How can we reduce carbon dioxide emissions while dealing with an increasing energy production to meet the growing demand? Achieving sustainable and energy-efficient buildings can be part of the answer.
Insulating a normal building can help avoid most of the energy losses. Among the most common insulating materials, polyurethanes stand out as the one of the most efficient solutions. The secret is to create passive buildings whose consumption is minimal. A concept born in Northern Europe for energy-saving construction – the passive house – is becoming a common practice also in other countries as France.
To achieve this, one of the determining factors is the insulation level. Polyurethane systems are the most outstanding in this field as they have the lowest coefficient of thermal conductivity. With the same thickness, polyurethane has a much higher performance than other insulation materials. In addition to its good thermal behavior, it also provides a sealing effect thanks to its continuity, avoiding thus cracks that could lead to thermal bridges.
Energy efficiency thanks to better insulation is an important step to reduce greenhouse gas emissions and help the world to decouple economic and social development from energy consumption.
