🚨 Important Update from Altherm ICF 🚨

We’re proud to announce that the new Altherm ICF Agrément Certificate is now live — and it reflects some major advancements for our system and for anyone building with ICF in Ireland.

Here are the key updates:

✅ Fully aligned with the 2024 Building Regulations
Our certification is now based on the latest standards, ensuring full compliance and future-proof construction.

✅ Clarification on attic fire treatment
No plasterboard or treatment is required at the apex within attic spaces thanks to the placement of the Altherm fire strip.
This detail is unique to the Altherm ICF Agrément Certificate.

✅ Updated concrete strength requirement

✅ Expanded options for external finishes
More flexibility for designers, builders, and homeowners.

✅ Enhanced detailing across all drawings
Clearer, more comprehensive information for smoother builds.

✅ Launch of our new Altherm ICF block
Designed to achieve U-values as low as 0.15, supporting even higher performance homes.

These updates underline our ongoing commitment to delivering the highest-quality ICF system on the market, backed by rigorous testing and certification.

Altherm ICF — Leading the way in energy-efficient, regulation-ready construction.

Rathangan Site Update ❄️

There’s a hard frost settling over Rathangan this morning. The ground is white, the air is sharp, and temperatures are far too low for a concrete pour – but that doesn’t slow us down.

One of the major advantages of the Altherm ICF system is the ability to continue erecting walls in all weather conditions, regardless of the time of year. Whether it’s frost, snow, rain, wind, sleet, hail, heat or humidity, our installation process remains efficient, controlled and safe.

Even when pours must temporarily pause due to freezing temperatures, the team can continue assembling the walls, placing reinforcement, preparing levels and working ahead for the next stage. This means productivity stays high and downtime is kept to a minimum.

With traditional building methods, winter can bring the site to a standstill.
With Altherm ICF, the structure keeps rising, the build keeps progressing, and momentum stays strong throughout the colder months.

Reduced delays, predictable scheduling, enhanced thermal performance, and a more reliable build programme – that’s the value of ICF.

Another solid day on site in Rathangan, despite the frost.

Enhancing Soundproofing with Altherm ICF Party Walls

At Altherm ICF, we understand the importance of comfort, privacy, and performance within every home. Our ICF party wall construction offers outstanding acoustic separation, creating quieter, more comfortable living spaces in semi-detached and terraced dwellings.

Our system delivers enhanced sound resistance due to the combination:
• A robust 150mm solid concrete core, proven to provide exceptional mass and reduce airborne sound transfer
• High-density EPS insulation, providing additional sound dampening
• Continuous, airtight construction, eliminating gaps and weak points
• Engineered detailing at junctions, ensuring full compliance with acoustic standards

With the Altherm ICF 150mm concrete core combined with standard plasterboard, our system has been proven to easily exceed the required sound performance regulations for party walls, ensuring superior acoustic separation and long-term comfort.

When built in accordance with engineers’ design, Altherm ICF party walls help ensure that each home maintains exceptional soundproofing performance throughout its lifetime.

Whether you're a homeowner, developer, or contractor, our ICF system provides reliability, durability, and consistent results on every project.

If you’d like guidance on acoustic detailing or want to learn more about our party wall solutions, feel free to reach out to our team.
