Flex 365 is a flexible, single-component, all-season polyurethane foam, suitable for the installation of wooden, PVC or aluminium frames and shutters. Thanks to its permanent elasticity and compressibility, it absorbs vibrations and small movements of the structure, compensates for the thermal expansion of the substrates, prevents heat loss and water infiltration and provides thermal and acoustic insulation at primary and secondary joints of windows and doors. The use of a special mixture of propellants allows it to be used at ambient temperatures as low as -10 °C. It complies with the performance characteristics identified by UNI 11673-1 “Installation of doors and windows” as regards sound insulation parameters, air permeability, vapour permeability, elongation at break, elastic recovery and volume loss. Post-expansion is practically zero. This characteristic has a twofold advantage it avoids tensile stresses that cause misalignment of the counterframes and makes it unnecessary for any second “pass” to complete the filling. Flex 365 is a viable alternative to the use of multi-purpose tapes, especially when joint insulation is combined with the need to glue the joints.
