The steadily growing needs for living comfort and energy efficiency often conflict with the requirements for authenticity and conservation when it comes to the modernisation of existing buildings. Windows and glazing hold an important position in this process and require particularly sensitive handling. When replacing single glazing in favour of modern insulating glass, this often results in the loss of the historical glass and, as such, also in the loss of the stylistic unity of glazing, window frames and façade.
The use of LambertsGlas® restauro® in insulating glass units combines the advantages of modern glass technology with the unique character of mouth-blown flat glass and therefore enables the external and internal appearance of a historic building to be preserved.
restauro® is handmade flat glass fabricated through the expertise of traditional techniques. The glass forms the basis for the various types of insulating glass of the Glashütte Lamberts.
restauro®ISO has the typical surface of mouth-blown glass with slight or more pronounced distortions and scattered bubbles. It is ideal for the energy conservation upgrades required for historic buildings.
restauro®ISO is a combination of a pane of mouth-blown glass and a low-e coated float glass pane. The space between the panes is filled with an inert gas. The unit‘s heat insulation values are comparable to commercial insulated float glass units.
restauro®ISO is available in ultra-thin 8mm thick (2-4-2 construction) glazing units and can thus be used in narrow historical window glass frames as well.
restauro®ISO can be custom fabricated with colored spacers to approach the colour of the window frame.
restauro®ISO can also be produced in technically exacting ratios thanks to thermal toughening of the mouth-blown glass.
restauro®ISO combined with special laminated float glass can be processed further into sound-insulating glazings (restauro®dB) as well as burglary protection glazings.
