Adhere a nail on the air duct and then add thermal sponge with a layer of tin. Fasten it with a nail cover and then
seal the junction with tin tapes; You can also use other materials that have good insulation quality.
(2) Each air-out duct and air-return duct should be fixed on a pre-made board with iron frame. The junction of air duct
should be well-sealed in order to prevent air leakage.
(3) The design and construction of air duct should comply with national requirements.
(4) The edge of air-return duct is suggested to be more than 150mm (5-7/8 in.) away from the wall. Add a filter to the
air-return opening.
