Aluminum-plastic-aluminum doors and windows adopt the cross-sectional structure of the composite profile. The two visible surfaces of the composite profile are made of aluminum alloy profiles. The non-visible surface is the middle insulation. The multi-chamber PVC plastic profile is used. Its advantages are not only high strength, beautiful appearance, corrosion resistance of aluminum alloy, but also the characteristics of PVC profile heat insulation, and it has very good heat insulation and energy saving effect.
"The fifth generation of new energy-saving door and window profiles is a brand-new aluminum-plastic aluminum composite door and window profile with aluminum alloy profiles on both sides and a modified multi-cavity PVC profile in the middle. Its advantage is the high strength and weight of the existing aluminum alloy. Light, beautiful, corrosion-resistant, simple processing, and the characteristics of heat insulation of plastic steel profiles, has a very good heat insulation and energy saving effect."
