Aluminium sash windows have a clear place in heritage and conservation work, but their potential extends much further.
With a flush opening and no projection into or out of the building, the system is practical for commercial applications such as schools and hospitals. Its natural ventilation characteristics also make it suitable for high-rise buildings.
Martin Halford, Managing Director of Mercury Glazing, explains:
“For us, this versatility is particularly important because aluminium now has a much broader reach, from premium domestic and heritage refurbishment through to education, healthcare and larger commercial projects.”
