Blower Door System Mdoel GTI650/658

What is Blower Door Testing GTI 650/658?

GTI650/658 is a self-developed, technologically advanced and scientifically designed building air tightness testing equipment. It is mainly used to test the air tightness level of building envelopes, diagnose and demonstrate air infiltration problems, and estimate the natural air permeability and energy efficiency loss caused by air infiltration. It can also be used to evaluate the overall performance of the building, for building energy efficiency, building air tightness testing, reduce energy demand and improve energy efficiency.

International Standards: ASTM E779-03, E1554-07, CGSB-149.10-M86, EN 13829, ATTMA, GBT34010-2017, T/CECS 704-2020.

Why need to do building airtightness testing?

  Building airtightness refers to the ability of a building to prevent air infiltration when it is closed. Building airtightness testing is a method to evaluate the sealing performance of the building's exterior envelope. By detecting and quantitatively measuring air leakage, this test can help identify potential energy waste problems and improve indoor environmental quality.

1. Energy efficiency: reduce heat transfer and optimize air conditioning system operation.

2. Indoor environmental quality: control temperature, humidity and mold growth, reduce noise pollution, and prevent dust and pollutants from entering.

3. Building structure and durability: avoid condensation and damage, wind and waterproof protection.

4. Compliance with regulations and standards: building energy-saving regulations and green building certification requirements.
