INSULATION FOR THE FUTURE Before the backdrop of climate and environmental protection aspects as well as exploding energy prices, thermal protection of buildings has become indispensable. Excellent thermal insulation of roofs, exterior walls, floors and basements is the cornerstone of low energy consumption. When it comes to new construction and to the renovation of existing buildings, Neopor® offers ideal insulation solutions for almost all components.

INTERIOR INSULATION
The foamed Neopor® insulation panels are located and protected between the exterior concrete wall and the interior non-flammable gypsum board as the finishing materials, and the Neopor is attached to the concrete wall with cement adhesive. Foamed Neopor® insulation panels are very easy to produce, transport and handle by every player in the value chain in Korea. Composite panels made of Neopor®, which can be installed all the way up to the ceiling, are particularly convenient. When professionally sealed, they form an ideal substrate for painting and wallpapering work as well as for laying tiles. An assessment of the physical structure of the outer wall is recommended. Window soffits, floors and interior wall joints should likewise be insulated in order to reduce the formation of thermal bridges. The additional elasticity brought about up by Neopor® can also improve sound insulation.
Interior wall insulation is the predominant form of thermal insulation in Korea. It offers a clear-cut advantage for spaces that have to be heated up or cooled down quickly or only for brief periods of time. In addition, it makes restoration and renovation work easier (the facade can be retained) and it simplifies the work process when homeowners choose to remove walls or to move them to a different location.

EXTERIOR INSULATION (EFIS)
INSULATING CONCRETE FORMS (ICF)
Exterior wall insulation is used in smaller structures such as single-family homes, schools and commercial buildings. In the winter, the cold is kept out, while in the summer, the heat cannot get in. This type of insulation protects the load-bearing inner shell or the existing exterior wall against thermal loads and it also provides protection against the weather.
Formwork blocks are hollow foam forms installed at the construction site and filled with concrete. Formwork elements and molded parts made of Neopor® are suitable for all kinds of components that require thermal insulation and ease of processing. They are employed as wall and floor elements for single-family houses as well as multi-storey buildings.

Thanks to the outstanding thermal insulating properties of panels made of Neopor®, better insulation coefficients can be achieved with thinner insulation materials. The exterior insulation made of Neopor® is installed on the outside of the wall and coated with a reinforced special stucco. Mineral-based as well as dispersionbonded stucco systems can be used.
Formwork elements made of Neopor® make it possible to build and insulate exterior walls at the same time. The elements are available in various wall thicknesses and designs. Thanks to their good thermal-insulating properties, double-sided ICFs (insulating concrete forms) made of Neopor® are well-suited for the construction of lowenergy and passive houses.

CAVITY INSULATION
INSULATION BEHIND CURTAIN WALLS
In new construction, double outer walls provide ideal possibilities from an architectural and physical standpoint. Panels made of Neopor® can be employed for frost-resistant back-ventilated masonry as well as purely for cavity insulation that is not back-ventilated.
Back-ventilated curtain walls consist of a substructure, insulating material, an air layer and facade covering. They are used for design reasons and also due to safety considerations of a technical nature. The exterior walls can be tailor-made to match the characteristics of a given building.

In double-wall masonry, the space between the outer frost-resistant masonry shell and the inner load-bearing structure is limited. Owing to the low thermal conductivity of insulating materials made of Neopor®, a relatively higher insulating effect can be achieved. Retrofitting a wall with cavity insulation can be done by blowing expanded beads made of Neopor® into the existing cavities.
Outer skin (Air layer) Cavity insulation made of Neopor®
The two-layer system of a back-ventilated curtain wall systematically separates the functions of weather protection and insulation, thus ensuring thermal insulation that is permanently dry and functional. The back-ventilation reliably eliminates any moisture stemming from the structure itself or from the utilization of the building. Thanks to its outstanding insulating capacity, Neopor® is the material of choice for use in this facade system.

Outer wall insulation, general wall information
GENERAL CONDITIONS FOR INSULATION INSTALLATION During installation at construction site, cut precisely in a straight line using a cutter. Work must be carried out with precision to ensure no gaps in convergence points and outer edges. In areas where thermal insulations come into contact with each other, seal the connecting area using tape. For double-layer thermal insulation, make sure the connecting areas intercross and tape the outer layer. For side walls, attach on the wall surface of the pertinent floor completely before moving on to the next process. When gaps appear, fill them with urethane foam.
CAVITY TREATMENT OF HOLLOW WALLS When installing Neopor® thermal insulation in the cavity of hollow walls, fix it in place via penetration with a connecting wire which is covered by the bricks, as is the case when giving air space during brick-laying.
INTERNAL WALLS The use of plasterboard bond provided by the plasterboard company is recommended when adhering thermal insulation to plasterboard. For stronger adhesion of Neopor® thermal insulation and plasterboard, apply primer to thermal insulation before the adhesion process.
GENERAL CONDITIONS FOR INSTALLING COMPOSITE THERMAL INSULATION SYSTEM In a composite thermal insulation system, a polypropylene surface layer or magnesium board is attached to Neopor® thermal insulation using a water-resistant adhesive for damage prevention. The system must provide insulation beyond that required for the applied area.
POLYPROPYLENE SURFACE LAYER An incombustible (grade 2) polypropylene board having a hollow space and measuring three mm in thickness. The exposed side should be coated to allow for easy wallpapering and maintenance and to prevent deformation. It must have a weight of over 800 g/m2.
MAGNESIUM BOARD An incombustible (grade 2) flat board made of a blend of magnesium, wood powder and pearlite measuring 3 mm in thickness that complies with KS F 2271. In accordance with KS L 5114 test methods, it should have an absorption rate of below 30 percent and a bending strength of over 14 N/mm2.
ADHESIVE Use an epoxy type adhesive to join Neopor® thermal insulation and surface board. All sides should be coated with the adhesive for areas within 50 mm of the surface board edge. The adhesive should be applied to more than 80 percent of the surface board.
regulation Korean regulators are increasingly focusing on high quality insulation materials and energy-saving when it comes to insulation-related construction law. Naturally, this trend can be observed on a global scale taking into account rising oil prices, global warming and limited resources of our eco-system.
Neopor®, the eco-efficient insulation solution by BASF, is clearly in line with these trends by means of its outstanding thermal performance, eco-friendliness and impact sound insulation properties. With Neopor®, you are prepared for the future!

THERMAL PROTECTION
THERMAL CONDUCTIVITY
The outstanding effect of insulating materials made of Neopor® gives engineers and processors decisive advantages in actual construction projects. In comparison to conventional EPS, Neopor® allows more streamlined structures while providing a better insulating effect. Infrared absorbers or infrared reflectors make it possible to greatly reduce thermal conductivity. For instance, the permeability of the material to radiant heat is more restricted than with commonly employed insulating panels and the insulation effect is up to 20 percent higher than with conventional EPS panels.
The figure (diagram) shows that insulating materials made of Neopor having a density, for example, of 30 kg/m³, attain a thermal conductivity of 0.029 W/(m·K). Conventional EPS having the same density exhibits a thermal conductivity of 0.032 W/(m·K).
SOUND PROTECTION
FIRE PROTECTION Neopor® is a polystyrene rigid foam rated in Material Class B1, i.e. fire-resistant, and is categorized as non-burning dripping.
Insulating materials made of Neopor® not only account for energy savings but also considerably improve the sound protection of buildings. Studies have shown that the sound-insulating properties of thermal insulation composite systems with Neopor® bring about an improvement of the sound-insulation coefficient of up to 4 dB, depending on the solid wall, the panel thickness and the type of stucco or plaster.
ECO-EFFICIENt building with neopor® The eco-efficiency analysis looks at products and processes from an economic and environmental standpoint in order to find which ones are the most efficient. In comparison to alternative products, Neopor® offers a greater benefit at lower costs and with less impact on the environment. The huge advantage of Neopor® stems from the fact that it uses as much as 50 percent less raw material, as a result of which costs can be lowered and resources can be saved, all of which, in turn, alleviates the environmental burden. The same insulation effect is achieved with an insulating material that is 15 to 20 percent thinner. This translates into eco-efficient insulation solutions for modern thermal protection.
