Types of insulation
Cellular glassLargely 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.
CelluloseCellulose 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 fibreThe 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.
HempHemp 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.
StrawStraw 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. - Blog
In the early 1970s, the Fermacell® facility located in Münchehof near Goslar, Germany, marked a significant milestone by introducing the very first gypsum fibreboard in the country. This pivotal moment laid the groundwork for the remarkable ascent of the Fermacell® brand. Their premium, exceptionally sturdy finishing board revolutionised the drywall construction sector, propelling Fermacell® to prominence and strength in the industry.
Powerpanel H2O is a cement-bonded and mineral-based construction board designed for wet and humid environments.

Powerpanel HD is a heavy-duty cement-bonded board known for its strength and durability. It is commonly used in demanding construction applications, such as for facades, load-bearing walls, and floors.
Fermacell produces gypsum fiberboards, which are a versatile building material. These fiberboards are often used for constructing interior walls and ceilings, offering good sound insulation and impact resistance. They are also environmentally friendly and contribute to sustainable building practices.
