• 3rd edition published 2016

• Range of fabric solutions using concrete and masonry

• Thermal performance guidance + new products and resources

3

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

Load bearing insulation to reduce thermal bridging

Concrete & polystyrene composite blocks

Foam glass blocks Structural insulating foam


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

Innovation in manufacture and delivery

New technology and manufacturing techniques is lowering the carbon footprint of masonry even further

Efficient curing chamber in new blockwork factory

‘Sustainability Matters’ British precast performance


• Development of alternative raw material supply

• Use of rail freight for reduced energy costs

Plasmor blocks

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

10

• Pre-insulated precast concrete floors reducing cold bridging

• 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

Permanent Formwork systems
