Commercial metal roofs for energy efficient buildings, designed with thermal and acoustic performance in mind

The requirements for flat roof specification are changing. Buildings must deliver increasingly higher standards of energy efficiency and fire safety. Meanwhile, commercial roofs are becoming more functional. They are now spaces for storage, recreation, and energy generation using photovoltaic (PV) panels and that comes with additional fire risk, making fire safety an essential part of your specification.

When incorporating glasswool in your system, Knauf Insulation offers roof insulation with the highest AS/NZS 1530.1 compliance for unfaced roof products. Our products also deliver thermal and acoustic performance, supporting energy efficiency and occupant comfort.

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

Benefits of our flat roof insulation products

Thermal performance

Thermal performance of the roof is essential for maintaining an energy efficient building.

Knauf Insulation’s glasswool insulation is flexible, to reduce air gaps during installation and maximise thermal performance. This creates a more comfortable environment for residential, industrial, or commercial buildings.

Acoustic performance

Acoustic performance helps to protect occupants from unwanted noise entering the building through the roof.

This is particularly important in areas that experience heavy rainfall, or for buildings with metal roofs or that are close to airports.

Knauf Insulation’s commercial roofing blankets are manufactured from glasswool, which provides the best levels of sound absorption and reduction compared to other mainstream insulants. This helps to reduce sound pollution, such as the drumming effects of rainfall.

Non-combustible and durable

Fire safety and durability are critical functions of modern commercial roof design – particularly those with solar panel installations.

Knauf Insulation’s glasswool insulation has the highest AS/NZS 1530.1 compliance, for greater peace-of-mind.

Commercial Metal Roofing

There are two basic categories of roof design: A warm roof has the insulation above the structural deck, which is thus kept warm. A cold roof has the insulation placed below the structural deck, which thus remains cold.
