TP652 Multi-functional sealing tape

TP652 is a flexible polyurethane foam impregnated with flame-retarding modified synthetic resin. It differs from standard impregnated foams due to the innovative illbruck composite step technology.
This multi-functional sealing tape is used to provide an airtight and driving rain-resistant seal to window and door joints while also having thermal-insulating properties across the entire depth of the perimeter gap. The newly developed inner step band and the greater interior compression from it meets demands in Passive Housing, new building and renovation. TP652 meets the requirement “tighter inside than out“ in relation to water vapour diffusion according to the RAL assembly guidelines.
