Sunbloc is the latest and most advanced insulated concrete formwork system. Designed and manufactured in the UK to meet the specific needs of the industry from simple extensions through to commercial builds up to five stories.

Our design team with over twenty years experience of building with various ICF systems carried out worldwide research into the respective merits of the many systems on offer. They identified over 30 essential design features for inclusion into a comprehensive and simple Sunbloc package. No other ICF system incorporates all these design concepts within a single element. Some - such as the vertical interlock and the patented dowel are indeed unique to Sunbloc.


Every detail from our trestle support through to our V-Tec floor system has been examined to ensure a successful build. The vertical interlock and staggered web/spacer arrangement provides a formwork of exceptional strength.


Sunbloc is the first ICF in the world to use Multifoils to improve the thermal emissivity of the wall structure. This permits narrower wall construction and at lower unit cost. Manufactured from Neopor a highly insulating form of EPS recently developed by BASF, Sunbloc offers the highest levels of thermal performance at the lowest space premium.
