H+H is the UK’s largest manufacturer of aircrete products. We manufacture the market leading range of Celcon Blocks, including Foundation Blocks, Plus Blocks and the H+H range of aircrete products.
H+H aircrete products offer a complete building material that meets the requirements of the Building Regulations, with the flexibility to offer solutions to hospitals, schools, offices, industrial warehouses and housing (social and private).
Used in partition, separating and external walls (solid or cavity), firewalls and as an infill to framed construction, our products provide durability and fire resistance as well as superb thermal and sound insulation.
Main Product Ranges:
Celcon Blocks
Celcon Blocks in Solar, Standard, High Strength and Super Strength Grades are the most commonly used aircrete block in the H+H range. All Celcon Blocks are BBA certified, are fire resistant (100mm walls, up to 4 hours, 2 hours if loadbearing) and have been classified 0 surface spread of flame and non-combustible to Class A1 (the highest class).
Celcon Block Solar Grade
Celcon Blocks Solar Grade is principally used where enhanced thermal performance is required. With superior thermal conductivity Solar Grade Celcon Blocks are suitably loadbearing for two storey buildings and can be used below DPC.
Celcon Block Standard Grade
Celcon Blocks Standard Grade is BBA certified and has a compressive strength of 3.6N/mm2. Due to its all round performance, it is possible for a 100mm Standard grade Celcon Block to be used throughout a build, eliminating on-site confusion.
Celcon Block High Strength & Super Strength Grade
H+H’s Celcon Blocks High Strength Grade (7.3N/mm2) and Super Strength Grade (8.7N/mm2) are used principally 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.
Celcon Plus Blocks
Celcon Plus Blocks are an alternative to the 440 x 215mm face format block and are suitable for the same applications. They are longer at 630mm long and come in a variety of thicknesses.
Celcon 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.
Beam & Block Floorblock
Beam and Block floors are constructed using Celcon Blocks. They are lightweight, so easier, quicker and safer to lay and allow for an economy of scale and reduction in laying times.
Multi Plates
H+H Multi Plates are a new generation of aircrete products that build on the efficiency of thin layer construction. At over 2 times the size of a traditional (440 x 215mm) block, Multi Plates and the Thin-Joint system will deliver significant savings in site productivity.
Jumbo Bloks
Jumbo Bloks are produced with the latest technology, offering a high degree of dimensional accuracy with sharp arises, which make them ideal for use with Celfix mortar.
Celcon Block Coursing Units
Coursing Units are produced from the same material as all H+H aircrete and are suitable for the same applications as conventional size Celcon Blocks, allowing consistency within the building fabric.
Celfix Mortar
Celfix Mortar is cement based and supplied as a dry, pre-mixed powder in 25kg bags. It has been designed to replace the traditional sand:cement mortar and is used with building with our Thin-Joint System. Celfix Mortar starts to set within 10 minutes of application and approaches full design strength in just 1 to 2 hours.

H+H Aircrete Passivhaus shortlisted in Building Performance Awards
Aircrete Passivhaus shortlisted in Building Performance Awards
5TH FEBRUARY 2019
The Cameron Close development on the Isle of Wight, built using H+H’s Thin-Joint blockwork, has been shortlisted in the prestigious Building Performance Awards run by the Chartered Institution of Building Services Engineers.
These awards are distinctive in the construction industry as they recognise the performance of buildings in use – in this case the dwellings have been monitored for two years since completion by independent consultants WARM. This monitoring process provides robust evidence that the homes perform absolutely as intended, providing very high levels of energy efficiency and low running costs for the occupants.
H+H’s Thin- Joint System of aircrete blocks and Celfix Mortar was a key element in the construction of this Passivhaus development, comprising 16 semi-detached houses and 12 sheltered accommodation apartments on the Isle of Wight.
H+H Sponsors Merchant ‘Independent Rising Star of the Year’ Award
H+H Sponsors Merchant ‘Independent Rising Star of the Year’ Award
11TH FEBRUARY 2019
H+H is delighted to announce its sponsorship of the ‘Independent Rising Star of the Year’ category at the Builders Merchants Journal (BMJ) Industry Awards 2019. Now in its second year, the awards will deliver several new categories which reflect the breadth of the sector. The winner will be announced on Friday 19 May at a special luncheon.
This award aims to recognise an individual working in an independent merchant chain who has the ability, drive and determination to rise to the very top. Unlike most traditional industry awards, the accolade will be voted on by the entire industry via a secure online portal rather than a selected judging panel.
Editor-in-Chief Fiona Russell-Horne said: “BMJ is the UK’s longest running industry title, serving the construction distribution supply chain for near 100 years. In that time, we’ve learned that the most important part of the any industry is the people and the brands that they promote. The aim of the BMJ Industry Awards is to reflect the massive pool of talent we have out there, celebrating the brands, names and businesses that keep the merchant sector thriving.”
As a partner in wall building, H+H is a company that actively promotes long-term partnership with its merchant customers and is always keen to support individuals who are demonstrating excellence within the sector.
A total of 13 nominees are vying for the top prize. Voting is currently open at https://www.bmjindustryawards.co.uk/vote/ and will close on Friday 22 March 2019. The winners for each category will be the entries which have received the most votes overall and will be announced at the awards ceremony on 19 May.
