When it comes to flat roofs, international best practice is to use “warm roof” designs. These designs put the insulation above the substrate, completely enclosing the roof area with a highly efficient insulation layer. With a CodeMark certificate for added confidence, it may be installed at 1 degree for maximum design freedom.
Passive House is an approach to the building envelop designed to achieving healthy and comfortable building while consuming very little energy.
The key considerations when building a high-performance envelope are weathertightness, airtightness, insulation, thermal bridging, vapour control and cost. Optimise these factors and the results will be obvious to everyone for the life of the building.
Not building a passive house or zero-energy building? No worries, incorporating the underlying philosophy into the design will help improve the building performance significantly - even if you just go half the way.
No extra penetrations are needed in warm roof design saving unnecessary breaches in the building envelope.
A vapour barrier provides a continuous layer of membrane. The air barrier is completely sealed to prevent airflow moving through the structure.
Providing high thermal performance, continuous insulation helps maintain internal temperatures. Any R-value may be accommodated in warm roof design.
The Enertherm layer provides continuous insulation around the building envelope.
There is no condensation within a warm roof design as there is a vapour barrier installed before the dew point.
Installing a Nuratherm Warm roof on metal tray saves money. Renew of old roofs are often much cheaper with Nuratherm
“'We chose the 100mm PIR boards because we could not find anyone else who could provide the level of flat roof insulation to achieve the performance we needed and could back it up with performance data'.”
Raise awareness of the climate and biodiversity emergencies and the urgent need for action amongst our clients and supply chains.
Nuralite is committed to its role highlighting pathways to zero carbon with the construction sector. This has resulted in real change internally and with partner companies.
Share knowledge and research to that end on an open source basis.
Nuralite is transparent about changes it has made with a view to encouraging others to follow.
Evaluate all new projects against the aspiration to contribute positively to mitigating climate breakdown, and encourage our clients to adopt this approach.
Our warm roofs are robust & durable systems which are also vital to meeting the goal of zero energy buildings.
Upgrade existing buildings for extended use as a more carbon efficient alternative to demolition and new build whenever there is a viable choice.
Upgrading the current stock of buildings so they are more fit for purpose instead of demolition is critical. Nuratherm warm roofs can be retrofitted to membrane and metal roofs to extend life and improve building performance.
Adopt more regenerative design principles in our studios, with the aim of designing architecture and urbanism that goes beyond the standard of net zero carbon in use.
Flat roofs are the best option for green building. They can be used for energy production with solar panels, storm water reduction with green roofs or additional usable space with roof decks.
Accelerate the shift to low embodied carbon and non-toxic materials in all our work.
Net Carbon Zero certification means that Nuralite has actively worked to ensure from the factory to the project site net zero carbon is created. Our key products are all non-toxic and have Environmental Product Declaration.
