At SDG our knowledge of the impact of the correct acoustics in different environments grows it is no surprise that the education sector is one area where you can’t afford to be complacent.

I spoke to Ciaran Donnelly and after a few subsequent drawings emailed back and forth we agreed on the detail. SDG had the assembly on site within 3 days and saved us a lot of time on site with cutting and welding. We were able to lower the assembly into place in one piece with no concerns. I would most definitely engage in this service again.
