restauro® - Handmade Window Restoration Glass / Mouthblown Cylinderglass



Genuine Lamberts Restoration Glass is specially crafted traditional window glass to meet the requirements for renovation of old buildings, the preservation of historical monuments and restoration of antique furniture.

Until the early 20th century, all window-glass used to be  manufactured by gaffers with blowpipes. Glashütte Lamberts has preserved these production techniques and provides the authentic charakter of historic window-glasses until today.

Mouthblown original Lamberts Restoration Glass is an indispensable part of every glazing restoration, that requires the original air of historic windows.

The special features of our restauro®-window glass:The mouth-blown Lamberts Original Restoration Glass (so-called cylindrical glass / cylinder stretch glass) is an indispensable component of any restoration project which needs to satisfy the requirements for this classic type of glazing.

There are a multitude of further processing options for our mouth-blown window glass. Is can be used as a hardened (pre-stressed) single pane, as an outer pane in insulating glass or as laminated glass.

The result is a perfect symbiosis between contemporary thermal insulation and historically correct appearance.

Handcrafted window glass is used whenever the sharp and hard reflections of machine-made glass are to be avoided in order to preserve or regain the original appearance of historical buildings.

Our handmade and mouthblown restoration glasses restauro® are used in listed and period buildings where the glass must look authentic.  With movement and the occasional bubbles, restoration glass has much more life to it than modern float glass. It is just perfect for sash windows, leaded lights and Orangery windows.

Depending on the period and architectural style (Romanesque / Baroque / Rococo / Classicism / Historicism / Art Nouveau / Bauhaus Style / New Building and Modernism), we offer you the appropriate glass.

The preservation of historically valuable buildings is of great importance today. The window and its effect have a considerable bearing on the appearance of a building facade.

In terms of monument preservation, restoration with preservation glass manufactured according to original procedures is the only safe and correct way!

Alternative, machine-made, historicizing products on the other hand, often clearly disfigure an old building facade!

Glass produced according to the original mouth-blowing procedure fits into the facade easily and unobtrusively. Replacement products from industrial production, on the other hand, are immediately obvious and irritating to the eye, due to the regularity of their appearance and reflection!

The repair and maintenance of historic window constructions requires a high level of craftsmanship and knowledge.
