The U-factor is the first thing to consider. The wind that flows through windows is usually represented by the U value. The low the number is, the better the blocking of heat flow. Air infiltration is another very vital factor that one must consider when searching for the ideal windows.
Solar heat gain co-efficiency is used in measuring the amount of solar heat that is transmitted. When the SHGC value is very high, it means that there is more solar heat that is being transmitted through the glass window. If you reside in an area with a cold climate, it is advisable that you opt for the high SHGC windows and lower numbers of SHGC will be perfect for the warmer places.
The design pressure rating of windows will have a myriad of variables. The DP test is what is used in measuring the strength of the window to withstand the penetration of water or strong winds. It is wise that you buy windows with the gold certification label.
Air loss happens near the window frames or doors; it, therefore, makes a lot of sense that the airtight windows will make the best insulators.
