Polystyrene is a synthetic aromatic polymer made from the monomer styrene. Polystyrene can be solid or foamed. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year.
Polystyrene foams are produced using blowing agents that form bubbles and expand the foam. In expanded polystyrene, these are usually hydrocarbons such as pentane
Extruded polystyrene (XPS)
Extruded polystyrene foam (XPS) consists of closed cells, offers improved surface roughness and higher stiffness and reduced thermal conductivity. It is slightly denser and therefore slightly stronger than EPS.
Water vapour diffusion resistance (μ) of XPS is very low - making it suitable for application in wetter environments.
Phenolic foam
Phenolic foam insulation is made from a resole resin in the presence of an acid catalyst, blowing agents (such as pentane) and surfactants.
Polyisocyanurate/ Polyurethane foam (PIR/PUR)
Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. Polyurethane can be made in a variety of densities and hardnesses by varying the isocyanate, polyol or additives.
Polyisocyanurate, also referred to as PIR, is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. Its chemistry is similar to polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol. Catalysts and additives used in PIR formulations also differ from those used in PUR.
Glass mineral wool
Made from molten glass, usually with 20% to 30% recycled industrial waste and post-consumer content. The material is formed from fibres of glass arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. The density of the material can be varied through pressure and binder content.
Rock mineral wool
Rock (Stone) mineral wool is a furnace product of molten rock at a temperature of about 1600 °C, through which a stream of air or steam is blown. More advanced production techniques are based on spinning molten rock in high-speed spinning heads somewhat like the process used to produce candy floss. The final product is a mass of fine, intertwined fibres with a typical diameter of 2 to 6 micrometers. Mineral wool may contain a binder, often a Ter-polymer, and an oil to reduce dusting
Cellular glass
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.
Wool
Wool insulation is made from sheep wool fibres that are either mechanically held together or bonded using between 5% and 15% recycled polyester adhesive to form insulating batts and rolls. Sheep are no longer farmed primarily for their wool; however, they need to be clipped annually to protect the health of the animal. The wool used to manufacture insulation is the wool discarded as waste by other industries due to its colour or grade
Cellulose
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.
CELOTEX® began life in London in 1925 but has now been based in Suffolk for just over half of its 87-year history. The company grew throughout the 20th century and expanded its product line to include a variety of construction materials such as roofing shingles and siding. Celotex® continues to operate in the present, producing various building sheathing and insulating products, having passed through various reorganizations and changes. Celotex® has retained a “family business” culture, with many employees staying for many years, and sometimes with several generations of the same family working for the company.
The success of the UK sales operation, originally based at offices in The Strand, led to the creation of a factory at Stonebridge Park, in north-west London, where work started in 1937. In the 1970s, however, the Celotex® Corporation introduced a new type of ceiling tile made from the polymer isocyanurate which led eventually to development of the current product range, with production of rigid polyisocyanurate (PIR) starting at Hadleigh in 1980.
Today,Celotex® is the UK market leader in high-performance PIR insulation solutions.
Celotex® An Inventor Of 12mm PIR Insulation Board
Although the excellent thermal insulation properties of PIR were recognised, it remained something of a niche product for many years. PIR is one of the fastest-growing insulation sectors in the UK. Although the Hadleigh plant is now the largest PIR facility in the UK, Celotex® is by no means the only player in the game.
Celotex® aims to enhance its offer through innovation, service and support. In fact, Celotex invented the thinnest PIR insulation board with an incredibly low thickness of 12mm. Thinner PIR insulation products are expected to grow as they are useful for “retrofitting” in existing buildings where space is at a premium. The 12mm PIR board soon became the company's flagship product.
Today, Celotex® PIR boards are recognized to be one of the thinnest insulation boards on the market, whilst still achieving premium levels of energy efficiency and U values. The company also offers the greatest range of PIR products, including both the thinnest and the thickest boards on the market. Thicker boards help meet the higher levels of insulation now required.
Innovation has also included the introduction of PIR insulation boards laminated with 12.5mm plasterboard, which speeds the construction process on-site. Celotex PL4000 insulated plasterboards made from PIR insulation core bonded to 12.5mm plasterboard are a beautiful example of the efforts the company has made to reduce costs of installation.
3 Celotex Groups of General Purpose PIR Insulation Boards
Celotex® provides a range of general-purpose insulation boards that can be used in masonry walls, pitched roofs, flat roofs and more.
PIR Insulation boards are versatile and available in a wide range of thicknesses from 12mm up to 200mm.
Celotex® grouped the boards into 3 product ranges, starting from 12mm up to 45mm, from 50mm up to 100mm and from 110mm up to 200mm thick. Group will strongly depend on the application type.
The Celotex® TB4000 range is a high performance PIR board with thicknesses ranging from 12mm to 40mm. The thin characteristics of TB4000 mean that the TB4000 range is particularly suited to combatting localised heat losses and thermal bridging. The TB4000 Range comes in 7 thicknesses: 12mm, 20mm, 25mm, 30mm, 35mm, 40mm and 45mm.
Celotex® GA4000 insulation boards are very similar to TB4000 insulation boards, in that they are general purpose PIR boards that can be used in a number of different applications. However, TB4000 insulation boards are much thinner than the GA4000 range. The GA4000 Range comes in 7 thicknesses: 50mm, 60mm, 65mm, 70mm, 75mm, 80mm, 90mm and 100mm.
XR4000 Range insulation boards have been developed to provide simple solutions for overcoming localised thermal bridges. Celotex® XR4000 is targeted at ‘cut-to-fit’ applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible.
XR4000 Range comes in 7 thicknesses: 110mm, 120mm, 130mm, 140mm, 150mm, 165mm and 200mm.
Celotex® PIR insulation has been independently assessed by BRE Global and has been accredited with an A+ rating when compared to the BRE Green Guide 2008. The results also show that Celotex offers a lower environmental impact than other typical PIR manufacturers.
