Nudura blocks are permanent insulating concrete forms used to create reinforced concrete walls. Manufactured as part of Nudura’s wider ICF system, the range includes different form profiles, concrete-core widths, and insulation configurations for different parts of a building. In practice, selecting the right Nudura blocks comes down to three separate questions: what shape does the […]

A swimming pool shell has to do more than hold water. It must cope with pressure from the water inside, pressure from the surrounding ground, changing conditions when the pool is emptied, and numerous penetrations for fittings and services. ICF blocks for swimming pools provide permanent insulating formwork around a reinforced concrete core. The forms […]
Choosing a wall system on material price alone can give a distorted view of the final build cost. ICF, masonry and framed construction divide structure, insulation, labour and finishing in different ways, so the cheapest individual component does not necessarily produce the cheapest completed wall. So, is ICF construction worth it? It can be when […]
If you are researching the cost of an ICF house, one headline price per square metre is unlikely to tell you what your own project will cost. ICF is a wall construction system, not a separate type of house. A house built using ICF still needs foundations, floors, roofing, windows, heating, ventilation, electrical work, internal […]
An ICF wall is a reinforced concrete wall formed inside permanent insulating formwork. ICF stands for Insulating Concrete Formwork, although Insulated Concrete Forms is also widely used. The forms are stacked to create the wall shape, steel reinforcement is installed where the structural design requires it, and concrete is placed into the cavity. Once the […]
Working out how much concrete is needed for ICF walls starts with two measurements: the wall area and the thickness of the concrete core. For an early estimate, the basic calculation is: Net wall area × concrete core thickness = theoretical concrete volume So, if you have 80 m² of wall and a 150 mm […]
The lifespan of ICF construction cannot be reduced to one guaranteed figure. ICF describes the method used to form reinforced concrete walls, not a separate type of house. Insulating forms are stacked, reinforced where required and filled with concrete. Once the concrete has cured, the forms remain in place as permanent insulation. How long a […]
There is no single price for an ICF block. Different insulated concrete forms cover different wall areas, create different concrete core widths and provide different levels of insulation. For that reason, the most useful figure is usually not the cost of one ICF block. It is the cost per square metre of the specified wall […]
ICF stands for Insulating Concrete Formwork, also commonly called Insulated Concrete Formwork. It is a construction method in which lightweight insulating forms are stacked to create walls, reinforced where required and filled with ready-mixed concrete. The insulated concrete blocks act as permanent shuttering. They hold the wet concrete during construction and remain in place after […]
