCs] that are given off by paint and construction timber, including formaldehyde. The abilities of Thermafleece in this regard have been proven by thorough academic research.

The Building Research Establishment [BRE] have shown that more than 200 pollutants are present in indoor air at 10 times the levels thatr they occur outdoors. Thermafleece naturally absorbs many of these by chemically bonding with them, usually permanently, rendering them harmless.

0ISE DAMPENING AND SOUND INSULATION
Thermafleece shows excellent acoustic absorbtion properties, particulary over the frequency range of human speech. Instaled within internal and stud partition walls, it therefore contributes greatly to comfort levels.

COOL IN SUMMER
When the outside temperature increases and begins to heat the wool, it releases moisture; that has a cooling effect on the fibre which reduces the flow of heat to the inside of the building. This can reduce peak temperature by up to 7 c when compared to buildings in which alternative forms of insulation are installed.

WARM IN WINTER
In the winter the absorption of moisture by wool insulation can increase peak temperature by up to 4 c when compared to buildings in which alternative forms of insulation are installed.

NATURALLY BREATHABLE
Thermafleece, being hygroscopic, can absorb and desorb water vapour without compromising its thermal efficiency. It is therefore ideal for use in roofs and timber framed walls designed to avoid a damaging build-up of moisture by allowing water vapour to migrate through the structure. In this type of construction, Thermafleece is the perfect partner for a vapour-permeable breather membrane used on the cold side of the thermal insulation to prevent the infiltration of cold air and wind driven rain and dirt. Heat loss by convection is also substantially reduced because the insulation is protected by the breather membrane preventing air movement across the surface.

CONDENSATION CONTROL
Wool generates heat when it absorbs moisture from the air. That energy is known as the heat of sorption and accounts for the warmth felt by wearers of woollen clothes in winter conditions. When the air is saturated with water vapour, wool absorbs some 40% of its dry weight in moisture, producing 960 kilojoules of heat energy for every kilogram of dry wool. This warmth is not noticeable inside the building but it acts to prevent condensation in construction cavities by maintaining the temperature above the dew-point in damp conditions.

ENERGY EFFICIENT
The cleaning, laying and thermal bonding processing during the manufacture of Thermafleece consumes minimal energy. Thermafleece uses only 14% of the embodied energy that is used to manufacture glass fibre insulation, therefore paying back its manufacturing energy cost seven times faster than glass fibre.

HEALTHY
Thermafleece is harmless and can be installed without gloves or protective clothing. It is not irritating to the skin, eyes or respiratory tract and causes no discomfort to site workers during installation. Any fibres which happen to reach the living space will present no hazard to health. The necessary insect proofing and fire resistance rating is achieved by the inclusion of naturally derived additives.

EXTREMELY DURABLE
The fibre adapts to the shape of rafters, joists and studs to provide a permanently tight fit. Properly installed, Thermafleece will retain its low density and thermal performance - with a life expectancy similar to that of the construction in which it is installed.

RECYCLABLE
At the end of its useful life, Thermafleece can be recycled for other environmentally friendly applications. Thermafleece contains no permethrin, pyrethroids, pesticides or formaldehydes.

Thermafleece is manufactured in batts of 1200 mm long and either 400 mm or 600 mm wide.

A range of three thicknesses are available - 50 mm, 75 mm and 100 mm enabling any overall insulation depth to be achieved by combining different thicknesses.

Thermafleece is sold in packs - 50 mm thick covers 20.16 square metres, 75 mm thick covers 12.96 square metres and 100 mm thickcovers 10.08 square metres.

Now also available in roll form - Thermafleece PB20

Warmcel 100 is a loose fill insulation and is provided in conveniently sized bags for spreading out over the loft floor area. By its nature, Warmcell 100 completely fills in between and around joists, wiring and pipework to ensure complete insulation. It isn't suitable for use where it is likely to be subject to excessive water ingress and so is better suited to roofs that are lined with felt or membrane.

DUE TO ITS BULKY NATURE THE DELIVERY OF INSULATION IS BEST ARRANGED UNIQUELY FOR EACH INDIVIDUAL ORDER.

Fire Performance
As the photograph shows, Warmcel is extremely resistant to fire. Its remarkable performance is achieved through the addition of simple inorganic salts, enabling it to comfortably meet the fire protection standards required for timber-frame construction and conventional lofts.  Warmcel is accredited by the Loss Prevention Certification Board (LPCB) for use in composite timber frame wall and ceiling systems in relation to fire resistance.

Thermal Performance
Warmcell 100 has an impressive thermal conductivity value (k) of only 0.035 W/mK at 100mm depth. The insulation helps to seal a loftspace by naturally filling spaces, preventing heat loss and eliminating gaps, cracks or other cold bridges. When laid between joists, it can be overlaid with boarding. Warmcell is higher density than many fibre insulations (it's actually four times the density of lightweight fibre products) and so it suffers less convected heat loss.

Environmental
Manufactured from 100% recycled waste newspaper, Warmcel has extremely low embodied energy, requiring far less energy to produce than other mainstream insulation materials. Warmcel has zero ODP (Ozone Depletion Potential). It does not contain any added formaldehyde and is free from CFCs, volatile organic compounds (VOCs) or other toxic substances. And by reducing heating demand, Warmcel also plays a major part in reducing household CO2 emissions.

Under the BRE's Environmental Assessment Method (BREEAM), Warmcel achieved Green Guide Ecopoint 'A' ratings in every application of the insulation in various wall and roof constructions. And in comparison with other insulation materials, the Ecopoints rating for Warmcel was so good it exceeded the current best 'A' rating value. When, eventually, Warmcel insulation is removed from a building, it can be recycled again or disposed of safely, without creating toxic waste or biodegradability problems.

Durability
Warmcel is resistant to biological and fungal attack, treated against insects and is unattractive to vermin. Warmcel is also harmless to other common building components such as copper pipes, electric cabling and metal nailplate fasteners.
