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.
Finnfoam was established in 1982. Over the course of its nearly forty-year-long history, Finnfoam has become one of the leading manufacturers of plastic-based thermal insulation solutions. Company offers customers patented products and solutions whose insulation capacity, reliability and ease of installation are at a level of their own. Innovative inventions have led to several patents and successful products, which enabled the company to grow operations internationally. Finnfoam continues to increase production capacity and today produce insulation products in Sweden, Estonia, Lithuania, and Spain in addition to Finland. For almost 40 years, Finnfoam has been relied on for various demanding applications ranging from train tracks to public buildings, shopping centres and industrial facilities. Finnfoam has implemented a certified and audited ISO 9001 Environmental Management System. Company also comply with specific product group standards (EN13164 for XPS production, EN13165 of PIR production, and EN13163 for EPS production), while still carrying out their own quality control activities with a significantly higher frequency than that required by the standards.
FINNFOAM® PRODUCT RANGE
Finnfoam thermal insulation boards are the main product of the Finnfoam group. The boards are made from polystyrene using an extrusion method that allows for a completely consistent and closed cell structure. Similar materials are internationally referred to with the general term XPS. In addition to XPS thermal insulation, Finnfoam also offer various other construction insulation materials.
FF-XPS
XPS Finnfoam is a thermal insulation product made from extruded polystyrene, which retains its insulating capacity in even the most demanding conditions. The panels special feature is its completely closed and consistent cell structure, which ensures a high insulating capacity and impermeability. It is suitable for use as frost insulation and for insulating floors, ceilings, and walls, as well as various in supplementary thermal insulation applicatications.
FF-PIR
At the end of 2014, Finnfoam Oy introduced the new FF-PIR thermal insulation products made from polyurethane (PU). As a result of continuous product development, the FF-PIR insulation product family has once again been expanded, and since the summer of 2017 the thermal conductivity of all FF-PIR insulation products has been 0.022 W/mK. As the FF-PIR brand name denotes, Finnfoam Oy only uses PIR insulation materials whose fire endurance is significantly better than that of PUR insulation materials. The fire rating of the insulating foam component of FF-PIR insulation is D-s2, d0. The CE marked FF-PIR is also a mould-proof and safe material in terms of moisture performance.
FF-EPS
FF- EPS is a new type of insulation product intended for insulating floors, walls and ceilings. It is significantly more cost effective than the traditional EPS thermal insulation. The new technology enables an improved thermal insulation capacity in relation to density, which means that it provides better insulation with lighter panels. The FF-EPS panels are made from polystyrene, but using a completely different production method. The range consists of FF-EPS 100 kPa (thickness 85–200 mm) and FF-EPS 60 kPa (thickness 100–400 mm), which was designed specifically for insulating walls and ceilings.
In terms of properties, the FF-EPS 60 wall and ceiling insulation is in a category of its own. It has very high water vapour resistance, 25–40% better bending and shearing strength than similar EPS insulation products, as well as excellent dimensional stability and insulation capacity, which is λD 0.031 W/(mK). In addition, the panel size of 1,200 x 600 mm facilitates installation and allows for two-way fitting, while the locking tongue and groove profile ensures leak-proof insulation without thermal bridging. One side of the panel has two-way grooves, which significantly improves adhesion where necessary, for example on concrete. The FF-EPS is also available with larger two-way fluting, which function as ventilation ducts.
FF-SIGNAL
The FF-SIGNAL signal amplifier is an innovative passive element that relays signals while also isolating against cold and moisture. The product is developed and made in Finland by partners Finnfoam Oy and StealthCase Oy. A mobile phone signal passing through wall structures is 30-100 times stronger when relayed through the amplifier, which enables fast and reliable connections indoors even in challenging targets.
The signal amplifier is installed inside the structures, e.g., in between window frames or under the plastering of a concrete wall. FF-SIGNAL can withstand UV radiation during construction, but it needs to be protected from UV radiation in long-term storage. Before installation, the FF-SIGNAL amplifier is to be stored at the construction site protected from weather. FF-SIGNAL requires no maintenance and it will work inside the wall of a building for decades, which makes the passive FF-SIGNAL an extremely competitive solution for reception problems over its lifecycle when compared to retrofit solutions.
TULPPA®
Tulppa® is a new type of waterproofing panel designed for wet rooms. The core of the panel is made from a closed-cell, waterproof and mould-proof. It is horizontally installed and functions as both a construction board and waterproofing material. Due to the patented installation system, the Tulppa® panels with a rabbet profile are quick and easy to install. A professional fitter is easily able to complete 10–15 m2 of waterproof wall surface ready for tiling per hour. Tulppa® is easy to work with and light to handle. The panels’ innovative and patented horizontal installation method makes installation easier and the rabbet profile ensures waterproof seams. The system saves a significant amount of time, as it eliminates the need to apply water insulation and to wait for the insulation to dry. The Tulppa® wet room panels are ready for tiling in less than a day.
