Pitched roofs that deliver energy efficiency, with less waste

An uninsulated home loses heat through the roof. As a result, the home is cold in winter, hot in summer, and expensive to heat and cool year-round. NatHERS has set minimum energy efficiency standards for Australian homes to help improve the energy efficiency of homes and roof insulation is critical to achieving that goal.

Our Technical Services team are here to guide you through every step of the process.

Benefits of our pitched roof insulation products

Insulation for Pitched Roofs

Knauf Insulation provides insulation for cold roofs insulated at ceiling level, and warm roofs insulated at rafter level. All our solutions deliver the thermal performance you need to achieve an energy efficient building. We offer non-combustible insulation that is quick and easy to install, and our glasswool insulation offers a lower-carbon choice compared to other mainstream insulation options.

Pitched roof insulation products that deliver thermal performance, with less waste.

Thermal performance

The thermal performance of the roof is fundamental to achieving an energy efficient building.

Knauf Insulation’s glasswool insulation is flexible, so it can fit snugly between joists.
Our roof products will recover their thickness when unwrapped, helping to fully fill the space between joists or rafters, and offcuts can be used to fill gaps around penetrations.

This flexible quality of glasswool helps to reduce unwanted air gaps, reducing thermal bridging and maximising thermal performance.

Fire safety and air quality

Fire safety performance and improved air quality help to protect occupant wellbeing.

We offer non-combustible insulation with the highest AS/NZS 1530.1 fire compliance for the unfaced blanket and 1530.3 for the finished foil-faced blanket. So, our products will not significantly contribute to the development of a fire should it occur.

Our insulation products also contain very low levels of volatile organic compounds (VOCs), which can be harmful to human health, and hold the Eurofins Indoor Air Comfort Gold certification. They contain no added formaldehyde and are DECLARE ‘Red List Free’, contributing to a healthier indoor environment.

Sustainability and Moisture resistance

Efficient, sustainable insulation solutions benefit installers, housebuilders, and homeowners.

Roof products are also compression packed, expanding in thickness when unwrapped. This makes for easier transportation and reduces road miles.

Our glasswool insulation is manufactured with ECOSE®, our unique plant-based binder that is low-carbon. This reduces the embodied carbon of the product and the building.

The foil facing on Space Blanket provides condensation control to prevent moisture build-up in the roof system. The foil is laminated wider than the insulation to allow overlap of adjacent rolls and ensure continuous condensation control.
