We’ve invested more than 2 million pounds in two Forel Vertical IGU-Lines at our Padiham IGU manufacturing facility.
Automatically applying the spacer bar to the edge of the glass sheet with an ultra-high level of accuracy, this equipment achieves an instant and far better bond, than traditional spacer systems, maximizing thermal performance.
Combined with a highly accurate final seal on units, the next-generation process cuts the likelihood of IGU failure, which means you don’t get call backs!
