Why is the seal in double glazing important?
Ensuring that the double glazing unit remains airtight is very important. Any moisture getting inside will compromise the performance of the unit. Not to mention the view!
Simply clipping, sticking or even gluing on another layer of glass (or plastic) will not cut it for durability and performance.
Everyone wants a warm, comfortable home, with windows that last a long time and always look great. It sounds so simple – but achieving all these objectives is a big ask.
Windows have to put up with a lot. They face wild swings in temperature from summer to winter, as well as harsh New Zealand UV rays, barometric pressure changes and blasting winds. To construct a double-glazing system that stands up to this treatment year in and year out, you need to incorporate some pretty clever technology.
The Double Glazing Company has sought out manufacturers here in New Zealand that provide the best performing double glazing units on a global scale.
The double glazing units that we use has outstanding durability, partly due to the design of the seal. It contains a structural seal on the inside. This takes the form of a pressure sensitive acrylic adhesive and is backed up by hot-melt butyl. The butyl must be heated to temperatures of 180oC as a part of the spacer-to-glass welding process.
The result is two lines defence against gas and moisture, with the durability to keep on working for years to come.
