ICF Case study:
This two storey detached four bedroom ICF home in Stockton on Tees was taken from inception through to completion. Externally finished in brickwork, from this building appearance not many know of its ICF structure and energy efficiencies this provides its occupants.
Reviewing the proposed location of the building on site, and in discussion with building control, it became apparent that a piling foundation system would be required to form a ring beam.
Roger Bullivant where employed as a subcontractor to undertake the works which included the the percussive fitting of 32 piles. Percussive fitting is in effect the hammering of a steel tube until a level of resistance is achieved by the earth below. The area around the piles is then excavated with cages formed within tied to the top of the piles. Concrete is then poured within the excavation to form a ring beam.
The location of the trees also impacted on the floor choice for this a beam and block floor was selected ensuring cross-flow ventilation.
At first floor level, TGI flooring was then fitted with a weyroc board over. (TGI flooring is an engineered timber floor structure)
The Rhodipor system used was a 300mm wide and this was supplemented with a 50mm cavity and full outer facing of brickwork. The brickwork is tied into the concrete core to ensure stability and is purely for aesthetic purposes.
Heat throughout the property is provided by a gas boiler connected to underfloor heating on the ground floor and radiators to the first.
The initial SAP calculations indicated to an approximate spend of £80.00 (Circa 2004) a year on heating the property which considering the additional insulation in the cavity was money well spent.To date the average fuel spend is still just over this but the heating bills are substantially lower than the neighbours.
