Performance Testing for Building Envelope Systems
Our Testing and Mock‑Up services ensure that façade systems, windows, doors, and curtain walls meet the highest standards of performance, safety, and durability.
Comprehensive off‑site Performance Mock‑Up (PMU) testing
We validate system behavior under real‑world environmental and structural conditions before on‑site installation.
All tests are conducted in accordance with international standards (EN, ASTM, ISO), reducing project risk and ensuring full compliance.
Off‑Site Performance Mock‑Up (PMU) Testing
Performance Mock‑Ups replicate real installation conditions and allow early identification of potential design or fabrication issues. PMU testing provides verified performance data and supports informed decision‑making during the design and construction phases.
Air & Water Performance Testing
Air Permeability
Air permeability testing measures air leakage through the system under controlled pressure differences, ensuring:
- improved energy efficiency;
- enhanced indoor comfort;
- reduced heat loss and air infiltration.
Water Tightness – Static Pressure
This test evaluates resistance to water penetration under constant pressure, simulating heavy rainfall and steady wind conditions.
Water Tightness – Dynamic Pressure
Dynamic testing simulates wind‑driven rain and severe weather by applying fluctuating air pressure and water spray to the system.
Hose Test
The hose test is used to detect localized water leakage and verify detailing quality. It is commonly performed:
- prior to project handover;
- during quality inspections;
- for targeted troubleshooting.
Structural Performance Testing
Structural Performance under Design Load (SLS)
Serviceability Limit State (SLS) testing confirms that systems perform correctly under normal operational loads, without permanent deformation or loss of functionality.
Structural Performance under Extreme Design Load (ULS)
Ultimate Limit State (ULS) testing verifies system resistance under extreme conditions such as:
- exceptional wind loads;
- accidental overload scenarios;
- safety‑critical events.
Safety & Resistance Testing
Impact Resistance (Internal & External)
Impact resistance testing assesses the ability of the system to withstand accidental or intentional impacts, making it ideal for:
- public and commercial buildings;
- high‑traffic areas;
- exposed façade applications.
Operating Forces
Operating force tests measure the effort required to open, close, and secure movable elements, ensuring:
- user comfort and safety;
- compliance with ergonomic standards;
- reliable daily operation.
Security & Burglar Resistance Testing
Burglar Resistance – Static Loading
Evaluates resistance to sustained forces applied during attempted forced entry.
Burglar Resistance – Dynamic Loading
Simulates aggressive burglary attempts using repeated impacts to assess system robustness.
Burglar Resistance – Manual Attempts
Tests resistance against forced entry using hand tools, in accordance with recognized international security classifications.
Seismic Performance
Seismic Movement Testing
Seismic testing verifies the system’s ability to accommodate building movements caused by earthquakes while maintaining:
- structural integrity;
- weather tightness;
- operational functionality.
