Resene Construction presents the DuraTherm Insulated Foundation System, a pioneering solution for slab-edge insulation. This innovation is crucial for environmentally conscious construction and meeting New Zealand Building Code (NZBC) H1 energy efficiency requirements.
Insulating the perimeter of the foundation slab is one of the most efficient methods to improve the thermal performance of a home. Slab-edge insulation significantly reduces heat transfer, maintaining consistent indoor temperatures and reducing energy consumption.
For example, adding 33mm DuraTherm Blue Insulation with an R-Value of 1.0 can increase the overall R-Value of a 100m² floor slab to approximately 1.66. Combining underslab insulation with the slab-edge insulation system can result in the thermal performance of the concrete slab improving by 100% or more.
Additionally, insulating the perimeter helps achieve a complete thermal barrier against weather extremes, keeping your home cooler in summer and warmer in winter. Using the DuraTherm Blue Insulated Foundation System allows for full insulation up to the top of the floor slab. The DuraTherm system’s design seamlessly integrates with various foundation styles, providing robust support while enhancing the building’s thermal envelope.
An additional benefit is moisture protection. DuraTherm technology prevents moisture from penetrating the insulation cells, protecting the foundation and prolonging the structure’s lifespan. The system is shielded with a layer of hydrophobic, flexible plaster reinforced with fibreglass mesh, ensuring durability and moisture resistance. Finished with one of our premium texture surfaces and overcoated with the Resene colour of your choice, DuraTherm complements the exterior aesthetics of any building.
Resene Construction’s DuraTherm Insulated Foundation System represents a significant advancement in building technology. This innovative system is set to become an essential component for builders and developers committed to creating high-performance, energy-efficient buildings compliant with NZBC H1 standards.
