Why Polyurethane?

Thermal insulation is designed to limit heat loss during winter and reduce overheating during summer. This translates into lower energy consumption, improved indoor comfort and reduced emissions associated with heating and cooling buildings. A well-designed building envelope also helps meet increasingly demanding energy-efficiency requirements and represents a long-term investment in the performance and value of the building.

Polyurethane Foam – Ediltec Thermal Insulation – Why POLIISO?

Among the insulation materials available today, PIR (polyisocyanurate) stands out for its high thermal resistance, making it possible to achieve excellent insulation performance with reduced thicknesses. This is particularly important in both new construction and renovation projects, where available space can be a significant design constraint. The technological development of Ediltec insulation boards has also led to declared thermal conductivity (λD) values as low as 0.022 W/m·K, enabling high levels of energy performance with increasingly efficient insulation solutions.

More performance, less thickness

One of the main advantages of PIR insulation boards is their excellent relationship between thermal performance and thickness. For the same required level of thermal resistance, thinner insulation solutions can be used compared with materials with higher thermal conductivity, helping to preserve usable space and optimise the overall build-up. The low weight of PIR boards also facilitates handling on site and can make installation faster and more efficient.

The performance of an insulation board does not depend solely on its insulating foam core. The type of facing also plays an important role and can be selected according to the intended application.

Ediltec offers different facing solutions designed to meet the requirements of roofs, walls, floors and other specialised applications while maintaining high thermal and mechanical performance.

This versatility makes it possible to identify the most appropriate solution for each project without compromising energy efficiency.

Performance designed to last

Choosing an insulation system is not simply a matter of considering its initial thermal conductivity value. Its ability to maintain the required performance throughout the service life of the building is equally important.

For this reason, the insulation system should always be evaluated as a whole, taking into account material quality, appropriate design and correct installation.

The video explores these principles, providing a clear overview of the characteristics that make PIR one of the leading technologies for high-performance thermal insulation of the building envelope.
