Why Altherm ICF?
The Altherm ICF System
Altherm ICF is an award-winning modern construction method designed to address the growing demand for high-quality housing that can be built quickly and at scale.
With the capacity to supply 3,500 homes annually, Altherm ICF offers superior thermal performance, excellent sound insulation, structural durability, and compliance with the latest fire safety standards.
It also offers significant cost savings compared to traditional construction methods, with faster site turnover and lead times of just a couple of days. Altherm ICF is certified by both NSAI Agrément and the BBA and holds ISO 9001 / 14001 / 45001 certifications as a testament to our commitment to quality and continuous improvement.
Our product range is designed to help you build homes that comply with building regulations and meet the new Part L requirements. Our low-energy, compliant ICF products will save you time, reduce costs, and ultimately enable you to build top-quality houses. They are also certified for use in the construction of buildings of up to six stories (18m).
The thermographic diagram below illustrates how ICF assists energy efficient homes.
Using the Altherm ICF range of products, many certified housing projects have been successfully delivered for local authorities and housing bodies, including Cluid, Tuatha, Respond, HSE, IRES, and Urbeo.
How It works, in brief
For a more detailed
breakdown check out
a typical building process using ICF below.
1. Our hollow block wall system is made of flame-retardant expanded polystyrene (EPS). The blocks are comprised of two EPS panels, which are connected by polypropylene webs which provide a core thickness between the EPS panels of either 150mm or 200mm.
The Altherm ICF system will assist you:
Highly efficient building is crucial.
Using our product, a team of approved Altherm ICF installers can erect a pair of semi-detached houses from foundation to apex in approximately 12 days, substantially shortening programme time.
Walls can be built in most weather conditions and logistics is not an issue as our factory is only hours away from any construction site in Ireland.
Controlling build costs is always a significant project concern.
Minimal wastage means Altherm ICF houses are built very competitively, and assembly crews can be easily trained to handle any potential skills shortages.
Altherm ICF meets the highest standards in quality and Part L compliance and contributes significantly to achieving Part L and A ratings for finished houses.
Homes built with Altherm regularly exceed soundproofing standards of >53db and easily surpass air-tightness levels
of 3ac/h.
Safety can never be taken lightly in our industry, and Altherm ICF offers many advantages. It is light and easy to handle and requires only half the number of block layers needed onsite.
And with no heavy machinery needed to move ICF around the site, this also significantly reduces the risk of on-site injury.
2. During construction, the hollow blocks are stacked in rows, and the cavity within is filled with concrete to form
the wall and the load bearing structure of the building.
4. Once the concrete has set, a concrete wall is formed. And this poured wall then retains the Altherm ICF EPS insulation on both sides, delivering further efficiencies.
