About Teutemacher Glas und Spiegel
Teutemacher Glas und Spiegel is a family business founded in 1920 in Warendorf with two operating companies, Teutemacher Glas GmbH (production) and Teutemacher Glas- und Metallsysteme GmbH & Co. KG (assembly and service). In its own plant, the company has been producing insulating glass since 1972, as branded glass under the ISOLAR name since 1986, including thermal insulation, solar-control and sound-protection glass as well as fire-protection and attack-resistant glazing. In addition, the company manufactures its own toughened safety glass (ESG, ESG-H, TVG), processes laminated safety glass (VSG) in an autoclave, produces mirrors, performs lead glazing, and finishes glass through enamelling, screen printing and ceramic digital printing. Teutemacher Glas- und Metallsysteme also manufactures and installs windows, doors and façades in aluminium, glass balustrades and all-glass railings, fire-protection doors based on Schüco systems, as well as shower enclosures, glass doors and partition walls. Over 100 glass types are permanently in stock. The delivery area covers the Münsterland, East Westphalia, the Sauerland and the Ruhr region; customers include building owners, commercial customers, administrations and medical practices.

Materials and Processes
Insulating glass (ISOLAR double and triple glazing)
In-house production since 1972 with functions such as thermal insulation, solar control, sound protection and object protection, individually or combined.
ESG toughened safety glass
In-house toughening production for elevated static, dynamic and thermal loads, e.g. façades, doors and interior fit-out.
ESG-H with heat soak treatment
Reduces the risk of spontaneous breakage due to nickel sulphide inclusions, mandatory from 4 m installation height and in structural glazing.
TVG heat-strengthened glass
With a coarse fracture pattern and high residual load-bearing capacity, ideal for VSG in overhead glazing and point-fixed glazing.
VSG laminated safety glass
Produced in an autoclave under heat and pressure, with highly tear-resistant interlayers for anti-burglary and object protection.
ISOLAR ARDOREX fire-protection glass
Fire-protection glazing with general building authority approval for fire-protection doors and gates.
Float glass and design glass
Over 100 glass types are in stock for interior fit-out, furniture construction and object furnishings.
Aluminium
System profiles and façade constructions, e.g. anodized system profiles for glass balustrades.
Stainless steel
Handrails and components for all-glass railings and glass balustrades.
