JACKON Building Systems selected for first ever ‘Passive House Standard’ dwelling in Scarborough

JACKON building systems were chosen for both the foundations and external walls to help achieve Scarborough’s first ever passive house standard private dwelling, achieving a net positive, zero energy home.

Designed by Architects Samuel Kendal Associates, this three-storey sustainable family home is embedded deep into the Scarborough Hillside, and comprises a semi-submerged basement housing a garage and music room, a lower ground floor for three large bedrooms and a top floor consisting of a large open plan kitchen and living spaces.

JACKON Building systems, JACKODUR Atlas raft foundation and THERMOMUR ICF, were the client’s preference and were chosen for their versatility, energy efficiency, speed of construction and cost effectiveness to help them achieve their aims of becoming net zero. 

The specialist ICF contractor Bondmor, working closely with JACKON’s leading approved distributors in the North of England ICF Building Solutions Ltd, utilised JACKODUR ATLAS for the foundation of the build. Bondmor and ICF building solutions worked hand in hand with the architect and the clients prior to construction to design the building around the JACKON systems to minimise wastage and increase on-site efficiency. The JACKODUR ATLAS was the ideal choice, as a zero waste, fully bespoke, cut-to-size foundation system helping achieve U-values of 0.12 Wm²K and a compressive strength of 500 kPa. The innovative design of the XPS system assisted the contractor in constructing the foundation in a matter of days, eliminating all thermal bridges whilst maintaining high performance insulation values with zero waste.

JACKON’s THERMOMUR 350HD blocks were utilised for all the subterranean lower ground floor walls. Selected for its 200mm concrete core paired with its energy efficient properties (U-value 0.22 Wm²K). Bondmor were able to construct the 6m retaining ICF walls quickly without the need for additional structural support from further retaining methods, saving the client time and money. The THERMOMUR 350HD blocks were externally clad with 100mm JACKODUR XPSK300 to seamlessly line up with the THERMOMUR 450 blocks above in order to achieve a U-value of 0.09

Chosen for its high-performance insulation values and its cost effectiveness compared with other similar building systems, the above ground exposed walls were installed with THERMOMUR 450 achieving U-values of 0.11 Wm²K. This wall structure far exceeds the requirements of today’s building regulations and surpasses Passive House Standards (U-value 0.15 Wm²K). 

Bondmor were able to effectively construct the ICF walls and openings to allow for ease of follow-on trades. Pockets were built into the ICF walls to allow for the universal beams to support the block and beam floor structure, openings were squared and formed to pre-determined window dimensions. This allowed the client to reduce the lead time on the window manufacturing and installation. Gable ends were cut to precise angles to allow structural bearing for the SIPS roof panel. Penetrations were installed for all service locations prior to concrete placement. JACKON ICF systems are metric dimensions with internal and external fixing points running vertically through the blocks every 150mm.

The JACKON Building System took just 27 days to construct. The clients were very impressed with the speed and efficiency involved. ICF construction is fast becoming a widely recognised modern method of construction for developers and self-builders. It integrates both insulation and concrete in one permanent formwork solution that provides many offsite, onsite and end-user benefits. These include: high performance insulation values and significantly improved airtightness, leading to reduced heating and cooling requirements, excellent acoustic performance, improved fire resistance, enhanced capabilities in extreme weathers with added benefits of reduced maintenance, as well as being accepted by mortgage lenders, home insurance and planning departments. 

JACKON brings over 60 years’ expertise in EPS and XPS manufacturing to this market. JACKODUR ATLAS is manufactured from XPS (extruded polystyrene), while THERMOMUR uses EPS (moulded expanded polystyrene) to create the formwork. The two systems fully integrate, leading to a reduction in the need for extra on-site labour.

JACKODUR® ATLAS is the foundation for success

An amazing self-build property built on a JACKODUR® ATLAS foundation slab has won the Small Project Category of the 2021 Passivhaus Awards.

The property, Larch Corner, is located in Warwickshire and predominantly features modern timber engineering in its above ground construction. However, the building is based on JACKODUR® ATLAS foundation system from JACKON.

The JACKODUR® ATLAS Extruded Polystyrene (XPS) insulation and formwork system is an intelligent and efficient thermal insulation system for floor slabs and is ideal for constructing the foundations of energy-efficient houses.

The system comprises an economic interlocking system, which eliminates thermal bridges and has excellent compressive strength properties. Supplied cut to size, rapid and problem-free construction is assured.

In this particular property the floor has a U-value of 0.101 W/m2K and the building overall is claimed to be the most airtight house in the UK and the third most airtight house in the world, exceeding current building regulations 244 times over! 

Thanks to the elimination of heat loss through the floor of the structure, JACKODUR® ATLAS plays a critical role in helping Larch Corner achieve its net zero credentials. The owner and builder says that he was able to turn off the heating system in the house, provided by an air source heat pump and photovoltaic array, in March and hasn’t needed to use it since.

JACKON’S expertise in the creation of building materials for low energy buildings goes far beyond the manufacture of foundation systems. The company has over 60 years’ expertise in manufacturing both XPS and Expanded Polystyrene (EPS). While JACKODUR® ATLAS uses XPS, the company’s THERMOMUR® Insulating Concrete Formwork (ICF) EPS system can be used in combination with it, to create highly energy efficient buildings.

U-values and why they matter

If you have been involved in any type of new build or refurbishment project lately, you have probably heard about U-Values. But what’s it all about and why does it matter?

The U-value is a measure of thermal transmittance through the fabric of a building, basically how well insulated it is. The lower the U-value, the better the building is at retaining heat within it, so the less energy is required to heat it (or cool it).

This is one aspect of improving the environmental performance of a building. Historically in the UK more emphasis has been placed on the use of renewable energy technologies to improve the green credentials of a building, for instance micro generation with wind turbines, solar panels and ground source heat pumps.

While these all have a role in helping meet the current environmental targets of the construction industry, their impact is reduced if the building fabric itself has a high thermal transmittance. Indeed the biggest gains in reducing CO2 emissions from buildings and also saving cost with regard to a building’s energy requirement are to be found in improving the fabric of the building itself – enhancing insulation and reducing thermal transmittance.

JACKON therefore very much welcomes the fact that the Government’s new Future Homes Standard is adopting a ‘fabric first’ approach in its drive to secure cuts in emissions of up to 80%. This is set to be a key part of the construction industry’s framework going forward, underpinning the planned green recovery of the housebuilding market in particular.

Achieving the lowest possible U-value is also a key criteria for a building to gain Passivhaus certification, since it is a requirement to achieve a 75% reduction in space heating requirements, compared to a standard UK new build.

Thermal transmittance, the U-value, is the rate of transfer of heat through a structure divided by the difference in temperature across that structure. The unit of measurement is W/m²K. Workmanship and installation standards can strongly affect the thermal transmittance. If insulation is fitted poorly, with gaps and cold bridges, then the thermal transmittance can be considerably higher than desired. Thermal transmittance takes heat loss due to conduction, convection and radiation into account. 

The U-value measurements can be calculated theoretically by considering the thermal transmittance of each layer of the building’s fabric, and there is a calculation method included in the relevant British Standard BS EN ISO 6946: 2017. This takes into account any mortar joints in the construction and also fixing components which have the potential to cause cold-bridging. Post-construction measurements using sensors are however the most robust way of assessing actual U-values, since they are able to take workmanship into account, as well as the actual materials themselves.

The current regulations aim for a target U-value of 0.18 for external walls as a starting point to achieve a well-insulated building envelope. Insulating Concrete Formwork (ICF) constructions have been achieving this target easily for years in their basic configuration, with no “add-ons”, while other types of constructions have had to push their limits in terms of cavities, ties and expensive insulating material in order to achieve the existing levels of thermal performance. 

The Future Homes Standard is up for further consultation, ahead of final implementation in 2025, but it is clear it will be a requirement for housebuilders to build well-insulated homes, in which on-site renewable energy sources cannot be used to offset inadequate insulation at the construction phase. The Government is proposing target u-values of 0.15 for external walls and 0.11 for floors from 2025, and there will be an initial uplift in Standards, coming into effect in June next year, via an amendment to Part L of the Building Regulations which sets the standards for the energy performance and carbon emissions of new and existing buildings.

JACKON is ready for these changes and is in fact arguing for them to be even more rigorous, by setting far more demanding air tightness targets. The new targets are not a problem, since JACKON’s THERMOMUR 350 ICF in its standard EPS configuration achieves a U-Value of 0.17 W/m2K. By using upgraded THERMOMUR 350 Super EPS that figure drops to 0.15 W/m2K. The next step up is THERMOMUR 450 with a U-Value of 0.11 W/m2K, which puts the building on course to become a Zero Carbon build.
