Natural sheep's wool has a flexible profile, lasts longer and is more forgiving.

Condensation is one of the building industry's biggest challenges. Wool insulation is your safeguard against condensation.

Energy costs and concerns of global warming are rising fast.  The need to save energy and reduce our carbon footprint has never been greater. Natural sheep's wool insulation provides a high performance and truly sustainable solution to both consumption of energy and the effects of climate change. Wool is not only a better insulator but it actually generates heat when it absorbs moisture!

This natural wool insulation is designed to be used in new and existing buildings. It’s ideal for lofts, rafter, internal wall and inter-floor use.

The smarter choice - Wool has unique properties.

It absorbs and releases moisture with no impact on thermal performance. Wool absorbs and locks up toxic gases emitted by many building materials permanently. Natural sheep's wool offers improved thermal and acoustic ratings over most man-made materials. Wool fibre evolved over thousands of years to be the most technically advanced insulation material. Ideal for breathable walls. Sheep wool insulation is the smartest choice!

Why Sheep wool insulation?
Black Mountain believes sheep wool insulation is the best performing natural insulation available in the market place today.  Compared to man-made mineral fibre, sheep wool insulation has many advantages …

• Controls condensation - wool absorbs and releases moisture yet doesn’t lose it’s thermal performance; wool can in fact absorb up to 40% of its own weight and remain dry, to the touch.

• Wool actually heats up when absorbing moisture by up to 7ºC, 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 gasses.

• A better insulator compared to glass fibre insulation, requiring 10% less gauge to achieve the same insulating factor.

• Glass fibre 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 fibre may compact and require topping up after 10 years.

• Wool is truly sustainable, a yearly clip of wool is available as a byproduct 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% 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 wools.

• Black Mountain only uses virgin Welsh, Irish, Scottish and English wool, typically hill farmed e.g. Swaledale and Welsh Black Face, the product is truly sustainable and environmentally conscious and totally safe requiring no protective clothing to install.

• Supports economic deprived areas of Wales, Ireland, Scotland and England.

• Lastly sheep wool insulation is a product of choice from the consumers perspective, who continue to express their concerns with mineral wool insulation.
