Thanks to being slightly denser than Comfort rolls, the SheepWool Optimal Roll offers both vertical and horizontal application, able to hold their shape and thickness throughout their lives. This gives you a variety of applications in which to use these rolls, including sloping ceilings, ceilings, walls and floors.

Made from 100% natural sheep wool, these insulation rolls also have fire safety advantages such as being non-combustible thanks to their high moisture content and will self-extinguish on ignition. You can install the insulation on existing glass wool and mineral wool as it is entirely breathable, helping to eliminate any harmful fibres found in mineral and glass wool.

Features & Benefits: Optimal SheepWool Loft Insulation 100pc Natural 75mm x 570mm - 6.84m2 Pack

  • No special PPE equipment or safety gear needed to handle
  • Sustainable, renewable and safe
  • 100% Sheep Wool non-combustible and self-extinguishing

SheepWool's Optimal roll also comes with patented coating Ionic Protect, a biocide-free coating that guards against moths as the fibres deter them from eating the insulation. This has been CUAP tested and is the only sheep wool insulation that benefits from this.

Optimal is a very competitively priced natural insulation range. Optimal leads the way in giving homeowners, builders and professionals the choice to use natural materials in their projects. Being produced in both 50mm and 75mm thick rolls, Optimal needs less layers layers to meet modern building regulations, saving time and even more money during installation.

Safe & healthy

  • Optimal is a safe material, not only to handle and install, but to have within your home. Wool fibres are completely safe to touch and work with, requiring no special handling or protective equipment. Optimal insulation rolls can be installed on top of existing glass or mineral wool, reducing the opportunity for their potentially hazardous particles to become airborne. Due to it's high moisture content, wool does not support combustion and will extinguish itself when the source of flame is removed. In the event of a fire, wool is a much safer material than man-made products as it does not release poisonous fumes.

Ionic protect

  • This product is unique in that it is the only product on the market to have Ionic Protect, a new biocide free wool protection system. Ecological, sustainable and durability proven! The procedure treats the wool fibre in a plasma-ionic way aiming to protect it against all the negative influences of the building environment. Ionic Protect sustains and protects sheepwool insulation, acting as a natural moth repellent and prevents the fibres from being eaten. The performance of Ionic Protect has been checked and confirmed by an independent laboratory (CUAP test).

Environmental benefits

  • Sheep Wool Insulation products have unrivalled environmental credentials, making it them the "greenest" choice of any insulation product on the market. Sheep's wool is a naturally occurring fibre, so it is a renewable and sustainable source of raw material. Wool has zero global warming potential and is carbon neutral, so choosing Optimal means your insulation will have no environmental impact. Sheep Wool Insulation also requires only a fraction of the energy to produce in comparison to other insulation materials. At the end of its useful life, Optimal can be reused as insulation, recycled into other wool products or buried where it will eventually biodegrade.
