      ?(What is rigid polyurethane foam (PUR/PIR)
 
Rigid polyurethane foam (PUR/PIR) is a closed-cell plastic. It is used as factorymade thermal insulation material in the form of insulation boards or block foam, and in combination with various rigid facings as a constructional material or sandwich panel. Polyurethane in-situ foams are manufactured directly on the building site

In modest material thicknesses, rigid polyurethane foam (PUR/PIR) offers optimal thermal insulation coupled with an exceptional space-utility advantage.
For architects and planners, rigid polyurethane foam (PUR/PIR) allows scope for creative insulation solutions from the cellar and the walls through to the ceilings and the roof. It is ideal in the lightweight, low-energy or zero-energy building approach (Passivhaus).
 

:Insulation Boards

Thanks to their excellent mechanical strength, insulation boards made of rigid polyurethane foam (PUR/PIR) are highly resistant; they can be combined with other materials and are easy to install on the building site
 

:Metal Faced Sandwich Panels

Sandwich panels have a rigid polyurethane foam (PUR/PIR) core with profiled and in most cases metal facings on both the upper and lower surfaces. Sandwich panels are particularly suited for roofing and wall applications, for the various support structures in halls and industrial buildings, as well as for refrigeration and cold-storage units. The lightweight panels are easy to process and can be installed in all weather conditions. PUR/PIR sandwich panels are to a high degree pre-fabricated, giving them structural and constructional design properties that offer a high level of security, both in the processing stages and in the finished building

:Blocks

Polyurethane (PUR/PIR) block foam can be cut to shape for the insulating building equipment and industrial installations

:In-situ Foams
In addition to factory made polyurethane rigid foams (PUR/PIR), in-situ foams are also used in building. They are produced with state-of-the-art equipment "in situ" on the building site itself. In-situ foams are mainly used for technical insulation applications. The in-situ foam is sprayed onto the desired surface or poured into moulds, producing a seamless structure
