Technical details-Reliable ICF homes

The best possible and most durable insulation

ICF (Insulated Concrete Formwork) buildings have a very high thermal resistance of R-19 (US) as against R1-2 for conventional buildings of concrete, fly ash/ red bricks or AAC Blocks and thus 10-19 times less carbon footprints than conventional structures.


Since the openings like doors and windows are built into the formwork and concrete is poured for a whole floor in one go, there are no air leakages from these perfect plumb openings (provided the door and windows are fitted properly) and air change ratio per hour of 8-9 for conventional buildings under 50 Pascal air pressure can be brought down to 0.5-0.8, thus providing a perfect air tight (15 times better) containment of interior ambience and hence much lower energy consumption in HVAC. The net result is an operating energy consumption for HVAC being up to 80% less.


For the most easily built structures

The concrete cast inside the ICF retains the mix water as well as the heat of hydrogenation from the cement-water reaction, resulting in adiabatic (at constant temperature and pressure) curing of the concrete, and giving you the benefit of practically zero water consumption at site. The ICF blocks being modular and factory shaped to exact sizes, their procurement along with concrete can be planned exactly minimizing site wastage. The lightweight, interlocking ICF blocks make the site creation of formwork for concrete into “child’s play” literally, doubling (could be much more) the overall speed of construction and thereby expenditure on these resources of time and manpower.

The fastest, most durable, and easily perfected method of construction

The perfectly straight walls with perfect geometrical openings and zero thermal bridge floorings and lintels ensure resource conservation in claddings, door-window materials, sealants etc. and contribute to the overall aesthetics of the building for a lifetime as the thermally stable exterior does not undergo the daily cycle of expansion & contraction which leads to thermal stress cracks in the facade and waterproofing layers.
