Thermal insulation ALPHACORE PAD

mineralpanelexterior

Overview
AlphaCore Pad is a microporous silica-based insulation panel featuring a water-repellent core. It delivers a thin-profile thermal and fire-performance solution for applications where limited construction depth is critical, such as rainscreen façades and structural soffits. Euroclass: A2-s1,d0. Thermal conductivity (lambda): 0.020 W/mK.

Product Highlights

• Euroclass A2-s1,d0
• Microporous silica-based insulation for premium thermal performance
• Thermal conductivity (lambda) 0.020 W/mK
• Water-repellent core (Wlp ≤ 0.95 kg/m², EN 12087:2013)
• Optimised for new build and refurbishment projects
• Slim solution for rainscreen façades and structural ceilings (soffits)

Applications & Compatibility
Designed for rainscreen systems and structural soffits where minimal insulation thickness is required. AlphaCore Pad can be layered with other Kingspan products (for example K-Roc Rainscreen Slab) to achieve target U-values while minimising overall construction depth. Suited to projects where projections or close boundaries restrict available depth.

Frequently Asked Questions

• What is the U-value of Kingspan insulation? The product does not have a standalone U-value. U-values are calculated for complete building assemblies as the inverse of the sum of thermal resistances of all layers. Perform a U-value calculation for the specific assembly in which AlphaCore Pad will be used.
• Can AlphaCore be fitted with K-Roc Rainscreen Slab? Yes. AlphaCore Pad and K-Roc Rainscreen Slab can be combined in rainscreen systems; layering allows meeting U-value requirements with a slimmer construction depth.
• What is the Euroclass system? Euroclass (EN 13501-1) classifies reaction-to-fire performance from A1 (non-combustible) to F, with additional smoke (s1–s3) and flaming droplet (d0–d2) criteria.
• Is AlphaCore Pad water-repellent? Yes. The microporous silica core is water-repellent and achieves long-term partial immersion absorption Wlp ≤ 0.95 kg/m² (tested to EN 12087:2013).
