The formwork is filled with concrete and then left permanently in place as thermal insulation.

ICFs provide an alternative method of building walls that competes with 'brick & block' or 'timber frame':

• An ICF is a 'stay-in-place' concrete framework made from EPS and held together with PP or metal webs
• The Forms 'snaplock' together to construct the wall
• The polystyrene panels are installed on site and the cavity is filled with concrete
• The end result is a sturdy envelope with adequate insulation to exceed Building Regulations Requirements

• Waste of heat energy is the single largest contributor to global warming
• Kyoto Climate Agreement demand drastic improvements in building techniques to reduce this
• Almost one half of UK CO2 emissions are caused by the energy consumption of buildings
• ICFs have superior energy performance and have a high mass for thermal stability
• Reduced waste on site
• ICF's are made from recyclable materials
• Low environmental impact

Buildings constructed with ICFs are:

• Stronger
• Cheaper and quicker to construct
• More energy efficient
• Quieter
• More cost effective for the constructor by at least 10%
• Walls can be finished in any material: e.g. brick, render, timber.
• Design flexibility and sustainability
• Ecologically friendly
