DGC: Double Glazing Conversion
DGC is a specialist treatment applied to existing single glazed windows where the timber frames are of suitable condition and depth.

To explain simply, Sash Windows Expert removes the frames, extracts the existing single glazing and replaces with sealed unit double glazing. We do this by rebating the timber frames enough to take the extra depth of a double glazed unit.

This is a skilled operation carried out on site, using specialist jigs fitted into our vans. There is no delay, single glazing is substituted for double glazing and your existing frames and new glazing is re-fitted, draught proofed and finished, leaving you with a superb solution at a fraction of the cost of totally new windows!
