Foil tape

Foil tape ..那地方不用sealant的,都是铝胶布一贴...

i saw one builder using some kind of 'glue' brushing around all vent pipe joints instead of using foil tapes. not sure what that is. i was using foil tapes to seal the joints when my house was under construction.

谢谢楼上的各位，买了两卷foil tape,把duct能看到的裂缝都封起来，希望这个冬天暖和点。
