Building Doors, Windows & Curtain Walls Testing Equipment can simulate real-world environmental conditions to measure performance.
Airtightness/ Watertightness/ Wind Resistance: A sealed chamber applies controlled air pressure and water spray to the test specimen while measuring air leakage, water penetration, and deformation.
Thermal Insulation: The “hot box-cold box” method places the sample between two temperature-controlled spaces. The heat required to maintain a temperature difference is used to calculate the U-value.
Sound Insulation: Sound is generated in a source room, and the reduction in sound pressure level passing through the specimen is measured in a receiving room.
Mechanical Durability: Robotic arms or actuators automatically open, close, and lock doors/windows repeatedly to test hardware lifespan.
Building Wall Envelope Systems can evaluate wall system performance through steady-state heat transfer and environmental simulation.
Thermal Transmittance (U-value): The guarded hot box method places the wall between hot and cold chambers. The heating power required to maintain a stable temperature difference is measured to calculate thermal resistance.
Weathering & Wind Load Resistance: Specimens undergo accelerated aging cycles (temperature, humidity, UV, water spray). Wind resistance is tested by applying controlled negative pressure to check deformation and failure limits.
Glass Testing Equipment can analyze glass performance using optical spectroscopy, steady-state heat flow, and mechanical impact principles.
Optical & Solar Properties: A spectrophotometer measures transmission, reflection, and absorption across light wavelengths to calculate visible light transmittance and solar heat gain coefficient (SHGC).
Thermal Transmittance (U-value): The guarded hot plate method sandwiches glass between temperature-controlled plates. The heating power required to maintain a temperature gradient determines the U-value.
Dew Point: A cold probe cools the glass surface locally; optical sensors detect condensation to assess seal integrity.
Impact Resistance: A standardized impactor (steel ball or shot bag) is dropped from a specified height to test breakage behavior and safety performance.
Development History of Building Envelope & Fenestration Testing Systems
Foundation & Basic Performance (1950s-1980s)
Early Simple Testing
The start of building envelope testing came from new needs for energy saving and comfort in buildings. After World War II, with many buildings being constructed, simple testing methods began to form.
Doors/Windows Testing: Early tests focused on basic weather protection – simple air and water leakage tests using basic fans and water spray systems, mainly for home windows.
Wall Systems Testing: The 1970s energy crisis pushed the need for heat performance testing. Simple “hot box” devices were made to measure how well walls kept heat in, though methods were not yet standard.
Glass Testing: First equipment could only test basic light passing through glass and simple heat shock tests for early double-pane windows.
This time period saw the creation of first testing standards for air leakage and window performance in America and Europe.
System Development & Standard Setting (1980s-2000s)
Computer Use and Better Testing
The 1980s-1990s brought big changes as computers allowed automatic control and data collection:
Complete Performance Testing: Multi-function testing rooms appeared that could do air, water, and strength tests one after another. The standard “pressure box” became common for window testing worldwide. Testing rules became more similar across countries.
Better Heat Testing: Hot box systems improved with computer-controlled temperature settings, allowing exact measurement of heat transfer for complex walls and curtain walls.
Special Glass Testing: Equipment improved to measure not just light passing through but also solar heat gain and thermal performance as energy rules became stricter.
Important changes included automatic repeat testing for long-term use, early earthquake testing for curtain walls, and connecting these three testing areas into one complete building envelope evaluation.
Green Building & Smart Technology (2000s-Present)
High Performance and Digital Testing
The 21st century’s focus on green building and digital technology changed testing:
Whole Building Science: Equipment now copies extreme weather – hurricane winds, heavy rain, and temperature changes – testing complete wall and window systems together. Testing of full building corners became possible in large testing rooms.
Energy & Environment Testing: Testing expanded to important green building measures:
Better light measurement tools for exact solar heat gain
Full-size daylight and solar heat gain testing rooms
Very accurate heat transfer measurement meeting strict green building standards
Whole building air tightness testing became standard
Digital & Robot Advances: Computer models now guide physical testing. Robot systems do complex long-term use testing (thousands of open/close cycles). Internet-connected sensors provide live data, and results connect directly with building digital models.
Current Integration: Today’s best testing places combine all three areas – testing complete building outer wall systems that include glass, frames, walls, and connections together. This complete approach solves important problems like heat loss at connections, water formation risk, and long-term performance that separate testing could not predict.
Future Direction (Now-2030)
The industry is moving toward:
Live performance watching with built-in sensors
Climate-specific testing for changing weather conditions
Material reuse testing for circular building systems
Smart computer testing that predicts 50-year performance from short-term tests
From separate testing of parts to complete evaluation of building outer walls, testing development has followed – and made possible – building progress toward better performance, stronger buildings, and greener construction.
