Energy SavingsConsidering Triple Glazed Windows?

As energy requirements for windows continue to advance, the demand for higher-performance windows is greater than ever before.

Have you ever wondered why Centra drills a 1/8" hole in the middle pane of a triple-glazed IGU? This is so the pressure from one cavity can equalize with the other. When the temperature on the outside is colder than the inside, the pressure in each cavity will be different. This puts added stress on the seals. The hole allows the air pressure to equalize, eliminating this stress on the seals and resulting in a better performing product. 

This was developed as a result of failure analysis many years ago. Watch out for window companies making their own triple pane units as they will NOT have this feature. We would predict a sealed unit failure at twice the rate without this hole. Protect your investment. 

If you are serious about getting the best quality, best energy savings, and best value in today’s window replacement market, then you need to do your homework. Centra has modelled over 300 glass and frame scenarios in an effort to find the best performance coupled with a cost-effective solution. When it comes to windows, we're the energy efficiency experts.
