An amazing self-build property built on a JACKODUR® ATLAS foundation slab has won the Small Project Category of the 2021 Passivhaus Awards.
The property, Larch Corner, is located in Warwickshire and predominantly features modern timber engineering in its above ground construction. However, the building is based on JACKODUR® ATLAS foundation system from JACKON.
The JACKODUR® ATLAS Extruded Polystyrene (XPS) insulation and formwork system is an intelligent and efficient thermal insulation system for floor slabs and is ideal for constructing the foundations of energy-efficient houses.
The system comprises an economic interlocking system, which eliminates thermal bridges and has excellent compressive strength properties. Supplied cut to size, rapid and problem-free construction is assured.
In this particular property the floor has a U-value of 0.101 W/m2K and the building overall is claimed to be the most airtight house in the UK and the third most airtight house in the world, exceeding current building regulations 244 times over!
Thanks to the elimination of heat loss through the floor of the structure, JACKODUR® ATLAS plays a critical role in helping Larch Corner achieve its net zero credentials. The owner and builder says that he was able to turn off the heating system in the house, provided by an air source heat pump and photovoltaic array, in March and hasn’t needed to use it since.
JACKON’S expertise in the creation of building materials for low energy buildings goes far beyond the manufacture of foundation systems. The company has over 60 years’ expertise in manufacturing both XPS and Expanded Polystyrene (EPS). While JACKODUR® ATLAS uses XPS, the company’s THERMOMUR® Insulating Concrete Formwork (ICF) EPS system can be used in combination with it, to create highly energy efficient buildings.
