Not only does Black Mountain use up to 90% less embodied energy in comparison to many man-made insulation products, the wool fibres used in their products permanently absorb significant quantities of carbon dioxide during their growth cycle. Therefore natural fibre insulations are ‘carbon negative’ – locking up a substantially higher level of carbon than used during their manufacture.

Black Mountain Sheep Wool Insulation Rolls are also a popular choice for van and bus conversions and RV applications!  Sheep Wool handles moisture better than other insulation materials, and also handles road vibrations better.  Our Van Conversion Page summarizes some information for and from people doing van and bus conversions.

Advantages

• Controls condensation, wool absorbs and releases moisture yet doesn’t lose it’s thermal performance, wool can in fact absorb up to 40 percent of its own weight and remain dry, to the touch.
• Wool actually heats up when absorbing moisture by up to 45 degrees F, this increases the dew point temperature reducing the risk of condensation.
• Wool absorbs harmful gasses, e.g. formaldehyde, and then locks them up permanently. Man made insulation emits gases.
• A better insulator compared to glass fiber insulation, requiring 10 percent less thickness to achieve the same insulating factor.
• Glass fiber thermal performance deteriorates dramatically when any moisture is present, wool’s performance is not affected.
• Wool will last for the life of the building due to the resilience of wool, glass fiber may compact and require topping up after 10 years.
• Wool is truly sustainable, a yearly clip of wool is available as a by-product of the livestock farming. Mineral wool depletes the world’s resources.
• Wool is a “Carbon sink”, it actually locks up CO2, man-made pollutes CO2 during its manufacture.
• Very low energy required in its manufacture, requiring 85 percent less energy compared to man- made products.
• Biodegradable at the end of its life.
• Safe to handle, no skin or respiratory problems typical of mineral wool.
• Wool is naturally fire retardant
• Lastly sheep wool insulation is a product of choice from the consumers perspective, who continue to express their concerns with mineral wool insulation.

Wall, ceiling, and floor insulation is often used as a component of soundproofing.  Any insulation product will improve your soundproofing compared to a hollow cavity.

However, if you are attempting to address a serious sound control problem that is impacting health or relationships with family or neighbors, you will want to educate yourself on the intricacies of sound control problems and the corresponding solutions.  We recommend you start by visiting our friends at the Soundproofing Company as they are the industry experts.

If installing within rafters right below a roof, make sure you have ventilation from soffit vents up through a ridge vent and/or gable vents, or a roof-mount fan, or else use a vapor barrier.
