Everything you need to know about our ICF products and system
Our products can help you
Optimum air-tightness and soundproofing is easily achieved with Altherm ICF while our proprietary cavity closers can eliminate cold bridging around window and door openings. In an era of carbon footprints and consumer energy awareness, house buyers are always looking to decrease energy usage and spend less on fuel.
How it works, in brief
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.
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.
Around openings like doors or windows, the cavity is formed by fitting our unique Altherm ICF cavity closers. Significantly decreases thermal bridging levels.
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.
