FGS went into administration last month with the loss of 200 jobs.
The new national Special Projects team of eight will work on high level, complex and bespoke works for GG Glass.
Sam Grant, Operations Director at GG Glass said: “Special Projects will offer bespoke works, often requiring prefabricated units, specialist access equipment and a very specific skill set.
“The team we have appointed have already established a sound business model that was in its very early infancy before the collapse of FGS.
“For us, taking on the team and establishing our own division made huge sense.
“Not only are we adding an important service stream to our business but we have the opportunity to take on a highly skilled and experienced group of people whilst strengthening our own team and the wider business.
“The focus of Special Projects will sit very much in-between our current service streams, Contract Glazing and Emergency Glazing, and can be considered more complex and detailed than much of our current work.
“The launch of the division is a great move for GG Glass as we continue to consolidate our position as the commercial glazing contractor of choice for the industry.”
