Sheep Wool Insulation Premium is a range of grey coloured sheep's wool insulation rolls offering high thermal and acoustic performance. Premium rolls are suitable for a wide use of applications, including internal & external walls, ceiling & rafter level applications and floors. Premium insulation rolls are available in a variety of convenient dimensions.The premium rolls are cut jagged which means the rolls can be very easily ripped diagonally as a result, making for easier installing which means there is no need for cutting, they are also easier to use and cutting to length is possible without any tools. Apply the insulation roll from bottom upwards and fix the sheep wool insulation with a tacker or staple gun if necessary. Please note this product is 100% pure, natural sheeps wool insulation. High Performance Premium is a highly effective insulation roll with a superior thermal performance over almost all natural and man-made fibre insulation products. Premium is made of pure new wool fibres, which hold their shape and thickness right throughout their lifetime. Being produced from 100% pure wool fibres, Premium is a fully breathable material that will maintain it's thermal efficiency even in the harshest climates. The high density of wool fibres in Premium make it an excellent acoustic as well as thermal insulation. PropertiesLength: 4m. Width: 570mm. Thickness: 150mm. Roll size: 1.71m2. Pack quantity : 2x rolls. Pack coverage: 3.42m2. Natural insulation: 100% pure sheeps wool. Thermal conductivity: 0.0359 W/mK. Raw density: 20kg/m3. Safe & healthy Premium 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. Premium 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 protectThis 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 labaratory (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 Premium 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, Premium can be reused as insulation, recycled into other wool products or buried where it will eventually biodegrade. Value Premium is initially a higher cost product than most common insulation types. However, Premiums performance advantage and lifespan, means that over it's lifetime, it will perform considerably better than it's competitors. At Premiums density, Sheep Wool Insulation continues to supply the lowest priced pure wool insulation range in the world, Premium offers a natural insulation product range that can be used right throughout a building, making it an effective solution for a range of applications. For convenience, Premium is produced in 50mm, 75mm and 100mm allowing any depth to the nearest 25mm to be acheieved. Due to it's higher performance, Premium will ofter require less material thickness than it's competitors to acheive a similar thermal performance and can be used in situations where man-made fibre products would not meet building regulations.
