铝合金门窗具有较高的强度及良好的水密性，气密性，隔声、隔热性能。型材表面经氧化处理后具有优良的耐腐蚀性能。
铝合金门窗种类繁多，规格齐全。有 45 系列， 50 系列， 73 系列， 90 系列， 100 系列等。有固定窗、平开窗、推拉窗、上悬窗、中悬窗、百叶窗和各种异形窗；有平开门、推拉门、弹簧门和玻璃幕墙。
主要技术性能指标
1 、抗风压性能
在压力为 2500Pa 作用下，框扇最大变形量（挠度）小于两支点间跨度的 1/160 （高度在 100 米以下的建筑处理后，抗风压性能还可以大幅度提高。
2 、水密性
铝门窗均有双面橡胶条密封，并没有简单科学的排学系统，门 —— 窗，门 —— 门组合处有密封膏密封，水密。当喷水量为每分钟 3.5 公升 /m 2 ，均匀分布在窗的表面上。相当于级大风，风压 220Pa ，风速 18.76 米 / 秒，时间 90 分钟。未发现任何漏水现象（推拉窗），试验时间 90 分钟。未现任何漏水现象（平开窗）。
3 、气密性
当压力为 500Pa ，相当于是 11 级大风，风速 28.28 米 / 秒，其框扇压合处缝隙漏气量平开窗小于 8.72m 3 /nm 2 ，小于 19.38m 3 /nm 2 .
4 、隔音性能
音频 f 由 100-4000HZ, 用 ISO 方法，其脉动值﹤ 8db ，总值大于 32db ，实测结果，隔音指数为 28db （单层玻璃加大脉动值，双层玻璃隔音指数﹥ 34db 。
5 、保温性能
实验条件：室外气温 0 度，相对湿度 50% ，风速 5 米 / 秒 4 级风，室内气温 20 度，相对温度 40% 。试验窗外形尺寸 1600×1300mm Q1—— 通过玻璃的热损失； Q2 通过铝框扇的热损失； Q3 因空气渗透造成的热损失
试验结果：
单玻璃热损失 Σ=Q1+Q2+Q3=208.8+34.16+36=273 千卡 / 小时
双玻璃热损失 Σ=Q1+Q2+Q3=108+34.16+36=178 千卡 / 小时
Aluminum windows and doors with high strength and good water tightness, air tightness and sound insulation, thermal insulation properties.The surface profile after the oxidation treatment has excellent corrosion resistance.
A wide range of aluminum windows and doors, and complete specifications.45 series, 50 series, 73 series, 90 series, 100 series and so on.Fixed windows, casement, sliding window, hanging on the window, hanging in the window, blinds and a variety of special-shaped windows; swing gate, sliding door, spring door and glass curtain wall.
The main technical performance indicators
1, the performance of wind pressure
In the pressure 2500Pa role, box fan maximum deformation (deflection) is smaller than the two points between the span of 1/160 (the height of the building 100 meters processing performance of wind pressure can also be greatly improved.
2, water tightness
Aluminum windows and doors are double-sided rubber strip sealed, and no the simple scientific row school system, doors - windows, doors - door combination at the the sealant sealed, watertight.When the water spray amount of 3.5 liters per minute / m 2, is uniformly distributed in the surface of the window.Equivalent gale wind pressure 220Pa wind speed of 18.76 m / s, a time of 90 minutes.Did not find any water leakage (sliding sash), test time of 90 minutes.Not currently any water leakage (casement).
3, the airtightness
When the pressure of 500Pa, equivalent to 11 winds, the wind speed of 28.28 m / s, slit leak amount of its box fan lamination at casement window is less than 8.72m 3 / nm 2, less than 19.38m 3 / nm 2.
4, sound insulation
Audio f 100-4000HZ ISO method, its pulsations value <8db a total value of greater than 32db, measured results, noise index 28db (single glass increase the fluctuating value, double-glazed soundproof index> 34db.
5, the insulation performance
Experimental conditions: outdoor temperature of 0 degrees, 50% relative humidity, wind speed of 5 m / sec, 4, the wind, the indoor temperature is 20 degrees, the relative temperature of 40%.Dimensions of the test window 1600 × 1300mm Q1 - heat loss through the glass; Q2 through the fan the heat loss of the aluminum frame; Q3 caused by heat loss due to air infiltration.
Test result:
Heat loss of a single glass Σ = Q1 + Q2 + Q3 = 208.8 +34.16 +36 = 273 kcal / h
Double glass heat loss Σ = Q1 + Q2 + Q3 = 108 +34.16 +36 = 178 kcal / h
