Windows ETC have been in the glazing industry for over 30 years. They started Windows ETC because they wanted to give the industry a client focused business that cared about each relationship, large or small. Windows ETC has an ‘ETC’ because they realised that there was more to giving great service than just supplying the windows.
Windows ETC set out to provide the region’s best and most innovative trade and retail glazing showroom. They want to ensure that fitters, builders and homeowners get to see the latest leading products in a comfortable, pressure free environment.
Windows ETC provide a space where you can view Rockdoors in a comfortable atmosphere and make informed choices.
