All known heat insulation systems are loose materials that can take in water. In this regard, insulating and aesthetic applications require different products and additional workload. Polyurethane, on the other hand, incorporates both high insulation and a decorative finish in a single process. Its visual properties are very high, flexible and diverse. Polyurethane precast facade coatings and decorative materials stop heat and water at the first step.
It is an irreplaceable facade material with both indoor and outdoor applications in the construction sector, with such properties as: outstanding physical and chemical endurance,
Infinite model and solution choices,
High endurance values,
High production and rapid assembly,
Low transportation costs,
Energy efficiency and savings,
Minimum building load.
Polyurethane is the insulation material with the lowest lambda (λ) value, being the thermal conductivity coefficient. The value for insulated decorative facade coatings determined by accredited agencies, even for 160 density (160kg/m³), is λ = 0.0242 W/mK. Decorative facade coatings and ornamental panels with high lambda and insulation values can be produced in various thicknesses for different climates.
Polyurethanes provide sound insulation up to 50 decibels thanks to their closed cell structure. Furthermore, polyurethane panels can be produced in sound absorbing forms, bringing these values much higher.
Polyurethanes do not absorb water thanks to its closed cell structure. Thus, insulation values do not decrease.
The closed cell structure of polyurethane facade materials prevent water and moisture absorption, and so they resist the production or holding of bacteria, and do not decay or smell; they are modern, hygienic and technological products.
Harmful gasses (HFC) are forbidden in our country, just like in the European countries. Production now features new, environmentally friendly generation agents. The material does not have any risks after it has been produced, and so polyurethane is environmentally friendly in this respect.
Polyurethane has quite a long lifespan. While there may be a 10% fall-off in insulation values over the first 15 years, and 15% over 30 years, due to the opening of closed cells, the lifespan of the insulation is parallel to that of the building.
Polyurethane products accept all kinds of paint, whether water- or solvent-based. It contains no chemicals like cement or lime, and so facade paints last longer and maintain their color since there are no chemical diffusions to the outside due to chemical reaction. In parallel with the quality of your facade painting, it maintains vibrancy and provides more durability against outside conditions.
Surface rigidity can be produced in the most used 180kg/m³ density, with a Shore value of D 25-30. Weight and density are directly proportional to rigidity. Special productions can reach up to 1200kg/m³ density and Shore D 80-90 surface rigidity.
Polyurethane has high dimensional stability, with no expansion experienced within the -30 to +70°C temperature range. Polyurethane expands by around 0.5% at +70˚C and this can reach 1% at temperatures over +70˚C. In applications in which temperature values outside this range are expected, special joint gap applications may be necessary.
The raw material of polyurethane is cast as a liquid and takes the shape of the mold. In this regard, the model and pattern alternatives are as wide as your imagination.
Outdoor usage. The application of polyurethane materials is quick and easy. The advantages it brings in terms of speed and efficiency cannot be compared to other known systems, and the production and application process of conventional coating systems. In small-scale or low buildings, adhesion is through polyurethane mastic. Mechanical assembly may be required for taller buildings. It ensures significant cost savings in terms of work delivery time, labor, insurance and scaffolding rent.
It is very light. It ensures high savings in transportation costs. It reduces application times drastically. Today, the most important expectation of a building application is durability, and polyurethane is one of a kind in this sense.
Polyurethanes are produced in B2 and B1 degrees of incombustibility.
