British manufactured Durisol blocks are the simple and sustainable alternative to brick, block, and timber-frame construction. Whether you are a self-builder, a professional property developer or a social housing provider our products offer an easy, cost-effective and thermally efficient way to build.

Building with Durisol Insulated Concrete Form (ICF) can save up to 30% compared to the cost of traditional brick and block masonry.

Durisol is the original ICF. The units were introduced to the UK in 2005 having been successfully used in build projects across mainland Europe for over 70 years.

How it works

Our ICF wall form units are quick and easy to construct. The pre-insulated interlocking blocks are dry stacked together to form the walls. They are then in-filled with concrete to form a monolithic structural walling system. Unlike other ICFs, there is no need to prop the walls during construction as the weight of the units holds them in place.

All of our wall form units are manufactured in South Wales from recycled cement-bonded wood fibre material.

Suitable for a Wide Variety of Builds

Durisol ICF wall form units can be used for a wide variety of builds from simple home extensions, one-off new builds and basement projects through to housing developments and commercial buildings. Take a look at some of our featured projects.

The Durisol units are thermally insulating, non-combustible, durable and sound absorptive. The simple construction method makes them quick to construct and offers an attractive build solution for self-builders.
