Custom-made fire protection contour cuts made of flexible foam for situations where dimensional tolerances of system components need to be compensated. The moulded parts are delivered cut to size at the factory. Individual mats can be bonded together to form larger areas. Thanks to the elasticity of the mats, they adapt flexibly and compensate for dimensional tolerances. Alternatively, the mats can be easily cut to size with a conventional insulation knife, which allows for easy installation at the installation site.
