What is ICF?

ICF Insulated Concrete Forms come in a variety of materials and sizes.


The principal idea is the same for all types, they act as a mould for the concrete to be poured to create the structure of the building but also include the insulating layers all in one.  The idea of ICF is not as new as people think, It started just after World War II where new construction methods were needed to meet the demand after the bombings.

Since then the ICF principle travelled to north America where they primarily use it in basements and hurricane areas. In the 70s the first ICF houses appeared in the UK, and now with building regulations getting stricter the ICF method of build is becoming more and more common due to their efficiency.

Aled Wilcox has previously been awarded, for two years in a row, Best New Home Builder & Renovator – Wales, at the 2017 and 2018 Home Builder Awards. Research was carried out by our team of 8 highly experienced industry professionals, and the decision making process handled by our dedicated in-house judging panel took over 320 man-hours, during which time each team worked closely to ensure that only the most deserving firms, departments and individuals were recognized.

Case Study: Malvern Hills

Our biggest most complicated job to date was in the Malvern Hills.

Owners John and Gill Flewers returned from New Zealand following work opportunities, and with aspirations to build their dream home back in the UK. Having considered a number of different plans and builders, due to the structural complexity of the build, ICF proved to be the best option by far. With insulation designed to maintain minimum heat loss and taping for airtightness, ICF had many advantages over other build methods.

On this project we were contracted to install the ICF walls, intermediate floors and roof joists. The Flewers were happy with the progress of the build and we were asked to continue until competition. The ICF system was used in the construction of retaining walls – the large openings could be made in one pour without the need for a large steel frame, as would be required with other build methods.
