Metal roof insulation is crucial for improving energy efficiency, acoustics, comfort and living standards in both modern residential and commercial buildings.
In an uninsulated building, the main source of energy loss 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.
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 reduce fuel costs.
Our metal roof applications utilise both high-density and medium-density products. High-density products support the metallic rain screen directly. Medium-density products – typically rolls – act as an infill between the two metallic layers and their metal carrier.
Installing effective metal roof insulation barriers offers protection from rain, hail and snow during winter, and overheating in the summer.
Stone wool insulation also provides excellent acoustics for a metal roof – protecting against urban noise pollution and noise from the weather, such as rain and hailstones, which often pose a problem for metallic roof coverings.
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.
U-value calculator tools and technical support are available at your local ROCKWOOL organisation, to help determine the exact product and insulation thickness required to fulfil your requirements.
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.
Our insulation is A1 or A2, s1, d0 – non-combustible, fire classified – built to contain fire and preventing it from spreading5
As 66 per cent of energy consumption in buildings is used for heating, cooling and ventilation6, our insulation helps maintain an optimum indoor temperature and climate.
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.
Our insulation comes in a variety of shapes – and can be modified with ease to fit your design and architectural needs.
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.
We work with professional local roofers, enabling quick response times and multiple quotes for an optimal offering.
Stone wool can be used again and again, making it one of the most recyclable and sustainable materials in the building world7
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.
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.
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.
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.
Key tips for installing ROCKWOOL metal roof insulation:
ROCKWOOL products are designed to be both energy efficient and high quality.
We embed our aims and values in everything we do, helping to create functional and sustainable insulation to improve modern living and the environment.
Our insulation is designed to ensure buildings and domestic properties pass international standards. This requires buildings to be:
