The Foundation in Parnell is a recent project highlighting the efficiency of Outright Insulation’s products in meeting and exceeding H1 requirements. Designed by Peddlethorp and executed by European Stone Masons, this project utilises ROCKWOOL ThermalRock S80 in various thicknesses to achieve superior energy efficiency. Situated on the historic Parnell grounds of Blind Low Vision NZ, it is the first stage of an upscale retirement living development. One of three new buildings planned to harmoniously integrate into a rich heritage precinct, The Foundation Retirement Village in Parnell features 46 apartments across four floors and the building has commercial office space at ground level. The design pays homage to neighbouring Category 1 heritage-listed buildings including the iconic Jubilee Building, Pearson House and the nearby Auckland War Memorial Museum.

Superior thermal and acoustic performance

ROCKWOOL ThermalRock S80 is renowned for its exceptional thermal and acoustic properties. The Foundation used two sizes of ROCKWOOL — Thermalrock S80 x 50mm with an R Value of  R1.5  and Thermalrock S80 x 75mm with an R Value of 2.25. Installed as continuous insulation, it minimises thermal bridging, ensuring optimal thermal performance. This continuous application, known as "outsulation," significantly reduces the energy required for heating and cooling, aligning perfectly with the stringent requirements of H1. The result is a building that not only meets but exceeds the new insulation standards, providing enhanced comfort and energy efficiency.

Fire resistance and sustainability

One of the standout features of ROCKWOOL ThermalRock S80 is its superior fire resistance. Being non-combustible, it adds a crucial layer of safety to large commercial buildings and their occupants. Furthermore, ROCKWOOL is hydrophobic and non-hygroscopic, meaning it repels water and does not absorb moisture, yet remains vapour permeable. This unique combination allows for effective moisture management, reducing the risk of condensation-related issues within the building envelope.

ROCKWOOL ThermalRock S80 is also a sustainable option. Made from natural stone and recycled materials, it is both reusable and recyclable. The Environmental Product Declaration (EPD) for ROCKWOOL aligns with global sustainability goals, ensuring that the product supports environmentally responsible building practices.

Reducing operational costs and enhancing energy efficiency

The smart design and detailing involved in the installation of ROCKWOOL ThermalRock S80 ensure that it easily exceeds H1 values. By reducing thermal bridging and enhancing overall insulation, the building’s operational costs are significantly lowered. This also reduces energy consumption, leading to lower utility bills and a smaller carbon footprint.

Benefits of continuous insulation with heavyweight cladding

In The Foundation project, ROCKWOOL ThermalRock S80 was used in conjunction with a classical stone cladding. This combination not only adds aesthetic value but also enhances the building’s energy performance. The heavyweight cladding works synergistically with the ROCKWOOL insulation to provide additional thermal mass, further stabilising indoor temperatures and reducing reliance on mechanical heating and cooling systems.

Conclusion

The Foundation in Parnell, with its use of ROCKWOOL ThermalRock S80, is a prime example of how Outright Insulation’s products meet and exceed the new H1/AS2 standards for buildings over 300m². With superior thermal and acoustic performance, excellent fire resistance and sustainable properties, ROCKWOOL ThermalRock S80 ensures that large commercial buildings are not only energy-efficient but also safe and environmentally friendly. Through smart design, continuous insulation and advanced monitoring systems, Outright Insulation is leading the way in delivering energy-efficient solutions for the future.
