Functional doors

Customised door solutions.


According to the modular building block principle, depending on the required functionality the door the security fittings and insert can be adapted accordingly ( e.g. special insulation insert for climate class doors or steel insert for bullet-resistant doors).

We develop our functional doors ourselves (also project-related) and have them tested by renowned testing institutes.

Smoke protection and fire safety doors

Preventive fire protection

In certain buildings and areas, doors are required to offer fire-resistant, fireproof, and smoke-resistant properties in order to meet the safety requirements for preventive fire protection. The areas of application are defined and stipulated by the responsible building control authority. ComTür develops and tests its elements in-house, in some cases on a project-specific basis.

Sound insulation doors

Keeping things quiet

There are minimum requirements that apply to the required airborne sound insulation of doors between certain areas and rooms to prevent sound from outside apartments and external work areas from penetrating inside. Depending on the area of use, these are divided into the sound protection classes SK1-SK4 with corresponding sound insulation values.

100 years of experience in building doors

Since 1919 we have been manufacturing high-quality doors at our door factory in Heilbronn. Our doors stand out with exceptionally high-quality finish, surface quality, and the use of exclusive components.

Climate control doors

Controlling climatic influences

Due to the effects of the climate, wood used as the door material – and therefore the door leaf itself – can warp. This can happen on apartment entrance doors, front doors, or wet room doors that are exposed to different climatic conditions on the inside and outside.

Bullet-resistant doors

For ultimate safety

Bullet-resistant doors are used in areas where increased requirements apply in terms of safety against burglary and attacks. Examples of this include branches of banks and building societies, airports, police stations, ministries, and embassies. Increasingly, the use of bullet-resistant doors is now also required in the hotel and catering industry.
