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, it is suitable for most types of build from simple extensions through to commercial builds up to five floors.

Unique Design
Our design team with over ten 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.

Some typical examples:

Green Issues
As demonstrated by the above illustration, Sunbloc will attain the Code 6 level for Sustainable Homes. Passive House standards can be reached with a total wall thickness of just 33cm. When filled with sustainable concrete Sunbloc achieves an A+ Green Guide rating

Simplicity of Build
4-way reversible Sunbloc is the latest and most simple ICF system to build with. A short corner block is included in the range whilst the need for left and right hand corners together with the T junction elements has been eliminated. Plastic Webs provide for ease of cutting and positioning of steel work. Importantly, on completion of the build the modular dimensions and reverse capability designed into Sunbloc, ensure wastage is minimal and can be limited to site disposal – see LABC registered details.
All deliveries are supported by our fully trained installers.

Basements and Pools
Uniquely our webs are moulded with a series of water bars to prevent tracking of water across the spacer. Sunbloc ICF provides the most cost effective method of building water tight structures both above and below ground. A water ingress warrantee is available.

Curved Walls Etc
Curved walls, Bays and other non linear features are readily formed by making use of the integrated dowel, moulded into each and every web at 150 mm spacing.

This dowel will also accommodate errors or last minute changes to the modular design. It provides an affective method of joining or “stitching” together elements in a vertical plain.
