The aluminum doors and windows of bridge cutoff have good thermal insulation. The inner and outer frames of thermal insulation profiles are combined with soft ones. The frames are made of one rubber strip and two wool strips with three sealing forms. They are tightly closed, airtight and watertight, and have excellent heat preservation performance. The window sashes are made of hollow glass structure, which makes the windows truly show excellent sound insulation, heat insulation, heat preservation and function, and saves a lot of heating and cooling costs. The heat transfer coefficient K value is below 2.23-2.94w/2k after testing, The energy saving effect is remarkabl
