Thermal Resistance Rigid Insulation Board 70mm PIR

The Aluminum Foil 70mm PIR Insulation Bords is a top-tier rigid thermal insulation board, constructed with a high-density PIR(PIR – short for polyisocyanurate) foam core and laminated on both sides with reflective 0.08mm aluminum foil. This PIR 绝热板 insulation board offers exceptional thermal resistance, dimensional stability, and moisture protection—making it an ideal solution for building envelope systems, and energy-efficient wall and roof assemblies.

Why PIR Rigid Foam Board Insulation Is the Smarter Option

This 70mm PIR insulation rigid board combines structural integrity with superior energy efficiency. With thermal conductivity as low as 0.02 W/m·K, the PIR rigid insulation board significantly reduces heat gain and loss, supporting thermal regulation in all climates.

Its aluminum foil facings enhance thermal reflectivity, block moisture ingress, and provide added fire performance. This product is widely used in green building designs where high R-value and reduced material thickness are required for optimal energy savings and space efficiency.

Typical Applications of 70mm PIR Rigid Thermal Insulation Boards

1. Wall Insulation Systems

外墙外保温复合系统（ETICS）: Our PIR rigid insulation boards are commonly used as the main thermal layer in external insulation systems. Installed under cladding, render, or ventilated façades, they reduce heat transfer and enhance building energy performance.
Internal Wall Insulation: PIR rigid foam insulation boards are also ideal for interior retrofits. They offer high thermal resistance while maintaining minimal thickness, making them perfect for improving older buildings without altering the exterior.

2. Roof Insulation (Flat & Pitched)

Flat Roof Insulation: Applied directly above roof decks, these rigid thermal insulation boards form a continuous layer, limiting heat loss and withstanding long-term compression.
Pitched Roof Insulation: Whether between or over rafters, our 70 mm PIR insulation rigid boards are easy to install and provide high R-value thermal protection for sloped roofing structures.

3. Floor Insulation Applications

Underfloor Heating Systems: The 70mm PIR insulation board delivers excellent downward heat resistance in radiant floor heating systems, helping optimize heat distribution and reduce energy waste.
General Floor Insulation: Suitable for suspended timber floors and slab-on-grade construction, these boards improve thermal comfort while supporting load-bearing needs.

4. Curtain Wall Insulation

PU and PIR rigid insulation boards can be integrated into modern glass curtain wall systems to boost thermal efficiency. Installed as part of the cavity structure, they reduce overall U-values without compromising design aesthetics.

Is PIR Insulation Flammable?

The following pictures show the state of the RLB-l PIR Insulation fireproof composite board under the direct combustion of the 1300℃ flame torch for each period of time. During the entire experiment, the RLB-I PIR Insulation Board did not burn through and did not drip water. Preventing flame spread and heat conduction, no burning phenomenon.
