THE OCCUPIER AND ICF
Low Running Costs – ICF structures offer low ‘U’ Values from 0.30W/m²K down to 0.10W/m²K. Dense concrete is the structural core with layers of insulation ensuring “thermal mass” benefits are obtained which means that the building is warm inside when it is cold out-doors in winter and vice versa in summer.
Good Acoustic Performance – Due to the density and thickness of the concrete cores within the ICF, excellent acoustic insulation is provided.
Healthy Indoor Environment – An ICF building will have minimal air leakage as it is a monolithic structure. Studies have shown that occupants with allergies and chest complaints will have minimal difficulties caused by dust and pollen within the property.
Fire Resistance – All Insulated Concrete Formworks provide fire protection in excess of normal requirements. EPS (expanded polystyrene) is manufactured containing a fire retardant substance, which means the ICF does not support a flame.
Minimal Flood Damage – Concrete and construction grade EPS are unaffected by water. If ICF buildings are in an area which is subject to possible floods, they will withstand the pressure of water and flood damage will be minimised. ICF properties exposed to water can be pumped and dried out leaving the structure integrity unaffected.
ROT and Vermin – ICF structures do not rot and are unaffected by vermin and termites.
Wind, Storm & Earthquake – Since ICF systems are concrete framed structures, they can be designed to the relevant codes for earthquake zones and provide successful protection from heavy storms and high winds including hurricanes and tornadoes.
Mortgage, Insurance and Planning Acceptance – ICF structures, as a concrete framed building, are accepted by all reputable companies and organisations providing they have passed the recognised third party tests and standards that are needed to obtain building approval. In the UK ICF suppliers should have either BRE or BBA certification and ready-mixed concrete should be supplied from manufacturers offering BSI or QSRMC Quality Assurance schemes.
Easily Adapted for Future Needs – Because concrete frames offer a whole floor space without further loadbearing walls, it is easy to remodel and upgrade floor layouts in the future. The strength of the ICF walls allows extra floors to be added, subject to authority approval, and it is easy to add and tie in future extensions. The structural walls will also accommodate extra openings in the future if needed. Should even lower U values be required in the future, extra polystyrene could be fitted externally and re-clad.
Minimal Maintenance Required – Under normal circumstances no maintenance would be required on the ICF walls in the life of the building. The internal and external facades could be subject to minor damage which could be easily repaired or completely stripped and renewed.
Insulating Concrete Formwork has many benefits over traditional building methods
