Black Mountain Sheep Wool Insulation


Black Mountain Sheep Wool Insulation is a general purpose natural wool fiber product designed for use in loft, rafter, attic, wall, floor, basement, and crawl space applications in your home or building. Black Mountain Sheep Wool Insulation is also used in van and bus conversions where it is favored for its ability to handle and moderate moisture as well as its resiliency when subjected to vibrations. In fact, it is increasingly used within custom speaker enclosures where vibrations cause fiberglass and cotton to gradually disintegrate.

Black Mountain Sheep Wool Insulation meets and surpasses US building product standards for Thermal, Fire, Mold Resistance, and Structural performance. Natural wool insulation from Black Mountain USA is a healthy and green alternative.

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.

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.


In a well-spaced standard wall-framing there is usually enough friction for the insulation to stand within the wall cavity. If installing in a wall that is irregularly spaced or otherwise does not provide enough friction, or if installing between rafters or joists from below rather than from above, one may use insulation hangers, netting, or a staple gun to secure the insulation.

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.
