铝包木门窗通常所说的使用功能包括：门窗的开启性能、门窗的保温性能、门窗的隔音性能、门窗的防火性能、门窗的防盗性能、门窗的风压变形性能、门窗的空气渗透性能和雨水渗透性能和雨水渗透性能、门窗的整体强度。铝包木门窗设计时，应针对铝包木门窗的不同使用场所和使用部位，确定铝包木门窗的使用功能。然后，在设计的过程中体现这些功能。为达到这些功能，通常可在选材和制造工艺两方面加以考虑。在选材上，通常选用自身破坏强度高的原材料；选择自身结构较为疏松、保温、隔音效果较好的原材料；选择不易燃火经过阻燃处理过的原材料等。
The commonly used functions of aluminum clad wood doors and windows include: opening performance of doors and windows, thermal insulation performance of doors and windows, sound insulation performance of doors and windows, fireproof performance of doors and windows, anti-theft performance of doors and windows, wind pressure deformation performance of doors and windows, air permeability and rain water permeability performance of doors and windows, and overall strength of doors and windows. In the design of aluminum clad wood doors and windows, the use functions of aluminum clad wood doors and windows should be determined according to different use places and parts. Then, these functions are embodied in the design process. In order to achieve these functions, material selection and manufacturing process can be considered. In terms of material selection, the raw materials with high destructive strength are usually selected; the raw materials with loose structure, good thermal insulation and sound insulation effect are selected; and the raw materials with non flammable fire and flame retardant treatment are selected.
