Largely manufactured from recycled glass (e.g. windscreens) and mineral base materials such as sand and without the use of binding agents. The ingredients are melted into molten glass, which is cooled and crushed into a fine powder. The powdered glass is poured into molds and heated (below the melting point) in a "sintering" process that causes the particles to adhere to one another. Next, a small amount of finely ground carbon-black is added and the material is heated in a "cellulation" process. Here, the carbon reacts with oxygen, creating carbon dioxide, which creates the insulating bubbles in the (material). CO2 accounts for more than 99% of the gas in the cellular spaces.
Cellulose insulation is a material made from recycled newspaper. The paper is shredded and inorganic salts, such as boric acid, are added for resistance to fire, mould, insects and vermin. The insulation is installed either blown or damp-sprayed depending on application.
Wood fibre
The success of wood fibre insulation derives from an attractive environmental profile combined with a whole bag of functions including rigid insulation, sheathing and sarking for timber frames, roofs and flooring as well as flexible insulation for studs and rafters.
Wood of course is renewable, it sequesters carbon during its growth and product production is relatively free from pollution. The insulation value of wood fibre boards is not as dimensionally efficient as some of the orthodox petro-chemical materials - but it's no slouch either - typically coming in with a 'k value' range of between 0.038-0.043 W/mK depending on format.
Hemp
Hemp fibres are produced from hemp straw of the hemp plant. Most hemp is imported, but an increasing amount of home-grown crop is becoming available. Hemp grows up to a height of nearly 4 metres within a period of 100-120 days. Because the plants shade the soil, no chemical protection or toxic additives are required for hemp cultivation. The product is composed of, usually, 85% hemp fibre with the ballance made up of polyester binding and 3-5% soda added for fire proofing.
Straw
Straw is an agricultural by-product, the dry stalks of cereal plants, after the grain and chaff have been removed. Straw makes up about half of the yield of cereal crops such asbarley, oats, rice, rye and wheat.
Knauf is part of the Knauf Group, one of the largest independent building and insulating materials groups in the world, employing around 35,000 staff in over 86 countries and more than 250 production facilities. KNAUF® is the largest producer of plasterboard in the UK. In fact, the company invested more than £100 million in the most advanced manufacturing technology to make one of the largest suppliers of gypsum-based building materials in the UK. The company was founded by Brothers Karl and Alfons Knauf in 1932 after securing the right to mine gypsum deposits in the Schengen community in Germany.
A year later, Knauf built its first gypsum factory in Perl, southwest Germany. The UK business began in 1988 when the Knauf Group built a plasterboard factory in Sittingbourne, Kent. Two years later, the company opened a second plasterboard plant in North East Lincolnshire. Immingham was extended in 2006, massively increasing its capacity. The latest energy management technology was incorporated, the whole plant insulated and two huge heat exchangers added, saving 10% of the plant's energy requirements. Both factories operate 365 days a year and have the capability to produce the complete range of Knauf Plasterboards, Thermal Laminates and foil backed Plasterboards. The production system, which was engineered and designed using the most modern manufacturing technologies, enables the production of a wide range of superior quality standard and high performance plasterboards and insulating laminates.

Today the Knauf Group is led by former Bosch Rexroth President Manfred Grundke in the position of Managing Partner, alongside Alexander Knauf who is also Managing Partner. From its beginnings in gypsum processing along the Saar and Main rivers, Knauf has expanded and diversified to become a corporation with worldwide activities, delivering products and services in the following fields:
Building materials and systems based on gypsum and gypsum-related products
Thermal insulating and sound insulation materials
Limestone and lime products
Chalk and cement related products
Plant engineering
KNAUF® PRODUCTS OVERVIEW
Knauf offer a variety types of products, all designed to help you insulate your home:
Knauf insulation is also a great choice when it comes to thermal protection, sound absorption, fire resistance and moisture control in all applications you can think of:
ECOSE® Technology is Knauf unique bio-based binder which is used in the manufacture of all Knauf Glass Mineral Wool products and the majority of Rock Mineral Wool products.
The Knauf Mineral Wool made with ECOSE® Technology contains no added formaldehyde or phenol. This means insulation generates very low levels of dust, increasing the comfort of those handling it. ECOSE® Technology makes insulation soft to touch and easy to handle.
Moreover, it is made from natural raw materials that are rapidly renewable and is 70% less energy intensive to manufacture than traditional binders, so it is kinder to the environment too.
Products manufactured using ECOSE® Technology have a natural brown colour so you can see, as well as feel the difference.
