52 series heat insulated inward opening windows

1.The appearance of the inward casement window are more flexible, and for large floor windows, the part of opening is only a small area for the whole window, which is suitable for the overall effect of the strict requirements of the building projects, especially for the effect architect required : the large grid, the pursuit of the bright and spacious, transparent effect, building harmonious and smooth appearance.

2. in the three performance of doors and windows (anti wind pressure, water tightness, air tightness), the window is better than the other ordinary windows. The anti wind pressure performance of windows depends on the resistance force of the main structures. More larger the section, more better on this point.Usually the section of casement is smaller but the main force part in the design process will correspondingly strengthen treatment so that to be sure the performance of wind resitance. The water tightness of windows depends on the sealing effect of opening parts. The casement windows on the highrise building are sealed by the EPDM rubber strip. In the aspect of air tightness, the opening sash of windows are mostly locked by two points lock, so the performance is superior to other ordinary windows. This is the reason why most commercial and residential buildings choose to use this type of window.

3.In the field of thermal insulation，this type of window is sealed with EPR.Combination of two locks for locking seal.It has better sealing effect and maximizes its thermal insulation effect.
