The NBS BIM object standard

The NBS BIM Object Standard defines requirements for the information, geometry, behaviour and presentation of BIM objects and gives a reassurance of quality and consistency that facilitates greater collaboration across the construction industry. This enables quick, confident and informed decision-making.

This page on the H+H website will link you to our BIM objects on the NBS Specification website.

Celcon Blocks

Building Information Modelling

Solar Grade Blocks

This highly efficient block (thermal conductivity of just 0.11 W/mK) is sufficiently loadbearing for two storey buildings and can be used below DPC.  Identified by the distinctive painted blue line, Celcon Solar Grade has a compressive strength of 2.9N/mm2 and is BBA accredited.

Standard Grade Blocks

Celcon Block Standard Grade is BBA certified and has a compressive strength of 3.6N/mm2. Its all-round performance allows a 100mm Standard Grade Celcon Block to be used consistently throughout a build, eliminating on-site confusion.  

Foundation Blocks

Available in Standard Grade (3.6N/mm2) and High Strength Grade (7.3N/mm2).  Foundation Blocks can be used to support 3 storey constructions. They are suitable for the support of solid or cavity walls, framed construction or suspended floors, including beam and block.

Plus Blocks

Celcon Plus Blocks are a longer (630mm) alternative to the to the standard (440 x 215mm) Celcon Block and comes in a range of thicknesses which are suitable for the same applications.

Jumbo Bloks

Jumbo Bloks are produced with the latest technology, offering a high degree of dimensional accuracy, making them ideal for use with Celfix mortar (Mortar).

Jumbo Bloks are made to sizes of 630 x 250 mm and are available in Solar Grade (2.9N/mm2), Standard Grade (3.6N/mm2), High Strength Grade (7.3N/mm2) and Super Strength Grade (8.7N/mm2).

Celcon Vertical Wall Panels

Vertical Wall Panels can be used in housing as well as commercial or mixed tenure projects. Suitable for internal partition and the internal leaf of an external wall, the products offer solutions to meet the requirements of the Building Regulations for education, health, care homes, retail outlets, hotels, commercial buildings, leisure, offices as well as housing (social and private).

High Strength Grade Blocks

H+H’s Celcon Blocks High Strength Grade (7.3N/mm2 – identified with a black stripe on the block) are ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.

Super Strength Grade Blocks

H+H’s Celcon Blocks Super Strength Grade (8.7N/mm2 – identified with a red stripe on the block) are ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.
