Replacing your single glazing with slim double-glazed units

Fineo glass is a revolutionary new glazing product which, at 7 mm thick, can accommodate the narrow rebate of a period sash window. We can also reinforce old sashes to carry the weight of a new glass unit without compromising the integrity or appearance of the window to help the glass fit. This lightweight and the narrow pane will not affect the balance of the windows but will block out noise and draughts and keep your heat where you want it – inside.

Why not enjoy the many benefits of double-glazed sash windows with the thermal properties of standard triple glazing for the sash windows on your Hertfordshire home without changing this valued and elegant characteristic of traditional windows.
