Specialist areas

Bending, tensile and pressure tests

Schüco has a tradition of carrying out its own component and material tests. Testing began in 1967, and in 1968 the first second-hand universal test machine was acquired from TU Berlin. Today, in addition to static and dynamic pressure, bending and tensile tests, the mechanical performance of thermally broken outer and vent frame profiles is also tested. The tests are carried out at room temperature and between -20°C and +80°C in a self-contained measuring room. The ageing of test specimens under defined variations in weight and temperature is also tested over a period of up to 1000 hours.

Tests for which no standards exist can also be carried out. For example, these are to work out the test values for the structural calculation of joints. These are calculated in agreement with the client, not just for components and materials, but often also for environmental simulations, and also in the other test areas of the Technology Center, if required.

Environmental simulation

A close eye on every climate

When reliable statements on climate issues relating to the building envelope are needed, environmental simulation tests are absolutely essential. The same is true for information regarding the ageing behaviour of materials, surface finishes and products due to heat, cold, humidity, UV light and corrosive media. The Schüco Technology Center has a wide variety of options available to achieve this.

The differential climate chamber for components and complete units up to a size of 3000 x 3000 mm is completely new. Differences in temperature and humidity between the inside and outside are simulated in the special construction made for Schüco. It even allows bulky components to be tested under all humidity conditions.


  Safe electronics and a high level of building protection  

All Schüco products fitted with the company's own electronic components or non-Schüco products must have proof of their electromagnetic compatibility. This requires the interference immunity and interference emissions of the components to be tested in line with the standards. It ensures that there are no malfunctions and no harmful electromagnetic waves are emitted. At the same time, protection rating tests verify whether components are sufficiently resistant to environmental factors, such as dust and water, or whether hazardous and live components are adequately fused. This is how Schüco is reacting to the sharp increase in electrically operated, controlled and energy-generating façades, windows and doors. All the tests are already carried out at an early stage during development, but also on projects that are already complete.

To adhere to the requirements of the EMC directive, different tests of the conducted interference are possible by means of exact simulation in a new shielded chamber. The purpose of the tests is to improve Schüco products or non-Schüco parts in order to meet EMC requirements.

Bullet proof

Protection from bullets

On the new ballistics test rig, test samples are shot at using various projectiles from different angles and distances of up to 25 m. If the result is positive in terms of the standard, this results in classification into one of the bullet resistance classes FB1 to FB7. They apply to all bullet-resistant units which can be fabricated from Schüco window, door and façade systems. This ensures that when a shot is fired, the projectile does not penetrate the interior, nor does the material or glass splinter on the inside of the test specimen. Schüco performs a preliminary test that conforms to standards in conjunction with its own ballistics tests. To do this, the bullet speed must also be accurately measured. For a full metal jacket spitzer bullet, this is up to 810 m/s, which is almost three times the speed of sound.

Tests conform to DIN EN 1522, Feb. 99 / 1523, Feb. 99. If the result complies with the test standard, the official test is carried out at the ballistics office in Ulm. There is a new test rig for pendulum impact and burglar resistance tests.


Sound insulation of the original component

The reliable sound insulation of a façade can only function if noise transmission is prevented by the external façade. Schüco is not only able to test this on original components in the Technology Center, but also find out the causes of any defects in order to subsequently improve the component. This is particularly important for the sound reduction of systems which can be used flexibly to partition rooms in office buildings. For even once interior rooms have been converted, confidentiality should be guaranteed by means of sound reduction, particularly in sensitive areas. For realistic measurements in the area of building acoustics, four rooms which are independent of one another are available, which are also acoustically insulated from vibrations in the rest of the Technology Center. Schüco provides building consultants, metal fabricators and architects with advice on complex issues relating to building acoustics. Schüco also takes measurements on site to ensure the fabrication and installation quality, or for the acoustic separation from other trades. There are also joint tests for special solutions in terms of feasible acoustic requirements.

This is where system tests are carried out for window and room partitioning systems, as well as for complete façade units measuring 2.8 x 3 m. The airborne sound insulation against external noise is measured, as is the flanking insulation for noise transmission in interior rooms or between floors.

Samples workshop

In the Schüco samples workshop, all types of samples and test units are fabricated, just like in an independent metal fabrication company. To do this, by extending from 700 to a good 2000 m2, there is now a CNC-controlled profile processing centre and a double-headed mitre saw available, as well as plenty of space for new machinery. All new systems are built in the samples workshop for the first time so that they can be subsequently tested. The workshop is therefore the "First Schüco metal fabricator". The samples workshop is not only more diversified as a result of the reconstruction, allowing it to process a wide variety of profiles and systems in parallel, but it is also able to produce more prototypes.

Watertightness tests

Hurricanes don't stand a chance

In the Technology Center, Schüco has the largest indoor façade test rig in Europe. In the newly built 18 m high hall, joined façade units up to 21 m in width and 13 m in height can be tested. This allows Schüco to test larger and more complex constructions than ever before in a realistic way. The extension is a big step towards meeting the growing demands of customers in the long term. In addition to information on the fabrication and installation quality, these tests allow the construction quality of special solutions to be assessed at an early stage. Additional tasks performed by Schüco include error analyses and a wide variety of consultancy services.

Weathertightness testing, from individual components through to complete façade units, includes watertightness, air permeability and wind load tests. For façade tests, the dynamic wind load is tested, whereby in addition to draining rainwater, a strong, turbulent stream of air from outside is built up. Seals are also tested by simulating ceiling movements, or safety barriers in the event of the entire building moving.

Mechanics, lifecycle and safety

Focus on quality and safety

A key issue for the Schüco Technology Center is the area of mechanics, durability and safety. This is where windows and doors, blinds, opening devices, cavity-fitted gearboxes or electric drives are subject to durability testing. The functionality of cable link connectors for electrically operated windows and doors is also carefully examined here. Type testing can also be carried out for fire and smoke protection. The test rig for pendulum impact tests on windows, doors, façade units and photovoltaic modules is new and can also be used for static and dynamic burglar resistance tests. Durability tests on complete fittings are carried out using high-performance robots. In radiant heat tests on components and profiles up to 80°C, their deformation and the influence this has on their functionality is calculated. The utmost confidentiality is ensured by the physical separation from other departments.
