Future Homes Standards 2025 are all about improving the thermal efficiency of new homes in the UK and to ensure lower running costs, which in turn will reduce the carbon footprint of a new home.
The changes proposed in the Future Homes Standards consultation are to look at the Notional Dwelling specification for carbon emissions, Primary Energy and the Fabric Energy Efficiency Standard closely considering U-values, thermal bridging values (Psi Values), as well as the thermal mass of the structure, which affects internal and solar gains as well as airtightness of the property.
Future Homes Standard in 2025 is suggesting that the heating demand of a dwelling should be limited to 15-20 kwh/ m2/year, which would require far higher thermal efficiency in the fabric of the building, in particular the U Value of the walls as well as using materials that can offer better Thermal Mass with potential target U Values being circa 0.15 W/m2K.
Using traditional masonry cavity wall construction to reach these types of U values would need to have wall thickness to be as high as 430-450mm wide with cavities being more than 200mm wide using a full fill insulation system which has implications on the foundation widths used as well as requiring more robust wall ties with design consideration in the structural performance against wind and sway.
The answer is to design external walls using the Juwo SmartWall systems as a Monilithic Single Skin structure incorporating the insulation requirements within the structure of the blocks and to reduce thermal bridging (Psi Values) eliminating mortar or adhesive on the interlocking vertical joints and using a thin bed adhesive bond to the horizontal plane.
No Cavities. No Wall Ties. No Additional Insulation. Resulting in a quicker and subsequently less expensive construction to build. The Juwo SmartWall Monolithic Single Skin clay blocks are manufactured to include all the insulation values required within the system, using one of three main products. The “S” system is our standard aerated product. The “MZ” system which includes mineral wool within the structure, and our “RX” system which uses our PoroTec insulation bead, again bonded within the block.
All our Juwo SmartWall systems do not require a wall tie for structural stability nor a cavity to provide the required U values from 0.18 to as low as 0.11 W/ m2K. Manufactured with a tolerance of 1mm in height, the Juwo SmartWall range of systems reduces the Thermal Bridging (Psi Value) by over 15% as well as having a high Thermal Mass being a masonry clay based product. In addition, the Juwo SmartWall system comes as a complete package that includes lintels, corner and shapedblocks, insulated mortar, adhesive and applicators.
Juwo SmartWall systems are structural blocks which can be used to any height required and have been used in the UK and Europe for many years for load bearing and non-load bearing walls, for external & internal applications. They have full approval and comply to BS EN 771-1 and carry both a UK CA & CE mark with an A1 fire rating, making them the ideal building system for low and high rise developments as well as for the self-builder.
JUWO SMARTWALLTM BENEFITS:
- Excellent Thermal Performance can offer U Values as low as 0.11 W/m2K
- Meets & Exceeds Building Regulation requirements
- Quick Construction Time
- Single solid wall construction

The Juwo SmartWall systems are manufactured from Clay therefore possibly one of the most sustainable materials used in construction. It is a natural material that it easy to work with and provides a comfortable living environment.
Juwo SmartWall system delivers a much faster build time. The thin joint adhesive allows you to continually work without being restricted to the number of lifts in a day, on average, up to 40+ sqm can be achieved per day.
Juwo SmartWall being a monolithic building system, means that you have just one skin for your building structure, no cavities, therefore minimising areas for complicated detailing and areas for insulation to be missed.
The Juwo SmartWall system provides a thermal bridge free method of construction without the need for complicated detailing.
