Comprehensible and realised


The majority of the doors and windows that leave our company are manufactured for colleagues in the joinery and carpentry trades, for property developers, interior fitters or window manufacturers. We therefore do not always know where the products are installed.

TPO products have been installed in the following properties, among others:


Hotel Edita

We supplied T90 doors for a customer, which were manufactured as framed doors in oak. The T90 doors are glazed and each has a side panel. The approx. 40 mm thick fire-resistant glass weighs around 94 kg/sqm! For this reason, it is advisable to install the glass on site after the doors have been fitted.

Old Masters Picture Gallery, Dresden

The Old Masters Picture Gallery in Dresden is one of the world's most renowned collections of paintings from the 15th to 18th centuries. A total of around 750 masterpieces are on display. The museum focuses on Italian works of the Renaissance as well as paintings by Dutch and Flemish painters of the 17th century and outstanding paintings of Old German and Old Dutch origin.

The Picture Gallery is part of the Dresden State Art Collections. It is located in the Zwinger's Semper Gallery.

Some of the doors we were asked to supply were very high and had to fulfil burglar resistance requirements. Compliance with the design and functional specifications was achieved through appropriate door constructions.

Primary school + town hall, Gräfelfing

The modern new primary school in Gräfelfing stands out for its exterior colour alone. The modern architecture continues inside. The school is also at the forefront of technology: PCs and whiteboards are also standard in this primary school.

Doors in schools are often exposed to the greatest loads and must fulfil sound insulation, fire protection and accident insurance requirements. TPO was able to supply doors that fulfil these requirements while complying with the design specifications.

State Theatre at Gärtnerplatz, Munich

The Bayerisches Staatstheater am Gärtnerplatz was opened on 4 November 1865 as the "Actien-Volkstheater" in Munich and is regarded as a "folk opera" dedicated to light entertainment. The building was reopened in October 2017 following a general refurbishment.
As part of the refurbishment, we supplied very high-quality doors and door systems, which generally had to fulfil listed building requirements in combination with other requirements. We also used arched doors and doors in escape and rescue routes.

House of Music, Regensburg

The House of Music in Regensburg is located in the former listed presidential palace, which previously housed the Lower Bavaria-Upper Palatinate state police headquarters.

Bavarian State Forests, Regensburg

The company Bayerische Staatsforsten was founded as an institution under public law. The head office is in Regensburg. With around 50 forestry operations, the company manages around 800,000 hectares of state forest, making it one of the largest forestry companies in Europe.

The company's headquarters in Regensburg is characterised by its open, bright architecture. In addition to numerous fall-protection glazings, special doors and technical requirements were supplied. The so-called "butt joint glazing" was also used for the glazing. Here, glass edges are connected directly to each other without stabilising frames, resulting in a high level of transparency.
