What are Double Glazed Windows?
Double glazed windows, known as IGU, are windows that have two panes of glass that are separated by a spacer that is filled with Air, Argon or Krypton gas.
Argon gas performs better than air and has low conductivity, which is what you want.
The optimum thermal gap between the panes of glass should be minimum 12mm.
Double glazing adds an insulation layer, which means that your home stays cool in summer and warm in winter.
It’s important for your double glazed windows and doors to have non-conductive properties, which means they don’t attract heat and cold, such as our multi chamber uPVC profiles that use both re-enforced steel and patented advanced composite materials.
For climates that are very cold such as the snow, you might want to consider our triple glazed window and door options, which offer even better thermal and noise insulation.
