Here’s what sets it apart:

Certified to the latest 2024 Building Regulations - ensuring full compliance with the most up-to-date structural, fire, thermal and safety standards.

Exclusive fire-safety clarification for attic spaces - No plasterboard or apex treatment required when using the Altherm fire-strip configuration (Altherm only provision).

Updated concrete strength specification - for enhanced structural performance.

Increased range of external finishes - approved for use on our system.

Extended detailing across drawings - giving design teams deeper clarity and confidence.

Our new Altherm ICF block now achieving U-Values as low as 0.15 W/m²K - supporting the industry’s push towards near-zero energy performance.

This certificate confirms Altherm ICF as one of the most rigorously assessed and              future-compliant ICF systems on the Irish market.

And a huge credit to the NSAI for their diligence and dedication — their work continues to strengthen quality, safety and innovation within the Irish construction sector.
