Discover why 40–50kg/m³ is the optimal density for PIR foam insulation board. Learn how proper density maximizes thermal performance and structural integrity.
GFI PIR Foam Insulation Board offers excellent thermal insulation, fire resistance, and long-lasting durability. Ideal for walls and roofs in commercial and residential buildings.
phenolic pre-insulated ducts combine thermal insulation with durability and fire resistance. This guide covers the entire fabrication process, including layout, cutting, forming, reinforcement, connection, and installation, ensuring high-quality and efficient HVAC ductwork.
The TJ Commercial Plaza (180,000㎡) integrated a 30,000㎡ PIR Foam Duct System, replacing traditional galvanized steel ducts. This transition achieved 40% cost savings per square meter and cut installation time by one-third.
The Overlooked Choice of Exterior Wall Insulation Materials In many construction projects, Exterior Wall Insulation Board materials tend to be limited in variety. This is often due to insufficient consideration by contractors, who typically select Insulation Materials based on short-term cost control rather than long-term performance and economic benefits. As a result, the selection of […]
1.Importance of Duct Airtightness Duct airtightness plays a crucial role in HVAC (Heating, Ventilation, and Air Conditioning) system efficiency, air quality, and energy consumption. When it comes to duct testing, airtightness is the ultimate challenge—materials, connections, workmanship, testing conditions, and equipment accuracy all matter. The details make or break the results. Project acceptance is like […]
