PIR Pre-insulated Ducting Board
PIR (polyisocyanurate) pre-insulated duct board is a composite panel that serves as both the structural duct and its thermal insulation in one product, making it an efficient alternative to traditional metal ductwork for HVAC systems.

Key Features and Benefits of PIR Pre-insulated Ducting Board for Contractors
Here are the primary advantages this system brings to your projects:
Excellent Thermal Performance:
With a thermal conductivity around 0.02 W/m·K, the PIR core provides superior insulation that minimizes energy loss. This can contribute to lower lifecycle costs for building owners compared to poorly insulated metal ducts.
High Fire Safety:
The material is inherently fire-resistant. Many products meet the stringent 'Class 0' fire rating standard (BS 476 Part 6&7) and are formulated without CFCs or HCFCs, making them an environmentally responsible choice.
Lightweight and Durable:
PIR duct boards are significantly lighter than galvanized iron ductwork, reducing the load on building structures and making them easier to handle on-site. Despite being lightweight, they are robust, with a density around 50 kg/m³ and high compressive strength.
Faster Installation:
This is a key selling point for contractors. The system requires a "single fix installation process", which can dramatically speed up project timelines compared to the multi-step process of fabricating and insulating metal ducts.
Long Service Life:
The PIR foam core is closed-cell, which gives it very low water absorption (as low as 0.36%). This, combined with corrosion-resistant facings, contributes to a long service life of over 20 years and low maintenance costs.
