How We Build

Insulated Concrete Forms (ICF)

Insulated Concrete Forms (ICF) are becoming a more common way to build homes. This innovative building material is typically made of blocks of polystyrene foam with space in between to pour a concrete wall.

ICFs are found mainly in new construction rather than retrofitting projects. They are easy to install and have several advantages, including strength, durability, and the ability to be well-sealed and well-insulated. 

At JBH Building, we are specialists in ICF Construction using ECO-Block. This high-quality, stay-in-place Insulating Concrete Forming system is our preferred material. ICF is involved in around 70% of our design and build projects, and some large and beautiful homes here in the Bay of Plenty.

JBH has completed several successful high spec residential builds utilising ICF (Insulated Concrete Form) structures and SIP (Structural Insulated Panels). These high-performance building materials are perfect for creating the ultimate sustainable home.  Click here ICF FAQ.

Our clients appreciate the benefits of ICF  (FAQ FORMAT)
  • The strong and durable structure
  • Disaster resistance and fire safety
  • Mould, rot, mildew, and bug resistance
  • Its superior sound-blocking ability
  • The overall ease and comfort
  • Energy efficiency and cost savings

Here's how it works...
  1. Lightweight ICF blocks are easy to get on site, saving significant time and labour costs in the early construction phase.
  2. ICF blocks are designed to stack securely together and they are customised on site to suit the building design specifications.
  3. ICF construction is completed by pouring concrete into the cavity.
  4. Once cured, the cladding is fixed. This can be wood, tile, plaster, weatherboards, or any other cladding feature.
  5. The result is a home with triple the insulation values required by the New Zealand building code, and it will outlast the 50 year durability requirement for the structure.
