Product Description

Doorwin windows are made with a variety of high-performance glazing options to meet your energy performance and budgetary needs. For all windows and doors exported to North America, we provide fully heat-treated, tempered glass as standard.  This provides extreme impact resistance to prevent glass breakage, reducing warranty claims.  When broken, tempered glass uniformly shatters into small pieces for safety. Our standard glazing for the North American market is SGCC (Safety Glazing Certification Council and IGCC (Insulating Glass Certification Council) certified for performance and safety.


Glazing performance is a key factor in lowering a structure’s overall energy usage.  The glazing unit determines three factors that affect energy efficiency and comfort: 


1)     The flow of energy via thermal conductance.

2)     The transmission of light which affects visibility, and the amount of solar heat gain.

3)     The transmission of sound.


Experts estimate that 70 percent of energy loss occurs in windows and doors and 90 percent of window heat loss occurs through the glass.  Triple glazing, low-E coatings, argon gas fill and warm edge spacers can improve the energy efficiency of glazing units by 40 to 50% to deliver maximum insulation, solar heat gain control, condensation resistance and UV protection. 


Our team will work with our clients to develop customized glazing configurations to meet any project requirement.
