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.
Acoustic plasterboard also called soundproofing board is a higher density plasterboard made in a slightly different way to provide greater acoustic performance than regular wallboard. The core of such a gypsum board has a clearly crystalline structure. In fact, acoustic boards are’t manufactured to be thicker but simply denser. This improvement comes from the higher density gypsum based core. Sound board is also blue in colour. This is because of the properties infused into the gypsum during the manufacturing process and the colour of the paper lines used to differentiate it from other types of plasterboard which have different properties. Blue plasterboard is approximately 30% heavier than standard wallboard, allowing for a noise reduction of between 30-50 decibels(dB). This soundshield board has a higher mass than standard plasterboard and it is this mass that assists in the reduction of airborne sound transferring from room to room by blocking sound energy. This gives enhanced sound insulation to walls and ceilings. Noise reducing plasterboard can easily control noise disturbance caused by television, loud home sound systems or just general everyday life. It can be used on a party wall (shared wall in terraced house) to help soundproof the wall from noisy neighbours. Since it handles in the same way as regular plasterboard, it can be easily decorated with plaster finish, paints, wallpapers or any colour you like. Acoustic plasterboard dB reduction is incredible as it reduces noise by up to 50dB. Even though this plasterboard costs more than standard wallboard, it is worth buying if you are concerned about noise levels from neighbours or would just like the peace of mind that comes from knowing you will be able to sleep quietly. The best acoustic plasterboard should weigh at least 29kg. For the best results, there should be more than one layer in the plasterboard. Some of the most popular manufacturers such as Kanuf or British Gypsum make heavier sheets than others due to higher density and enhanced gypsum. For instance, a busy restaurant would have a noise level of about 70dB. If you added an extra layer of plasterboard and maybe soundproof foam between it, then almost no noise should get through. A standard stud wall built properly and consisting of 2 sheets of acoustic boards with an air cavity from 5 to 6 inches thick, is good enough to make the wall fully soundproofed.
ACOUSTIC PLASTERBOARD SIZES ǀ MANUFACTURERS
Soundproof plasterboard is exactly the same thickness as normal plasterboard, despite the extra density, so the blue boards can be mixed and matched interchangeably, depending on what your requirements are for the area that you are working on. Acoustic plasterboard can be found as thin as 12.5mm. Either 12.5mm or 15mm is supplied with a tapered or square edge depending on the manufacturer. Our range of acoustic plasterboard features products from industry-leading manufacturers such as British Gypsum (Gyproc Habito®), Knauf (Soundshield Plus), Fermacell (High Performance Building Board) or Siniat (Gtec dB board).
Acoustic plasterboard comes in exactly the same thicknesses as normal plasterboard so can be used alongside it without a problem. Available sizes are:
12.5mm x 1200mm x 1200mm (1.44 sqm) HALF SIZE 4’x4’
12.5mm x 2400mm x 1200mm (2.88 sqm) FULL SIZE 8’x4’
12.5mm x 3000mm x 1200mm (3.60 sqm) LONG SIZE 10’x4’
ACOUSTIC PLASTERBOARD APPLICATION
Sound absorbing plasterboard is a very popular option in places where there are many bedrooms such as hotels, hostels and halls of residence for students, as the noises are dampened through ceiling and this allows everyone to get more and better sleep than they otherwise might without the acoustic plasterboard being in place. In older properties, it is ideal as a ceiling between flats or as a wall lining for party walls. For any type of project, it is used to control excessive noise from rooms such as home cinemas, music rooms or music studios. This makes it a very popular building material for lodges and hospitals where many people are sleeping and need peace in order to do so. It can make a real difference to the quality of life in houses of multiple occupation, student accommodation where there is likely to be the sound transfer of a lot of noise, such as snoring or noisy neighbours. Soundproof tapered edge plasterboard can also be used for ceilings in order to reduce noise from above. This can be handy when in flats with upstairs neighbours who may be quite heavy-footed or who may not have much floor insulation in their rooms, leading to every noise becoming an aggravation. Acoustic plasterboard can be installed in exactly the same way as normal plasterboard, by using adhesives or screws. It can also be applied directly using Plasterboard Adhesive.
