Polyurethane Systems for building and industry

To achieve maximum energy efficiency, which is a prerequisite for obtaining the Passivhaus certificate, not only is thermal insulation of the enclosure essential, but so is water-tightness, which is a basic premise of this standard. Polyurethane is the most...

Buildings that follow the Passivhaus standard are designed for optimal energy efficiency. Thus, it is possible to reduce the energy consumption to the minimum, reaching up to 90% of what a conventional building needs. Buildings are the source of nearly 40% of the...

The term Passivhaus comes from the German expression “Passive House”. It was in the 1980s that this concept was developed and it has led to a standard for low energy housing construction, that is more current than ever.

Thermal bridges reduce the thermal resistance of the elements that form the building envelope. In addition to energy losses, a thermal bridge implies the risk of condensation and the presence of mold in winter.

Energy efficiency is the key feature of a sustainable building and consists of achieving a design that guarantees a reduced energy demand over time.

The optimal thermal insulation of the envelope plays a fundamental role, together with the closing of gaps.

Passive houses must meet high demands in terms of thermal insulation and airtightness. By creating an envelope as linear as possible, we can avoid unwanted air infiltrations. To achieve this goal, it is necessary to pay attention to the sensitive constructive points...
