DOUBLE GLAZING WINDOWS

Sydney’s leading company fabricating and supplying a wide range of double glazed windows and in uPVC and Thermal Broken Aluminium

Double Glazed Windows

Double glazing is a popular method of thermal insulation. It consists of two glass panes separated by a layer of air that stops heat and sound from getting through. Standard double-glazed windows are very effective at thermal insulation, but somehow the sound still seems to filter through, doesn’t it? That’s because sound insulation requires a different kind of technology to accomplish. If you want to achieve up to 80% more soundproofing for your home, office, or any other premises, Ecoline Windows are the people for the job.

Why Ecoline?

Standard double glazing rarely works, at least as far as sound insulation is concerned. Most people who live in urban environments can tell you that the noise still gets through, and that’s because thermal insulation is completely different from sound insulation. We at Ecoline Glass are experts at both sound and thermal proofing and make sure that your fitted double-glazed windows offer top-level protection and insulation. To achieve this, we use better and thicker glass coupled with better layering technology and more effective layering material. The result is double glazing that works far better than either standard double-glazed windows.
