Make no compromises with foam sealing tape

Dur­ing the cold sea­son, res­id­ents may feel a cold draft even when the win­dows are closed and the heat­ing is on. The reas­on could be a front door or bal­cony door that has not been prop­erly sealed. There­fore, when installing a new door or repla­cing the old one, the joints should always be closed with a spe­cial seal­ing tape (also called back­er rod), con­sist­ing of pre-com­­pressed flex­ible foam. This not only pre­vents annoy­ing drafts, but also pro­tects against noise and driv­ing rain.

Tip 1: Install the sealing tape along with the door

Once the door has been expertly installed, seal­ing plays a key role. In order to pre­vent later dam­age caused by driv­ing rain and oth­er weath­er con­di­tions, the joint between the door and the wall should be filled with a seal­ing tape. How­ever, if the door is already in place, the tape can­not be applied sub­sequently. It is there­fore import­ant to insert the joint seal­ing tape already dur­ing door install­a­tion. The pre-com­­pressed foam expands around the door frame and forms a tight seal with the joint edges. Being coated with a water-repel­lent syn­thet­ic res­in, it effect­ively pro­tects against driv­ing rain but also noise.

Tip 2: Buy a compatible foam sealing tape

When choos­ing a joint seal­ing tape, make sure that it is com­pat­ible with the struc­ture and mater­i­al of the out­er wall. Also the required min­im­um joint width should be observed. A fre­quent mis­take made espe­cially in the case of doors is to use not enough mater­i­al for seal­ing around the door peri­met­er. This cre­ates gaps through which water and wind can pen­et­rate.
