Here we have provided critical design data relating to the use of Celcon blocks in different applications:
• Thermal insulation
• Acoustic insulation
• Structural design and advice
• Fire resistance
• Movement accommodation
• Applied finishes
Thermal compliance
Due to their thermal mass Celcon blocks have the ability to store and radiate heat back into a building. This helps a house act as a storage heater, absorbing heat and radiating it back into the building when the temperature drops. This reduces any dips in temperature during the winter and peaks in summer, creating a comfortable environment. The range of Celcon products, all with excellent thermal properties, means that H+H UK can offer blocks for foundations, cavity walls, solid walls and beam-and-block floors that satisfy Building Regulations energy efficiency requirements.

Acoustic
H+H UK's products can easily achieve the sound insulation requirements to the Building Regulations. The solutions within our Acoustic Compliance guide are backed by testing both on-site and in laboratory conditions. Celcon products have excellent sound insulation qualities, which allow their continued use throughout the building to achieve the requirements for internal walls and floors (only applicable in England and Wales) and separating walls and floors including their associated flanking walls (applicable in England, Wales and Scotland).
Within Acoustic Compliance guide below you will find: Technical information, explaining the Aircrete mass law and how Celcon blocks match the performance of dense and aggregate block masonry walls of the same thickness.

Building with aircrete
Our blocks provide simple solution and our Building with aircrete guide has been carefully designed with an emphasis on the practical use and application of H+H Celcon products. Our Building with Aircrete brochure includes detailed guidance on stacking and storage, recommended mortar types and strength, laying blocks, cutting, chasing and fixing to blocks, applying internal and external finishes.

Fire resistance
Celcon blocks do not burn and can be used to contain or prevent the spread of fire within a building. Up to a 4 hour fire resistance can be achieved with a regular 100mm thick block making it the perfect choice for protecting our colleagues and loved ones.

Accommodation of Movement control
Movement can be due to expansion and contraction (shrinkage) related to the physical characteristics of the materials and the environment, and to differential settlement or other movement of parts of the structure. Such movements are termed either reversible or irreversible. For more information about movement control and the use of movement joints and bed joint reinforcement download our Designing with aircrete brochure.

Air tightness
Aircrete’s Air Permeability Tests undertaken by Building Services Research and Information Association (BSRIA) have shown that Celcon aircrete blockwork achieved an air permeability of approximately 0.12m3/hr/m2 measured at 50 pascals. The corresponding value is 1.04m3/hr/m2 for H+H Celcon aircrete using general purpose mortar. The use of thin layer mortar will improve this.
