Eliminate the Critical Wall-to-Floor Cold Bridge

KORE's Insulated Foundation System helps to eliminate the critical wall-to-floor cold bridge (thermal bridge) normally found when building a traditional raft foundation. The Passive Foundation uses expanded polystyrene (EPS) to wrap the junction in a continuous layer of insulation, ensuring the wall-to-floor thermal bridge is eliminated and there is no break in insulation between the non-insulating materials.

It is important to note that other repeating, non-repeating and random thermal bridges be eliminated or reduced with proper planning and design, as increased levels of insulation can make heat loss worse at other cold bridges. Examples include the wall-to-roof junction and openings within the building's thermal envelope, such as windows, doors and reveals.

Achieve Low Floor U-Values

Building Regulations in Ireland (Part L - Conservation of Fuel and Energy - Dwellings 2011) define the U-values that must be achieved when building a new home:

  • Floors with No Underfloor Heating: 0.21W/m2K 
  • Floors with Underfloor Heating: 0.15W/m2K

KORE's Passive Foundation System can achieve U-values much lower than those required by Part L, ranging from 0.08W/m2K to 0.10W/m2K, depending on the construction type.

Improve the Performance of Underfloor Heating Systems

The Passive Foundation System drastically improves the performance of underfloor heating systems. Studies have shown that up to 65% of heat generated from underfloor heating systems can be lost through rising walls. Thanks to the elimination of the wall-to-floor thermal bridge, this number can be reduced to as little as 12% by using a passive foundation. Not only will this help keep the home more comfortable, but occupants should notice a decrease in energy usage and related costs.

Suitable for All Ground Conditions and Construction Types

KORE's Passive Foundation is suitable for all ground conditions and construction types. This includes cavity wall construction, timber frame, insulated concrete formwork (ICF) and solid block walls. Most applications utilise KORE Passive Foundation EPS300 White and KORE Floor EPS100 White material. Bearing capacities of soils and sample U-value calculations can be found in the Passive Foundation Design Guide and within the technical data by signing up for the KORE Resource Centre. You can also contact our technical team to discuss your individual project requirements.

Fully Engineered

The KORE Passive Foundation is fully engineered to your project's specifications. Our technical team will complete the foundation load calculations, design certificates for foundation and the foundation plans showing ringbeams, thickenings and sectional details through the principle elements of the foundation, such as the reinforcement required. If you already have an engineer on-site the Passive Foundation can be designed and manufactured to their specifications. We're here to make the process as easy as possible depending on your individual time and resources.

Built to Last

Like all of our EPS products, the Passive Foundation is built to last the lifetime of the building. The thermal performance of KORE EPS will not diminish over time, is water resistant, and eliminates the possibility of condensation, fungus and mould growth, especially behind the skirting board. EPS is sustainable, meaning it can be recycled and reused once the lifetime of the building has been reached and is maintnance free.

Comparable in Price to a Traditional Strip Foundation

You shouldn't have to sacrifice comfort for money, and that's why we've developed a system that is comparable in price to a traditional foundation system. The overall cost of a passive foundation is the same, and sometimes less, when compared to tradiditional foundations being used in the UK and Ireland. Installation of the Passive Foundation usually takes less time and requires up to 50% less concrete - meaning costs associated with labour and materials is reduced.
