ISO-Chemie has a great new addition to its in-front-of-wall installation system. These boards can be used to produce special design components when fitting windows in the outer thermal insulation level.

ISO-TOP CONSTRUCTION SHEETS WF3 are made from high-density THERMAPOR, i.e. the same material as the TYPE 3 from the ISO-Chemie in-front-of-wall installation system. These boards can be customised and adapted as required to create installation and sealing details in the ISO-TOP WINFRAMER IN-FRONT-OF-WALL INSTALLATION SYSTEM. They can be used either as adapter boards in combination with the system profiles or individually as supporting profiles, packing strips or window sill shaped parts. They can also be used to adapt roller shutter casings and venetian blind boxes. With a strength in excess of 650 kPa, the ISO-TOP CONSTRUCTION SHEETS WF3 offer excellent load-bearing capacity for a window or door.


The boards are available in thicknesses from 20 to 100 mm and can be sawn or cut to size and shape to suit the specific needs on site.


The ISO-TOP CONSTRUCTION SHEETS WF3 can be combined with components of the ISO-TOP WINFRAMER in-front-of-wall installation system and provide the ideal basis for 3-level sealing with multi-functional joint sealing strips or the other products from the ISO³-WINDOW SEALING SYSTEM from ISO-Chemie.
