It meets the stringent requirements of DIN 4102 Part 1 for construction materials, achieving a B2 classification. Once cured, the foam can be cut, sawn, or plastered over within an hour, provided the working temperatures (both the can and surfaces) are between +5°C and +30°C, with an ideal temperature of 20°C. It is designed for easy application using the included straw gun and offers a fire rating of up to 240 minutes in certain configurations, as tested according to BS 476 Part 22.
