Context

Architects designing a single bungalow in Norfolk to Passivhaus standards specified H+H’s Celcon Block Standard Grade for the internal leaf and external leaf to the timber boarded elevations on the structure. H+H products were selected due to delivery time, speed of construction, stability and thermal mass.

Product supplied

140m2 of aircrete blocks: H+H 140mm and 100mm Celcon Block Standard Grade 3.6N - thermal conductivity of 0.15W/m2K.

The inner aircrete shell took three weeks to build before being faced with timber and brick.

Outcome

The brick faced walls have a U-value of 0.098W/m2K and the timber-faced walls have a U value of 0.096 W/m2K - a 300mm cavity is fully filled with Polypearl Platinum graphite EPS bead insulation.

H+H’s Celcon Block Standard Grade is a key contributor to achieving these results with a thermal conductivity of 0.15W/m2K.

Product benefits

  • Provides a fast, watertight masonry shell to enable internal trades to start sooner
  • Meets or exceeds Part L and Part E of the Building Regulations
  • Simplifies the construction process
  • 80% recycled material
  • A+ rating in BRE Green guide
  • Excellent thermal and acoustic properties
  • All components for the Rå Build method available off the shelf
  • Block-work is highly adaptable, allowing for any last minute design changes
  • Air permeability of 0.12m³/hr/m²
  • Celfix mortar can be stored within footprint of building - small quantities mixed as required
  • Class 0 rating for surface spread of flame

Applications

  • Internal and external leaf in cavity walls
  • Solid walls
  • Separating / party walls
  • Flanking walls
  • Partitions
  • Multi-storey
  • Foundations
