    For Builders

    Why use sheep wool insulation?

    Isolena sheep's wool insulation is totally natural, environmentally friendly, and quick and easy to install. Here are some of the reasons why you should make sheep wool insulation a key part of your plans for a highly energy-efficient building.

    It adds value

    Sheep Wool Insulation makes sound economic sense because it immediately adds value to your development. Major international studies such as the Royal Institution of Chartered Surveyors' "Green Value" report show clear links between green buildings and their market value. Wool insulation and other eco-friendly products appeal to the growing numbers of home owners and buyers looking for green buildings with an excellent energy rating.

    It's safe

    Because the wool is natural, Sheep Wool Insulation is perfectly safe to handle. Unlike many other insulation products, you don't need special equipment or safety clothing to install it. That means a faster, hazard-free installation – and lower construction costs. Sheep Wool Insulation is quick and easy to work with, following the shape of the rafters, studs and joists for a tight fit. Sheep Wool Insulation is also ideal for refurbishments and restoration projects. You can roll it over the existing insulation instead of having to remove it. This is quicker and much safer than removing hazardous material, minimising health and safety risks on site.

    It's awardwinning

    Sheep Wool Insulation is certified as the highest performing fibrous insulation, maximising energy efficiency. We continuously monitor product quality to ensure these award-winning standards are maintained. Full testing and certification is carried out on all our products to ensure compliance with building regulations and to give you the confidence to make the best choice.

    We deliver

    We can also arrange delivery, using either our own vehicles or leading courier companies. Delivery charges are additional, but we always look for the most cost-effective delivery method. We also supply any other accessories you may need, such as cutting tools, membranes and tapes. See our online shop for more details.

    It's flexible

    Sheep Wool Insulation rolls come in a wide range of lengths and depths, and can be layered to achieve requirements. Whether it's a new development or a refurbishment, you can fit Sheep Wool Insulation anywhere – from external or internal walls, under timber or concrete floors to the attic/loft or between the rafters.

    For Architects & Specifiers

    Why use sheep wool insulation?

    Hundreds of architects and other professionals are now specifying natural materials in their building projects, and you cannot get more natural than Isolena sheep's wool insulation. For sustainable architecture, it is the best insulation product on the market.  Think of it as nature's thermostat: it keeps a building up to 4C warmer in cool weather and up to 7C cooler in warm weather.

    For creative projects

    Sheep Wool Insulation is ideal to use in your more creative projects, particularly where your clients want to:

    • Use natural products for a green build
    • Gain the longer-term cost benefits of energy efficient materials
    • Have a higher Building Energy Rating
    • Add market value to their property

    Major international studies such as the "Green Value" report by the Royal Institution of Chartered Surveyors show clear links between green buildings and their market value.

    Eco-friendly materials

    Sheep Wool Insulation ticks all the right boxes in terms of building materials that have low embodied energy and are:

    • CFC and HCFC free
    • Non-toxic
    • From sustainable sources
    • Sourced locally

    Wool and moisture

    Wool fibres are hygroscopic, absorbing and releasing moisture without reducing thermal performance. The fibres are breathable, with a moisture weight content of up to 35%, depending on the relative humidity of the surroundings. While absorbing this moisture, the wool releases energy in the form of heat, raising the temperature of surrounding areas. In warmer weather, the process is reversed – as the wool releases this moisture, it creates a cooling effect.

    Award-winning

    Sheep Wool Insulation is certified as the highest performing fibrous insulation, maximising energy efficiency. Full testing and certification is carried out on all our products to ensure compliance with building regulations and to give you the confidence to make the best choice.

    A flexible product

    Sheep Wool Insulation is a flexible product – literally. It is quick and easy to work with, following the shape of the rafters, studs and joists for a tight fit. You can fit Sheep Wool Insulation anywhere – from external or internal walls, under timber or concrete floors to the attic/loft or between the rafters. The rolls come in a wide variety of lengths and depths, and can be supplied to tailored measurements on request. Sheep Wool Insulation is also ideal for refurbishments and restoration projects. Your team can roll it over the existing insulation instead of having to remove hazardous material.
