3M Glass Defect Repair Kit Reduces Costs Tenfold At Major New Commercial Building
When the panes of glass on a major new commercial
building in Northern Ireland became badly scratched as a result of
careless cleaning, insurer Dawson White faced a potential bill of
around £1.4 million to replace them.
However, thanks to the innovative Glass Defect Repair System from 3M, the diversified technology company, and the work of 3M’s approved Irish partner, Dublin-based Glass Polish, that figure is being reduced by around tenfold.
A project by Harcourt, the seven-floor Citibank building in Belfast’s Titanic Quarter features a total of 363 panes of 15mm toughened structural glass, each measuring 1.8 metres x 1.2 metres.
The installation had run smoothly but the final cleaning of the exterior glass generated major problems when misuse of scraping equipment by the contract cleaner created scratches in the vast majority of the panes.
The insurers first thought that all the glass would have to be replaced, leading to significant cost and a major delay to the project’s completion. However, having consulted with Glass Polish, the possibility of repairing the scratches became real.
Glass Polish was able to demonstrate the benefits of 3M’s Glass Defect Repair System – a modestly-priced kit consisting of a rotary polisher and a series of abrasive discs in reducing grades of coarseness. These discs employ 3M’s highly innovative three-dimensional Trizact technology which continually exposes fresh mineral at the surface as the abrasive wears, ensuring consistent performance over large areas of repair. The result of years of development, the kit can repair even deep scratches and scuffs with no negative impact on the integrity of the glass – and, unlike other glass repair systems on the market, it does not require the use of messy cerium oxide slurries or impregnated pads.
Glass Polish’s professional team is now undertaking the repair of all of the scratched panes using the 3M product. The fact that the panes can remain in place is allowing work to continue uninterrupted in the Citibank building.
Harry Mathews of Glass Polish Ireland explained: “Replacement of this amount of glass would have been hugely expensive as well as creating a delay of several weeks while new glass was sourced – to say nothing of the installation time and cost for the new panes.
“The cost of the repairs is likely to amount to around £140,000 but this is a relatively small consideration compared with the estimated £1.4 million that the replacement glass would have cost to purchase and install.”
He added: “For many years, even minor damage on structural glass resulted in its replacement, with a commonly held view that any scratch clearly felt by a finger nail was too big to be safely repaired. The 3M Glass Defect Repair Kit is simple to use and we are finding it can remove very deep scratches and other damage with minimal operator effort.”
