Rigid board insulation consists of stiff panels (PIR, PUR, XPS, EPS, or mineral wool) that deliver strong, continuous thermal protection.
How it works:
The boards trap air or gas within their structure, slowing heat transfer and maintaining consistent insulation across surfaces.
Applications:
- Exterior walls – continuous insulation behind cladding
- Roofs – flat or low-slope systems, over purlins, ceilings
- Foundations & basements – below-grade, moisture-resistant insulation
- Floors & slabs – beneath concrete to prevent ground heat loss
Benefits:
- High thermal resistance (R-value) per thickness
- Durable with excellent compressive strength
- Resists moisture (especially XPS, PIR)
- Reduces thermal bridging and air leakage
- Improves energy efficiency and comfort
