Experts use “Slimline”or “Vacuum “glass (such as LandVac or Fineo), which provides the thermal efficiency of contemporary systems but with a profile as thin as 6mm– 10mm. This permits the glass to fit into traditional glazing bars without lookinglarge. Specialized Draught-Proofing Systems One of the main problems relating to old sash window s is the” rattle” and the “chill.” Experts install discreet brush stack systems into the staff and parting beads.
