抗风压性能   The  wind  pressure  resistance    5000pa

抗空气渗透性 The  air permeation  resistance    0.6m3/(m.h)

抗雨水渗漏性  The  rain  resistance   400pa

保温性能      The  heat  preservation  2.99w/(m2.k)

1.隔热性能   Heat  insulation

 采用断热冷桥工艺处理，将铝型材分成内外两个整体看待，内外两支型材之间以聚酰胺尼龙加玻璃纤维绝缘聚合物作为隔热条进行结合，从而在铝合金型材的内外侧之间形成有效断热层，隔断内外的冷热交换，使通过窗框或内扇型材散失热量的途径被阻断，达到高能效的断热目的.

中空玻璃之间形成静止干燥气体隔热空间的整体玻璃结构.

静止气体隔热层热传导系数比任何材料都低.因此中空玻璃的选用更加使得节能性大大提高.

   The  heat-cold  insulating-bridge treats aluminum profile as two entireties , the interior entirety and the exterior entirety .The two entireties are combined with polyamide nylon and fiberglass insulating polymer as heat-insulating strip. An effective heat-insulating layer is formed between the interior and exterior aluminum alloy profile to cut the heat-cold exchange. Therefore ,the purpose of highly effective heat insulation is achieved.

  The combination of hollow glasses and frames form the insulating layer that contains steady and dry air.

  Steady air heat insulating layer has very low heat transfer coefficient. Therefore, the usage of hollow glasses will dramatically improve the energy efficiency.

2.抗风压性能   The characteristic of resisting wind pressure

 双料设计

    内外两支料的设计应用较之单料无疑在强度上更是加强.特别设计的加强型横档料更是提高了窗的整体抗风压性能.所以3500型珐琅节能平开气密窗也适合做大型的落地窗.景观窗.

   Double transverse design

       In comparison with the single transverse, the double design is undoubtedly increased the strength of the structure. This special design of intensified transverse material improves the wind resiting property. The 3500 series ganoid energy –saving side-hung airtight window is suitable for being made into large French style windows and sight windows.

3.内倒又内开防盗又通风    Inward falling and opening Theft-proof and air ventilation

    内倒的开启方式最适宜夜间.冬季使用.内倒的小角度开启时,除了方便室内外清新空气互换，同时还能保障室内的安全，防止小偷从窗处入室。

     The window with the inward falling and opening mode is especially appropriated for use at night and in winter. When the small angle of inward falling is opened, it is convenient for exchange of fresh air, and it can also prevent thief from going into the room..
