PIR Insulated Ductwork

PIR Foam Pre-insulated Ductwork

PIR Foam Pre-insulated Ductwork is a top-tier HVAC solution, with a closed-cell polyisocyanurate (PIR) foam core (thermal conductivity ≈0.022 W/m·K) and protective facings (often aluminum). It minimizes energy loss for AC/heating systems, cuts utility costs, and has Class 0/B1 fire resistance (forms a flame-retardant char layer). Lightweight and easy to install, it reduces labor and structural load. Airtight and corrosion-resistant, it works for offices, hospitals, ensuring long-term, efficient performance.

FAQs of PIR Insulated Ductwork

1. What is the fire rating of PIR insulated ductwork?

PIR insulated ductwork often achieves a high fire rating, such as Class 0 under BS 476 Part 6 & 7 standards or Class A under ASTM E84, which indicates its excellent fire resistance properties.

2. Can PIR insulated ductwork be customized?

Yes, PIR insulated ductwork can be customized to meet the specific requirements of any project. This includes customizing the dimensions, thickness, and facing materials of the ductwork to ensure a seamless fit with the existing HVAC infrastructure.

3. What are the key benefits of PIR insulated ductwork?

Superior Thermal Insulation: PIR foam has a low thermal conductivity, typically ranging from 0.018-0.023 W/m·K, which helps to minimize heat transfer and improve energy efficiency.

Fire Safety: PIR foam is inherently fire-resistant, often meeting stringent fire safety standards, which enhances the overall safety of the building.

Durability: PIR insulated ductwork is lightweight yet durable, with a long service life and resistance to moisture, corrosion, and mold growth.

Sound Absorption: The dense structure of PIR foam helps to dampen sound, reducing noise levels in HVAC systems.

4. Is PIR insulated ductwork environmentally friendly?

Yes, PIR insulated ductwork is considered environmentally friendly. It does not contain CFCs and HCFCs, formaldehyde, or free benzene, which are harmful substances banned in many countries. Additionally, PIR foam has a low global warming potential (GWP) and ozone depletion potential (ODP), making it a sustainable choice for HVAC systems.

5. How does PIR insulated ductwork compare in cost to other types of insulated ductwork?

PIR insulated ductwork may have a higher initial cost compared to some traditional steel insulated ductwork materials, such as fiberglass or mineral wool. However, its superior thermal insulation, fire safety, and durability properties can lead to long-term energy savings and reduced maintenance costs. Therefore, when considering the total cost of ownership, PIR insulated ductwork often proves to be a cost-effective choice.
