expanded polystyrene which then completely encases the furring strips 12 only the openings of the tubes 12 1 are visible after the moulding is completed as shown in fig6 the furring strip 12 is embedded so that the flat side of the bar 12 3 is about u00bd u2033 from the outside wall of the panel 22 since the steel connector 14 is engaged with the plastic tube 12 1 which only has minimal thermal conductivity and the bar 12 3 is located u00bd u2033 away from the outside wall of the panel 22 a full thermal break is obtained therefore the conductivity of heat or cold through a wall constructed with the insulated concrete forms 20 is effectively counteracted after moulding the panels 22 are joined together by the connectors 14 which are inserted into the diamond shaped tubes 12 1 as described above the form 20 can therefore easily be assembled either on or off the job site which allows for larger shipments of the form 20 saving delivery costs the connection of the connectors 14 may also be effected while the panels 22 are still warm after ejection from the mould the strip 12 is manufactured extruded in continuous form and is then cut into the required length depending on the depth of the form 20 that is being made as shown the form 20 is provided with tongue 20 1 and groove 20 2 formations for easy placement of adjacent forms 20 in use the forms 20 are placed on the foundation of a building being constructed steel reinforcing bars are placed in the forms 20 and the forms 20 are then filled with concrete the web 10 provides for faster flow of the concrete because it does not form an obstruction.
