Metal Roof Insulation

Metal roof insulation is crucial for improving energy efficiency, acoustics, comfort, and living standards in both moderns residential and commercial buildings.

In an uninsulated building, the majority of thermal transmission is through the roof, making insulation a top priority.

The non-combustible nature of stone wool insulation makes it a robust choice for fire safety too. But it’s the superior sound insulation of the material which makes ROCKWOOL metal roof insulation solutions an ideal choice for built-up applications.

Why do we need metal roof insulation?

As heat rises, most energy loss is usually through the roof of a building. Metal roof insulation can enhance the energy efficiency of a building and help to lower your electricity bill.

Stone wool products act as an infill between two metal sheets effectively reduces heat transmission and rain noise from entering into the building envelope through the roof. Choices of density are available to meet building requirements.

Installing effective metal roof insulation barriers offers protection from rain, hail, and overheating on hotter days.

Stone wool insulation also provides excellent acoustics for a metal roof – protection from rain, heat, and noise, which often pose a problem for metallic roof coverings.

Calculator and savings

Metal roof insulation can help property owners and tenants save money on their energy bills by boosting energy efficiency.

A valuable investment for the future, it offers a relatively fast payback time in terms of money, energy and carbon footprint¹

Insulation thickness can be adjusted to meet a wide array of customer specifications.

The average installed density of stone wool metal roof insulation globally is around 80 – 150 Kg/m3 for high-density products supporting the metal deck, and typically around 50 – 80 Kg/m3 for lighter infill roll products.

Why choose ROCKWOOL solutions?

ROCKWOOL metal roof insulation is designed to enhance modern living, using the natural power of stone wool to provide robust energy efficiency and protection.

Made from volcanic rock and effective for the lifetime of a building², our products give you the ultimate peace of mind.

Effective insulation engineered to last³
Fire protection from stone wool which can withstand temperatures of up to 1000°C⁴
Added security and comfort
Simple and quick to install
Acoustic solutions that absorb the sounds of urban life and reduce noise

Added fire protection

Our insulation is A1 or A2, s1, d0 – non-combustible, fire classified – built to contain fire and preventing it from spreading⁵

Effectiveness

As 66 per cent of energy consumption in buildings is used for cooling and ventilation⁶, our insulation helps maintain an optimum indoor temperature and climate.

Acoustic blocking and acoustic absorbance

The lower deck plate of a metal roof can be perforated, making a “connection” from the room below to the stone wool insulation above. This means that all acoustic benefits – noise reduction, sound absorbance and sound reverberation time - can be utilised at full potential, especially when using perforated steel plates.

Adaptability

Our insulation comes in a variety of shapes – and can be modified with ease to fit your design and architectural needs.

Robust and durable

ROCKWOOL’s insulation for metal roofs is flexible and has a high point load. Metal roofing boards are stable – with no movement when exposed to heat, cold and moisture.

Value and expertise

We work with a vast number of local professionals, contact our local sales representative today to receive assistance.

Sustainability

Stone wool can be used again and again, making it one of the most recyclable and sustainable materials in the building world⁷

Accreditations

Our insulation meets all of the requirements according to the international Mineral Wool Standard EN13162. National standards are covered through further local certification schemes. Most ROCKWOOL metal roofing solutions are FM-Global approved – which is important for industrial projects.

Find ROCKWOOL products

ROCKWOOL solutions for metal roofs are durable and proven by more than 40 years of use. Our metal roof insulation is also non-combustible and will protect you, your building and inventory if a fire occurs.

Case Studies

The project

Nottingham Girls’ High School in the UK wanted a state of the art performing arts facility installed. It had to demonstrate that it had been designed to both provide suitable control of rain noise reverberation – and achieve a noise performance standard of LAeq 30dB.

The challenge

Ensuring high levels of acoustic performance was a vital part of the project. The building had to prevent sound from reaching other areas of the school – while also reducing the impact from external noises, such as rain and other bad weather.

The solution

A combination of ROCKWOOL metal and flat roofing solutions were used to make sure that the department was insulated sufficiently for both heat loss and sound.

HARDROCK Multi-Fix products and a ROCKWOOL acoustic membrane were used in combination with other products on the structural deck of the roof.

The ROCKWOOL roofing board’s open wool structure was ideal for absorbing and regulating noise in the building. Additionally, the acoustic membrane acted as a sounded deadening layer to prevent noise interruption during performances.
