How does it perform better?

ICF Structures built with NUDURA provide a range of benefits in strength, comfort, energy efficiency and fire resistance.

Energy efficiency

NUDURA structures have a continuous layer of inner and outer insulation which dramatically reduces cooling losses and air infiltration. The result is significantly improved energy performance, with cooling load reductions of up to 70% possible. This results in numerous benfits including smaller AC requirements, a more comfortable space, and an environmentally friendly building.


The high quality building envelope of an ICF house ensures an even temperature within the buildings, reducing cold spots and optimising energy perfromance. The highly insulated building elimates the need to overcool the building space, resulting in a stable and comfortable temperature throughout the day and night. Inhabitants of ICF buildings consistenly report being more than satisfied with the internal comfort levels.


The solid concrete core of a NUDURA ICF structures provide greater strength and impact resistance than a building constucted using concrete blockwork. The structure is made of a continous piece of reinforced conrete which provides incredible strength.

Service Life

Insulated concrete forming products allow a building to stay in service longer with reduced maintenance costs compared to traditional construction. Buildings that have to be torn down after 50 years because the materials used in the first place were chosen on a cost basis, or on short term benefits, ultimately, have greater consequences on the environment

Fire resistance

The solid reinforced concrete core ensures that NUDURA structures offer maximum safety with a fire protection rating of up to 4 hours. The forms are made from a non toxic fire retardant expanded polystyrene foam ensuring maximum safety.

Acoustic Performance

NUDURA ICF Structures act as an effective sound barrier, filtering out unwanted noise, dampening sound vibrations from unwanted outside noise creating comfortable working or living spaces for occupants. NUDURA icf structures create the ultimate in building comfort.
