Reliable foam-filling of connection joints

illustration purposes only

The highly elastic PUR spray foam for consistent thermal insulation in the functional area

ISO-TOP ELASTIFLEX is a highly elastic PUR spray foam which is about three times more flexible than conventional PUR foams on the market. The high flexibility significantly reduces the risk of the foam cracking in the joint, and thus guarantees thermal and sound insulation long-term on the functional level. Thermal elongation of patio doors, lift-and-slide doors and large-size construction elements can be fitted easily thanks to the high flexibility of the PUR spray foam. ISO-TOP ELASTIFLEX guarantees a high wind-tightness of connection joints and can be processed at temperatures down to -10 °C. Low volume loss and very good form stability are further positive characteristics of ISO-TOP ELASTIFLEX.

Application Areas

Reliable foam-filling of connection joints

ISO-TOP ELASTIFLEX is extremely suitable for the permanently elastic foam-filling of the connection joints of window and door frames in accordance with Building Energy Act, DIN 4108-7 and the RAL “Installation guide” for windows and external doors. When ISO-TOP ELASTIFLEX is used correctly, the risk of foam cracking in the connection joints on gables, purlins, eaves, roof beams, dormer windows, roof windows and pipe ducts for fresh air and waste air is averted effectively.


Excellent adhesion to almost all construction surfaces

The innovative special PUR spray foam can be applied to all standard construction surfaces such as concrete, masonry, stone, plaster, timber, corrosion-protected metal, polystyrene (EPS and XPS), PIR/PUR rigid foam, polyester and rigid PVC. The adhesive surfaces must have a sufficient load-bearing capacity and be clean, dust- and grease-free. Dry surfaces should be moistened slightly to improve adhesion and curing as well as the foam cell structure.
