Flat roof insulation is crucial for improving the energy efficiency, comfort and living standards in buildings.
In an uninsulated home, the majority of heat is lost through the roof.
ROCKWOOL flat roof insulation provides excellent thermal, acoustic and fire-resistant solutions for both commercial and domestic projects.1 We offer a wide and versatile range of premium-quality stone wool roof products which help to improve comfort and reduce carbon emissions.2
As heat rises, most energy loss is usually through the roofing area. Flat roof insulation is an essential tool that can enhance the energy efficiency of a building and reduce fuel costs.
Creating more effective flat roof barriers also offers your building further protection from the unpredictable outdoor climate, including overheating in warmer climates and rain and snow in cooler regions.
From high rise apartment blocks, to residential designs, industrial units, large commercial facilities and schools or hospitals, flat roofs are an integral part of modern building design.
Constructions such as terraces, rooftop gardens, blue roofing with water retention and roof spaces which are used for solar purposes are becoming ever more popular. This growing trend for functional roof spaces brings even more demand for effective insulation, helping to enrich the space available on top of your building.
Roof insulation is very cost competitive when saving energy consumption overall – and provides a key, valuable investment for the future.
In addition to this, flat roof insulation often has a relatively fast payback time in terms of money, energy and carbon footprint.1
There is no ‘one size fits all’ answer to how much flat roof insulation you’ll require. Since there is usually no limitation to the installation height on a roof, and ‘the sky is the limit’ so to speak, insulation thickness can be adjusted to almost any possible customer specification and local regulatory energy demand.
The average installed density of stone wool loft insulation globally is around 90 – 160 Kg/m3.
You can use the tools and calculators on our local pages to work out the potential cost savings you could make.
ROCKWOOL flat 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 often effective for the lifetime of a building1, it offers you the ultimate peace of mind.
Our insulation is A1 or A2, s1, d0 fire classified, being non-combustible and built to contain fire – preventing it from spreading.5
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.
Sound reduction is another key feature. Our insulation can help to absorb and block out noise from traffic and people.
Our insulation comes in a variety of shapes and can be modified with ease to fit your design and architectural needs. To avoid ponding water on the roofing membrane, ROCKWOOL ‘Cut to Fall’ solutions can be used to make sure that water is guided to the outlets of the roof.
ROCKWOOL structure is flexible, has a high point load and roofing boards are stable – having 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 world.1
ROCKWOOL products meet all requirements according to the International Mineral Wool Standard EN13162. National standards are covered through further local certification schemes. Most ROCKWOOL flat roofing solutions are FM-Global approved – which is vital for all industrial projects.
Wilmcote House in Portsmouth, UK, is a high rise, high density housing estate built by local authorities in the 1960s.
The aim of the project was to create an improved environment to benefit the health and wellbeing of residents, providing comfortable, safe and thermally efficient homes for many years to come.
Residents were not using their electric heating, as it was too expensive.
This was leading to issues with mould, damp and condensation, causing poor living conditions.
A huge retrofit of Wilmcote House was carried out, using a combination of several products and systems.
This included a ROCKPANEL cladding façade system, and a combination of ROCKWOOL external wall and flat roof insulation, together with a selection of our fire protection products.
