PU enables pitched roofs to be insulated over or below the rafters. The robust PU insulating boards used over the rafters also serve as a weatherproof layer during construction work. As PU is a particularly thin insulating material, it makes economical building designs possible, and the lightweight but highly stable PU insulating boards are easy to handle.
The increasingly strict thermal insulation requirements for new and existing buildings can lead to ever-thicker insulating layers. But for flat roofs this can be problematic, e.g. in the case of skylights. High-performance PU provides effective insulation in a thinner insulating layer.
Faҫades can be insulated very economically and efficiently using composite PU thermal insulation systems. The advantage here is once again that PU makes a much thinner insulating layer possible. A faced brickwork façade featuring PU as core insulation is not only a visually attractive solution but also a practical one, as the PU layer is much thinner than alternative insulating materials. A façade insulated with PU can actually achieve passive-house standard. And if the outer wall of a listed building cannot be insulated, PU is a practical and economical solution for interior insulation.
PU metal-faced sandwich panels are extremely light but robust prefabricated parts for roof or wall systems, offering the great benefit of a three-in-one support, sealing and insulating solution. These panels offer architects a high degree of flexibility and builders speedy construction. With state-of-the-art coatings the panels also offer good anti-corrosion and UV protection. And from a lifecycle perspective they are extremely economical thanks to their minimal maintenance and attractive energy-saving performance.
