Polystyrene ICFs vs Nexcem
How do we compare to other insulated concrete forms?
There are so many reasons why Nexcem insulated forms are better than other polystyrene ICFs and we will try to highlight the main advantages below:
Environmental Considerations
– No polystyrene, foams or plastics. No VOCs or off gassing
– 100% recycled wood content; We only use recycled waste wood (100% clean, natural softwood lumber)
– Negative Carbon Footprint; because of the carbon sequestered in the wood
Performance Considerations of Nexcem vs Polystyrene ICFs
– Does not burn or melt. 4 hour fire rating, zero flame spread, smoke spread of 11 and no black smoke or toxic fumes created in the event of a fire.
– More energy efficient. Insulation inserts are positioned towards the exterior, where it should be, to maximize any thermal mass gains.
– Impact resistant. Will not dent. Polystyrene ICF substrates result in stucco and drywall finishes that can easily be damaged through regular use.
– Termite proof. We have completed a 7 year termite study with US Forest Service and found no damage to the Nexcem material over this period of time.
– Breathable (Vapour permeable). Inhibits mold growth
Construction Considerations
– Stronger. We have zero blow-outs in the field when poured in accordance with our recommendations.
– Less Bracing. Nexcem walls don’t bow and bend as easily as the foam blocks
– No Voids. Because the Nexcem is a porous free draining material, it doesn’t allow for trapped air when pouring.
