●HTSafe is the successor product of HT. Thanks to many improvements, it can be used in all areas of building construction.●HTSafe meets fire protection class B1 and is therefore considered flame retardant.●HTSafe meets all sound insulation levels from I to III and is therefore applicable in single-family homes, residential and commercial properties and hospitals.●Approval is not required, as HTSafe is manufactured according to European standard DIN EN 1451-1.●Thanks to the great success on the market, the manufacturer has now phased out the standard HT and is now replaced by the naturally backward compatible HT Safe system.[DN 40 Gray]
