Celcon Vertical Wall Panels: A Modern, Masonry-Based Offsite Construction Solution

Celcon Vertical Wall Panels (VWPs) are a high-performance, offsite-manufactured solution that meets the growing demand for Modern Methods of Construction (MMC) in housebuilding. These storey-height aircrete panels are designed for rapid construction of external walls, separating walls, and internal partitions and are fully compliant with MMC Categories 2, 3, and 6.

Fast, Compliant Installation with Masonry Benefits

Celcon Vertical Wall Panels are craned into place on standard foundations and fixed using H+H’s high-strength, fast-setting mortar, creating a 2mm airtight joint. This system allows the full structural shell of a typical house, from damp-proof course (DPC) to roof, to be completed in just five days. When paired with prefabricated timber floors and roofing systems, VWPs deliver a complete Category 2 MMC solution, combining offsite speed with the reliability of masonry.

Each unit is installed by a three-person team and a crane operator, ensuring a consistent and efficient build process. This method helps overcome skilled labour shortages, reducing delays on site.

Skilled trades such as carpenters, plumbers and plasterers can be easily upskilled to install VWPs, broadening the labour pool and further enhancing the efficiency of this Modern Method of Construction.

A Complete Offsite Construction Solution

Vertical Wall Panels are precision-manufactured offsite in a controlled factory setting, ensuring consistent quality, reduced waste and a lower environmental impact. Supplied ready for immediate installation, they significantly cut on-site construction time and improve project predictability.

As a faster-build alternative to timber frame MMC systems, VWPs offer all the proven benefits of masonry, strength, fire resistance and long-term durability. They integrate effortlessly into coordinated housebuilding packages, working seamlessly alongside other prefabricated components to support efficient, scalable construction across projects of any size.

Performance You Can Trust

Homes built using aircrete and VWPs benefit from a wide range of long-term performance advantages:

  • Excellent fire resistance
  • Superior thermal insulation for energy-efficient homes
  • Robust acoustic performance
  • Resistance to damp and mould
  • Exceptional build strength and longevity

These benefits contribute to sustainable, healthy living environments and align with modern regulatory and consumer expectations. Environmental Product Declarations (EPDs) are available for Celcon Vertical Wall Panels, further supporting transparency and sustainability in construction.
