Air and water tightness

Our core competencies also include the planning and execution of window and facade tests at renowned German and European testing institutes in accordance with the corresponding valid standards. In the product standards for windows (EN 14351) and façades (EN 13830), the verifiable product characteristics are described. The verification takes place in accordance to the respective test and classification standards. The majority of the tests are carried out at our in-house testing laboratory or on-site at the building. Furthermore, we collaborate with other experienced testing institutes.

The most important tests on windows and facades are:

Air permeability

Requirements:

• according to project-specific requirements
• classification is based on the test results according to the relevant classification standard

Scope of services:
set up and execution of the test for air permeability

Water tightness

Requirements:

• according to project-specific requirements
• classification is based on the test results according to the relevant classification standard 

Scope of services:
set up and execution of the test for driving rain impermeability

Resistence to wind load

Requirements:

• according to project-specific requirements
• classification is based on the test results according to the relevant classification standard
