The Foreverbreathe Specification builds healthy, sustainable homes

The homes in which we live our lives have a direct impact on our health and the environment, so the way we build them matters. An understanding of this cause and effect led to the development of the Foreverbreathe Specification – the new standard in healthy, sustainable building.




Breathe easy in a Foreverbreathe Home

The Foreverbreathe Specification delivers exceptional air quality and energy efficiency through a sophisticated combination of high-performance materials that work together to naturally reduce indoor humidity while managing air tightness. Mechanical ventilation is limited to bathrooms, kitchens, and laundries. This saves on energy bills for ventilation, heating, and cooling.

Components used in the specification are carefully chosen to remove hazardous chemicals from the home, and ensure materials are sustainable and high performing. With the Foreverbreathe Specification, you can breathe easy in the knowledge that your space is a healthy place.



How it works

What makes the specification so good is the Foreverbreathe Wall System and the exothermic performance it provides. This clever hygroscopic system enables moisture created within the home to be absorbed into wool insulation.

Through a completely natural exothermic reaction within the wool, this moisture is vapourised and in so doing releases energy in the form of heat. And it does this for FREE, 24 hours a day, without the reliance on costly whole-home mechanical ventilation systems.




Performance Benefits

Human Health – Future Generations

Sustainable materials used within the specification establish airtightness and energy reductions, without the use of high volumes of plastics, polystyrene, or harmful chemicals, which harm the environment and the air we breathe.

Exothermic Performance

A clever combination of materials enables the absorption of moisture into wool insulation to ignite a completely natural exothermic reaction within the wool which releases energy in the form of FREE heat. Wool fibre’s ability to absorb and release moisture without derogation is well documented. Learn more - Moisture regulation wool fibre insulation verse glass fibre

100% Sustainable

True to aims of sustainability, the Foreverbreathe Specification fulfils the needs of current generations, without compromising the needs of generations to come. Materials used have been carefully selected with consideration to their long-term impact, to ensure positive outcomes for the environment, human health, and social well-being.

Breathable – Vapour Permeable

A clever combination of vapour permeable building components work in harmony to provide air-tightness, control humidity, and remove moisture from the indoor space.

Energy Efficient

As the Foreverbreathe Specification manages air-tightness and moisture so well, it provides an exceptionally comfortable environment that is easy to heat & cool.

Carbon Capture & Storage

Foreverbreathe Specification includes components that capture & store carbon in their raw state before being made into wall & ceiling linings, claddings, flooring, and framing.
