True Sustainability

Sheep Wool insulation is truly sustainable; each year over 50 million kilograms of wool are sheared in the UK alone. Black Mountain uses the ware dark coloured wool that is not required by other industries.

Man made insulation can only be disposed of into landfill; no recycling system is currently in place. Whereas sheep's wool insulation can be composted at the end of it's life; this not only generates soil enriching humus but also nitrogen fertilisers.

Easier to Install 

There are no health or safety risks when fitting sheep wool insulation, which means it is not just safer but faster too. Unlike rigid boards, black mountain fits easily between timber joists and provides a tight seal with a minimal effort because it is naturally flexible.

Sheep wool insulation is resilient - the wool fibre has a natural spring which ensures the insulation does not compact over time unlike other insulations. It is also very strong, yet can be torn by hand across direction to facilitate installation. 

Natural Condensation Control

Condensation is probably the biggest challenge facing architects and renovators today. Sheep wool can assist in solving this problem.

Sheep wool is very hygroscopic; it is unique in that it generates a significant heat as moisture is absorbed - in fact 1 kilogram of wool generates the same heat as an electric blanket emits for eight hours. The heat generated increases the dew point and thus reduces the risk of interstitial condensation; man made insulation cannot achieve this.

Ideal for Older properties  

Older properties don't fit the current standard rafter dimensions, requiring a lot of cutting and wastage. Black Mountain is unique in its ability to manufacture special widths to fit your project, thus reducing wastage and speeding installation. The installed cost is similar to the more expensive man-made boards.

Indoor Air Quality

Sheep wool insulation is unique in its ability to absorb and lock up toxic gases (sulphur dioxide, nitrogen dioxide and formaldehyde) - these gasses are given off by other building products and exhausts.
