Innovations for housing constructionusing concrete and masonry
Masonry construction
• Many uses of masonry in construction of new homes
• Includes structural concrete blocks on the inside

Innovation using masonry
• New ancillary products to facilitate detailing and construction using ‘traditional’ materials
• Evolution of masonry products themselves
• New guidance and tools to facilitate detailing for high performance
• Innovation in manufacturing and delivery
Lintels to reduce thermal bridging Extra wide insulating, structural cavity closers
Innovative ancillary products

Innovative ancillary products
Load bearing insulation to reduce thermal bridging
Concrete & polystyrene composite blocks
Foam glass blocks Structural insulating foam
Innovative ancillary products
Low conductivity wall ties
• Type 1,2 & 4 basalt fibre tie
• Thermal conductivity is 20 times less than a standard stainless tie.
• Suitable for large cavities.
5
New insulation systems
• Proprietary full fill with integrated 10mm vent.• Can achieve a U-value of 0.17-0.18 in a 100mm cavity

Pre-calculated thermal bridging Ψ values
(Aggregate blocks)(Aircrete blocks)
New data sheets for details on line, using most types of concrete blocks
• Highly insulating light-weight concrete
• Special dimensionally accurate aerated blocks
• Thin-joint mortar system
• 2-3mm joints
• No pointing
• Brickwork is removed from the critical path
• ‘Jumbo’ blocks available
Innovative concrete products

Storey high aircrete panel system
Innovative concrete products
• Watertight shell can be completed in a week
• External skin can be any form of masonry
• Same thermal and structural performance as aircrete blocks
SIG house system using Celcon panels from H+H
External insulation/ solid wall construction
• Simple solution for avoiding thermal bridges
• Optimises thermal mass
• Expanded market and range of rendered insulation systems
New ways of using blockwork

‘Sustainability Matters’ British precast performance
Innovation in manufacture and delivery
• Development of alternative raw material supply
• Use of rail freight for reduced energy costs
Plasmor blocks
Expanded clay manufacture at Plasmor block factory

Offsite masonry by Forterra
Composite suspended ground floor systems
•Lightweight components increasing speed of build
•Opportunity to avoid cold bridging below floor beams
•Usually requires structural concrete topping

Insulated balcony connectors
Innovative ancillary products
Max Frank
• Structural thermal break for use with cast in situ balconies and floor slabs
• Software for thermal break calculations
11
•Prefabricated, insulated formwork systems for in-situ concrete (ICF’s)
•Variety of systems available (Block, panels, extruded or expanded polystyrene
•New products becoming available
