A Complete Guide to Buying PIR Boards

I. What is PIR?

PIR (Polyisocyanurate) is a third-generation rigid foam insulation material improved upon PUR, possessing a more stable chemical structure and superior fire resistance.

II. Standard Specifications and Dimensions

Effective Width: 950mm, 1000mm, 1150mm

Length: Customizable

Thickness: 50mm, 75mm, 100mm, 150mm

III. Selection Based on Application Scenarios

1.Cold Chain Logistics (Cold Storage, Refrigerated Trucks)

Recommended Parameters:

Density: 40-45 kg/m³

Thickness: 100-200 mm

Surface: Double-sided Aluminum Foil

Fire Resistance: Class B

2.Building Exterior Wall Insulation

Recommended Parameters:

Density: 35-40 kg/m³

Thickness: 50-100 mm

Surface: Single-sided Aluminum Foil + Reinforcing Backing Paper

Compressive Strength: ≥120 kPa

Installation Method: Curtain Wall Internal Insulation/Sandwich Panel Core Material

3.Industrial Plants

Recommended Parameters:

Density: 30-35 kg/m³

Thickness: 75-150 mm mm

Surface: Color steel plate composite

Fire resistance: B1 grade (Cleanrooms require A grade composite board)

4.Special environments

High humidity: Select double-sided aluminum foil, closed-cell rate ≥95%

High vibration: Select high density (≥45 kg/m³), compressive strength ≥200 kPa

High temperature environment: Select heat-resistant type (long-term operating temperature ≤140℃)
