Transform Your Build with Insulated Concrete Forms (ICF)

At Ridgewood Construction, we specialise in cutting-edge ICF (Insulated Concrete Forms) construction that delivers exceptional thermal performance, structural integrity, and long-term value. Our expertise in ICF systems ensures your project benefits from the latest in sustainable building technology.

What is ICF Construction?

Insulated Concrete Forms are lightweight blocks made from Expanded Polystyrene (EPS) that interlock to form the shape of exterior walls. Concrete is then poured into the cavity, creating a reinforced concrete wall that’s permanently insulated on both sides. This innovative construction method combines the strength of concrete with superior insulation performance.

Why Choose ICF for Your Project?

Exceptional Thermal Performance

  • Achieve U-values as low as 0.10W/m²K when combined with insulated foundation systems
  • Eliminate thermal bridging between walls and foundations
  • Reduce heating costs by up to 60% compared to traditional construction
  • Maintain consistent indoor temperatures year-round

Structural Excellence

  • Superior strength and durability from reinforced concrete core
  • Excellent resistance to extreme weather conditions
  • Enhanced seismic and wind load resistance
  • Long-term structural integrity with minimal maintenance

Construction Efficiency

  • Faster build times compared to traditional block construction
  • Lightweight blocks are easy to handle and position
  • Integrated insulation eliminates separate insulation installation
  • Reduces concrete requirements by 50-60% when paired with insulated foundations

Environmental Benefits

  • Excellent airtightness reduces energy consumption
  • Sustainable EPS insulation with long lifespan
  • Reduced waste during construction
  • Contributes to NZEB (Nearly Zero Energy Building) compliance

ICF System Components

Straight & Corner Blocks

High-quality EPS blocks that interlock securely to form continuous walls with minimal thermal bridging.

Cavity Closers & Headers

Specialised components for window and door openings, maintaining thermal continuity throughout the structure.

Plastic Web System

Integrated plastic webs provide structural connection while minimising thermal bridging.

Complete Thermal Envelope Solution

Integrated Foundation Systems

We combine ICF walls with advanced insulated foundation systems to create a complete thermal envelope:
  • Seamless Integration: ICF walls connect directly to insulated foundations without thermal breaks
  • Ground Condition Flexibility: Suitable for various soil types and ground conditions
  • Reduced Excavation: Optimised foundation design reduces earthworks requirements
  • Complete Insulation: Continuous insulation from foundation to roof level
